NOTE: A rug pad should be slightly smaller than the rug. RATED #1 NON-SLIP RUG PAD: This pad is the original non slip rug pad and the best RATED for all hardwood and hard floors! MADE IN THE USA OF FELT AND 100% NATURAL RUBBER: Unlike others, our pad is made in the USA with a U.S. patented needle-punched felt construction that prevents decomposition and shredding, minimizing odors even if damp. Thermal-set ridges on the upper surface, in an exclusive pattern of chevrons, running in multiple directions, enables the pad to grip the rug more effectively and prevents lateral motion in ANY direction. Pad backing is made of superior natural rubber formulation in a new, exclusive hexagonal "tire tread" pattern, puts more real rubber in actual contact with any bare floor, no matter how slippery, and provides the highest degree of non-slip traction - PURE RUBBER ADHESIVES! For the best in rug and floor protection, use this rug pad. SAFE FOR ALL FLOORS: Our pad will NOT stick to or harm hardwood, wood, tile, marble, stone, vinly, linoleum, concrete or radiant heat floors.
