Super-Stop Natural is made with natural rubber coating over a superior quality polyester fabric which gives the pad a rich, luxurious feel and supports the rug evenly to help retain its appearance. It features superior grip strength to keep rugs from sliding and slipping on hard surfaces, has a balanced, open-weave construction that allows maximum air circulation and makes vacuuming easy. Super-Stop Natural is treated with MSM-Fresh anti-microbial to inhibit the growth of odor-causing bacteria, mold, and mildew. It is fire-retardant and moth-proofed and can be custom cut to fit any rug size. Super-Stop Natural is guaranteed to maintain its "non-slip" properties for 10 years with proper maintenance.
