ABSTRACT The invention relates to a body of resilient foam material, such as a buffer, a seat cushion or a mattress of foam rubber or synthetic foam material, which body has been provided with a plurality of slits within which tight fitting spring elements are enclosed, 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 differ- ent from the characteristic of the foam material. The normal decrease in rigidity of resilient foam bodies is thus completely obviated so that cheaper foam materials can be used, in particular those which also have a greater softness.
