DESCRIPTION OF RELATED ART[0002]Collapsible chairs having a foldable frame and a soft panel attached to the frame have long been developed. They are able to be folded for saving storage space. Early collapsible chairs need a relative complex process of folding and expanding. They often require two hands and several steps. Some recent collapsible chairs have been improved and need only one hand and one step of action of user to either fold or expand the chairs. However, backrest adjustment of such simply operable collapsible chairs is still an untackled problem.
