The primary function of a rug pad is to help reduce wear in heavy traffic areas, but they also provide some level of noise control, add comfort underfoot, and help keep rugs from shifting suddenly. If you need more incentive, TWO of the custom-fit rug pads we carry even offer a pet urine barrier layer to protect your hard-surface floors from becoming damaged from pet accidents. Just ask us to help you decide which pad is best for your rug!
