It is not conducive to the use of chairs by students during breaks.

In order to realize the multi-purpose of the chair, a kind of foldable chair appears on the market now. By widening or lengthening the seat surface, the chair can realize the functions of "sitting" and "lying" simultaneously. In existing folding chairs, a panel is usually added on the front side or the left and right sides of the normal chair surface, and a pair of chair legs are arranged on the bottom surface of the board. In the folded state, the chair legs are stored together with the panel on the front side or on the left and right sides of the chair surface. At this time, the user is not sitting or standing; in the open state, the chair legs are opened and placed on the ground. In the same plane, the seat surface increases, and the user can lie down at this moment. Although this kind of folding chair has both the functions of "sitting" and "lying", it needs to increase the number of chair legs for support, and the product structure is complicated.
