Abstract
A body support comprising at least one layer of flexible material having a reticulated cellular structure is disclosed. In some embodiments, one or more of these layers comprises reticulated visco-elastic foam, and has at least one material property responsive to temperatures in the range of a user's body heat. In these and other embodiments, one or more of the layers of flexible material comprises non-visco-elastic foam, and can be combined in a body support with one or more layers of visco-elastic foam. The body support can include one or more additional layers of other material types, including one or more layers of high-resilience polyurethane foam. Also, in those embodiments having two or more layers of material, one or more of the layers can have a profiled surface at least partially defining air flow paths through the body support.
