This reversible, nonslip pad protects both carpet and hard floors. One side is fabric, made from post-industrial recycled material, for use on carpet; the other is a blend of natural and synthetic rubber for hard floors. Thick, cushioned material reduces rug wear and makes vacuuming rugs easier and is especially recommended for hand-tufted and -knotted rugs. Place fiber side up on all hard surfaces, such as wood, tile, marble, concrete and laminate, and rubber side up on carpeted surfaces.
