ていた。 However, when the synthetic resin foam is used alone, there is a drawback that the cushion material slumps significantly, giving a feeling of bottoming out, and also sagging. In order to eliminate these drawbacks, we can attach a tensile fabric to the surface of the synthetic resin foam,
Strength was increased by attaching a high-density foam sheet with high density and strong tensile and compressive forces as a reinforcing material.

上皮部分または下皮部分は、緻密なスキン部分７
とフオーム部分６とから構成される。 The block epithelium or block hypodermis formed during the production of a soft urethane foam block is a dense skin-like portion formed on the upper and lower surfaces of the slab block when the urethane foam slab block is foamed. The material left over from cutting out the slab can be used. Therefore, the epithelial part or hypodermal part used in the present invention is the dense skin part 7.

ものである。 The cushion core material for pine tresses of the present invention is as described above.The skin foam sheet that is attached to the surface of the synthetic resin foam that has cushioning properties has high density, hardness, and tensile strength. The core material of the cushion has increased hardness, and even when a load is applied, it does not slump easily, does not feel bottomed out, and has an excellent tension effect. When using the cushion core material of the present invention as a pine tress, the first
As shown in the figure, when used on the lumbar region of a person lying on a pinerest, it prevents the lumbar region, which bears the most weight, from sinking, maintains a normal posture, and is good for health.

時の感触に優れたものである。 In addition, since the epidermal foam sheet of the present invention uses the epithelial or hypodermal portion of the foam block containing a high-density skin portion, the original thickness of the foam sheet with the same density is smaller than that of a foam sheet in which only the foam is compressed. The material cost is extremely low because it uses parts that are normally processed as scrap.
Furthermore, in this invention, the dense skin side of the skin foam sheet is attached to the synthetic resin foam cushion material, so the adhesive bond between the two is strong and durable. The surface of the material has a softer foam part attached to the dense skin part, giving it an excellent feel when in use.
