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.
