ABSTRACT:
The invention achieves a chair in which a shape of a backrest surface can be three-dimensionally changed while following a motion such as a sitting person looks around while sitting or the like. In a chair provided with a backrest in which an upper portion of a backrest surface is supported by a plurality of frame elements arranged so as to be spaced with each other in a width direction, the respective frame elements are independently movable backward and forward.
