  • Publication number: 20060138811
    Abstract: A cushion has a cushion core, particularly made of a foam material, and an air-permeable and moisture-permeable covering layer that covers the core. To improve the climate comfort by ensuring good removal of moisture from the area between covering layer and cushion core, longitudinal and transverse grooves, spaced apart from one another, are formed in the surface of the cushion core covered by the covering layer. These grooves are open toward the covering layer and intersect one another. In addition, the cushion core is provided with channels which pass through the entire thickness of the core and which, at one end, open out at the points of intersection of the longitudinal and transverse grooves and, at the other end, open freely to the outside of the cushion core.
