The Britax One4Life could be the only car seat your child ever needs, growing with her from birth to 120 pounds—while surrounding your child with safety features and making installation super-simple for parents at every stage.
The One4Life starts as a convertible car seat that can be used rear-facing up to 50 pounds and forward-facing up to 65 pounds, before transitioning to a booster car seat that allows your child to wear the vehicle seatbelt.
The Britax One4Life is made with a high strength steel frame and features SafeCell technology in the base of the seat crumples to absorb forces, as well as a unique V-shaped tether to help reduce movement in a crash.
The Britax One4Life is one of the easiest convertible car seats to install, thanks to the ClickTight installation that allows you to simply open the front of the car seat, thread and buckle the vehicle seatbelt, and close the door for a secure fit.
