A method for producing a polyurethane flexible foam, which comprises reacting at least one high molecular weight polyol selected from the group consisting of a polyoxyalkylene polyol having a hydroxyl value of from 5 to 38 mgKOH/g, from 2 to 8 hydroxyl groups and a total unsaturation degree of not more than 0.07 meq/g and a polymer-dispersed polyol containing said polyoxyalkylene polyol as the matrix, an optional crosslinking agent and a polyisocyanate compound in the presence of a low viscosity compound having an addition-polymerizable unsaturated group, a catalyst, a foaming agent and a foam stabilizer.
