It is highly recommended to have an underlay pad for every rug. An underlay will make the rug last much longer by diffusing the wear of footsteps. Our thickest pad will really quiet a loud wood floor and also insulate from a cold stone floor. With rugs under 8×10 there is a sliding risk if there is no underlay to grip the floor. Lastly, a nice pad with make the rug feel softer and more luxurious to walk on. We are happy to give you a quote to cut a pad to your rugs specific size.
