25. A method of making a composite structure for use as resilient cushion comprising:
-
(a) providing a sheet of resilient material having opposing sides; (b) applying an adhesive to either or both sides of the sheet of resilient material; (c) providing a cutter having a surface and a plurality of cutting elements extending from the surface in a predetermined pattern; (d) pressing the cutter into the sheet of resilient material, thereby forming a cut sheet of resilient material comprising a plurality of resilient elements and excess resilient material; (e) withdrawing the cutter from the cut sheet of resilient material; (f) removing adhesive layer from the excess resilient material on the first side of the cut sheet of resilient material, leaving adhesive layer on the resilient elements; (g) bonding a first fabric or mesh substrate to the first side of the cut sheet of resilient material resulting in bonding between the resilient elements to the first substrate; and (h) separating the excess resilient material from the cut sheet of resilient material, leaving the plurality of resilient elements bound to the first substrate. - View Dependent Claims (26, 27, 28, 31)

29. A method of making a composite structure for use as resilient cushion comprising:
-
(a) providing a sheet of resilient material having opposing sides; (b) applying an adhesive to either or both sides of the sheet of resilient material; (c) providing a cutter having a surface and a plurality of cutting elements extending from the surface in a predetermined pattern; (d) pressing the cutter into the sheet of resilient material, thereby forming a cut sheet of resilient material comprising a plurality of resilient elements and excess resilient material; (e) withdrawing the cutter from the cut sheet of resilient material; (f) covering the excess resilient material with a blocking sheet of a substrate with a pattern so that only the resilient elements are free to bond to any other substrate; (g) bonding a first fabric or mesh substrate to the first side of the cut sheet of resilient material resulting in bonding between the resilient elements to the first substrate; and (h) separating the excess resilient material from the cut sheet of resilient material, leaving the plurality of resilient elements bound to the first substrate.
