"PLUSH FELT CUSHION: Choose from three thickness options - 1/4"", 3/8”, and 1/2"" - offering various levels of a soft feel underfoot, sound absorption, insulation, and extra comfort for your area rugs in busy spaces. RECOMMENDED USE: This FELT ONLY rug pad is not intended to stop area rugs from slipping. These rug pads are crafted for use under area rugs that are anchored down by heavy items such as furniture, large household décor pieces, or heavier area rugs. LONG-LASTING PROTECTION: The durable felt protects your flooring from long-term damage, such as scratches, scrapes, punctures, other types of abrasion wear, and discoloration from your area rug backing. EXTEND LIFE OF RUG: Prevents area rugs from creasing, bunching, and wrinkling, and keeps your rug surface smooth on the floor to make vacuuming easier. (AREA RUG NOT INCLUDED) CUSTOMIZABLE SIZING: Simply score the surface and trim your rug pad with scissors to fit any area rug size or shape by cutting approximately 1-2 inch short of your area rugs perimeter."
