When should you use a Felt + Rubber rug pad?

A Felt + Rubber rug pad offers the best of both cushioning and grip. Superior Lock is ideal for those looking to maximize cushion with rugs that need grip. Felt and rubber pads also do a fantastic job of promoting rug evenness and preventing bunching that can occur with thinner, lower pile rugs that tend to bunch or knot up easily. The felt surface layer fastens itself to the bottom of your area rug while the natural rubber backing keeps rugs firmly anchored to the floor.
