る。1 is a polyurethane foam sheet having a corrugated surface. The thickness of the sheet 1 is, for example, 40 mm. On the polyurethane foam sheet 1, a polyurethane resin impregnated cured layer 2 having a thickness (T) of, for example, 3 mm is formed in a corrugated form. On this hardened layer 2, a latex foam sheet 3 is formed. The cushion body 4 having such a configuration is manufactured as follows.

(2) Next, an undiluted solution obtained by adding an additive such as a tin catalyst and silicone oil to the urethane prepolymer and mixing and stirring the mixture was mixed with the sheet 1 described above.
Is applied to the corrugated surface by, for example, a transfer method, compressed and impregnated through rolls, and then cross-linked and cured through a steam layer to form a polyurethane resin impregnated and cured layer 2. (3) Next, additives such as a vulcanizing agent and a stabilizer are added to, for example, natural rubber latex, and the mixture is mechanically foamed with a foaming stirrer. Then, the sheet 3 is sheeted on a corrugated surface to a predetermined thickness, heated, gelled and vulcanized to form a sheet 3, and a cushion body 4 is obtained.

As shown in FIG. 1, a polyurethane foam sheet 1 having a corrugated surface shape, a polyurethane resin impregnated cured layer 2 having a thickness of 3 mm and a latex foam sheet sequentially formed on the sheet 1 are shown. 3 has a three-layer structure.
However, the presence of the resin-impregnated cured layer 2 has an advantage of having an appropriate finger pressure effect as compared with the conventional case of a polyurethane foam alone. Further, since the resin-impregnated and cured layer 2 is covered with the latex foam sheet 3, the body feels very good without causing any discomfort to the body. Further, the resin impregnated cured layer 2 does not peel off from the sheet 1.
