An automatically adjustable chair structure essentially includes a chair body, a base, an extension bar, at least one first cushion mechanism, and at least one second cushion mechanism. When a user sits on the chair body, the user's body weight is cushioned by the first and second cushion mechanisms. In addition, the two sled runner-shaped supports lying on the floor and the pivotable design of the extension bar allow the extension bar to move backward. Thus, the tilt angle of the chair body can be automatically changed to suit the user's sitting posture. |
