Diono Connect3 R 2-in-1 High Back Booster, Slim Fit 3-Across in Many Mid-Sized Sedans and SUVs, for Children from 40-120 lbs., Lightweight with Cupholder, Black Storm

The booster built for growing families

Whether you're driving to school, heading out on a road trip, or fitting three children across the back seat, the Diono Connect3 R 2-in-1 High Back Booster delivers the space-saving design, comfort, and confidence modern families need.

Designed for children from 40-120 lb (18-54 kg), it converts from a high-back booster to a backless booster, giving your child years of comfortable, belt-positioning protection as they grow.

Fits 3 Across Without Compromise

Less than 17 inches wide, the Connect3 R features Diono's patented slim design, making it one of the easiest booster seats to fit three across in many mid-sized sedans and SUVs. The EasyReach™ buckle access helps children buckle independently, making everyday travel easier for parents and kids alike.

Grows With Your Child

The DualProtect™ adjustable headrest and backrest offer 11 height positions to provide an excellent fit throughout every growth stage. When your child is ready, the seat quickly converts into a lightweight backless booster for continued use.
