The Diono Connect3 RXT 2-in-1 High-Back Booster is a versatile and innovative car seat solution designed for families needing 3-across seating in most mid-sized sedans and larger vehicles. Its patented slim-fit design (less than 17 inches wide) ensures compatibility 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 combined cup/snack tray provide convenience for backseat snacking, while the convertible backless mode ensures years of use as your child grows.
