A flexible, latex-like polyurethane foam having the "feel" and comfort of a latex foam and an Indentation Force Deflection (25% IFD as low as 3 lbs.) and the method of making such foam by reacting a mixture of triol polyether polyols, namely, a) a major proportion of a triol polyol having a hydroxyl

A flexible, latex-like polyurethane foam having the "feel" and comfort of a latex foam and an Indentation Force Deflection (25% IFD as low as 3 lbs.) and the method of making such foam by reacting a mixture of triol polyether polyols, namely, a) a major proportion of a triol polyol having a hydroxyl content of about 50-80%, a 10-25% ethylene oxide cap and a molecular weight of about 3,000-6,500, (b) a minor proportion of a polymer triol polyol, preferably SAN polyol, having a molecular weight of about 3,000-6,5000; and (c) a very minor amount of a triol polyol having a primary hydroxyl content of at least 50% and about 40-90% ethylene oxide cap and a molecular weight of from 1,000-6,000. The polyol mixture is reacted with a MDI isocyanate in the presence of a critical amount of from about 1.5 to about 3.5 parts by weight of water, an auxiliary blowing agent and an amine catalyst. The IFD or stiffness value of the foam is increased by decreasing the amount of auxiliary blowing agent used and the resulting latex-like foam still maintains the "feel" and comfort of a latex foam.
