SEAT PAD

Abstract: a seat pad includes a polyurethane foam, and the polyurethane foam has a compressive residual strain �of 5.0% or less and a wet heat compressive residual strain �of 5.0% or less. the “compressive residual strain �” refers to a value (temperature: 70� c., compression rate: 50%) as measured in accordance with jis k 6400-4, and the “wet heat compressive residual strain �” refers to a value (temperature: 50� c., humidity: 95% rh, compression rate: 50%) as measured in accordance with jis k 6400-4. the polyurethane foam preferably has a 25% hardness of 150 n or more.
