ABSTRACT:
Resilient articles, such as, mattresses and cushions of varying yield resistance to accommodate the weight variation of the body and/or to provide edge support are produced by tailoring tensile forces within the article. Tensile force variation may be accomplished in articles of uniform density by slotting to separate adjacent regions in at least one direction. Tailoring is accomplished by variation in slot depth and/or spacing.
