One4Life takes your child from birth to big kid with Britax Safety and ClickTight Installation. It easily converts from a rear-facing infant car seat, to a forward-facing 5-point harness seat, to a high-back belt-positioning booster seat. The Cool Flow mesh fabric improves air flow, keeping your child comfortable for the ride. ClickTight is as easy as buckling a seat belt, so you can install with confidence, every time. Color-coded belt paths show you where to route the seat belt for each installation mode. Plus, easy-read indicators help you find the correct recline angle. A high strength steel frame, crumple zone, and V-shaped tether help absorb crash energy. And, 2 layers of side impact protection surround your child’s head, neck and torso. As your baby grows, adjust the 15-position headrest & harness in seconds to create the perfect fit. When it’s time for booster mode, simply tuck the harness into the built-in storage compartment.
