ABSTRACT:
A foldable chair supported by rear supporting legs is disclosed. The rear supporting legs are directly connected to a seat. A positioning structure for resisting against the seat is installed at the fulcrum of the front supporting leg. When the seat is expanded, the fulcrum of each supporting leg practically suffers force from the seat, thus the force is distributed uniformly to the four legs. In using, even the user leans against the chair back, the chair may be still steady. The chair back has a cambered surface. After being folding, the volume occupied does not increase. Therefore, the packaging material will be saved.
