To provide a process for producing a flexible polyurethane foam that has excellent moldability with a long cream time, and that has excellent hardness and durability. A process for producing a flexible polyurethane foam, which comprises reacting a polyol mixture (X) with a polyisocyanate compound in the presence of a urethane-forming catalyst, a blowing agent and a foam stabilizer, characterized in that the polyol mixture (X) comprises a polyoxyalkylene polyol (A) having an average of from 2 to 3 hydroxy groups, a number average molecular weight of from 8,500 to 30,000 and an oxyethylene group content of from 0 to 30 mass %, a polyoxyalkylene polyol (B) having an average of from 2 to 3 hydroxy groups, a hydroxy value of from 20 to 250 mgKOH/g and an oxyethylene group content of from 0 to 20 mass %, and a polyoxyalkylene monool (D) having a hydroxy value of from 10 to 200 mgKOH/g.
