Car Seat Protector for Upholstery: Designed by OSA! Protect your vehicle's upholstery. Car seats and boosters are tough on upholstery! Most seat covers only guard against spills—our thick, padded shield prevents dents and abrasions to the seat and the backrest, too. The secret? A high rebound foam core. The non-skid bottom and ribbed top keep car seats in place. Includes handy storage pocket, tuck-in flap, and extended panel to shield your backrest.
