Rug pads are great because they prevent slippage, prolong wear, protect the floor underneath, and provide additional comfort and quiet. That being said, most of our rugs do not actually require a pad underneath. Many, like those from the Andes, crafted with sheep wool and cotton, are durable and sturdy enough to be placed directly on the floor. But for enhanced protection and longevity, a rug pad is always a welcome addition.
