Abstract: The present invention is a bottom surface layer for a floor covering which includes a base and a top surface layer. The bottom surface layer includes a flat member having a first surface and a second surface. The first surface is mechanically coupled to the base of the floor covering. The bottom surface layer also includes a plurality of bristles which are electrostaticly flocked onto the second second surface of the flat member and permanently bonded thereto whereby the plurality of bristles lock into a carpet on a floor and prevent lateral sliding of the floor covering when the feet of a sitting person produce downward and lateral forces on the floor covering. The flat member may be formed out of compounded tire rubber and the top surface layer has a raised design for collecting dirt and providing drainage. The flat member may also be formed out of a fabric material which is fixedly coupled to the base of the floor covering.

The bottom surface layer includes a flat member having a first surface and a second surface. The first surface is mechanically coupled to the base of the floor covering. The bottom surface layer also includes a plurality of nylon bristles which are electrostatically flocked onto the second surface of the flat member and permanently bonded thereto whereby the plurality of nylon bristles lock into a carpet on a floor and prevent lateral sliding of the floor covering when the feet of a sitting person produce downward and lateral forces on the floor covering. The flat member may be formed out of compounded tire rubber and the top surface layer has a raised design for collecting dirt and providing drainage.
