PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane foam having low elastic resilience, an open-cell structure of high connection degree of the cells and small temperature dependency of the foam rigidity.SOLUTION: This polyurethane foam is produced by reacting (A) a polyol composition with (B) an organic polyisocyanate in the presence of a catalyst and a foaming agent. The polyol composition (A) is composed of (a) a polyether polyol having two or more functional groups and an OH equivalent of 800-3,000, (b) a polyether polyol having three or more functional groups and an OH equivalent of ≥200 and
