摘要： Provided is a polyurethane foam in which cushioning properties are not easily impaired at a low temperature. The polyurethane foam is a polyurethane foam obtained from a composition containing a polyol and a polyisocyanate, and when a 25% compression load measured under a condition of 25° C. is P1 (MPa) and a 25% compression load measured under a condition of −30° C. is P2 (MPa), (P2/P1)×100≤180 is satisfied.
