100% Felt rug pad designed to add comfort and floor protection under rugs. Reversible for use on hard surfaces and carpet, ideal for uneven surfaces, and reduces puckering under heavy furniture. It can be cut at home to custom-fit any rug. Ideally, the rug pad should be cut approximately 1-2" short of the rug perimeter. Your rug pad dimensions will be a few inches shorter than the size of the area rug. This is NOT a defect nor is it the wrong item, the rug pads are made this way to avoid causing the rug to have a lip which would get in the way of walking, a door opening etc.
