What is the difference between your Felt + Rubber rug pads?

Both of our Felt + Rubber rug pads are Dual Purpose pads, designed to offer high levels of both cushioning and grip. Superior lock is thicker than contour lock, thus offering more cushion if your looking to maximize comfort. Superior Lock also has a textured reinforced backing that offers slightly more grip than Contour Lock. Therefore, go with Contour Lock if you for a more flush look with moderate cushioning and Superior Lock if your looking to really maximize cushion.
