It all starts with the first ride home. Then, there’s the first family outing. The first ride to daycare. Soon, you’ll be driving them to their first play date or soccer game. Throughout every change and milestone, you can count on one constant for your journey: the Britax® One4Life® all in one convertible car seat.

    • Great car seat
3 kids later and this is now our 3rd one we have purchased. Very easy to install and uninstall. Easy to clean. Easy to get kids in and out and set up safe for drives. We'll built and comfortable. Our oldest one is 4 years old and we have had no issues. We have a spare graco car seat we just tried getting bye with for our newest child and it is no where near as nice or easy to use. Had to just purchase another one of these! ... show more

    • Favorite seat! Read for fit tips
Review Image by RaeMars23
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 ... show more

    • The only car seat brand we will ever buy for our kiddos! Only cons are the weight and width.
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! ... show more

    • Highly recommend
Review Image by artzone
I just purchased this car seat. First off How it looks: beautiful love the style comes in many colors and styles i did the one 4 life click tight ( it is actually true it installs tightly). Supper soft and easy to follow instructions. What features: well I purchase this for easy installation and it also looked very comfortable too when it arrived it had many cushions and air netting on the sides for to breath. Side button with one push and easy to adjust tilit It was easy to find the buttons all labeled side and under the seat. Pros: easy to read and understand, easy to adjust and installation was a breeze. Once installed correctly it dosent move at all very impressive as I have had many car seats and they always move a little even once installed correctly this one was zero movement highly recommend for safty. Con well I don't really have any yet it is so far everything I hoped for. So weight: well it is on the more heavier side but it's not any heavier than Carring a baby carrier with base. It is solid to carry and solid once buckled. Other qualities it also is approved for other transport such as a plan if you wish to fly. What I love is the tilt feature and how it grows with your child, easy to install and read direction on the car seat visible and it is in two languages. The cushions for the head is very comfortable. Highly recommend for baby on up however I already pass the baby stage carrier and purchase this after my child was already one. It can even use for infants up to 10 years old Again highly recommend ... show more

    • Favorite car seat!
Hands down the favorite car seat we’ve bought. So easy to install, and we love the sides that are mesh & allow air throughout the seat. Our baby finds it super comfy & we are very pleased!

    • Very nice car seat!
Color: Raven Black Style: One4Life
Bought this for my 2 year old and now again for my 1 year old. It should last them forever. Its very big and cozy. Only downside is that the straps get twisted often but I feel like that's an issue with every car seat for some reason. One of the reasons we chose this brand is that its supposed to be free of toxins like fire retardant. Installation and removability is super easy and I feel very confident that my kids are safe in it. I bought it when it went on sale so definitely worth the price! ... show more

Easy to install. The material is soft. It is a super sturdy car seat. My son loved it when he first saw it and even wanted to sit in it while learning the mechanisms of it. Lots of into on YouTube.

    • Yes yes yes
I love this car seat and am getting ready to purchase a 2nd one for my daughter. I love that my kids will only need one car seat since this one grows with them. I love that it has a metal frame foe safety. It's comfortable and easy to install. I like how my kids can remain rear facing for a longer period of time. It is heavy but I feel that it's very safe, comfortable and durable for my child. I like how I can strip it down and wash everything. This is the brand that I will stick with. ... show more
