Abstract: Process for producing flexible polyurethane foams in particular molded flexible polyurethane foams, by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, wherein the component b) comprises b1a) at least one polyether alcohol having an end block of ethylene oxide units which has been added on by means of DMC catalysis and makes up not more than 10% by weight of the weight of the alkylene oxide added on by means of DMC catalysis, and/or b1b) at least one polyether alcohol comprising a terminal mixture of ethylene oxide and propylene oxide which has been added on by means of DMC catalysis and has an ethylene oxide content in the mixture of at least 25% by weight, and also b2a) at least one polyether alcohol or comprising exclusively propylene oxide units, and/or b2b) at least one graft polyether alcohol.
