CanDo® Sup-R Mat® exercise mats are high quality closed cell foam exercise mats that are tough enough for clinic, school and fitness center. Mats can be hung for storage with rubberized grommets (except for the 40″ wide Jupiter and Saturn mats). These latex free and phthalate free mats have a soft cushioned feel. Closed-cell NBR foam provides excellent elasticity, energy absorption and resistance. Mats are ribbed on both sides for anti-skid traction when in use, and ventilation when in storage. The mats are treated with anti-microbial material that is triclosan free. The mats float in water and can be used for hydrotherapy (do not use as life saving device; when in water always use with adult supervision). CanDo® Sup-R Mat® exercise mats are tear proof and scratch resistant and do not take a compression set.
