The present invention provides a method for producing a flexible polyurethane foam in which a polyol premix for producing a polyurethane foam has good aging stability and good moisture resistance. A method for producing a flexible polyurethane foam by reacting an active hydrogen component (A) with an organic polyisocyanate in the presence of a foaming agent comprising water, a urethanizing catalyst, and a foam stabilizer is provided. Is an alkylene oxide adduct of an active hydrogen compound, wherein the content of the internal oxyethylene unit is 0.1 to 15% by mass, and a 1,2-alkylene oxide having 3 or more carbon atoms at the terminal is A method for producing a flexible polyurethane foam, comprising using a polyether polyol (a) which is added and at least 40% of the terminal hydroxyl group-containing groups are primary hydroxyl groups represented by a specific chemical formula.
