Infant/Child Car Seat - One Car Seat for Life!

One4Life accompanies your child from infancy to the big kid stage, featuring Britax Safety and ClickTight Installation. It transforms from a rear-facing infant seat to a forward-facing 5-point harness, and finally to a high-back belt-positioning booster. The ClickTight system is as simple as buckling a seat belt, ensuring confident and secure installation every time. The high-strength steel frame, crumple zone, and V-shaped tether work together to absorb crash energy effectively. Additionally, two layers of side impact protection envelop your child's head, neck, and torso for enhanced safety.
