## Customer Reviews

### ⭐⭐⭐⭐⭐ Love Britax!
*by M***C on July 1, 2025*

This car seat is incredible. After moving up from an infant car seat, we started with the rotating Chicco car seats and the rotating feature was the only thing I liked. It never felt fully secure, and at just 14 months my LO’s legs were already scrunched up.The steal frame seat on the Britax makes me feel so confident in my baby’s safety. The installation is so quick you’d think you did it wrong if it wasn’t for how secure it felt. The padding is so plush and comfortable. It’s ridiculously easy to adjust as your baby grows and it automatically adjusts the straps as well as the back of the seat at the click of a button. So easy to tighten and loosen to get LO in and out. I also appreciate the removable cup holders to ensure you truly can fit multiple car seats across your back seat bench. Lastly, and yes least important, the color is gorgeous. Truly the only thing that could make it better is a rotating feature but from my obsessive research, they seem to notably feel less secure. I’d rather my babe be safe at the slight inconvenience for me getting him in. I’d say the value for price is incredible.

### ⭐⭐⭐⭐⭐ Favorite seat! Read for fit tips
*by G***. on July 16, 2025*

My car seat hater enjoys the car much more in this than his infant seat. My 3 year old has one too and we love how comfortable they are, the less strict accident policy (had to replace a Graco extend 2 fit twice in 6 months bc of their replace in any and all accidents policy), that you can machine wash the cover with light detergent and how easy they are to install. Very high quality car seat that's very easy to adjust!CARSEATS WILL NOT PROTECT YOUR CHILD IF USED INCORRECTLY:-Top of chest clip should be level with armpits-Straps should come from below the shoulders rear facing and above the shoulders for forward facing-Slack should be removed from the hips, then tighten just enough so you're unable to pinch the straps at the shoulder vertically-DO NOT add any inserts, strap covers or head positioners that didn't come with your seat, they are not crash tested for your seat and will void the warranty in the case of an accident-Nothing should be attached to the seat or its straps (like binky clips, toys etc)-Wash per your manual-Rear face until absolute minimum of 2, it's their bone development that matters most-If you go see someone to help you install your seat make sure they are CPST (Child Passenger Safety Technician)-READ YOUR MANUAL)The group Car seat Safety on Facebook is extremely helpful

### ⭐⭐⭐⭐⭐ The only car seat brand we will ever buy for our kiddos! Only cons are the weight and width.
*by N***L on July 17, 2025*

I have recommended this car seat to sooo many of my friends! If you have ever used the Click Tight system you know exactly why! This is the absolute easiest car seat to install/remove and you get the tightest installation EVER! I really love that the car seat is so sturdy and well built! There are so many safety features built in too! We upgraded to the One4Life with our last kiddo from the Advocate. One of the best features that I didn’t know I needed was the cup holders! I love that Britax added them onto this car seat! This car seat has so many pros! There are a few cons however in our opinion. The car seat is VERY heavy (which is great for safety but heavy to move). The other con is that it is very wide (again this is great for safety but we are not able to go 3 car seats wide in the backseat because of this). Even with these 2 cons we will never use another brand of car seat!
