Further, the width can be a size corresponding to a general single, double, or the like.

  The material which comprises the multifunctional mattress of this invention is not specifically limited, The material used for a well-known mattress can be used. The cushion material is a random three-dimensional loop of continuous filaments of flexible polyurethane foam, rubber foam, and thermoplastic elastic resin. 9-1708 gazette disclosure; commercially available product Breath Air (Toyobo Co., Ltd.) and the like are exemplified, and can be used alone or in combination of two or more. When the cushion material has a multilayer structure, a hard cotton equivalent material may be used as the lower layer member. The skin material of the mattress of the present invention may be a leather, a woven fabric, a non-woven fabric, or the like, which is formed of a known material as a skin material constituting material of the mattress or cushion material.

  FIG. 1 is a perspective view illustrating a preferred form of a multifunctional mattress according to the present invention. FIG. 1 (a) is a state where it can be used as a flat mattress, and FIG. It is in the state folded into three. The mattress 10 is a rectangular flat rectangular parallelepiped in a top view, and includes a first mattress block 12a, a second mattress block 12b, and a third mattress block 12c having the same shape, and each mattress block covers a cushion material and the mattress block. It is composed of a skin material. The first mattress block 12a and the second mattress block 12b, and the second mattress block 12b and the third mattress block 12c are connected to each other on opposite surfaces in a flat state, and are folded at this connecting portion. Can be folded as shown in FIG. The first mattress block 12a and the second mattress block 12b of the mattress 10 include a frame portion 18 and an inner member 14 that is detachably formed on the frame portion 18.

  When the mattress block is configured to be detachable, the connecting method is not particularly limited, and a method of disposing a fastener on the edge of the connecting rectangular parallelepiped, the width direction at the ends of the surfaces contacting each other when folded and folded And a method of disposing a plurality of belt-shaped surface fasteners in the length direction of the mattress in the vicinity of the ends of the surfaces that contact each other when folded and folded. The same configuration can be adopted when the sub-blocks constituting the inner member are detachably connected. The method of detachably attaching the inner member to the frame portion may be a method of simply fitting, or a method of using a fastener or a hook-and-loop fastener.

  The inner member 14 has a configuration corresponding to a case in which the central portions of the first mattress block 12a and the second mattress block 12b connected to each other are cut out to form separate members. That is, the inner member 14 is a rectangular flat rectangular parallelepiped in a top view, and includes a first sub-block 16a and a second sub-block 16b. The first sub-block 16a and the second sub-block 16b are end portions. It is connected so that it can be folded at the section. The inner member 14 may have a shape different from that of the first mattress block 12a, but is preferably the same shape. The first sub-block 16a and the second sub-block 16b may have different shapes, but preferably have the same shape.

  FIG. 2 is an arrangement example in which the multifunction mattress 10 shown in FIG. 1 can be used as a sofa.
