One4Life takes your child from birth to big kid with Britax Safety and ClickTight Installation. 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. 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. A high-strength steel frame, crumple zone, and V-shaped tether help absorb crash energy.
