I was lucky enough to receive this car seat as a part of the Stellar Product Testing Panel. Honestly, this car seat is a game-changer. When I gave birth to my now 9-year-old, having to make multiple car seat decisions as he grew bigger and older always felt overly stressful as a mother. At first, I was skeptical about having one car seat that would take me from birth to 10 years old, but that skepticism immediately faded away upon receiving the car seat. Everything about this car seat screams high quality and comfort. The fabric is so soft, and the fact it is machine washable and dryable is great since I want this car seat to look clean for many years to come. Install was fast and simple with the ClickTight system. I can't imagine going back to any other carseat without the ClickTight. Finally, perhaps my favorite feature of this car seat is that my youngest can stay rear-facing all the way until they are 50 lbs. Knowing that rear-facing is the safest position for them to ride in, this is a game changer. I have never had a car seat that could remain rear-facing beyond 22-35 lbs so this added peace of mind is such a benefit. I honestly can't recommend this car seat enough to any new mom. There are plenty of things new moms have to worry about, and knowing that this car seat can eliminate any sort of worry in the area of car seat safety for the next 10 years is amazing.

We are SO impressed by this new car seat! I had been comparing car seats to update my 2 year old so he would be able to rear-face longer (up to 50 lbs!) and we received this one to test out through the Stellar Panel product testing panel at just the right time. This car seat has surpassed all of my expectations! It is a “slim” design, but you would not know that by the amount of room he has to sit comfortably. I also have over 15 years of experience with a variety of car seats, and I have NEVER had such an easy time installing one. When I say this thing does not move an inch with the proper install, I mean it. I cannot budge it at all, which makes me feel so confident my guy is safe. I would have to say my favorite thing is the space he has, and the overall click-tight feature because of the fact that it feels so secure I don’t have to worry about him going anywhere at all. And knowing I can move this seat from car to car with very little “work” to achieve a proper install? Priceless.

Love love love this car seat! The fact that it is slim and an all-in-one car seat makes it the perfect forever car seat. I love the fact that it is so slim that it fits in my small Ford Focus yet I still have space for two other people. I have the car seat set up in the middle of my back seat and it works really well! The Britax One4Life Slim All-In-One car seat gives me the longevity I am looking for in a car seat. The fact that I can use it for my newborn or my toddler is amazing. I love that I can rear-face both of them for longer (up to 50lbs)! Currently I have been using it for my toddler and he seems really comfortable rear-facing. Adjusting the cushy straps and the padded headrest for him has been easy. The best feature of this car seat is how easy it was to install! The easy to follow instructions in the manual along with the ClickTight feature made the installation a breeze. Looking at the car seat, I thought installation was going to be hard but honestly, the ClickTight feature is amazing and I was able to install the car seat without yelling or cursing. Overall, I highly recommend this car seat. The attention to detail Britax gives to their products and the safety features makes this car seat worthwhile. My family and I want to thank the Stellar Product Testing Panel for providing me with this car seat.

We have been Britex One For Life fans from the get go, so having access to a slim version is like a dream come true. Thanks to the Stellar Product Testing Panel, I have been given the opportunity to try out this car seat, and I couldn't be happier with it! Our backseat space is limited, and while the regular One For Life worked well, things were cramped, especially if anyone else needed to sit in the backseat. With the slim, there is plenty of room without feeling like we are encroaching on the car seat or the safety of our child. It was incredibly easy to install, which is a big plus for us, and the instructions to install being on the side of the car seat is incredibly helpful. Adjusting it for my child was straightforward, and I love how much more comfortable the seat is in the slim vs the original! My son is in the high end of percentile for his height, so having a seat with extended rear facing ability was very important to us, and this meets our needs! We prefer to keep him rear facing as long as we're able, and were very happy with the limits on the slim! He's not cramped in the seat and fits very comfortably. It checks all of our boxes for comfort, safety and longevity of use. Overall, I am very impressed with how much space this seat saves without compromising safety, fit or comfort. It still maintains all the features of the regular One For Life, with a smaller footprint. I would absolutely recommend this seat if you're looking for one to grow with your child!

We've used a total of 5 car seats over the last 10 years for our 7 children. As you can imagine they have gotten a lot of heavy use over the years. The car seat we purchased for my oldest is expiring this year and we needed to find a replacement. By providence, the Stellar Product Testing Panel offered us a car seat to try out and we jumped at the offer. I must say I'm impressed with the durability and features. The three biggest perks are that 1) it is narrow (16.5 inches) and allows for a child to squeeze into the seat next to it, 2) it grows with the child, from a rear-facing newborn to a belt-positioning booster for my elementary schooler, and 3) it has plenty of leg room while rear-facing (we like to keep it rear-facing as long as possible). My daughter in the picture is 20 months old and has plenty of room for her feet. There are 9 positions and we can adjust 2 more over to gain even more leg room when we need. This car seat doesn't get installed like other brands I have used, and I needed to read the instructions to figure out how to install it (I also learned that vehicle latches are only rated to 65lb for the seat and child combined which means most forward-facing installations will need to use the belt). The instructions were easy to understand and once I knew the proper way, the car seat was very easy to install. This car seat is extremely heavy, I wouldn't be surprised if it is 2-3 times the weight of my other car seats. It seems very solid and durable and the weight doesn't concern me as I don't plan on taking it out of the van for many years. If I was transferring it to grandma's car when she takes the kids out or moving the seat around in the car for carpools I would reconsider using this seat. There are a couple of other nice features. The height and length of the straps adjust easily at the touch of a button. The (optional) cupholders are removable for easy cleaning. The recline position and switching from rear-facing to forward-facing is done with one button press, no rerouting straps necessary. I can't speak for how easily the cover comes off to wash but the cover separates at the bottom for easy vacuuming (already needed as you can see in the picture). My daughter seems comfortable sitting in it even for longer rides. I normally wouldn't pay extra for a car seat that can grow with my child as we've been handing regular car seats down to the next child and getting separate booster seats for the child that outgrew it. However, if I was in a situation where keeping one car seat for as long as my child needed made sense the Britax One4Life Slim All-In-One car seat seems like a solid choice and I would definitely recommend.

The Britax One4Life car seat is awesome! It’s actually slim so I can fit three car seats across in my back seat. The arm rests are low so my three year old son can climb in and out by himself. He loves the independence and I love that I don’t have to lift him in and out. The car seat was really easy to install - I didn’t even have to use the manual. I love that this car seat will grow with my son and can be converted into a high back booster seat when he’s ready. Wish this had been the first (and last) car seat that I used for my son. I was given this car seat to try as part of the Stellar Product Testing Panel.
