The Diono Connect3 R 2-in-1 High-Back Booster is a game-changer for families needing versatile and space-saving car seating. Its patented slim-fit design (less than 17 inches wide) allows for 3-across seating in most mid-sized sedans and larger vehicles, making it compatible with other Connect3 boosters, Radian convertible car seats, and adult passengers.

Designed for kids weighing 40 to 120 lbs, this booster combines safety and comfort with features like an 11-position DualProtect head and backrest, a SleepyCheek ergonomic headrest for napping, and a 2-position reclining backrest with premium 2TexFoam padding. The removable cup holder and breathable design add convenience and comfort, while the convertible backless mode ensures years of use as your child grows.
