Easy to install safe carseat
[This review was collected as part of a promotion.] We are expecting baby number three and have been concerned about fitting three car seats into our car. Enter the All4Stages Slim 4-IN-1 car seat! What appealed to me about this seat was its slim design as we have never used a slim convertible car seat and it seemed like the best option to meet our needs. We have been very impressed with this seat thus far! It was incredibly easy to install which is ideal when transferring a seat between cars (which we sometimes do for grandparents). I also found it super easy to navigate between the various “modes” taking it from infant to rear facing, etc with ease. We have had lots of experience with various convertible car seats and this installation was one of the easiest in my experience. It’s a sleek looking car set that not only impressed me from a comfort standpoint, but also appears to be very safe for our new baby. The best part: it fit alongside our other car seats so that we have peace of mind when driving our three children. This car seat will be with us for a long time and I am thankful we have this option for a newborn through their booster days. Thanks to the Stellar Product Testing Panel for providing me with this car seat.

Easy convertible car seat!
[This review was collected as part of a promotion.] I received this as a part of Stellar Panels testing program.
This car seat is absolutely slimmer than the average car seat. We currently just upgraded our 3 year old to this as she was still in a rear facing nuna. It fits her slim body and she loves facing forward. The cup holders are not in the way to the door or center console in comparison to the nuna. We also have a 6 year old in another graco high back booster using the seatbelt path and this is slimmer than that one. The 6 year old did not fit into it comfortable as the headrest was pretty slimming for a boys head and he did not like that. Our daughter is much smaller and we’ll see how she grows into the headrest.
When installing, the straps were tangled up when trying to use the latch system and readjusting the belt buckle at the bottom but was actually super easy to maneuver and figure out. After that mix up, it was a breeze to install and super light weight again also compared to the nuna. So this will be super easy to pass between my husband’s car and mine.
We are actually in the talks of expanding our family and this a factor considering we have a smaller suv. So we’ll see how this could fit if we switched the 6 year old to another slim option.
Overall I was skeptical when you see this “slim” options as a first time parent you don’t even know what’s considered slim or not, lol, but it was awesome to receive this and confirm that I will be purchasing another in the future!

Affordable comfort
[This review was collected as part of a promotion.] We need to be able to fit three car seats across our middle row (2024 Honda Odyssey) and the Evenflo All4Stages Slim 4-in-1 convertible car seat allows us to do that! It measures at 16.9” wide which is definitely a selling factor for those with multiple children. It is lightweight and very easy to install. The latches are solid and the seatbelt synched with ease. The four modes and 12 height adjustments allows this car seat to be used for all ages, and for all percentiles. The infant insert is nicely cushioned, providing a stable yet soft area for newborns. You know your infant is secure in this seat, for sure. Our toddler who is 3, weighs 45 lbs and is 42” tall, fit comfortably forward facing. The cup holders location is a nice touch as they’re more towards the front vs the sides as with other seats, which allows my toddler to be able to actually reach her cups vs me having to do it for her. The best feature about this seat is the fact that it grows with your child! You can get one seat and know that it’ll last for the duration of your child’s needs.
Thanks to the Stellar Product Testing Panel for providing me with this car seat! I am confident in Evenflo and trust them with the safety of my children.

Grows with your baby
[This review was collected as part of a promotion.] The Perfect 4-in-1 Convertible Car Seat – A Game-Changer for Parents
I cannot recommend this 4-in-1 convertible car seat enough! It is truly an all-in-one solution that grows with your child, making it a smart investment for parents. Designed to accommodate your little one from the newborn stage all the way through toddlerhood, this car seat is versatile, practical, and built to last.
Why I Wish I Bought This Sooner
I previously used the infant seat from the same brand, which was comfortable and well-made. However, looking back, I wish I had just gone with this 4-in-1 option from the start. While the infant seat served its purpose, it was limited to the first year. This car seat, on the other hand, is designed to adapt as your child grows, saving you money and hassle in the long run.
Comfort & Safety – Designed with Your Child in Mind
Comfort is a top priority for me, especially since my daughter usually dislikes car rides. To my surprise, she has been much happier in this car seat. It offers excellent support for her, whether she's rear-facing or forward-facing, and the design prevents her head from drooping forward when she falls asleep – a huge plus for those long drives. It feels incredibly safe and well-padded, which gives me peace of mind as a parent.
Compact Yet Spacious
At first glance, the car seat looks bulky, but don’t let that fool you. I drive a small car and have two car seats installed – one for my 3-year-old and this one for my 1-year-old – and they fit perfectly. It’s actually more compact than the previous car seat I owned, and it doesn’t take up as much space as I expected. Despite its compact design, it provides plenty of room for my child, so she’s never uncomfortable.
Easy Installation
What truly sets this car seat apart is how easy it is to install. I’ve struggled in the past with other car seats, especially when it came to threading the belt or securing the seat tightly, but this one is a breeze. Even though it’s on the heavier side, the setup process is straightforward and stress-free, which is such a relief when you’re juggling multiple kids.
High-Quality Construction
The build quality is outstanding. You can tell this car seat is made to last for years. The materials feel premium, and the attention to detail is apparent. It’s a bit heavier than other car seats I’ve owned, but that weight comes with the reassurance of durability and safety.
A Worthy Investment
Yes, this car seat is an investment, but it’s absolutely worth it. Instead of purchasing multiple car seats for different stages, this 4-in-1 option has you covered from infancy through the toddler years. In hindsight, I could have saved money by skipping the infant seat and going straight for this one.
If you’re looking for a car seat that combines safety, comfort, and convenience while adapting to your child’s growth, this is the one. Whether you have a small car, multiple car seats to fit, or a child who’s particular about comfort, this car seat checks all the boxes. It’s an excellent choice that makes traveling with little ones so much easier – and I highly recommend it to any parent!

Amazing Convertible Car Seat – Perfect for Growing Families!
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel, I had the chance to try the All4Stages Slim 4-IN-1 Convertible Car Seat, and I’m so glad I did! Initially, I planned to use this seat for my infant, but the moment we unpacked it, my 2-year-old daughter fell in love with it. She climbed in, declared it her throne, and refused to give it up—tears included! So, we decided to let her use it, and it’s been a game-changer for our family.
The slim design is a standout feature. We have a midsize SUV, and this car seat fits seamlessly in the back alongside my older child’s booster seat, with room to spare for another passenger. It’s so nice not having to wrestle for space or feel like the backseat is overcrowded.
The four modes of this seat are incredible! Right now, we’re using it in the forward-facing harness mode for my toddler, but I love knowing it will grow with her as she transitions to a high-back booster and eventually a backless booster. It feels like a smart, long-term investment that meets her needs now and in the future.
Installing the seat was straightforward, even with a toddler eager to “help.” The instructions were clear, and I appreciated the easy-to-use LATCH system. Adjusting the seat for the proper fit was also a breeze. The headrest adjusts with one hand, and the straps slide effortlessly to the perfect position. This was especially helpful since my daughter is at that in-between stage where she’s growing like a weed!
The comfort level of this seat is unmatched. The padding is plush, and my daughter loves the cozy feel—she actually asked to sit in it even when we weren’t going anywhere! The dual cup holders are a bonus, keeping her water bottle and snacks within reach on long drives. Another feature I adore is the removable, washable cover. It’s a lifesaver for moms like me who deal with spills and messes regularly.

Car Seat to grow with your child!
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel, I had the privilege of trying the Evenflo slim convertible 4 in 1 car seat! This car seat is slim, but bulky enough to make your child feel secure and safe. My child felt high up and on top of the world and very secure in his new seat! Being able to have a rear-facing seat, forward-facing seat, booster with a back and no back is such a relief for time and money sake. Not having to deal with all of the changes in the car over and over and buying many car seats over the years with a child makes this car seat so worth the investment! Install was easy and worked well, just make sure you get it nice and tight and to the right reclining position if forward facing. My son was nice and snug in his new seat, but also very comfortable for anything that came his way. Evenflo, way to go on this one!

A Car Seat that will Last!
[This review was collected as part of a promotion.] This car seat is not only safe but also functional. I love that it has four modes that will be able to accompany my daughter as she grows up. Currently, my daughter is two years old, so she is rear-facing. The installation in rear-facing mode is very simple, and it takes less than five minutes. The car seat itself has many stickers/labels on it along with a clear manual to make the process easy. Even if you have zero experience with car seat installation, the manual combined with the clear illustrations make the process a breeze.
This car seat is also slim, so I don’t feel like I am losing a bunch of space in my back seat. I am currently pregnant, so I needed a car seat that could fit alongside my infant’s car seat. I also appreciate the fact that the car seat itself weighs a reasonable amount, so I’m not struggling to install it if I need to switch cars.
My toddler loves to snack in the car, so it is very important to me to have a car seat that can be easily thrown in the washer. The fabric on this car seat comes off very easily, and it is not hard to put back on. The cup holders are also dishwasher safe, so I can give the seat a deep clean whenever necessary.
As my daughter gets older, she will eventually be forward-facing, and I love that I will not have to buy another car seat. The forward-facing mode along with the rear-facing mode has multiple options for installation, so you can choose whichever option makes the most sense for your situation.
Thanks to the Stellar Product Testing Panel for providing me with this car seat!

Great all stage convertible carseat!
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this car seat! As a parent of a 6-month-old, 18-month-old, and 3-year-old, the Evenflo All4Stages Slim 4-in-1 Convertible Car Seat has been a fantastic addition to our family. Its four configurations—rear-facing, forward-facing, high-back booster, and no-back booster—cater to each of my children’s needs, eliminating the hassle of purchasing multiple seats.
The slim 16.9-inch width is a game-changer, allowing us to fit three seats comfortably across our backseat without compromising safety or comfort.
Safety features are top-notch, meeting or exceeding federal standards, and the removable canopy is perfect for shielding our youngest from the sun during rear-facing rides.
Installation is straightforward with the SecureTight system, making transitions between vehicles effortless.
Overall, the All4Stages Slim offers versatility, safety, and comfort, making it an excellent investment for growing families.

Transitions from Newborn to Booster
[This review was collected as part of a promotion.] I had the chance to try out the All4Stages Slim 4-IN-1 Convertible Car Seat, and it’s been a great experience. This car seat is designed to grow with your child, which means it can be used from infancy all the way through booster seat age. The slim design is a huge plus, as it doesn’t take up too much space in the car, making it easier to fit other passengers or car seats. It takes up less space that a similar style car seat.
The installation was straightforward, and the instructions were easy to follow. I also appreciated the adjustable features- like the headrest and harness, which made it simple to get the right fit.
The padding is soft and comfortable, and my child seemed happy and secure. I especially love the amount of padding which is removable, depending on the age of your child. The cupholders snap in very securely, which is great when you have an antsy toddler who wants to rip something out of it. I felt like a very sturdy design.
Overall, it’s a reliable and well-thought-out car seat that offers great value. Thanks to the Stellar Product Testing Panel for providing me with this car seat to review!

Great Slim Fit!
[This review was collected as part of a promotion.] My favorite feature is the the slim design that fits perfectly in my backseat, even in my two door sedan. It’s ideal for families needing more space or compact cars.
With four modes (rear-facing, forward-facing, high-back booster, and backless booster) it will grow with my child which will ultimately save money.
Installation was quick and easy with the LATCH system, and adjusting the harness to fit my child was hassle-free. I really appreciate how user-friendly it is.
The extra padding and side-impact protection are great for comfort and safety, especially on long trips. The breathable fabric keeps my little one cool, too.
Overall, I’m very impressed with the All4Stages Slim 4-IN-1 Car Seat. It’s safe, comfortable, and versatile - definitely a great choice for growing families!

Awesome car seat at a great price point
[This review was collected as part of a promotion.] I received this seat for free in exchange for my honest review from Stellar product reviews.
I think this seat is a great value with a comfy fit for little ones. I have an 18mo who is in size 24m clothes - so he's slightly on the chunky side. We took a very long 1 week road trip with this seat and overall for the price point it seems like a great value. While I used it only rear facing, I was really happy with the size (narrow and compact for use with multiple children or in a smaller vehicle), it was stylish and my baby seemed really comfortable on the long trip. I am a very by the book seat user, and I loved how the padding around the head cradled him in the seat. The seat was easy to install and easy to adjust which I think is really helpful for first time parents.
3 points of consideration for a potential buyer (in order of severity):
1) the shoulder straps are very very close to the head padding which adjust up and down. For the RF mode, it was a little tricky to fit the shoulder straps just at or under my baby's shoulders... and that made fitting the seat to him safely a little tricky. I worry this may be an easy miss for inexperienced parents... and for that I took off 1 star. I did find it easy to adjust to seat while the baby was in it... which made finding the right spot a little easier.
2) the directions mention a level for easy install, but I could not find it anywhere... and while I feel OK about the recline of the seat, I've installed and reinstalled many seats, and the vehicle was easy to install in ... so again, I worry this would be an easy miss for a new parent or grandparent.
3) the head padding is very generous and my 18mo (who does have a big head...) was just stuck between them with very little leeway on either side. I hope a 4 in 1 seat would have a lot of longevity so I am not sure how he will fit in 6m or 1 year, but I think this narrow fit (on the inside of the seat) could be a huge plus if your baby is smaller or tends to be less chunky.
4) the 2 cup holders are narrow and great for standard size cups but my baby's wide straw cup didn't fit securely. This doesn't matter to me, but if it matters to you, now you know :).
Overall for the money and longevity of this seat, I think this is a good option and I love the narrow external measurements (so hard to find with a multi-stage seat!), and I'd recommend it - just take your time and be patient when fitting your baby to the seat.

Room for two and toddler in the backseat again!
[This review was collected as part of a promotion.] Our family is thrilled to finally have a car seat that leaves room for two other passengers to sit comfortably in our backseat. Other car seats take up more than one space in our backseat, only leaving room for one other person. This was usually fine but became frustrating when we tried to bring friends along on our adventures. The All4stages car seat takes up less than one spot in the backseat, so we can now take two friends on adventures again. My big girl loves her new car seat. The padding seems comfortable and the design looks sleek and modern. One thing I really like is that my daughter can actually get her cup out of the car seat cup holder while we’re driving! We’ve had problems with cups getting stuck when using other car seats. I took off a star because it was a bit challenging to install, but otherwise we’re happy with this seat and looking forward to bringing it on an upcoming vacation. Thank you to the Stellar Product Testing Panel for sending us this seat to try!

Comfy riders and peace of mind
[This review was collected as part of a promotion.] I received this seat from the stellar testing panel. We tested this seat in two modes so far: forward facing our 4 1/2 year old in the third row of a Yukon xl, and rear facing a 2 year old in the middle row. The seat sits slightly higher than other comparable models, which is a plus for our third row passenger. He tends to get car sick, but being able to see out the front window in this higher seat was definitely a positive feature! The seat installed easily and I love the belt path where you secure the straps of the seatbelt when installed with the seatbelt vs latch. This thing wasn’t budging while testing for movement along the belt path! The straps are easy to adjust for height and tightness. The chest clip does feel cheaper/thinner than what we are used to, but as far as keeping the harness in place, it does the job. The cupholders are also a flimsier plastic but I’m glad to report that they are big enough to accommodate a regular sized drink cup and of course, a yummy snack on the other side. As far as comfort, the four year old says it is very comfy. I do notice that the padding around the head is a bit narrow, so maybe not ideal for larger-headed children. In the third row of the Yukon, it fit nicely next to an older child in a booster seat with plenty of room for a larger child in the middle of the two seats to fit safely and comfortably.
Adjusting the seat from forward-facing to rear-facing was simple and easy, installation still a breeze, and I feel the same about the security of the belt path, A+ on that! As a rear-facing seat, this slim fit convertible was great, it was even slimmer than an alternative we were using previously. Installed next to another rear-facing seat and a booster seat on the other side of that one, it fit very well in the middle row of the Yukon xl without touching the neighboring car seat. It was a nice comfortable ride for the two year old! Installation, removal, and adjustments were very simple and resulted in no frustrations of not being able to get the right angle or tightness of the seat in the car or the child in the harness. It feels secure, is easy to get a proper fit, and has nice padding for each stage.
Overall, I would definitely recommend this seat for this price point!

Multifuncional Car Seat Must!
[This review was collected as part of a promotion.] As a mom of a 2 year old and a 1 year old, I was excited to try out the rear facing feature for my youngest and letting my 2 year old give it a go in the forward facing position. I will say I was not a fan of the rear facing position for my youngest. She looked a bit uncomfortable and it was a weird angle to get her in and out of the car seat. Fortunately for us, my 2 year old gets to use it in the forward facing position. She looks very comfortable in it and the car seat looks very well padded so it gives me peace of mind having her strapped in it.
On top of it looking comfortable for my child, I love the slimness of the car seat. I drive a minivan so we have an abundance of space but it being slim, makes it easier to have someone ride in the middle row with them.
When it came to installing the car seat, the latch install was a breeze. I love the new latch design on this car seat. It will come in handy when swapping this car seat between cars. I also liked how easy it was so adjust the headrest for my kids.
Thanks to the Stellar Product Testing Panel, my kids will be able to use this car seat as they grow older. I'm excited to use the booster feature in the future.

Easy to clean, easy to install, works well!
[This review was collected as part of a promotion.] I received this car seat from the Stellar Product Testing Panel.
The first aspect I noticed about the All4Stages Slim 4-In-1 Convertible Car Seat was how easy it was to install. The other car seat I have I can barely fit my hand through to pass the seat belt through, and I have fairly small hands. We didn't need to spend a lot of time setting up the car seat for our daughter. It probably took me longer to undo the old one then to install this one.
Our daughter, 18 month old, is pretty chill so she seemed to enjoy the right and it fit her well. Although, looking at her riding around in it, she didn't seem quite as comfortable with the other. I think this has to do with the large head rest that is attached. It seems to maybe block her view a little.
One thing I don't love is the front clip it has a push button which I can not undo with a single hand and for a strong enough young kid could be more easily undone than the pinch clip.
The car seat does its main function and I had zero worries about her being safe in it. The back strap that hooks into the back seat and the seatbelt space had it cinched down.

Slim seat for small space!
[This review was collected as part of a promotion.] I was given this car seat to try as part of the Stellar Product Testing Panel. I installed this in the back of our BMW 328i xdrive, and I will say installation was a breeze. I usually make my husband install our car seats but I had no issues doing this solo! I was able to latch it without any trouble and it fit so much better than my toddler’s bulky car seat. It works great behind the driver’s side and allows my husband more leg room up front, something he had given up with our toddler’s car seat. My son is long and seemed comfortable when in the car seat. I do love how it’s a car seat that can grow with him, he is still rear facing and I feel like he will be comfortable as he grows until he is ready to forward face. The only part that stuck out to me was the headrest felt a little too large for the seat, but that didn’t seem to bother him. I think this car seat is an affordable option for those with smaller vehicles, without compromising safety for their little one! Thanks for letting me try this product!

Definitely Slim Fit - Great for Most Kids
[This review was collected as part of a promotion.] I received this car seat from the Stellar Product Testing Panel, and I was very excited to try it out. We have four children (ages 5, 3, 1, and newborn) so we are no strangers to car seats, and I was eager to see how this would compare to our others.
The All4Stages Slim 4-IN-1 Convertible Car Seat can work from the newborn stage all the way until the child is out of car seats and boosters entirely. That is a great feature for cost savings and for the sake of not having to store extra "stuff" since kids grow so quickly. That being said, we have always opted for an actual infant seat for our newborns because we value the ease of being able to pop the baby's seat in and out easily, especially since we live in a place with cold winters. However, that may not be an important or necessary feature for others.
My favorite feature about this car seat is that it truly is "slim fit." I have seen other seats that claim to be slim fit but would be very crowded in most vehicles and/or would not be able to fit three car seats across which I think is sort of the litmus test for a true slim fit car seat. Since we already have 4 children in car seats (and hope to continue to grow our family), having a true slim fit seat is essential. We won't be able to fit them all in our van otherwise!
The downside of the seat being truly slim is that it might be a tight or potentially uncomfortable fit for children with a broader build or an older / bigger child. That would be something that each parent would have to evaluate individually. For smaller or younger children, I actually think it's an asset since I personally feel more at ease when my kids don't have a lot of extra room in their car seats. I have rented car seats before when traveling that have seemed unsafe since my kids have had so much extra room on either side of them.
A couple other features that I like about this car seat are:
-The cup holders because they are not easily removable. In some of our other car seats, the cup holders are often rolling around on the van floor because my kids can unscrew them way too easily. It's nice to have them be removable (which these ones are) for cleaning purposes, but I don't want them so easy to remove that my kids can take them out themselves.
-The amount of cushion / padding. I had each of my kids try the seat out, and they all seemed comfortable and supported in the right areas.
-The ease of installation. The instructions are very straightforward, and the seat feels secure when installed.
All in all, I think this is a great seat and at a much lower price point than some other 4 in 1 seats on the market. The slim fit of this seat is a desirable feature, as well, assuming that it fits your particular child.
I would recommend this seat to friends or family members looking for an economical option that allows for other car seats to fit side by side or to allow for a more comfortable seating arrangement for passengers who may be riding near the car seat.
Thanks for the opportunity to try it out!

One seat for your child to grow with!
[This review was collected as part of a promotion.] I received this car seat from Stellar Testing Panel in exchange for my honest opinion. The first thing I noticed was that it felt light even in the box. When I was opening it, I found it shocking that the car seat didn’t have a bag or any cushioning in the box- just the car seat. I would want my car seat to have come with some sort of protection from being stacked and tossed around on trucks. I love that this truly is a car seat that will grow with your child. The four different positioning allows this to be a one time investment per child. It is easy to install when put in the backseat without an additional car seat or one more. Unfortunately for us we have three children and need three car seats at once. I was excited at how slim the car seat is. However, it did not fit between our other car seats. We are giving it to the grandparents but it doesn’t work for us. I believe if we had three slim seats it would fit. The car seat is sturdy and convenient. It comfortably fit our two month old in the infant position, forward facing for my 3 year old, as well as high back booster for my 5 year old. The cup holders are a nice touch but made it too narrow for my 5 year old. They are flimsy. Overall it is a great value for your buck but has its flaws.

Beautiful, safe, and space saver!
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this car seat to try out. Upon receiving this car seat and opening the box you can tell that this car seat is comfortable and made of great quality. The first thing I noticed was the head and neck support it provides beyond infancy which is important to me, especially with a toddler who falls asleep in the car frequently. I also noticed that this car seat is aesthetically pleasing with a great design. I also love that the seat is useful for all stages and I won't need to purchase another car seat as my child grows.
Installation was easy and the booklet it came with was easy to read to ensure safety. I did not like that it lacked the bubble level. Having the bubble level gives me an increased sense of security that the car seat is installed properly. It provides a level line which is fine but I found it hard to exactly match. Nonetheless, it was easy to ensure that the car seat was installed safely and securely.
Once my child was in the car seat, the ease of loosening and tightening the straps was the best I ever encountered. On cold days when I wanted to get it quickly done it was a breeze!
My child seemed extremely comfortable in the car seat. He would happily go in and let me strap him in, indicating to me that he was comfortable. It comes with two cup holders, providing a place for both a drink and a snack. Sometimes my toddler would just use it as toy holders which is great too!
As far as the material goes, the inner material is soft and seems very comfy. It comes out easily and can be thrown in the wash. The outer material on the other hard is rough and I found it hard to spot clean. Overall, the material was fine.
If space is something that you need for your family, this is the car seat to get. The car seat design is slim and took up very little space in my car. I would easily be able to fit two additional car seats or two adults comfortably in my backseat. This is great if you have a large family or even just for outings. It is important to note that even with its slim design, my toddler was comfortable and the car seat definitely has room to grow. Overall I recommend this car seat for all stages of your family's life!

Great seat for small cars with one caveat
[This review was collected as part of a promotion.] Summary: Great car seat for infants, small toddlers, and small cars. The 16.9” frame would allow for 3 across installs or more room for other passengers. The head rest is a bit bulky and I don’t think it would be too comfortable for kids with bigger heads.
Full review: The shipping and packaging of the car seat was great. Minimal waste and the car seat was fully ready to go straight out of the box.
I loved the look of the car seat’s slim design and modern black fabric cover. It came with tons of optional padding which would be great for smaller infants. I’m using this for my two year old so I removed all the padding. One slight concern was discoloration of one of the outer components (pictured). The cup holders are square which I’m sure was intended to save space but it makes the holder slightly too small for my daughters water bottle.
The instructions were clear and direct so I knew exactly how to install the car seat. Rear facing install was pretty standard using the lower anchors. It was easy to get a tight installation. I was shocked at how small it looked in my back seat. We drive a Toyota Tacoma and already had a slim car seat and this one looked much slimmer. It was also smaller front to back so we got a few more inches of legroom for the seat in front! My toddler is 2.5 years old and in the 50th percentile for height and weight so she is exactly average sized. She fits great in the car seat rear facing; my only concern is the head rest is really bulky and doesn’t leave a ton of space for her to mover her head around. This may become problematic in the future when she gets bigger. The upside to this is higher side impact protection and she’ll definitely have head support if she falls asleep but it is a con as far as awake time comfort.
Overall I was so thrilled I received this car seat from the Stellar Product Testing Panel. Having multiple kids means space saving products are a MUST. I’m excited that this will last for years to come and it’s a low maintenance easy to clean product.

Slim Design, but Some Trade-Offs
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with the opportunity to try the All4Stages Slim 4-IN-1 Convertible Car Seat.
The slim design of this car seat is definitely its standout feature. It fit very well in my 2012 Subaru Forester, allowing the passenger seat to slide all the way back and even recline slightly—something that my current car seat doesn’t allow. This feature is a game-changer for us, as it means my husband no longer has to sit in the backseat.
My son, who is 14 months old, used the rear-facing mode at positions 3 and 4. Compared to our current car seat, this one is more upright, which might be a plus for some families but felt like an adjustment for us.
Installing and adjusting the seat, however, was more challenging than I anticipated. One of the straps got twisted right out of the box, and I struggled to fix it. The padding also felt awkward to manage when trying to get everything aligned properly. On the positive side, I appreciated the ease of adjusting the shoulder straps—you simply slide the back up or down, which eliminates the need to detach and reattach the straps.
While the slim design creates more space in the front, it also makes getting my son in and out of the car seat quite difficult in the rear-facing position. It’s a tight squeeze, and transferring a sleeping child would likely be very challenging. Additionally, the bulky padding at the top seems to limit my son’s view out the window. I also found the button for loosening the straps to be frustratingly hard to reach.
That said, the seat does seem well-made and of good quality. My son appeared fairly comfortable during our drives, even though the seat’s upright position and minimal space doesn’t initially look very cozy. I can see this car seat being much more enjoyable to use once we switch to the forward-facing mode, as it would eliminate some of the tight rear-facing constraints we experienced.
In summary, the All4Stages Slim 4-IN-1 Convertible Car Seat excels in its compact design, which offers more space in the front seat—a major win for small cars. However, the trade-offs in ease of use and rear-facing comfort might be worth considering, depending on your family’s needs.

Great for tight fits!
[This review was collected as part of a promotion.] I was given this car seat to try as part of the Stellar Product Testing Panel, and decided to try fitting it in my 2017 Subaru Forester directly next to my child's VERY large center-installed rear-facing convertible car seat. Despite the tight fit, installation (rear facing, using LATCH) was a breeze, and this seat miraculously and securely fit, despite being installed right next to a beast of a seat! It truly is slim, and getting a secure LATCH install was easy breezy. I think for folks who are trying to get a three-across install (or two, plus the occasional passenger), this is a great option. It's also good looking!
My toddler will be 3 in April and is 29 pounds and almost 38 inches -- so, standard size but tall for her age. (I tried my hardest to capture a photo, but toddlers will be toddlers, and she fights me every time I try.) The narrowness of the seat didn't affect her comfort at all, but the narrowness of the headrest seemed to panic her. I am someone who intends to max out rear-facing height and weight limits, and my usual car seat (which is designed to offer more comfort for longer rear facing) does seem to offer more legroom for my kiddo. Pros and cons to that -- the All4Stages definitely was easier to fit behind our front seats than our usual, which we struggle with (as my husband and I are also tall and require lots of legroom).
I'd also like to mention that some of the features feel a little cheap in comparison to the seat we use (for example, the snack cups) and I personally feel more confident in my installs when a car seat features the "bubble" level, where this one has a line that I have to ensure is parallel with the ground. (My kiddo's infant seat had this, and it sent me into a panicked tizzy every time!)
Because I'm not prioritizing narrow and shallow (behind front row) fits in my car, I will continue to use my current seat, as it offers a bit more space for my kiddo to stretch out when rear facing, but overall the All4Stages is a great option for people trying to squeeze a lot of kiddos in the backseat!

Affordable One-Stop Shop for Versatility
[This review was collected as part of a promotion.] Slim Design and Backseat Fit:
The slim design worked wonderfully in our SUV backseat. We had the seat installed rear-facing, alongside two other forward-facing car seats, and all three fit comfortably. While the installation process wasn't overly difficult, it was a bit more cumbersome compared to my other car seats.
Four Modes and Versatility:
The four modes are a fantastic feature, offering a long-term solution as the seat grows with my child. We’re currently using it in the rear-facing mode, and I’m confident it will continue to meet our needs when it’s time to switch to forward-facing. It truly feels like a one-stop-shop car seat!
Comfort and Adjustability:
The cushy head support provides a snug and secure fit, keeping my son comfortable during every ride. He always seemed cozy and content in the seat. Adjusting the straps and achieving the proper recline were both simple processes, and the adjustable headrest is incredibly easy to use. It ensures a perfect fit for his current height and is equally convenient to adjust as he grows.
Standout Features:
One of the most impressive aspects of this car seat is its ability to adapt as your child grows, making it suitable for every stage—from newborn to older toddler. The four modes provide seamless transitions between rear-facing for infants, forward-facing for toddlers, and eventually booster modes for older children. This versatility eliminates the need to purchase multiple car seats as your child grows, making it both a practical and affordable solution for families.
The seat’s adjustable headrest and harness are designed to grow with your child, ensuring a proper and secure fit at every stage. I was particularly impressed with how easy it was to adjust these features as my son grew, saving time and effort. Additionally, the included cushy head support cradles newborns snugly, providing comfort and security during those early months, while still being supportive enough for active toddlers.
The built-in cupholders are also a thoughtful addition, perfect for toddlers and older children to keep snacks and drinks within reach. With these features, this car seat truly stands out as a one-stop solution for long-term use.
I received this car seat from the Stellar Product Testing Panel.

Good car seat with some good and bad
[This review was collected as part of a promotion.] I was given this car seat to try as part of the Stellar Product Testing Panel. This car seat was easy to install in all four modes. Tried the seat on our 40 lb 4 year old and our 20 lb 1 year old. The seat was easy to set up in all positions and some of the smaller parts like the buckles and liners were east to move around. The latch storage was better than other car seats. The back liner was odd. It was too long when used for an infant so had to be folded and left a weird gap. The hear rest was very large when compared to other seats. The head rest liner used for infants was very comfortable. The chest buckle was a little hard to undo. The seat was very easy to recline into the right position. The seat did not feel slimmer than other seats, it was higher for the children though. It did seem not as deep as other seats. We tried the seat in two different cars, and SUV and minivan and it fit well in both. Overall a solid seat that seems a little over priced and has some features we did not like.

Quality seat with multiple install options
[This review was collected as part of a promotion.] This is a quality car seat with some key features, but the install is a little difficult.
The fabrics are thick and comfortable! They feel very luxe, and my daughter loved climbing in it even once I opened the box. I love that the cup holders are included, and snap in easily. The mechanism to recline the seat is very intuitive and easy to use. Having the level indicator by weight on the side of the seat was extremely useful during setup. The latch setup was the easiest I've seen on a car seat, and I love that it came ready to use right out of the box.
The slim design held up to its name and the profile fit very easily in my backseat (small crossover hatchback vehicle.) You could probably fit 3 across easily, considering it doesn't infringe on the middle seat at all!
The seatbelt installation takes some maneuvering though. My daughter is a little older, so I feel more comfortable using the belt than the latch system. The instructional video makes it seem easy to access the belt path under the fabric, but I couldn't do that with the cup holders installed already (since that's listed as the first step in the video.) While I could do it by feel, I imagine this might worry new parents who might be unfamiliar with how to setup car seats this way. It also means that moving the seat in and out of a car would require more effort to re-install. Ultimately, this wouldn't be an issue if the cup holders were easier to remove, but I haven't found a way to unclip them once in. This did take me quite a few times to get a tight fit where the seat didn't move, so that's mainly why I docked stars.
The harness straps were easy to use though, and I really liked the style of the shoulder strap pads. They made it easier to know when a strap was twisted, due to the slimmer design.
Overall, this is solid option for a family that wants a seat that will grow with their child and offer multiple recline/install options. Based on how easy it was to use the recline and latch setup, it would be a great option to use from the infant stage. It may take some comfort with car seat installation to setup rear-facing with the seat belt though, and would be better for families that don't plan to switch it in and out of vehicles often. The fabric and slim profile make it a great quality option for families that need to fit multiple seats in more compact vehicles. Thanks to the Stellar Product Testing Panel for providing me with this car seat.

Just Okay
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this car seat! I have been testing the Evenflo All4Stages Slim 4-in-1 convertible car seat since it arrived. The seat arrived in minimal packaging, nothing inside of the box aside from the plastic the seat was wrapped in, which did seem odd and slightly concerning. Upon first look the seat looked nice but upon further inspection it just didn't meet my expectations. For the price point of the seat, the fabric seems like it won't hold up well over time, which is an issue when thinking of the longevity of the seat and its multiple uses. The fabrics seem thin and easily damaged. The cup holders, while a nice addition, don't seem to be very functional as the manual states not to use hard containers inside of them, like water bottles. The plastic of the holders seems flimsy and thin as well. I did appreciate how it fit into my car both forward facing, rear facing and three across. The recline in the rear facing position was really nice too. I wish it had a belt lock tight type of set up to make installation a little easier and faster. It took me a little bit longer to make sure the seat was as secure as possible with the seatbelt. Even with adjustments I felt like it moved too much for my liking on my leather seats. It fit both my rear facing and forward facing children well and they both seemed comfortable riding in it. My forward facing child's main complaint was that his head "felt squished" with how narrow the head rest was. He also was not a fan of not being able to store with plastic water bottle in the cup holders. Overall the seat is just okay, it is an all in one seat which is a bonus but I think to be able to use the seat for its entire intended life span, new covers would be needed as replacements at an added cost. I feel that for the price of the seat, there are better options in the same or lower price brackets.
