Abstract
A cushion includes a cushioning element and a coating material provided on a surface of the cushioning element. The cushioning element includes an elastomeric material forming a plurality of intersecting buckling walls defining a plurality of hollow columns in an expanded form. The coating material includes stearic acid, a metal stearate, propylene glycol, and triethanolamine. The cushioning element is configured to be compressed, such as by a roll-packing machine, into the compressed form and subsequently released from the compressed form to transform to the expanded form. Methods of forming the cushion include forming the cushioning element comprising an elastomeric material, coating a surface of the cushioning element with the coating material, and compressing the cushioning element into a compressed form.
