A seating arrangement includes a seat assembly slidably movable between a forward most position and a rearward most position and that includes a seat support structure configured to support a seated user thereon, and at least one elongated slide bearing attached to the seat support structure and including a bearing surface and at least one stop member, wherein the bearing surface and the at least one stop member are a single, integral piece. The seating arrangement further includes at least one slide support member that slidably supports the slide bearing thereon between the forward most position and the rearward most position, wherein the at least one stop member is configured to prevent the seat assembly from being moved beyond at least one of the forward most position and the rearward most position.

A piezoelectric adaptive mesh includes multiple piezoelectric fibers that include piezoelectric structures that can act as sensor and/or actuators to enhance a person's comfort. The piezoelectric structures communicate with a controller and/or a software processing system and may identify the position of a user and make adjustments through the actuators to increase user comfort by providing support, assistance, treatment, and/or temperature adjustment.

An adjustment device for a chair, comprising an oscillating mechanism composed of a first plate, associated with a central gas-operated post for the height adjustment of a seat. A second plate is articulated to the first plate so that it can oscillate, by means of a pair of first pivots and is fixed to a backrest. A linkage is articulated to the first plate, by means of a second pivot, and is in turn articulated, by a third pivot, to a third plate, with which the seat can be associated. The third plate is articulated to the second plate. Elements are associated with the linkage for connection to at least one slat or leaf spring, which is arranged on a plane that is substantially parallel to the plane of the seat and is adapted to elastically contrast the inclination of the second plate with respect to the first plate.

A rocking device includes: a seat which supports a body of a user; a motor which rotates a rotation shaft in a first rotation direction and in a second rotation direction that is a rotation direction opposite to the first rotation direction, and thereby supplies motive power for rocking the seat via a gear attached to the rotation shaft; and a controller which controls rocking of the seat via the motor. The seat is configured to make a first motion of moving in a first movement direction, in accordance with rotation of the rotation shaft in the first rotation direction, and make a second motion of moving in a second movement direction, in accordance with rotation of the rotation shaft in the second rotation direction. The controller is configured to control rocking of the seat such that a prescribed stopped period is provided between the first motion and second motion.

A recliner system, including a suspension point adapted to be mounted onto an upright anchor and to extend outwardly therefrom. The recliner system further includes a support platform and a plurality of cords, each attached to the support platform at two attachment points and suspended from the suspension point. The support platform is adjustable between an upright position and a reclined position by pulling on at least a subset of the plurality of cords.

The invention relates to a hanging chair that contains a frame (2), suspension (50) that may be secured to the frame (2) and a first canvas (70) determining a seat (72) supported by the frame (2), characterised by that the frame (2) contains three ring-shaped frame elements (10, 20, 30), of which—a first and second frame element (10, 20) are secured to each other along a first axis (125) with a first pair of fasteners (123, 124), —the second and a third frame element (20, 30) are secured to each other along a second axis (235) on a side of the second frame element (20) opposite the first axis (125) with a second pair of fasteners (233, 234), and—the first and third frame elements (10, 30) are secured to each other along a third axis (135) on a side of the first frame element (10) opposite the first axis (125) with a third pair of fasteners (133, 134), and with the frame elements (10, 20, 30) secured to each other and in suspended state, the suspension (50) is located outside of the frame (2), above the first frame element (10), while the second pair of fasteners (233, 234) securing the second and third frame elements (20, 30) to each other are located below the first frame element (10), the seat (72) of the first canvas (70) is located outside of the frame (2), outwards from the second frame element (20), and the third frame element (30) delimits a seat opening (33) permitting access to the seat (72). The invention also relates to a virtual reality simulator that contains such a hanging chair.

A chair comprises a seat pan member, a seat back member having a lumbar support member, a lumbar support assembly operatively connected to the lumbar support member and configured for moving the lumbar support member, with respect to the seat pan member and the seat back member, between at least a first position and a second position, and an actuator configured to operate the lumbar support assembly for movement of the lumbar support member between at least the first position and the second position. When the lumbar support member is in the second position, the lumbar support member is positioned forwardly, in a direction toward the seated user's lower back, relative to the seat back member so as to enable the user to be seated forwardly on the seat pan member while being engaged with the lumbar support member.
