Head and Shoulders above the Rest! The IIHS Best Bet KidFit Zip Plus Booster Seat boasts bonus zip-off cushions PLUS new quick-release LATCH for easy removal. Designed with 10 positions of DuoGuard protection, KidFit Zip Plus features a rigid shell and EPS energy-absorbing foam for head and body support throughout every stage with integrated side wings. Built for Protection, Stability and Comfort Premium LATCH connectors and a SuperCinch one-pull tightener stabilize the seat for easy in/out and keep it secured when unoccupied. The upgraded quick-release LATCH provides convenient one-hand removal from the vehicle LATCH system for easy transfer between vehicles for a portable booster seat. A contoured ErgoBoost Plus seat with triple-foam padding provides comfort and support in all the right places, and a 2-position backrest adjusts to mimic the vehicle seat position. The backrest is also removable to create a backless booster for older children. Convenient and Road Trip Ready KidFit Zip Plus also includes stylish, quilted seat and backrest cushions that easily zip on to provide extra padding and protect the fabrics underneath. They’re just as easy to zip off for cleaning or storage. All fabrics, including armrest covers, are removable and machine washable. Two dishwasher-safe CupFolders fold out of the way when empty for a narrow booster seat and are easy to remove for cleaning. A bonus storage console fits into either CupFolder to carry big kid necessities. KidFit Zip Plus is designed for children at least 4 years of age who can sit relatively still in the same seated position throughout the car ride, 44-57 inches tall and between 40-100 lbs. in high-back booster seat mode or 40-110 lbs. in backless booster seat mode
