Polyurethane foams are formed as the reaction product of a polyol selected from a fatty acid, a glycol, a mineral oil, a carbohydrate, or a combination thereof with a polyisocyanate in the presence of a catalyst and at least one blowing agent. Also, polyurethane foams are formed as the reaction product of a polyol selected from a vegetable oil, a mineral oil, a glycol, a syrup, or a combination thereof with a polyisocyanate in the presence of a catalyst and at least one blowing agent. A method for producing polyurethane foam compositions is directed to producing a polyol blend comprising a fatty acid, a glycol, a mineral oil, a carbohydrate, or a combination thereof, and reacting the polyol blend with a polyisocyanate blend in the presence of a catalyst and a blowing agent. Also, a method for producing polyurethane foam compositions is directed to producing a polyol blend comprising a vegetable oil, a mineral oil, a glycol, a syrup, or a combination thereof, and reacting the polyol blend with a polyisocyanate blend in the presence of a catalyst and a blowing agent.
