[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a mattress which can be folded in three.

[0002]

2. Description of the Related Art A normal mattress has a width of 90 cm,
Since the length dimension is about 200 cm, which is very inconvenient for transportation and storage, there is a type in which this long mattress can be folded into three.

A mattress which can be folded into three in this way has first, second and third small mattresses arranged side by side, and an upper edge portion of one side of the first and second small mattresses joined to each other. Are connected by fasteners and the like, and the upper edges of the joined sides of the second and third small mattresses are similarly connected by fasteners and the like, and the first small mattress is folded over the second small mattress. Mattresses in which the third small mattress is folded on the lower surface of the second small mattress have been conventionally developed.

[0004] With the above-mentioned folding mattress, the mattress is folded into three when not in use.
Since the mattress can be stored in a storage body such as a closet, it is very convenient, and there is an advantage that it is very convenient to carry.
