Claims (1)

[Claims for Utility Model Registration] (1) Consisting of a plurality of bags connected to an air intake/exhaust sequential switching means connected to an air compressor, wherein one of the plurality of bags is connected to an air intake/exhaust sequential switching means connected to an air compressor. First, the first bag in the direction of the user's feet inflates, and then when the second bag in the shoulder and neck direction begins to inflate, the air in the first bag starts to escape. In a futon with a built-in wavy pine surge device that operates in one direction or in reciprocating motion, the volume of the bag body at a location corresponding to the midway between the waist and back where a gap occurs between the surface of the futon and the back when the user lies on his or her back. is the same as other bags, but the length of the bag in the longitudinal direction is shorter than other bags.
A futon with a built-in wavy pine surge device, characterized in that the length of the bag body in the transverse direction is longer than other bag bodies. (2) The futon has a lower layer having an elastic restoring force made of a flat synthetic resin foam material, and a wavy uneven portion made of a synthetic resin foam material and continuous approximately parallel to the width direction of the cloth body on the upper surface, and It consists of a three-layer structure in which a middle layer has resistance to compressive loads, and an upper layer made of a synthetic resin foam material and has many protrusions on the top surface and has an elastic restoring force. 2. The futon with a built-in wavy pine serge device according to claim 1, wherein a wavy pine surge device comprising a plurality of bags for performing wavy pine surge is housed in the space between the lower surfaces. (3) Depth from the top surface of the futon at the concave part of the wavy unevenness on the top surface of the middle layer of the three-layer structure, which corresponds to the middle part between the waist and the back when the user lies on the futon made of the three-layer structure. 3. The futon with a built-in wavy pine surge device according to claim 2, wherein the depth of the recess from the top of the futon to the other recesses on the top of the middle layer is shallower. (4) In the concave part of the wavy uneven part on the upper surface of the middle layer of the three-layer structure, which corresponds to the middle part of the waist and back when the user lies on the futon made of the three-layer structure, 3. The futon with a built-in wavy pine surge device according to claim 2, wherein a synthetic resin foam material having a contoured curved surface is positioned in the recessed portion of the upper surface of the middle layer.
