"Get two seats in one with the Safety 1st Crossover Belt-positioning Booster Car Seat. The perfect booster for growing kids, the Crossover 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. The pad removes from the seat and is both machine washable and dryer safe. A thorough wash is just a machine cycle away."
