All in One Car Seat by Britax

One4Life takes your child from birth to big kid with Britax Safety and ClickTight Installation. It easily 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.

As your baby grows, adjust the 15-position headrest & harness in seconds to create the perfect fit. When it’s time for booster mode, simply tuck the harness into the built-in storage compartment. With cooling channels, premium padding and built-in arm rests, your child will love the ride.
