A chair includes a seat (2) and also includes a pair of thigh support elements (17) pivotal n a generally downwardly direction about front pivot axes (20) from a first state forming with a central seat element (15) a substantially common plane, to a second downwardly extending state. The elements (17) are also pivotal about second pivot axes in a generally rearwardly direction for urging the user's thighs away from each other for stretching the adductor muscles. Foot support members (49) extend transversely and sidewardly on respective opposite sides of the chair (1) from a support element (46) for supporting the foot during a stretching exercise with the corresponding thigh of the subject extending downwardly from the seat (14) and the lower leg extending from the knee in a upwardly inclined direction to the foot support member (49) for stretching the quadriceps and the hip flexor muscles of the subject.

A mechanism is provided for a seating unit that moves the seating unit between closed, TV, and fully reclined positions. The mechanism allows independent movement of a seat frame, relative to the chair arms and chair back to which the mechanism is mounted. The mechanism thus allows the seat depth of the chair to be adjusted relative to the chair back to accommodate the individual characteristics of the chair occupant.

A chair assembly includes a supporting frame disposed above a base and including a first guiding groove. A seat is pivotably connected to a backrest. Lower and front guiding wheels are mounted to rear and front ends of the seat, respectively. At least one operating board includes rear and front ends respectively having second and third guiding grooves. The lower guiding wheel is movably received in the first and second guiding grooves. The front guiding wheel is movably received in the third guiding groove. A first operating rod is pivotably connected between the supporting frame and the seat. When the operating rod retracts, the lower guiding wheel is located in rear ends of the first and second guiding grooves, and the front guiding wheel is located in a rear end of the third guiding groove. The seat moves downwards and rearwards, and the front end of the seat inclines upwards.

Powered chairs, assemblies for use in the powered chairs, and components for use in the assemblies are provided. Electrical systems for use in the powered chairs, and components for use in the electrical systems are provided. Control systems and methods for operating powered chairs are also provided. Any given chair may be locally and/or remotely controlled.

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 piece of seating furniture with a base for setting up in a fixed position, a seating element tiltable in relation to the base and having a seating surface, and a leg support element movable in relation to the seating element and having a leg support surface. The leg support element is connected to the seating element via a link gear, wherein the leg support element is movable between a storage position and a use position via the link gear. An electric motor is provided below the seating surface, which acts on the link gear via a push rod. To connect the leg support element to the seating element, the link gear has a pivoting link which, during the transfer of the leg support element from the storage position into the use position, is arranged in part in a slot partially penetrating the leg support surface.

A spring actuated rocking mechanism can be attached to the legs of a collapsible chair to allow for the user to rock in the collapsible chair. The mechanism may be attached at the factory or retrofitted to the chair. The rocking mechanism can be attached to the end of a leg or disposed within a leg, having a leg portion above and below the mechanism.
