Wonderful convertible seat!
[This review was collected as part of a promotion.] I'm always extra cautious when it comes to car seats because I take the most precautions when it comes to my kids' safety. I was very excited to be given this car seat to test!
First of all, this seat is roomy. My youngest got right in and sat down, and she had plenty of room to grow. We have a booster seat that sits in the same row, and there was still room for another passenger to sit between them, so the slim design really works for us.
We are still rear facing, so a seat that accommodates that is important to me. It was super simple to adjust the recline settings for the seat, too. A simple lever helps you recline, so finding the best and safest fit is a breeze. My husband, who never reads any manual, was able to install this car seat in just a few minutes. I double checked everything by the book, and it all checked out. The directions were clear and concise as well, so they are very easy to follow.
I love that it is an all-in-one seat too, so it has the high-back booster and can convert to a backless booster too. It would work from newborn to big kid, so that's super convenient!
It was very easy to strap kiddo in as well. The only thing my husband and I weren't huge fans of was the chest clip. It didn't feel quite as secure as other brands we've tried because it has a button on both sides that feels like it can slip out easier than I'd like. It still held her in place very well though, so it still gets all the stars from us.
All in all, I'd highly recommend this seat to anyone who was looking for a safe, easy-to-use, convenient convertible car seat! Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat!

Fits Three Across in Sedan!
[This review was collected as part of a promotion.] I am a big fan of this new car seat. We have been looking for a new car seat that would fit three across in our 2013 Toyota Camry, and this one made it possible (even with two cupholders!!!)! It was a snug fit and was a bit difficult to buckle the seatbelt with three across, but I got it done. Even the backless booster seat we formerly had in the spot of this car seat didn't fit this well. It's also worth mentioning that this seat fits well in our car in general. There weren't any big gaps against the seat to fix as I went to install it.
We are using this car seat in the forward facing harness mode for our four year old. She finds it comfortable and is excited to sit in this seat, so that's a big win. I find the chest clip a little but tricky to unbuckle and the plastic it is made out of seems a little bit flimsy, but the seat seems to fit her well overall. I think this car seat is heavier duty and sturdier than some we have had in the past, so that is also a plus. I also love the fact that this car seat has a no rethread harness, as I don't want to be unbuckling and reinstalling it every time I need to move the shoulder straps up. For me, this is an essential feature for a car seat to have. This seat advertised that it can be used with just the seat belt and as a backless booster. For us, using it three across will likely make it impossible for us to buckle and unbuckle our daughter every single time she gets in and out because it's too hard to reach down in to buckle the belt. With that being said, my eight and six year old children still use car seats with a five point harness, so I think we will be able to use this one that way for many years to come, too. Overall, this is a great slim carseat and is doing a good job of meeting our needs.
I received this product as part of the Stellar Testing Panel, but all opinions are my own.

Great value, good quality - slim car seat
[This review was collected as part of a promotion.] This is a great looking car seat, very sleek with clean lines and neutral colors. The materials are all high quality, but not elite quality. I love the lower anchors for installing the seat, it made it easy to get it installed and secure in our car to where I felt confident it was safe for our child. Tightening and loosening the seat belt/harness was smooth and simple. Smooth and simple are very important to me when wrangling my kids into their seats. The slim fit design is excellent, more space on either side without sacrificing much, if anything at all in terms of comfort. The levelling system might be my only complaint. When moving to different recline settings, you are required to somewhat eyeball lines on the side to see if they’re parallel with the ground. That seemed a bit arbitrary so I ended up using my own level to double check things. This wasn’t a deal breaker, because we won’t move the car seat to different vehicles ever. If I had to move it to a different car periodically, it would be nice to have a bubble level on it somewhere. Adjusting to different heights and settings for different size and ages of children is very easy.
Thank you to the Stellar Product Testing Panel for sending this car seat for me to test and review. I am confident my kids will get many years and miles of use out of this car seat.

[This review was collected as part of a promotion.] Thank you Stellar Product Testing Panel for providing me with this convertible car seat. This is a great product. We loved the slim design. It has been very hard to find a car seat that fits in the second row without compromising front row leg room. It also gives my kids more space when sitting next to the car seat which helps cut down on the backseat arguments. We love the fact that this car seat will grow with our child. He is getting close to being large enough to switch to the next mode and the process couldn’t be easier to change. It is also incredibly easy to adjust the settings to allow for the perfect fit. The material is high-quality and soft and my child always seems comfortable. It is also impressive how it offers such a large comfortable seating area with such a small overall footprint. Great product.

Another great car seat from Evenflo
[This review was collected as part of a promotion.] Let me start by saying, we already have two other car seats from evenflo (for my older two children) and I love them. So it wasn’t going to be hard to convince me to try this car seat!
We have three kids in a Honda pilot and this car seat fit with our other two car seats in the backseat. Installation was done by my husband (I assisted) and it was a pretty standard installation, not too difficult. Our littlest is an infant so I’m looking forward to seeing how he grows into it, I think it’ll be a comfy seat for him for a long time. For now he fits well in it and the canopy is a nice extra feature to block the sun when he falls asleep in the car. It gives me great peace of mind knowing we’ll be able to use this car seat for him for a long time! Well done Evenflo! And thanks to the Stellar Product Testing Panel for this car seat!

Great Car Seat
[This review was collected as part of a promotion.] I received this product through the Stellar Product Testing Panel.
This is my first time using an Evenflo brand carseat, and right away I was impressed with the fabric material used on the carseat. It seemed comfortable and was quality material.
This was also my first time using a "slim fit" style carseat and I like the space it provides around it. It provides more room for the driver 's seat to move back if needed. The sides are low so it is easier to lift my rear-facing one year old into the seat. It sits up a little more than her previous seat so her legs are already bending to fit. But this does make it easier to lift her out of the seat.
I love that the seat will grow with her and I will not need to purchase anything new as she gets bigger. I was able to wash the fabric and then install everything fairly easily.
Overall it is a great seat and I would recommend buying it!

Carseat Superstar
[This review was collected as part of a promotion.] The All4Stages Slim 4-in-1 Convertible Car Seat packs a big punch in a slim design. The carseat was incredibly easy to install into my vehicle. It provides you with multiple installation choices, my favorite right now being the latch system. The slim design allows more room, then other carseats, for passengers to sit beside it. The space saving design affords ample room to install additional carseats or boosters next to it if needed also. So many carseats overhang into the adjacent seat and this one doesn't! The All4Stages has 4 seat modes which means this seat will easily grow with my little one, the perfect forever carseat. Currently my child is still rear-facing. This seat is compact enough to easily fit rear facing while also being reclined to the perfect position for comfort and safety, without impeding the seat in front of it. This carseat adjusted smoothly and with ease. I was easily able to adjust it to the perfect fit for my kiddo. The harness adjusts easily and the height adjustment is a snap. In seconds it was just right for my child. I love that it has more padding than other carseats we have used so my child is snug, comfortable and safe. Thank you Stellar Product Testing Panel for providing me with this carseat, it's definitely our forever safety seat.

Super happy with this car seat
[This review was collected as part of a promotion.] I was lucky enough to receive the All4Stages Slim 4-in-1 Convertible Car Seat through the Stellar Product Testing Panel!.
This car seat fit in my backseat perfectly. It was a little bit thinner the the one we were using. To me that is a huge thing. I love to save space with a growing little one! It was very easy to install. It has 4 different modes, making it easy to change when we need to. We are currently in rear-facing mode. It will be very easy when we convert it. My kiddo is pretty picky so we are still in the process of fully adjusting it. I have to say- it has a lot more cushioning feeling and I was happy to see that. It’s going to be so much more comfortable for them when we travel. We’ve had the stomach bug so I wasn’t able to get a good picture of them I. It. But wanted to show it side by side with the one we are in the process of now getting rid of. (don’t mind the dog hair- pup is always in there with us). I’m super happy with this and am looking forward to a little more room for the pup! I definitely recommend this to anybody looking to save some space and still have it look nice!

It’s a keeper
[This review was collected as part of a promotion.] If you’re looking for a reliable slim fitting car seat, look no further! Although this car seat is slim and perfect for smaller back seats, they didn’t skimp out on the cushion and build quality so my 10 month old is very comfortable in this. Installation was easy and so was understanding how much to recline. I love that I won’t need to purchase a booster as my littles get older and that this all-in-one won’t expire for 10 years making this car seat an even better value. Thanks to the Stellar Product Testing Panel for providing me with this car seat.

Perfect for our growing family
[This review was collected as part of a promotion.] With an 8 month old in a reclined rear-facing seat, a 2 year old who is still rear-facing but wants to look out the window, and a 4 year old in a forward facing car seat, I can testify that the All4Stages Slim 4-in-1 Convertible Car Seat can do it all and will continue to grow with our family through the years when we need a booster. It fit easily with two other car seats in a three-across configuration in our small SUV. The installation was a breeze and took less than 5 minutes. It was easy to adjust the straps and height of the headrest for children of different sizes. While the seat has a slim design, all kids found the seat to be comfortable and happily rode in the car seat. There is plenty of padding and the ability to adjust the recline ensured a safe and comfortable ride.
My kids were most excited about the cup holders which we do not have in any of our other car seats due to the constraints with a 3-across configuration. Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat.

Comfy seat that fits our small cars
[This review was collected as part of a promotion.] I was given this All4Stages Slim 4-in-1 Convertible Car Seat to try as part of the Stellar Product Testing Panel. My little one is 10 months old and about 16 lbs, so we were starting to think about transitioning her from an infant car seat to a convertible car seat. This car seat came at a perfect time for us. We used this car seat exclusively in the rear-facing fully reclined position.
Quality: The All4Stages Slim car seat is well constructed with nice, comfortable materials. Even though it was her first time in a convertible car seat, my little kiddo adapted to the All4Stages Slim quickly and was comfortable enough that we used it on a 6 hour road trip less than a week after we received it. She loved it! We had no issues with it throughout the entire trip, and my little one seemed comfortable in it the whole time.
Installation: I only installed it using LATCH anchors, but installation was fairly simple. The tightening strap required a fair amount of force to tighten all the way, but with some firm pressure and a little bit of wiggling, I was able to install the car seat in a couple minutes. One minor inconvenient detail with the car seat that we received is that it didn't come with a bubble level to determine the proper recline for the car seat. The installation manual didn't make it immediately clear whether or not our car seat had a level, so I spent some time trying to locate it. The level included on our seat requires you just to eyeball the level, which was adequate but not the most precise. Along with that, another slight inconvenience was that, in order to change the recline level of the car seat, it needs to be completely uninstalled before changing the recline angle and reinstalling it.
Fit: My wife and I both have small compact cars, so the size of the car seat was an important consideration. For both of our cars, the All4Stages Slim in the most reclined rear-facing mode fit in the passenger-side rear seat with the front seat moved all of the way forward (with about an inch to spare). We never had to install it side-to-side with another car seat, so I can't speak to the width of the seat, but there was plenty of room to fit a bag in the middle seat between the rear passenger and the car seat.
Overall, the comfortable seat along with the form factor to fit our small car makes the All4Stages Slim an excellent car seat that fits our needs, and my little one would agree.

Worth its weight in gold
[This review was collected as part of a promotion.] I don’t think anything can top the Evenflo 4-in-1 convertible car seat. I am SO in love.
I can’t get over how much time, money and stress it’ll save me in the long run!
I can use this with my newborn baby, all the way up until she’s 7 or 8 years old, probably more depending on the weight. It can be a rear facing car seat that you can adjust with the 12 options they have available, to a forward facing with a harness, to a high back booster, to a backless booster. I can’t believe I ever lived without this thing, and it’s a godsend for our quick growing babies. I’ve recommended it to several people, including my 3 siblings and they’re already looking into buying one for their kids! I will never have to worry about her comfort or safety ever again, which is something I’ve been stressing about recently. It’s slim which is great for those with multiple car seats, and doesn’t compromise the safety or comfort of anyone in the back. What a relief. The installation process was surprisingly straightforward and easy for the most part, and there’s a very detailed instruction manual that you want to make sure you don’t lose, as it will walk you through all the conversions. Adjusting the harness and headrest is also easy; I can do it with one hand which is a lifesaver when you’re juggling a baby or toddler.
This is an investment that is worth its weight in gold if you ask me. You won’t regret it.
Huge shout out to the stellar product testing panel for gifting me this car seat in exchange for my honest review!

Simple Set Up & Comfort
[This review was collected as part of a promotion.] I received the All4Stages Slim 4-in-1 Convertible Car Seat as a part of the Stellar Product Testing Panel. Right out of the box, I was impressed by the quality of the seat. From the padding to the buckles, everything is high quality. I found this seat easy to install, using the latches. With a small SUV and another car seat in the back, it’s nice to have a slim fit, which this seat provides. I am using it for my rear-facing child at the moment, but the instructions are very clear for using it in multiple modes. I am looking forward to being able to use this seat for years to come!

Great car seat, even for a smaller back seat
[This review was collected as part of a promotion.] I tested this product as part of the Stellar Product Testing Panel, and I’m so grateful that I was able to.
I drive an older Acura with a small backseat. I can’t very comfortably sit in the back and as such was very worried about upgrading my son out of a baby car seat and needing an adjustable one that leans back and needs more space.
I was so pleasantly surprised upon setting this car seat up that it fits and works perfectly in my car! With the thinner design, I think we could definitely still fit two other passengers (who are hopefully shorter than me) in the backseat.
My husband and I found this car seat a little harder to set up and align the line with the ground vs other methods we’ve seen, but once we got it in securely it seems really safe and secure. I am confident that my son is comfortable and happy and safe, which are all of my requirements for a seat. I love the cup holders and the ability to have this backward facing and tilted back more while he’s younger, but also to know this can grow with him and eventually be used for forward facing. We look forward to using this for many years to come!

Car seat review
[This review was collected as part of a promotion.] I was given this convertible car seat to try as part of the Stellar Product Testing Panel. I absolutely love this car seat! The slim design fits perfectly in my SUV. We have 3 other car seats, so space is definitely something we are limited on. The slim design of this car seat helps our set up without sacrificing safety. I feel like this car seat is extremely durable. I was worried with it being slim that it would feel less sturdy. That is not the case with this car seat. The set up was extremely easy and the switch between the stages was a breeze. I love that this car seat has cup holders on both sides. Our child is currently learning to use sippy cups. The cup holders on both sides help us give him two options for an easy grab. The padding is very soft and provides extra cushion for our little one on our car ride journey.

One and Done!
[This review was collected as part of a promotion.] This carseat is a dream for tight spaces. Its slim design allows easy access to the back area of the car in my vehicle, perfect for families with multiple children.
Installation was very easy for rear facing my very light 2 year old. The carseat is not awkwardly tall like many other convertable seats. It has the huge bonus of a no retethering design. You simply press the button and pull up, automatically getting your child into the correct belt position.
The 4 modes will come in handy when we transition to forward facing in the coming months.
And then in the years to come, it also has a backless booster mode that will be incredibly convenient!
Padding is plush and generous. I love the design and thoughtful process of the folded up extra padding for the lower back as my child grows.
Two cup holders is just fantastic, especially since the seat is slim and there is truly room for them.
I also want to point out that in forward facing mode there is still enough recline to keep a littles head from falling forward during those inevitable road trip naps!

Easy and secure slim car seat for families on the go
[This review was collected as part of a promotion.] The All4Stages Slim 4-in-1 Convertible Car Seat is the perfect car seat for families on the go. This lightweight, yet still sturdy, seat is super easy to install -- the lower anchor clips are easily accessible and quick to attach. It's so easy that my parents were able to install this car seat into their minivan on their own for an overnight visit without any trouble, and they easily navigated the harness, which we all know can be tough with a wiggly toddler! Despite the slim size, this car seat maxes out on comfort. Our toddler has a ways to go until he outgrows the rear-facing, forward-facing, and booster seat limits. We know it'll be a comfy ride for him given the plush padding and how easy it is to adjust the seat. My one complaint is that we found the cupholders to be a little small for some of our kiddo's wider water bottles, but that's barely a blip in the radar given how great the other features are. As native New Yorkers who often rely on car rentals, the small frame and simple installation make it easy for us to clip in and go in any vehicle, whether we're out for some weekend errands or for a family road trip. Overall, the All4Stages Slim 4-in-1 Convertible Car Seat is a great option that will grow with our toddler through the booster stage. Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat to test out and review!

Safe and comfortable
[This review was collected as part of a promotion.] I received the Evenflo All4Stages Slim 4-in-1 Convertible Car Seat to test as part of the Stellar Product Testing Panel. I have a Honda Civic, so the slim body is imperative. I need two car seats to fit comfortably for my kids. Installing the car seat was a breeze. I loved how they provided a QR code so I could watch a video on how to install. I also used the quick guide pamphlet they provided to double-check. What I love about the car seat is how well cushioned it is. My youngest says it's more comfy than his last one. My son has been able to unbuckle his chest latch on another car seat, and this one latches a bit differently. So far, he hasn't been able to squirm his way out. It puts me at ease knowing that my son is safe and secure while I'm driving. I love that this is an all-stages car seat and will grow with him.

Great car seat!
[This review was collected as part of a promotion.] Thank you to the Stellar Testing Panel for allowing me to test out this product! To my surprise, this seat was very light in weight compared to others I have used before; which made the installation process a breeze! It took only a matter of minutes. I absolutely love the way it fits into my back seat. Unlike a lot of car seats, it’s slim and doesn’t take up as much space. It makes it really nice if you have extra passengers that you need to put in your car. More room for everyone! My kids are growing up so fast, so it’s nice to have the four modes available to use as they grow. My son is continuously telling me how comfy the seat is. Comfort is key! No one wants to be uncomfortable on a long car ride! My only complaint would be that I feel like the straps are a little on the “thin” side, so they tend to get twisted a lot. Between the shoulder straps and the buckle clips, I’m constantly having to untwist them. Overall though, great car seat!

Excellent slim car seat
[This review was collected as part of a promotion.] When choosing a car seat for my child, my top priorities have always been safety, affordability, and ease of installation (I'm not very technical, so it was important for me to be able to install the seat myself if needed, without relying on my husband). With the arrival of our second child, another factor became essential — compactness. We drive a small car, and sometimes I need to sit in the back to comfort my youngest. Squeezing between two car seats in a compact car is far from comfortable. So, I was thrilled when Stellar Panel gave me the opportunity to test the All4Stages Slim 4-in-1 Convertible Car Seat.
I have two children — my oldest is almost 6 years old, and my youngest just turned 14 months. We decided to use this car seat for our older child to get more detailed feedback, but I love knowing that it can also work for my youngest if needed, as the All4Stages Slim 4-in-1 Convertible Car Seat is designed for kids from birth up to 10 years old. For our five-year-old, we installed it in the forward-facing with harness mode. At first, I was worried it might feel too snug and that we’d need to switch to the booster mode (which I usually prefer for older kids). However, my child feels just as comfortable in it as in his previous full-size car seat. In fact, he even mentioned that the All4Stages Slim 4-in-1 is softer and more comfortable. He also finds it easier to buckle and unbuckle the harness, which is a big plus for us since he used to struggle with the buckle in his old seat, making school drop-offs during carpool more challenging.
The car seat description mentions that the seat pad is removable and machine washable. I haven’t tested this yet, but as any parent knows, cleaning a car seat can become necessary at the most unexpected moments. I appreciate that the manufacturer made this process simple and convenient. Additionally, the seat comes with two removable cup holders, which is always a great feature.
And finally, as I mentioned earlier, safety is the most important factor for me. The All4Stages Slim 4-in-1 Convertible Car Seat meets federal motor vehicle safety standards. It also features the LATCH system, which not only makes installation easier but also reduces the risk of incorrect installation, enhancing overall safety.
For the sake of a thorough review, I also used this seat for my younger child for a few days in the rear-facing mode, and it worked just as well. My little one was comfortable, and I had no issues with installation or usability.
The All4Stages Slim 4-in-1 Convertible Car Seat checks all the boxes for me. It’s reliable, safe, easy to install and maintain, and space-saving without compromising my child’s comfort. If you’re looking for a car seat that meets similar criteria at a reasonable price, I highly recommend giving this one a try!

Convertible Car Seat
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat.
My baby likes his new car seat and so do I! I transitioned him out of his infant car seat into this one, and I’m happy with it overall.
Most importantly, this car seat is safe and comfortable for my infant. He is currently rear-facing and reclined all the way back. I like how I can adjust the recline position as he grows. He is on the smaller side, and hs never really liked being in a car seat, but he seems happy in this one and looks secure and cozy!
This was not the easiest car seat to install using the LATCH system. My very strong husband had difficulty making it tight enough despite using his body weight. The only other drawback back is that the chest clip doesn’t open very easily. Each time I’ve used the seat, it has taken me a few tries to open it.
This seat looks expensive (it’s very much affordable) and sleek. It has a lot of padding and it has not one, but two cup holders! It fits very nicely in my car and I love that it’s less bulky than other car seats.
This is a great car seat for anyone looking for a safe, good looking, affordable, car seat that will grow with your child well into his or her toddler years!

Slim, Comfortable, and Safe Car Seat
[This review was collected as part of a promotion.] I received the Evenflo All4Stages Slim car seat through Stellar Testing Panel, and I am very happy with the product. This car seat was able to easily fit between my two current car seats, allowing three rear facing across the row. It was super easy to install and feels super secure once the install is complete. The padding is comfortable and keeps my children comfortable even during longer car rides. I love the ease of lifting the head rest up without having to re-thread any straps. I will be buying another to have two in our second car so that we can have safe, comfy car seats in both cars!

Functional, safe car seat!
[This review was collected as part of a promotion.] I had very high hopes for this car seat, and am glad to say that it has exceeded my expectations! My daughter is 2 1/2 and still rear facing, so that is how we had ours set up. Compared to another slim car seat, this was so quick and easy to configure. It is slightly bulkier and a little heavier than our other one, but I appreciate that because it gives me peace of mind. It was super easy to install as well. I usually have my husband install them but this time I did it myself and was pleasantly surprised to find it so effortless to install. I have an older Nissan Altima and it fits in the row nicely. I sometimes have difficulty with car seats in my car, but no issues here. My daughter is so comfortable riding in it and I can’t wait to use it on our long car rides this summer! I am thankful to the Stellar Review Panel for allowing me the opportunity to review this seat!

All4Stages Slim
[This review was collected as part of a promotion.] I received the Evenflo All4Stages Slim Car Seat through the Stellar Product Testing Panel, and it has been a fantastic addition to our family. The slim design fits easily alongside other car seats or passengers, making it perfect for families with limited backseat space. The four modes—Rear-Facing, Forward-Facing, Highback Booster, and No-Back Booster—ensure it will grow with my child. Installation was incredibly easy, so much so that I almost second-guessed myself! The clear instructions were made even more helpful by the included QR codes, which led me to detailed video tutorials. The LATCH system was a breeze to use, and the seat adjusted quickly to provide a secure and comfortable fit. The padded fabric ensures my little one stays comfy, and the rear-facing recline feature prevents my baby’s head from falling forward during naps. The two things I wish were different are that the button to change the recline positions could be more accessible from the side—it’s a bit difficult to reach when the car seat is in the rear-facing position. I also wish the cushion for the buckle between his legs had an elastic that kept the two pieces together, as it tends to separate when I’m adjusting the straps. Overall, this car seat is versatile, easy to install, and keeps my child comfortable and safe. I highly recommend it for its long-term value, thoughtful design, and easy installation.

The only car seat you will ever need!
[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat! I am so grateful I was given this car seat for my toddler to use. The car seat was so easy to install and I love the slim design of it! I drive a Nissan Altima so the backseat space is limited but this is the perfect car seat because it is slim and safe. Passengers can sit in the back comfortably with the car seat. It also does not take up a lot of room in rear-facing mode so the front passenger can be comfortable in the front seat as well. I love the concept of the seat’s four modes. I won’t have to worry about getting another car seat for the rest of my child’s life! Right now, I still have my toddler in rear facing mode but I am happy to know she will be able to continue growing with this car seat and use it with ease. I was surprised with how easy it was to install. I used the latch system and it was two simple clicks! I also liked how there were installation videos on YouTube to go along with the paper instructions. These videos were very handy and helpful! The recline feature is a nice feature to ensure your child is safe and positioned correctly. I love how you can easily adjust the height of the back of the car seat as well so it best fits your child. The car seat material is good quality and easy to come off if needed to be washed. I also love the built in cup holders! This is a must for children! I love this car seat and think it is one of the best!

Comfortable, sleek car seat
[This review was collected as part of a promotion.] I’m extremely happy with this car seat. We live in LA, so we spend a lot of time in the car driving through traffic and my kids’ comfort and safety is extremely important to me. This car seat checked all of the boxes. It’s well padded in all of the right areas, so it’s comfortable for my little one. My older kids actually remarked it’s way more comfortable than our normal car seats, especially the head rests.
I was worried the slim design would make it too restrictive for my four-year-old, but after two weeks and many hours, he’s been totally comfortable. When he falls asleep on longer drives, the slim design is actually better because his head falls more easily on the headrest. Our back seat is particularly narrow because we have my daughter in a booster and my oldest has plenty of room in the middle seat. We used to have to scoot the car seats as far to the sides of the seats as possible to make enough room for the middle passenger, but this has helped significantly. You can see in the attached picture that my oldest has quite a bit more room on the Evenflo Slim car seat side than he does on the other side next to another full size booster.
I love love love the easy click installation of the latch straps. It’s by far the easiest way to install a car seat into the latch hooks. No hooks—just push until you hear and feel the click. And the latch straps automatically adjust to the right length, which is honestly one of my favorite features. Our car’s latch hooks are not the easiest to access, and this makes car seat installation so much easier. It also keeps the car seat really secure. Switching the straps to forward-facing from rear-facing took a little bit of effort, but once I figured it out, it will be much easier if I need to switch it back. The straps are easy to adjust and my son loves the extra padding on the straps. I also love that the straps move when you adjust the headrest.
The material is easy to clean. We’ve taken three trips to the beach and many more to muddy and sandy parks, but with a little vacuuming the car seat still looks brand new. My son is soon going to be too heavy for the latch system, and we will need to switch this car seat to a booster. I love that we have that option, and the option for a backless booster when we get to that point. I like that the backless booster option also has handles to make for easy carrying.
I received this product to test out as a member of the Stellar Product Testing Panel, and I am overall very happy with the seat.

Great Car seat with multiple seating options!
[This review was collected as part of a promotion.] The All4Stages Slim 4-in-1 Convertible Car Seat is a durable and sturdy option. My daughter is currently rear-facing with multiple tilt options, and the anchor system is quick and easy to install in the cars I’ve used it in. I currently only have one child so have not had the opportunity to test it when multiple car seats are in place. Its slim design is a great feature, and the padding around the head and back provides good support and comfort. The gender-neutral grey color is nice, and its sleek design is very appealing. The straps are simple to adjust and tighten, making it easier to use than other car seats I’ve had. The dual cup holders easily accommodate her water and snack bowls. However, my two complaints are that the cup holders are slightly out of reach for her when she's tightly strapped in and this car seat is heavier than some others I’ve used. Overall, I'm excited to use this car seat for several years as my daughter grows. A great perk is that it has a booster option, allowing kids to use it for a longer period before outgrowing it. Thank you to the Stellar Panel for providing me with this car seat to test and review!

Comfy, cute & slim for the win!
[This review was collected as part of a promotion.] We are a family of small toddlers and have the entire back row filled with 3 car seats. Having a slim convertible car seat for my youngest was a necessity for us. I appreciate the comfy seat and protection for his head. He falls asleep almost every ride so I can tell he adapted quite well to his new seat. Installation was so simple and I love the fact that he can grow with this seat and that it has 4 different modes. He uses it in rear facing mode and we will eventually use the other modes as he grows! The feature that stood out to me the most would be the side protection around his head area. The padding is nice and soft and was able to provide maximum comfort to my little one. Another fabulous feature would be if my older kiddos needed to use it for any reason I can simply swap the mode and adjust the their needs. The two cup holders on each side is such an awesome feature to have for any water bottles or cups so my son can have it within arms reach! Thank you to the Stellar Product Testing Panel for providing me with this convertible car seat!

The perfect slim design car seat!
[This review was collected as part of a promotion.] I was given this convertible car seat to try as part of the Stellar Product Testing Panel. I have been on the hunt for a slim design car seat, and this came at the perfect time. The All4Stages Slim 4-in-1 Convertible Car Seat is not only the perfect size, but it will also grow with my child. I have installed it stand alone and directly next to another car seat. It fit flawlessly and still allowed for an adult to comfortably sit next to the car seat. Using the video provided in the manual, it was very easy to install and adjust to fit my child’s size. I love the modern look of the car seat with its black upholstery and high end fabric finishes. The car seat is padded and comfortable for my child. It is definitely more snug than her other car seat, due to its slim design, but she seems comfortable in it. Overall, I would recommend this product to someone looking for a car seat that can be installed directly next to another car seat, or have an adult sit comfortably next to it.
