These carpet stair treads not only protect you from slipping when going up and down stairs, but also keep your stairs from being scuffed. These stair mats are made of 100% PP, making them sound dampening, non-slip and comfortable. The stair-step carpets are also washable. They are folded to protect both the top and the front of the stairs. The two-sided adhesive tapes on the back allow these mats to be attached to the stairs easily and quickly.
