Abstract: A three dimensional polymeric fiber matrix layer including a phase change material coated thereon for use in a bedding product such as a mattress is disclosed. The phase change material is selected to provide improved cooling properties, which along with the free volume provided by the three dimensional polymeric fiber matrix markedly improves temperature management when used in a bedding product.

Abstract: A three dimensional polymeric fiber matrix layer for use in a bedding product such as a mattress is disclosed. The three dimensional polymeric fiber matrix layer generally includes a plurality of randomly oriented polylactide (PLA) fibers bonded at coupling points between adjacent PLA fibers and having a free volume per unit area of the layer.

Abstract: A layer for a bedding product such as a mattress includes an extruded three dimensional polymeric fiber matrix layer having constant length, width and height dimensions, the extruded three dimensional polymeric fiber matrix layer comprising randomly oriented fibers bonded at coupling points between adjacent fibers and having a free volume per unit area of the layer, wherein the fibers comprise a polymer and a phase change material.

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.
