Britax One4Life vs One4Life Slim — both grow with your child from 5 to 120 lbs, offering rear-facing, forward-facing, and booster modes in one sleek design. The Slim stands out with a narrower 17.5” width, making it a great choice for smaller vehicles or fitting three across. Both models include cup holders, ClickTight installation, SafeCell tech, and a steel-reinforced frame — so safety and convenience are never compromised. Same trusted features, just a slimmer fit. #BritaxOne4Life #One4LifeSl
