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. 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 rug pad is also suitable for preventing futons, seat cushions, and mattresses from sliding, and for adding more cushioning as well. Avoid Use On: Vinyl, lacquered, acrylic, natural stone, porous, refinished surfaces, concrete, stained concrete floors, or heated floors. It can be easily trimmed with regular scissors to meet the size and shape of your choice.
