Enjoy safe travels from birth to big kid with the Britax® One4Life™ Convertible Car Seat. This car seat features 4 configurations, including rear facing infant car seat, rear facing toddler car seat, forward facing 5 point harness car seat, and forward facing high back booster seat. Start out with the rear facing car seat for infants and toddlers, then graduate to the forward facing car seat and booster car seat for preschoolers and big kids. ClickTight® technology makes it easy to install your new baby car seat with confidence. Simply open the seat, follow the path to thread the seat belt, buckle it, and click the seat closed. The One4Life™ all in one car seat is outfitted with a high-strength steel frame, a SafeCell™ crumple zone, and a patented V-shaped tether. The easy-pull adjuster lets you move the 15-position headrest and no-rethread harness at the same time, so you can find a secure fit in seconds. Quickly adjust between 9 recline positions and use the easy-read level indicators to find the correct angle. The Britax® One4Life™ comes with an easy-to-remove, machine-washable cover, and the knit construction is naturally flame-retardant.
