Made of high density PVC, the rectangular-shaped mat provides rugged strength and a cushioning surface for added comfort. Dense mats absorb vibration, noise and impact caused when exercising on cardio equipment, so you won't worry about bothering your family and neighbours. The mat's smooth, clean surface can help prevent harmful floor and carpet dust from getting into the moving mechanical parts of exercise equipment. The super-tough, durable mat helps protect your floors and carpets from the damaging effects of heavy exercise equipment and debris from mechanical parts. 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.
