<p>[Problem] To provide a comfortable chair with a backrest. [Solution] A chair with a backrest characterized by comprising core sheets (9, 12, 13, 14) and a chair sheet material (103), and in that the chair sheet material (103) is attached to chair support frames (20, 21, 22, 23, 24, 25). The core sheets (9, 12, 13, 14) are formed of an elastically bendable material, have elastic resilience so as to naturally assume a backrest shape, and also can be elastically displaced by a stretching force during use while a backrest state is maintained. The chair sheet material (103) is provided with buffer sheets (15, 16) which overlap the surface of the core sheets at the side facing the back of a seated person during use. The chair support frames (20, 21, 22, 23, 24, 25) are lower than a seating surface and have the chair sheet material attached thereto in a state where the core sheets and the buffer sheets are positioned at the rear surface of the back and head of the seated person.</p> |
