The #1-rated Chicco NextFit Convertible Car Seat is engineered with innovative functionality to fit your vehicle and your child simply, accurately, and securely. NextFit features a ReclineSure leveling system and RideRight bubble level-indicators to help achieve and verify proper angle in the vehicle seat. With nine recline positions, ReclineSure is designed to accommodate a wider range of vehicles in both rear-facing and forward-facing modes. Premium LATCH connectors and a SuperCinch force-multiplying tightener help achieve a secure installation with a fraction of the effort. (When it's time to switch from rear-facing to forward-facing, the LATCH strap passes easily through the built-in slide path for proper re-positioning.) NextFit also has integrated belt lock-offs for alternate installation with the vehicle seatbelt. NextFit is built to grow from newborn through preschool with removable infant body support, a two-position chest clip, six-position headrest, and no-rethread harness that can be tightened with one hand. To accommodate older children, the shoulder strap position is designed to widen automatically as the headrest is raised. NextFit has a steel-reinforced frame and is lined with EPS energy-absorbing foam for superior side-impact protection. NextFit is designed for use from 5-40 lbs in Rear-Facing mode, and from 22-65 lbs in Forward-Facing mode. This product conforms to Federal Motor Vehicle Safety Standard 213 and is FAA approved for use on aircraft.
