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. SafeWash cover is safe to machine wash and dry. 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. The protective seat shell and foam-lined headrest help absorb impact energy and are designed to help keep your child's head, neck, and body safe. 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 away the harness straps and buckle. With cooling channels, premium padding and built-in arm rests, your child will love the ride.

Recommendation – Britax strongly recommends:

Children ride rear-facing to the highest weight or height specified

Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed

The top tether be used at ALL times when installing the child restraint forward-facing.
