The invention relates to a polyurethane foam-forming composition, a seat foam made from the composition and a method of making the same, and a seat comprising the seat foam. The composition for forming a polyurethane foam includes a polyol mixture including two or more polyols having different melting points, in which the two or more polyols are respectively included in the same weight ratio, an isocyanate compound, and a blowing agent. A foam for a vehicle seat includes a polyurethane foam made from the composition for forming a polyurethane foam as described above. A method of manufacturing a foam for a vehicle seat includes manufacturing a polyurethane foam from the composition for forming the polyurethane foam as described above, and applying a coating composition comprising 1 wt% to 5 wt% of carbon nanotubes onto at least one surface of the polyurethane foam. A vehicle seat includes a foam for a vehicle seat as described above.
