Kids grow up fast, and the Skyline 2-Stage Belt-Positioning Booster is designed to keep up. The high back provides extra head protection for kids up to 63” tall and can be easily removed for use as a backless booster. 2 layers of side impact protection include an energy-absorbing shell and a 10-position, quick-adjust headrest. It's thoughtfully designed to fit 3-across in most vehicle seats, while still providing spacious comfort for your growing child. 2 dishwasher-safe, removable cup holders keep drinks, snacks, and toys within reach and are a breeze to clean after each ride. Color-coded vehicle belt guides make it easy to properly position the vehicle seat belt. Quick-push lower connectors secure the seat in your vehicle when your child isn't riding, to protect other passengers. Best of all, your big kid will love the comfy & stylish soft knit fabrics.
