1. A supportive, non-slip carpet underlay comprising:
a multilayered composite material, comprising: (a) a top facing layer composed of a first and second stratum of unsupported polymeric foam, wherein the second stratum has greater cubic density than the cubic density of the first stratum; (b) an intermediate fabric carrier composed from entangled synthetic or recycled needle-punched filaments, wherein the subjacent surface of the second stratum of unsupported polymeric foam is bonded to the uppermost surface of the fabric carrier with an interjoining layer of adhesive; and (c) a base layer of non-slip polymeric resin disposed upon the lowermost surface of the intermediate fabric carrier.
