Veken’s rug pads are made with Polyvinyl Chloride materials. The pad’s signature grip will keep the rugs in place and prevent them from bunching and sliding during daily use. The rug pads protect your floors from normal wear and tear, high heels, kids playing, and much more. The open grid construction allows air circulation and prevents dust from settling under the rug. The rug pads also aid in preventing the floor from scratches that may occur during daily use. The additional thickness of the pad provides carpets and rugs with extra cushioning to elevate comfort in your home. The rug pad is also suitable for preventing futons, seat cushions, and mattresses from sliding, and for adding more cushioning as well. It is not recommended to use on carpet, vinyl, lacquered, acrylic, natural stone, porous, refinished surfaces, concrete, or heated floors. The size of this rug pad is 3x5 Ft, but it can be easily trimmed with regular scissors to meet the size and shape of your choice.
