ABSTRACT:
A sheet material comprising a cushioning layer formed of resilient, cushioning material, and a non-absorbent, thermally non-conductive top layer of thermoplastic material formed with apertures which is embedded into the cushioning layer so that the cushioning material extends at least partially into the apertures in the top layer. The coefficient of friction of the top layer of the sheet material can be varied to alter the degree of slip-resistance of the sheet material depending upon the requirements of a particular application. The cushioning material forming the cushioning layer may be moisture-absorbent to help channel away moisture from the top layer, and, in one embodiment, is affixed to a second cushioning layer to form a three-layer sheet material.
