All Car Seats are Final Sale. 

The Britax One4Life takes your child from birth to big kid with Britax Safety and ClickTight Installation. It converts from a rear-facing infant seat, to a forward-facing 5-point harness, to a high-back belt-positioning booster. 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. And, 2 layers of side impact protection surround your child’s head, neck and torso.
