Britax One4Life All-in-One Car Seat with ClickTight Installation + SafeWash Fabrics

The One4Life® all-in-one car seat and booster combo grows with your child from birth to big kid. It begins in rear-facing mode with an extended capacity of up to 50 lbs, allowing your child to ride rear-facing longer. It easily converts to forward-facing toddler mode (30-65 lbs) and belt-positioning booster mode (40-120 lbs).* Thanks to ClickTight technology, you can install the seat confidently every time. As your child grows, you can smoothly adjust the 15-position harness with just one hand — no rethreading needed. With thoughtful convenience features, premium comfort, and an all-in-one design, you can confidently navigate every stage of the journey with just one car seat — for life.
