High-quality material: Carpet non-slip underlay made of polymer PU, high temperature resistance, no deformation, easy to restore, durable. The triangular design of the rug provides strong adhesion and does not loosen easily. Washable and reusable: Washable and reusable non-slip mat for carpet. If it gets dirty, simply wash stoppers with soap and water and let it air dry. After cleaning, the non-slip mat becomes sticky again. Easy to use: Place the white surface on the bottom of the rug and the other side of the anti-slip mat on the floor. After placing on the floor, apply pressure from above and smooth the non-slip mat along the surface. Note: Make sure the rug and floor are clean and dry before laying. Non-staining and odorless: Carpet non-slip underlay is made of high-quality reusable PU gel without odor. The non-slip rug in contact with the floor uses a polyurethane gel adhesive that leaves no residue on the floor and does not damage the floor. Extensive compatibility: The non-slip mat is suitable for all types of carpet (except rubber-backed or latex-backed carpets, as the non-slip mat does not adhere to these materials). Effective on wood, tile, marble, concrete, and vinyl floors.
