ABSTRACT:
A body from resilient foam material is furnished, such as a buffer, a seat cushion or a mattress formed from foam rubber or synthetic foam material, which has been provided with a plurality of slits (3), with which spring elements (3) are enclosed in a tight fitting arrangement, which in loaded condition are in contact with the two walls of the slit and cannot shift with respect to the slit walls. The spring elements in unloaded condition are substantially free of tension and have a spring characteristic equal to or hardly different from the characteristic of the foam material. The normal decrease in rigidity of the resilient foam bodies of this type has been completely obviated such that cheaper foam materials can be used, in particular those which therewith also have a greater softness.
