When ordering a custom foam cushion for a sofa, customers may have a choice between ordering the foam interior of the cushion or replacing its cloth, leather and other outer material. Plain foam filling is typically less expensive than other materials and works well when a sofa cushion just needs a replacement filling. Back cushions are usually filled with polyester stuffing instead of solid foam.
