Abstract: A composite foam article is disclosed herein. The composite foam article comprises a surface layer and abase layer with an interface therebetween. The surface layer comprises a high-resiliency polyurethane foam having an impact resilience of greater than about 50% when tested in accordance with ASTM D3574-17, and presents a seating surface. The base layer comprises a viscoelastic polyurethane foam having an impact resilience of less than about 50% when tested in accordance with ASTM D3574-17, and presents a mounting surface opposite the seating surface. The surface layer and the base layer are present in a thickness ratio of from about 17:3 to about 2:3.
