The Britax One4Life convertible-to-booster car seat grows with your child for 10 years—from 5-120 lbs and up to 63” tall.  It converts from a rear-facing infant car seat, to a forward-facing 5-point harness seat, to a high-back belt-positioning booster seat.

As the only all-in-one car seat with ClickTight installation, it’s easy to install in seconds, so you’ll know it’s installed correctly every time. A high-strength steel frame, crumple zone, and V-shaped tether help absorb crash energy and two layers of side impact protection surround your child’s head, neck and torso so you can travel in total confidence knowing your child is surrounded with Trusted Britax Safety and Full Body Protection.
