Let this solid rug pad be the wind beneath your rug’s wings. The no-skid rug pad is made of solid polyester to keep your carpet, and you, from slipping. The pad helps your rug keep its shape and protects it from the wear and tear of foot traffic by providing that extra layer between it and the floor. The underlay measurements are 58” x 90” so it fits 5’ x 8’ rugs. It's easy to use: just place the pad down and throw your rug on top to make it snug.
