ADJUSTABLE SEATING AND FURNITURE

摘要

Self-adjusting furniture, seating, and accessories disclosed. When the user applies a force to the seating by shifting his or her center of gravity, the backrest and/or seat/bed portions of the seating/furniture move in response to the force to recline or adjust the seating/furniture or accessories. The user can return the seating to an upright position by again shifting his or her center of gravity. The angle of the backrest and/or seat/bed portions can vary relative to the ground as the user moves. Continuously varying the angle of both the backrest and seat/bed portions of the seating/furniture or accessories relative to the ground may improve a user's seating comfort, for example, by decreasing or negating the user's need to shift position on the seat when reclined or continuously responding the user's shift in position.
