Non-slip safety: The rug underlay prevents slipping and ensures increased safety in your home. It reduces tripping hazards, creases, and raised corners, while preserving the appearance of your room and making vacuuming easier. Note: Not suitable for rugs with overly padded backing. Quality materials: The set includes 8 rug grippers made of durable, heat-resistant, and warp-resistant PU polymer. Their triangular design provides a strong grip and prevents easy detachment from the surface. Note: Do not use on surfaces prone to cracking. Washable and reusable: The rug grippers provide strong grip on both sides without damaging the floor. If dirty, they can be cleaned with soap and water and then air-dried. After cleaning, their grip remains intact. Note: Ensure the floor is clean and dry before use. Easy to install: Attach the white side under the rug and the light side marked "on floor" to the floor. Press firmly onto the rug and smooth the adhesive surface. To remove or clean, slowly lift the pads. Note: Both the rug and floor must be clean and dry before application. Versatile use: This non-slip rug pad is suitable for most types of rugs and works on wood, tile, marble, concrete, and vinyl floors. Note: Not suitable for rugs with a pile, jute, or rubber backing, as grip may be limited on these materials.
