If you sit straight for a long time, your feet will suffer from pain and numbness. Can't move after sitting straight.
There are seat chairs introduced in the technical field, but they are difficult to carry and stable.

Make a strut that combines two plates (the technique of braiding), and the two plates that make up the strut,
Connect to the board that sits and the board that touches the floor so that they bend at right angles.
The state where the support is combined is a chair. The disassembled and folded state becomes two sets of two plates.

The size of the column is smaller than the size of the gap between the left and right ankles when a person sits down, and the sense of disturbing contact with the chair is eliminated.

By assembling the struts at almost right angles, the same feeling of stability as when using large log struts can be obtained.

    It becomes lighter by using materials such as wood.
