硬さを備えている必要がある。[0003] In such a floor-bed undulating bed, the mattress core used for the bed also bends following the undulation of the bed slab of the bed. Needs to be excellent in flexibility. Furthermore, the mattress core material is required to have cushioning properties. However, if the core material is too soft, the body of the patient sinks and it becomes difficult to turn over, etc., and also the sleeping comfort is poor and the patient may be tired. . For this reason, it is necessary that the mattress core material has cushioning properties and also has an appropriate compression hardness.

であり、７はベッドの床板である。However, in the conventional mattress core material as described above, the curvature radius of the middle core material and the curvature radius of the cushion material when the core material is bent are different from each other. As shown in FIG. 9, among the cushioning materials 3 'and 3' bonded and laminated to the core material 2 ', those outside in the bending direction bend with a larger radius of curvature than the core material 2'.
The force in the direction in which the cushion material 3 'is stretched is concentrated on the portion indicated by the symbol X in the figure, and the texture and cushioning of the cushion material 3' are impaired during repeated bending, and in the worst case, the cushion material is damaged. There is a problem that 3 'is broken. On the other hand, since the cushion material 3 'on the inner side in the bending direction bends with a smaller radius of curvature than the core material, the portion of the cushion material 3' indicated by the symbol Y in the figure is bent at the time of bending, and the surface thereof has more wrinkles. There is also a problem that the unevenness caused by this gives the user a feeling of foreign matter. Especially when raising the patient's upper body by raising and lowering the floorboard, the above irregularities are located just around the patient's waist, and the patient feels the foreign body sensation due to the irregularities sensitively and every time the upper body is raised, the patient feels discomfort Since the cushioning material is forced, it is not preferable that such cushioning bends from the viewpoint of the patient's mental health.
In FIG. 9, reference numeral 6 denotes a surface covering material for covering the surface of the mattress core material, and reference numeral 7 denotes a bed floor plate.

Therefore, both must be separately collected and recycled. Must. However, when the laminating interface between the core material and the cushioning material is firmly bonded with an adhesive, the work of separating the core material and the cushioning material is very troublesome and the separation and collection is not easy. Conventional mattress core materials also have a problem of poor recyclability.
