A cushion includes a cushioning element and a coating provided on a surface of the cushioning element. The cushioning element comprises an elastomeric material forming a plurality of intersecting buckling walls defining a plurality of hollow columns in an expanded form. The elastomeric material comprises an elastomeric polymer and a plasticizer. The coating comprising an olefin powder formulated to hinder adhesion of the elastomeric material when the cushioning element is in a compressed form such that the plurality of intersecting buckling walls is pressed together. The cushioning element is configured to be compressed 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 olefin powder, and compressing the cushioning element into a compressed form.
