This rug pad is designed to keep area rugs in place while helping protect hardwood, tile, and other floor surfaces from scratches and wear. Its dual-surface construction combines a polyester felt top with a TPR backing for cushioning, grip, and added stability. The 3 mm thickness provides light comfort underfoot and helps absorb everyday impact. It is waterproof on the backing side and can be trimmed for a more customized fit. Ideal for use under area rugs in living spaces, workout areas, and high-traffic rooms.
