Item # 10804


The Monterey XT is a full-featured, expandable high-back booster seat designed to fit growing children 40 lb to 120 lb. The adjustable head rest and deep, aluminum reinforced sides are lined with energy absorbing EPS foam for side impact protection. The shaped and contoured seat ensures the correct seating position and makes for a comfortable ride. A simple-to-use dial on the back adjusts the width of the seat to fit a child’s shoulders up to 20″ wide. The 11-position headrest gives ultimate flexibility and adjusts up to 6.5″ in height with one hand for an easy, precise fit. As a fixed-position booster, integrated LATCH connectors and front adjusters allow for a safe and secure installation in seconds (LATCH use is optional) and keeps the seat in position when not in use. Plus with wipeable fabrics and a removable, washable cover, the Monterey XT High Back Booster is easy to look after and keep clean. Also features 2 extra-deep cup holders and snack trays which fold away when not in use. Monterey XT can also be used as a backless booster and packs flat for travel and storage.
