Cushion Filling cushions and pads are filled with heat-bonded, vertically-layered polyester fiber filling. The fibers are vertically layered and heat-bonded to create sheets of firm 100% polyester fibers that stand upright and support each other for maximum product life. The heat-bonding process uses heat to bond the polyester fibers together forming sheets of filling that are custom-cut and shaped to fit your cushions perfectly.

NOTE: does NOT use resin-bonded fibers which are often bonded using flamable resins that break down and cause cushions to become dusty.
