If you have a runner rug on hardwood or carpet, you probably need a runner rug pad.

The right rug padding protects your runner and keeps it from sliding. Rug Expo is the place to go for a custom-cut runner pad. Rug Expo has a large, experienced staff and provides excellent customer service. We'll cut a runner rug pad for you to order, or while you wait.
