CONSTITUTION: A chair comprises: four legs of dual structure; a contact hole(1a,2a); and a connecting bolt(1b,2b); and attached and detached cushion and a seat back. Four legs of dual structure are formed by assembling a connecting bolt into a contact hole(1a) formed in a frame. The cushion and seat back are attached and detached by assembling the connecting bolt(2b) in the contact hole(2a) formed in frame. A user can more stably use the chair without shaking and contortion even when the chair is manufactured more long.
