    Abstract: PROBLEM TO BE SOLVED: To provide a yellowing-resistant soft polyurethane foam having highly suppressed yellowing of the foam and resulting migration and discoloration by using a conventional versatile polyol component without using expensive aliphatic isocyanate as the isocyanate. SOLUTION: The invention provides a yellowing-resistant soft polyurethane foam obtained by foaming a polyurethane raw material containing a polyol component and an isocyanate, wherein the polyurethane raw material further contains urea. More excellent discoloration preventing effect is attained by using a polyether polyol having an ester bond in the polyol skeleton and containing a plurality of benzene rings in the polyol structure as the polyol component.
