Each Canvas Seat Cover has been specifically designed to suit your specific vehicle type. These seat covers are made from 12oz canvas, but Ironman 4×4 have also added an extra sandwich layer of foam for your comfort, it also protects your seat and acts as a non-slip base. With side airbags now being incorporated in most new vehicle seats, Ironman 4×4 seat covers have a special approved and tested seam built into the side of the cover. Each seat is individually bar coded.
