Self-adhesive tape: Durable non-slip stair tread covers are perfect for indoor use. We use 6mm thick premium soft felt material, which increases the friction between the foot and the stair mat, and with the floor tape, your family and pets can completely prevent the slip.Easy Installation and Removal: Clean and dry your floor first. Remove the plastic back cover; just place the non-slip stair mat treads on your stairs and press down the interior carpet treads; if you want to move it or remove it without residue, just peel it off and leave it on the stairs. Washable and Reusable: Carpet stair treads are only hand washable; just remove the non-slip stair treads from your staircase and replace the carpet against the stairs after it dries naturally. The dog stair treads are perfect for preventing your dogs from slipping with the strong adhesive paste and reinforced felt thickness. The stair mats can be cut to size for all your needs.
