One4Life takes your child from birth to big kid, surrounding them with trusted Britax safety.

More than just a convertible car seat, this car seat converts through 3 stages so you can use it with your infant as early as 5lbs and allow them to continue using it through all the stages of car seat use (which means up to 120lbs!): a rear-facing infant car seat, to a forward-facing 5-point harness seat, to a high-back belt-positioning booster seat.

With Britax's ClickTight installation, there’s no stressing or struggling. Seat belt paths are fully open, clearing the way for confident installation, and the automatic tensioner takes care of the tightening. A high-strength steel frame, SafeCell crumple zone & V-shaped tether give you total peace of mind while you travel. Mindfully-made from top to bottom, One4Life has a naturally flame-retardant cover with no added FR chemicals.

• Converts from a rear-facing infant seat (5- 50lb) to a forward-facing 5-point harness seat (22-65 lbs) to a high-back belt-positioning booster seat (40- 120lb).
