Abstract
A cushion construction method is provided whereby a resilient polymeric foam core is covered with an intermediate flexible non-woven fabric which is adhered to the foam by mechanical force with the ends of the intermediate fabric urged into slits formed in the polymeric core. A conventional decorative outer fabric is sewed or otherwise attached over the intermediate fabric to complete the cushion construction. The completed cushion is lightweight and requires no adhesives or solvents in its method of manufacture.

A method of forming a furniture cushion comprising the steps of:
- (a) forming a resilient core;
- (b) providing a slit in said core;
- (c) covering the core with an intermediate non-woven flexible material layer having a thickness from approximately 10% to 125% of the core thickness;
- (d) inserting an end of the intermediate non-woven flexible material layer into the core slit;
- (e) covering the core and intermediate non-woven flexible materials layer assembly with an outer layer.

A method of forming a cushion comprising the steps of:
- (a) cutting resilient polymeric foam block to form a core;
- (b) slitting the sides of the core to receive ends of an intermediate non-woven flexible material layer having a thickness from approximately 10% to 125% of the core thickness;
- (c) covering the core with the intermediate non-woven flexible material layer;
- (d) inserting the ends of the intermediate non-woven flexible material layer into the slit sides of the core to maintain the intermediate non-woven flexible material layer on the core;
- (e) covering the core and intermediate non-woven flexible material layer assembly with an outer layer.
