Examples of the three-dimensional knitted fabric include a three-dimensional mesh structure and a double raschel structure. Examples of the three-dimensional structure fabric include three-dimensional multilayer structure fabric.

The first layer 4 of this embodiment is integrally formed of a three-dimensional network structure. The three-dimensional network structure is, for example, a structure formed of resin wires irregularly intertwined in a three-dimensional shape. The first layer 4 is formed, for example, by extrusion molding a resin wire that constitutes a three-dimensional network structure into a flat plate shape. The first layer 4 is desirably formed into a single plate-like shape as a whole when cooling the extruded resin wire in a three-dimensionally irregularly intertwined state.

The first layer 4 has excellent breathability and appropriate flexibility, and can hold the lying user P while suppressing the generation of heat between the first layer 4 and the user P.

The first thickness t1 of the first layer 4 is preferably 10 to 25 mm. Since the first thickness t1 of the first layer 4 is 10 mm or more, generation of heat between the first layer 4 and the user P can be reliably suppressed. Since the first thickness t1 of the first layer 4 is 25 mm or less, it is possible to prevent the mattress 1 from becoming excessively large.

The second layer 5 includes a first base surface 5a extending parallel to the first surface 2a of the top surface 2, a second base surface 5b extending parallel to the second surface 2b of the top surface 2, and a second base surface 5b extending parallel to the second surface 2b of the top surface 2. The third base surface 5c extends parallel to the third surface 2c. Such a second layer 5 serves to define the shape of the upper surface 2 of the mattress 1 in its natural state.

The second layer 5 is made of, for example, a resin material with excellent flexibility and restorability. The second layer 5 of this embodiment is made of urethane foam. Such a second layer 5 serves to define the angles of the first base surface 5a, the second base surface 5b, and the third base surface 5c. The second layer 5 is not limited to such materials, and may be formed of, for example, synthetic cotton such as polyester resin cotton, natural cotton such as cotton, or the like.

The second layer 5 is composed of a plurality of divided pieces 7, which are divided into three in this embodiment, in the first direction D. Such second layer 5 can be folded compactly. Note that the second layer 5 is not limited to such a mode, and may be configured integrally in the first direction D, for example. The second layer 5 in this case may have a structure in which, for example, a slit extending from the lower surface 3 toward the upper surface 2 is provided at the folding position so that it can be easily folded.

FIG. 3 is a perspective view of the second layer 5. As shown in FIGS. 2 and 3, the divided pieces 7 of the second layer 5 include, for example, a first divided piece 7a on the side of the head Pa, a second divided piece 7b in the center in the first direction D, and an ankle part. A third divided piece 7c on the side of part Pb is included. Such a second layer 5 is suitable for being folded into a four-fold state. Note that the divided pieces 7 are not limited to such an aspect; for example, the second layer 5 may be divided only at the central portion 1C to be composed of two divided pieces 7 as a whole; The two-part piece 7b may be divided at the center portion 1C to be composed of four divided pieces 7 as a whole.

The length L4 of the first divided piece 7a in the first direction D is preferably 20% to 30%, more preferably 25% of the total length La of the upper surface 2 in the first direction D. The length L5 of the second divided piece 7b in the first direction D is preferably 45% to 55%, more preferably 50% of the total length La of the upper surface 2 in the first direction D. The length L6 of the third divided piece 7c in the first direction D is preferably 20% to 30%, more preferably 25% of the total length La of the upper surface 2 in the first direction D.

FIG. 4 is a side view of the mattress 1 in a folded state. As shown in FIG. 4, the mattress 1 of this embodiment can be folded into four by folding the second divided piece 7b at the central portion 1C. Such a mattress 1 can be compactly folded to about 25% of the total length La of the upper surface 2 in the first direction D.

As shown in FIG. 3, the first divided piece 7a of this embodiment defines a part of the first base surface 5a. The second divided piece 7b defines, for example, the remainder of the first base surface 5a, the entire second base surface 5b, and a part of the third base surface 5c. It is desirable that the third divided piece 7c defines the remainder of the third base surface 5c. In such a second layer 5, the shapes and division positions of the first base surface 5a, second base surface 5b, and third base surface 5c can be independently set arbitrarily, and the comfort of the user P is improved. It is possible to achieve both compactness and compactness when folded.

As shown in FIG. 2, the cover 6 includes, for example, an inner cover 6A that covers the first layer 4 and the second layer 5, and an outer cover (not shown) that removably covers the entire inner cover 6A. There is. Such a cover 6 can be washed by removing the outer cover, thereby improving the comfort of the user P.

The outer cover is made of, for example, a breathable cloth material. The outer cover is preferably formed by three-dimensionally sewing a non-stretchable cloth material. Such an outer cover can define the shape of the upper surface 2 in cooperation with the inner cover 6A.

FIG. 5 is a partial sectional view of the inner cover 6A. As shown in FIGS. 2 and 5, the inner cover 6A of this embodiment includes a first portion 6a that covers the first layer 4 and a second portion 6b that covers the second layer 5. As shown in FIGS. The inner cover 6A includes, for example, a plurality of second portions 6b below one first portion 6a. Such an inner cover 6A can hold the first layer 4 and the second layer 5 independently, and can suppress displacement of each layer.

The first portion 6a of the inner cover 6A of this embodiment has an internal space having the same shape as the first layer 4 when formed as the mattress 1. That is, the first portion 6a is desirably sewn in three dimensions so that the shape of the side surface 6c of the first portion 6a is the same as the cross-sectional shape of the first layer 4 in the cross-sectional view shown in FIG. The first portion 6a is, for example, three-dimensionally sewn with the first layer 4 inside. Such an inner cover 6A can be configured integrally with the first layer 4. In addition, the 1st part 6a may hold the 1st layer 4 so that it can be put in and taken out, for example.

The plurality of second portions 6b of the inner cover 6A of this embodiment each have an internal space having the same shape as the divided piece 7 of the second layer 5. That is, the second portion 6b is desirably sewn in three dimensions so that the shape of the side surface 6d of the second portion 6b is the same as the cross-sectional shape of the divided piece 7 in the cross-sectional view shown in FIG. The second portion 6b is, for example, three-dimensionally sewn with the divided piece 7 of the second layer 5 inside. Such an inner cover 6A can be configured integrally with the second layer 5, and in its natural state, the flat first layer 4 is connected to the first base surface 5a, the second base surface 5b, and the second base surface 5a of the second layer 5. It can be held along the third base surface 5c.

For this reason, the inner cover 6A of this embodiment has a flat plate shape that follows the natural state of the first layer 4 when only the first layer 4 is placed inside, but the second layer 5 cannot be placed inside. Thus, the shape of the mattress 1 can be maintained in its natural state. Such an inner cover 6A is unlikely to wrinkle or twist between itself and the outer cover, improving comfort, preventing breakage, and improving durability. In addition, the 2nd part 6b may hold the 2nd layer 5 so that it can be put in and taken out, for example. Further, when the second layer 5 is integrally formed, the second portion 6b has, for example, a structure having one internal space.

The inner cover 6A includes, for example, a gap portion 6e between the second portion 6b in which each divided piece 7 is placed. Such an inner cover 6A can be easily folded at the gap portion 6e even when the first layer 4 is made of a non-stretchable cloth material that can maintain its shape along the second layer 5. be.

For example, a connecting member (not shown) may be provided in the gap portion 6e of the inner cover 6A. Examples of the connecting member include a fastener, a hook-and-loop fastener, a button, a hook, and the like. Such an inner cover 6A can stabilize the shape of the lower surface 3 and improve comfort during sleeping.

The inner cover 6A is made of, for example, a cloth material that has higher air permeability than the outer cover. Like the outer cover, the inner cover 6A is preferably formed by three-dimensionally sewing a non-stretchable cloth material. The inner cover 6A is formed of, for example, a three-dimensional mesh structure of polyester. Such an inner cover 6A can achieve both high air permeability and shape retention of the upper surface 2.
