The coil mattress type futon used here can be used not only as a general futon to be placed on the floor but also as a coil mattress to be placed on a bed.
Any type of coil spring may be used. For example, a pocket coil, a Bonnell coil, or the like may be used.
The number of coil springs used is also not limited.
Moreover, the material of the cover bag is also arbitrary. For example, various cloths, various synthetic resin sheets, and various leathers may be used.

The configuration of the cover bag is also arbitrary. For example, a band-shaped peripheral sheet (peripheral side fabric) is arranged over the entire circumference between the outer edges of the front sheet (front fabric) and the back sheet (lining fabric), and the butted portions are not hemmed, It may be sewn flat. Alternatively, the peripheries of the front sheet and the back sheet may be directly sewn flat without hemming.
Further, the coil mattress may be a laminate having a three-layer structure in which front and back fillings made of cotton, urethane foam, or the like are arranged on the front and back sides of coil springs, respectively, and housed in a rectangular cover bag.

In addition, the mattress (coil mattress) may be divided into a plurality of partial mattresses (partial mattresses) so that it can be folded compactly (for example, a two-fold type, a three-fold type, etc.).
The size of the mattress is arbitrary. Examples include single size, semi-double size, double size, queen size, and king size.

Further, according to the second aspect of the invention, the coil mattress type futon is provided so as to be freely foldable with a plurality of partial futons obtained by dividing the coil mattress type futon. It is a futon.

The split direction of the coil mattress type mattress is arbitrary. For example, it may be in the length direction (front-rear direction) or the width direction (left-right direction) of the mattress.
The number of divisions (the number of partial mattresses used) of the coil mattress type mattress is arbitrary. For example, it may be divided into 2, 3, or 4 or more. Furthermore, this division may be an equal division or an unequal division.
Further, the partial mattresses may be formed by connecting adjacent ones so as to be foldable, or may be separated and independent from each other.

Of these, as the former structure, for example, partial cover bags forming parts of adjacent partial mattresses can be sewn together.
In this case, each partial cover bag may inseparably accommodate the corresponding partial coil spring, while for example, each partial cover bag has an independent portion in which the corresponding partial coil spring is packed in the cover inner bag. The mattress unit may be retractably stored.

Furthermore, in the device according to claim 3, each of the partial mattresses is divided into a plurality of partial mattress units by dividing the cover bag and stitching adjacent ones together so as to be foldable. and each partial mattress unit is a plurality of partial coil springs obtained by dividing the coil spring, each of which is stored in a plurality of unit bags. It is the described coil mattress type futon.

The number of partial mattress units is appropriately changed according to the number of partial cover bags.
The structure of each partial mattress unit is not limited as long as the partial coil spring is housed in at least the unit bag. For example, a partial laminate having a three-layer structure in which front and back paddings made of cotton, urethane foam, or the like are placed on the front and back sides of the partial coil spring, respectively, may be housed in the corresponding unit bag.

The material of the unit bag is arbitrary. For example, various cloths, various synthetic resin sheets, and various leathers may be used.
Also, the configuration of the unit bag is arbitrary. For example, a band-shaped peripheral sheet may be arranged over the entire circumference between the outer edges of the front sheet and the back sheet, and the abutted portions of the sheets may be sewn together flat. Alternatively, the peripheries of the front sheet and the back sheet may be directly sewn flat together.

According to the device of claim 1 of the present invention, the outer peripheral portion of the cover bag is flat without a ridged hem portion. Therefore, when the coil mattress type mattress is laid on the floor, there is no sense of discomfort due to the hem portion of the coil mattress and the mattress. What's more, you can get the comfort of sleeping with coil springs and the unique effects of coil mattresses, such as being hard to get tired even after long-term use, which cannot be obtained with ordinary mattresses containing cotton or urethane foam.

In particular, according to the invention of claim 2, the coil mattress type futon is provided so as to be freely foldable with a plurality of partial futons, so that the coil mattress type futon can be stored compactly.

In addition, according to the invention of claim 3, as the coil mattress type mattress, independent partial mattress units are stored in a plurality of foldable partial cover bags sewn together so that they can be put in and taken out. When the cover bag becomes dirty, it can be removed and washed.
