This super-tough Treadmill Mat is made of durable blown PVC, which protects floors from heavy exercise equipment and sweat. The blown PVC means the mat has a slight loft for cushioning, dampens vibrations and muffles noise. The mat is ideally sized for treadmills, elliptical trainers, rowers or general stretching and exercise. The cushioning in this mat makes it useful as an anti-fatigue mat for prolonged standing in the home or shop.
