A nine-position extended headrest and easy transition to a belt-positioning booster accommodate years of growing. Features: - Assures protection: DuoGuard provides two layers of protection with a rigid shell and EPS energy-absorbing foam that surround the head and torso. The seat shell is also reinforced with a steel frame for superior impact protection. - Easy to install: The MyFit® is designed with smart functionality that makes it the easiest to install simply, accurately, and securely, every time. A four-position ReclineSure leveling system and RideRight bubble levels help achieve and verify proper angle in the vehicle seat. Premium LATCH connectors and a LockSure belt-tightening system with wide routing make it easy to achieve a tight and secure fit with LATCH or the vehicle seat belt. - User-Friendly Touchpoints: A padded, no-rethread harness with a one-pull tightener provides reassuring security for growing toddlers.
