Process for producing polyurethane foam using as a foam stabilizer an organosilicone oil and a hydrocarbon oil
 A process for producing high resilience polyurethane foam utilizing as a foam stabilizer a combination of an organosilicone oil of average molecular weight 200-2000 composed of the blocks represented by the formula ##EQU1## (where a+b is 1 to 3, b is 0 or 1, R is methyl group, and R' is a hydrocarbon group of 3-15 carbon atoms) and a hydrocarbon oil of average molecular weight 200-2000 containing more than 20 wt. % of alicyclic hydrocarbon and/or aromatic hydrocarbon.
