Britax One4Life Car Seat | Drift

All car seats and boosters are final sale. No refunds or exchanges.

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.
