Methods and compositions for forming polyurethane foam. A method for manufacturing an aromatic polyester polyol comprises heating a glycol, a dicarboxylic acid or ester, functionality enhancing agent, and a natural oil to about 480° F. to form a reaction product, allowing the reaction product to cool to about 140° F., and adding additional glycol to form an aromatic polyester polyol composition, wherein the total glycol comprises less than about 36 weight percent of the polyol composition. An aromatic polyester polyol composition comprises a glycol, a dicarboxylic acid or ester, functionality enhancing agent, and a natural oil, wherein the total glycol comprises less than about 36 weight percent of the aromatic polyester polyol composition. An aromatic polyester polyol composition comprising a cyclopentane solubility of at least about 25 percent, a hydroxyl number of at least about 150, the natural oil comprising less than about 25 weight percent, and/or the dicarboxylic acid or ester comprising more than about 29 weight percent of the polyol composition.
