Abstract: In various embodiments, self-adjusting reclinable seating is disclosed. When the user applies a force to the seating by shifting his or her center of gravity, the backrest and seat portions of the seating move in response to the force to recline the seating. The user can return the seating to an upright position by again shifting his or her center of gravity. Such a configuration eliminates the need for manual recline controls. The seating is further configured to continuously vary the angle of the seat and backrest portions relative to the ground as the user moves. In particular, vertical distance between the front of the seat and the ground increases as the backrest reclines. Continuously varying the angle of both the seat and the backrest portions of the seating relative to the ground may improve a user's seating comfort, for example, by decreasing or eliminating the user's need to shift position on the seat when reclined.
