Pre-conditioned three dimensional polymeric fiber matrix layer for bedding products

Abstract

A pre-conditioned three dimensionally polymeric fiber matrix layer for use in a bedding product such as a mattress is disclosed. The pre-conditioned three dimensionally polymeric fiber matrix layer generally includes an extruded three dimensional polymeric fibrous layer and a foam material, e.g., polyurethane, latex or the like, disposed within the fibrous layer and occupying at least a portion of the free volume in the layer, wherein a portion of the coupling points and the randomly oriented polymer fibers are broken so as to change a mechanical property of the pre-conditioned three dimensionally polymeric fiber matrix layer relative to the three dimensionally polymeric fiber matrix layer without pre-conditioning.
