Our rug pad is the best quality underlay available, specially made from carpet fibers and finished with a rubber backing. As a result, it offers long lasting performance and deep comfort underfoot. Dual siding makes this pad usable with the felt side down on carpeted floors and with the rubber side down is perfect for any hard surfaces. It minimizes rug slippage to prevent unsightly bunching and assure greater safety. In addition, the underlay acts as a barrier that keeps rug bottoms from abrading underlying surfaces.
