PROBLEM TO BE SOLVED: To provide a polyurethane foam containing a biological polyol and a cross-linking agent. SOLUTION: This polyurethane foam comprises a reaction product prepared by reacting at least one polyisocyanate with a polymer polyol (PMPO), a vegetable oil hydroxylate in an amount of at least about 25 wt.% based on the weight of the polyol component, an aliphatic polyhydroxyalcohol having a functional value of about 3 to about 8 and a mol.wt. of about 350 in an amount of about 0 to about 3 wt.% based on the weight of the polyol component, and, if necessary, a polyol component containing a non-vegetable oil-based polyol, if necessary, in the presence of at least one of a foaming agent, a surfactant, other cross-linking agents, an extender, a pigment, a flame retardant, a catalyst and a filler.
