The floor mat of the present process is a pliable multilayer structure having an upper face layer and a base layer. The base layer has a main body section bordered by an edge section. Preferably, the main body section is relatively thin and the edge section is relatively thick. A surface of the base layer is adapted to confront flooring overlaid by the mat. The edge section has a channel extending longitudinally thereof, and preferably opening from the bottom surface of the edge section. A portion of the main body section can have a channel molded therein such that a portion of the main body section is disposed above the remainder of the main body section to provide a decorative and aesthetically pleasing design in the main body section.

[ That which is claimed is:] [15.] A method of forming an integral raised portion in a pliable, multi-layer floor mat having an upper face layer overlying a base layer, said method comprising the steps of:molding an integrally molded channel in the floor mat by placing the base layer and the face layer under a compressive molding pressure applied to a bottom surface of the base layer and the top surface of the face layer;embedding a portion of the bottom surface of the face layer in the upper surface of the base layer;heating the base layer to cure the base layer while the face layer and the base layer are under the compressive molding pressure; andmaintaining the heating of the base layer until the base layer is cured, so as to form an integral raised portion in the floor mat, defined by said integrally molded channel;wherein said molding step includes forming a relatively thin main body section bordered by a relatively thick edge section. .Iaddend..Iadd.16. A method according to claim 15 where the face layer is comprised of tufted pile carpeting, said process further comprising the step of crushing the carpet pile while the base layer and the face layer are under compressive molding pressure. .Iaddend..Iadd.17. A method according to claim 15 where the face layer is comprised of tufted pile carpeting, said process further comprising the step of cooling the face layer to maintain the pile carpeting of the face layer below a temperature at which the carpet pile becomes substantially permanently deformed under the applied molding pressure so as to maintain the resiliency of the carpet pile upon release of the compressive molding pressure, the cooling being conducted simultaneously while the face layer and the base layer are under pressure. .Iaddend..Iadd.18.
