The Graco Nautilus 2.0 3-in-1 Harness Booster car seat can be used from toddler to youth, keeping your growing child safe. With 3 modes of use, your child can ride securely with a forward-facing harness from 22-65 lb, a highback booster from 40-100 lb, and a backless booster seat from 40-120 lb. Its Simply Safe Adjust harness allows you to adjust the harness and headrest together as your child grows, with no time-consuming rethreading. You'll appreciate the strength of the steel-reinforced frame, 4-position recline for comfort and fit, and an updated, sleeker design. The booster car seat also includes 2 personal cup holders to help your little passenger enjoy the ride. The car seat is Graco ProtectPlus Engineered to help protect in frontal, side, rear, and rollover crashes.
