To provide a composition for a flexible polyurethane foam, capable of producing a flexible polyurethane foam with reduced odor and also excellent curability.SOLUTION: The composition for a flexible polyurethane foam contains a polyether polyol (A), a reactive amine catalyst (B) having one or more amino groups and one or more hydroxyl groups, a non-reactive amine catalyst (C) having one or more amino groups and having no hydroxyl group, and a silicone foam stabilizer (D). The content of the reactive amine catalyst (B) is 0.01-1.3 pts.mass, the content of the non-reactive amine catalyst (C) is 0.01-0.20 pt.mass, and the content of the silicone foam stabilizer (D) is 0.2-1.5 pts.mass based on 100 pts.mass of the total of polyol components having no amino group. The silicone foam stabilizer (D) contains two kinds of silicones (D1 and D2) having different surface tensions.SELECTED DRAWING: None
