PROBLEM TO BE SOLVED: To provide a chair that can reliably support the back of a seat occupant, and, when a stance of looking back from one side in a width direction to the rear is taken, can follow the stance.SOLUTION: A chair 1 includes: a leg body 10; a backrest support body 20 supported by the leg body 10; a backrest rear part support member 40 supported by the backrest support body 20; and a backrest 50 supported by the backrest rear part support member 40 that supports the back of a seat occupant. The backrest 50 includes: a stretched material 51 that receives the back of the seat occupant and has flexibility which enables deformation following the stance of the back; and a pair of vertical frame parts 53A and 53B spaced in a width direction which are fitted to the stretched material 51, whose lower end is connected to the backrest rear part support member 40, and which are twist-deformable in response to the force applied from the stretched material 51. |
