PROBLEM TO BE SOLVED: To provide a chair which fits a motion of a user completely when the user sits on the chair and leans against a backrest by being added with not only a function bending in a front/rear direction but also a function bending in a right/left direction.SOLUTION: A backrest 1 is formed by including: a fabric bag 6 comprising plural vertically long bags inside; and plural bending plate materials 5 having a square pole shape (bamboo material, bending wood, resin, or a material similar to the resin) inserted into the vertically long bags. Individual bending plate materials 5 having a square pole shape inside the back rest 1 are moved independently, thereby the chair performs a bending function not only in a front/rear direction but also in a right/left direction, the backrest fits the back and is bent. The chair can adjust an angle between the backrest and a seat to be natural and appropriate and can follow the back of each user closely.SELECTED DRAWING: Figure 1 |
