Walser seat cushions are a quick and effective means of protecting your front seats from the worst of the wear and dirt that will otherwise slowly degrade them. The front is made from a hard wearing matt finish foam-filled polyester, and the back is a non-slip black polypropylene. They're held in place with an elastic strap around the headrest, another strap around the seat back at low level, and if required a strap between the seat and the upright. They're well made, look good, and are comfortable to sit on - not too hot - and they stay in place very well.
