Slip-prevention and Shock Absorption The surface of the bed furniture risers is rough and uneven, effectively preventing the overall instability caused by the furniture legs slipping. What's more, the bottom of these bed leg risers is made of TPU slip-prevention rubber, which can adhere tightly and firmly to the floor. While protecting the floor, it won't leave any dents or scratches.
