The present disclosure relates to cushioning members, methods of making and methods of using, particularly to cushioning members comprising a plurality of spaced apart pillars comprising a polymeric material.
1 . A cushioning member, comprising:
a multilayer material comprising a barrier layer, a polymeric material layer disposed adjacent to the barrier layer, and a stabilization layer disposed adjacent to and opposite the barrier layer;
a plurality of pillars disposed in the multilayer material, each of the plurality of pillars comprising an upper surface and a sidewall extending downwardly from the upper surface to define a radiused upper edge disposed between the upper surface and the sidewall;
a plurality of spacer regions disposed between the plurality of pillars, each of the plurality of spacer regions comprising a spacer region width;
wherein each of the plurality of pillars comprises a height and a base width, and the ratio of the pillar height to the pillar base width is about 0.125:1 to about 8:1.
2 . The cushioning member of claim 1 , wherein the plurality of pillars have a thickness of less than about 3 inches, and the plurality of spacer regions have a thickness of about 0.005″.
3 . The cushioning member of claim 1 , wherein the plurality of pillars have a thickness of less than about 3 inches, and the plurality of spacer regions have a thickness of about 0.250″.
4 . The cushioning member of claim 1 , wherein the barrier layer is selected from the group consisting of textiles, textile composites, thermoplastic elastomer (TPE) materials, and combinations comprising at least one of the foregoing.
5 . The cushioning member of claim 4 , wherein the barrier layer is a thermoplastic polyurethane (TPU).
6 . The cushioning member of claim 1 , wherein the barrier layer comprises an elongation of at least about 100 percent.
7 . The cushioning member of claim 1 , wherein the barrier layer has a thickness of less than or equal to about 5 mil.
8 . The cushioning member of claim 1 , wherein the barrier layer has a thickness of greater than or equal to about 5 mil.
9 . The cushioning member of claim 1 , wherein the barrier layer comprises a moisture transmittable material.
10 . The cushioning member of claim 1 , wherein the barrier layer comprises a phase changing material.
