The Emanuele Bianchi designed Car Seat Protector is constructed with extremely durable polyester "canvass", the underside is made with an anti-skid mesh, and with the two ingenious neoprene belts, the two loose corners are solidly anchored to the seat. If you have an older car, or one without headrests, the adjustable belt is long enough to fit around the seat “shoulder” to keep the Seat Protector in place and your car interior safe.
