    Abstract: A high-resiliency polyurethane foam comprises the reaction product of an isocyanate and an isocyanate-reactive component. The isocyanate-reactive component comprises a first polyether polyol in an amount of greater than about 5 parts by weight and a second polyether polyol in an amount of less than about 80 parts by weight, with parts by weight based on the total weight of the isocyanate-reactive component. The high-resiliency polyurethane foam has a resilience of about 45 to about 70% when tested in accordance with ASTM D3574-11. A method of forming a high-resiliency polyurethane foam includes the steps of providing the isocyanate and the isocyanate-reactive component and reacting the isocyanate and the isocyanate-reactive component.
