About this item

ALL-IN-ONE CAR SEAT: Designed to grow with your child for 10 years, this 3 in 1 car seat easily converts from a rear facing infant and toddler car seat (5-50 lbs) to a forward facing car seat with a harness (30-65 lbs) and, finally, to a high back booster seat (40-120 lbs) *Due to regulatory changes, weight and height ranges may vary by model; always follow the weight and height specifications listed in your product's user guide and on your product labels.

"4.0 out of 5 stars" - I am giving it a 4 star only because I LOVE the One4Life regular sized version better. Other than that... the clicktight install could make me give a 5 star anytime. I swear I don't understand how people have anything other than clicktight. I HATE borrowing people's car seats on vacation because if they don't have clicktight i cannot get them secured enough. But these are just so fast and effortless to install you won't be sweating and screaming at your kids.The colors offered for the Slim are why I tried this one instead of the regular size. I looove the colors! But I felt like my baby would flop his legs out of the frame of this car seat since it is slimmer, and with the regular he doesn't do that.It also feels more durable to me that the cupholders are built into the regular version, whereas the slim you have to install it. (PS there was no instruction on how to install the cupholders so I almost ended up breaking the darn thing until I found a way to do it on tiktok). Some people say they prefer the option to remove the cupholders since some kids try to put their feet in cupholders.... but i havent had that problem, and like i said my baby kept straddling the frame in a weird way that seemed unsafe to me compared to the regular size.But in general, the security of these britax one4life carseats is so obvious. They are so well built... I went and saw a Nuna Exec in person, which is meant to be the rolls royce of car seats at $800+ and i swear this Britax blew the Nuna out of the park in terms of looks and how durable it felt. I also heard the Nuna's are very hard to clean, and britax are so much more user friendly, and less expensive. I will never switch brands. I am a Britax fan for life now. I just hope they make the regular sized ones in cooler colors soon!The amount of time i put into researching this carseat was insane, because Im a crunchy mom haha no flame retardants was a big concern for me, and this one passes that test! It's also the best choice for moms with giant babies! My baby has always been 100th percentile, and the britax one4life (and the poplar i think too) are the best for height but also strap height. Bc sometimes babies can grow out the strap before the actual height if that makes sense. I want my baby to be safe rear facing for as long as possible, in a flame retardant free seat that is cozy, and this takes the cake!Oh also, my baby is happier in this carseat too. I've had him in graco's in the past when an airline lost ours and he would legit scream and cry. He seems so cozy in these. ANNDDD lastly, the way its sloped allows the driver to reach their arm back and assist (while looking in the camera i have by the radio in the car) to do stuff like pass a water bottle that has dropped or replace a binky. Ive tried in other car seats to do this and the heads are too oddly shaped to allow for it.Just buy this or the regular size and you will not be disappointed.
