Abstract
A shaped element consists of a soft and preferably elastic foamed material, comprising cellular webs which have been deformed remanently at least over areas. The shaped element is formed from a foamed material granulate, a soft foamed material having a grain size of 2 to 20 mms and filler material, for example cork granulate, rubber granulate, chalk, calcium carbonate, hard polyurethane scraps or thermoplastic plastics material scraps, with a grain size of 2 to 20 mms, which are distributed in the soft foamed material by the foaming action. The cellular webs or walls between the individual floccules of the foamed material granulate and/or of the filler material are remanently deformed over the areas concerned.
