An armchair comprising a seat chassis supported on a support chassis by a pair of support columns, a chair back structure pivotally attached to a rear end of the seat chassis and to the support chassis, and a leg support structure pivotally attached to a front end of the seat chassis and connected to a beam, wherein the beam is attached the chair back structure. A first actuating device is mounted to the chair back, where a protracting end of the first actuating device is connected to the seat chassis. The armchair further comprises a second actuating device mounted to the support chassis, a footrest connected to a protracting end of the second actuating device, a third actuating device attached to the seat chassis, and a seating structure connected to a protracting end of the third actuating device and mounted above the seat chassis, wherein the seating structure includes an operative position projecting upwards and forwards by the third actuating device at a tilting angle from the seat chassis.

A linkage mechanism provides motion capabilities for various chair types. For example, a linkage mechanism includes a combination of links that facilitate ottoman extension/closing and backrest recline/incline. In addition, a linkage mechanism includes a compact design that is usable with hi-leg style chairs having a relatively low seat height. A seating unit with a motorized linkage mechanism is also provided.

A reclining and declining chair, preferably one that rotates with respect to its base, having a chair seat frame or plate and having a vertical or generally vertical member that extends beneath to support is reclined and declined by tilting at least an upper portion of the vertical or generally vertical support. Optionally the chair can also have a reclining backrest and a leg/foot rest that can be raised and lowered. The tilting, reclining, declining and raising and lowering motions are accomplished by drive mechanisms that can be manually powered, electrically powered, fluid driven, etc. with operator controls allowing increased range and ease of reclining, declining plus other desirable advantages with these types of chairs.

Sitting furniture (100) comprising a seat (110), a lower leg support (120) and a chest support (130). The invention is characterised in that the seat (110) is arranged to support the posterior thigh (11) and/or buttocks (12) of a seated user (10) such that the femur bone (13) of the seated user (10) is downwards inclined in the anterior direction at an angle of at least 40° downwards in relation to the horizontal, in that the lower leg support (120) is arranged to support the anterior side of the lower legs (14) of the seated user (10), and in that the chest support (130) is arranged to support the chest (15) of the seated user (10) in a forward leaning position of the seated user (10) such that the third lumbar vertebrae body (16) of the seated user (10) is arranged in a support plane (150), which support plane (150) is perpendicular to the sagittal plane of the user and in which support plane (150) the respective pivot point (17) of the seated user's (10) hip joints and the respective pivot point (18) of the seated user's (10) shoulder joints are also arranged when the posture of the seated user (10) is symmetric about the seated user's (10) sagittal plane.

A furniture member may include a base frame, a seat assembly, a drive rod, a legrest mechanism, and a wall-proximity mechanism. The seat assembly is supported by the base frame and includes a seat frame, a seat bottom, a seatback and a legrest. The legrest is movable relative to the base frame and seat frame between a retracted position and an extended position. The seatback is movable relative to the base frame and seat frame between an upright position and a reclined position. The drive rod is rotatably mounted to the seat frame. The legrest mechanism is attached to the legrest and the seat frame and is driven by the drive rod. The wall-proximity mechanism is connected to the base frame and to the seat assembly and tilts the seat frame rearward relative to the base frame and translates the seat frame forward relative to the base frame.
