Made of high-density PVC, the rectangular-shaped mat provides rugged strength and a cushioning surface for added comfort. Noise-Reducing: Dense mats absorb vibration, noise and impact caused when exercising on cardio equipment, so you won't worry about bothering your family and neighbors. Clean, dedicated space: The mat's smooth, clean surface can help prevent harmful floor and carpet dust from getting into the moving mechanical parts of exercise equipment. Protect Floors Mat: Super-tough, durable mat helps protect your floors and carpets from the damaging effects of heavy exercise equipment and debris from mechanical parts. Exercise-Equipment Mat: This mat's thick padding works well under heavy fitness equipment, like larger treadmills, ellipticals, recumbent bikes, and cross-country trainers. It can also be used for general aerobics.
