About this product

The Britax One4Life All-in-One Car Seat is a convertible safety seat designed to grow with a child from infancy through booster stages. It features a high-strength steel frame, SafeCell® technology, and dual layers of side-impact protection for enhanced crash safety. The seat converts from rear-facing (5–50 lbs) to forward-facing with a harness (30–65 lbs) and then to a high-back booster (40–120 lbs), supporting use for up to 10 years. It includes a 15-position no-rethread harness, 9-position recline, and dishwasher-safe cup holders. The breathable knit fabric and premium padding provide comfort, while the machine-washable cover allows for quick cleanup. It meets FMVSS 213a and frontal impact standards.
