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.
As your baby grows, adjust the 15-position headrest and harness in seconds to create the perfect fit. When it’s time for booster mode, simply tuck away the harness straps and buckle. With cooling channels, premium padding and built-in arm rests, your child will love the ride!
