Slippery hardwood stairs? These carpet treads are a fantastic solution. They're made from soft, durable polypropylene and have a magic non-slip backing that grips your stairs without any tape, glue, or adhesives – and won't leave residue! The 'bullnose' design means they have a molded front edge that protects the stair lip from wear. Each tread is about 9.5 inches wide by 30 inches long and 1.2 inches thick (great for covering most step sizes). They add safety for kids, pets, and older adults, reduce noise, and protect your beautiful wood stairs from scratches. This is a 2-piece pack. They're washable and come in gray (and other colors). Just make sure your stairs are clean and dry before you place them. An easy, renter-friendly way to make your home safer and cozier.
