The Britax One4Life All-in-One Car Seat takes your child from the first ride home to the big-kid years in one seat. It starts rear-facing for children 5 to 50 lbs, converts to a forward-facing harnessed seat for 30 to 65 lbs, and finally becomes a high-back booster for 40 to 120 lbs, designed to grow with your child for 10 years.
ClickTight installation makes a secure fit simple in three steps: pinch to open, thread and buckle, then click it closed. A high-strength steel frame, SafeCell technology and a patented V-shaped tether help manage crash energy, while the 15-position no-rethread harness and headrest, 9-position recline and machine-washable SafeWash cover make everyday use easy.
