Our Nautilus 3-in-1 car seat helps keep your child secure in a 5-point harness, from 22-65 lb. When your child is ready, it converts to a belt-positioning booster from 30-100 lb, then to a backless booster seat from 40-120 lb. The car seat is steel-reinforced for strength and durability, Side Impact Tested, and has Eps foam. There is also a one-hand height adjustable head rest, recline, and integrated cup holder and storage.
