Safety 1st brings revolutionary Air ProtectTM Side Impact Technology to your family with the Complete Air 65 Convertible Car Seat. Safety experts agree: Keep children rear-facing longer and keep forward-facing children in harnesses longer. The Complete Air 65 keeps your child well protected through two separate stages: from 5-40 lbs. as a rear-facing infant car seat and from 22-65 lbs. as a forward-facing toddler car seat. With up-front harness adjustment and easy-adjust headrest youll appreciate the convenience features offered by the Complete Air 65 Convertible Car Seat just as much as the added safety.
