Product Description

Shop smart and get two seats in one with the Pronto Belt-positioning Booster Car Seat by Cosco. The perfect booster for growing kids, the Pronto has an easy-to-adjust headrest that lets you give a custom fit to your child. When they're ready, the back removes, and you have a backless booster that's easy to transport and simple to store in the trunk when not needed. In either mode, the cup holder holds a drink or snack during the ride or hides away inside the seat when not needed.

With kids in the car, messes happen. Now, thanks to the easy-to-clean car seat pad, there's no need to stress. The pad removes from the seat and is both machine washable and dryer safe. A thorough wash is just a machine cycle away.

Cosco Pronto Booster Car Seat features:

  • 2 seats in 1: easily converts into a backless booster

  • Removable, machine washable seat pad

  • Adjustable headrest

  • Shoulder belt guides

  • Integrated slide-out cup holder

  • Meets or exceeds Federal and ASTM Safety Standards

  • Accomodates children from 40 - 100 lbs.

Comments about Cosco 1001228 Cosco Pronto Belt-Positioning Booster Car Seat - Ziva:

The only reason I ordered this product is because it appeared to be beige in color and was the type of booster I was looking for. When it arrived, it was actually gray, dark gray. Thank goodness my husbands vehicle is gray, or I would have returned it. This was a secondary booster so it was no big deal.
