Abstract
The invention describes a foamed material panel, in particular a shaped part composed of one or several foamed material panels. These panels consist of a soft and, if appropriate, elastic foamed material comprising cellular webs and/or cellular walls that are permanently deformed at least in some areas. A central area of the foamed material panel is plastically deformed to a higher volumetric weight than at least one intermediate area of the formed material panel.
