Mats are made of 100% virgin polypropylene.  Hollow polypropylene tubes are woven together to form an attractive and durable mat. Cleaning is easy with just some water or a few sweeps from a broom. Mildew is never a problem because the woven construction allows the water to drain.  Each mat is light and can be folded into a very compact size for easy storage. Size 9’x9’.
