A stool and desk support system. The system includes a stool base and a desk support surface. A support member may connect the desk support surface to the stool base and support the desk support surface above a floor surface. The stool base may include a stool seat surface and a rocking mechanism opposite the stool seat surface. The desk support surface may be connected to a desk support base by a neck extending from the desk support base. The stool base may include an upper stool base frame and a lower stool base frame. The upper stool base frame may be height adjustable with respect to the lower stool base frame. The desk support base may connect to the upper stool base frame, permitting coinciding height adjustment of the desk support surface and the upper stool base frame.

Adjustment device for a chair which is provided with a rocking mechanism composed of a first plate, fixed to a central gas-operated post for the height adjustment of a seat and to which a second plate is articulated, about a first axis that is transverse thereto and so that it can rock, the second plate being fixed to a seat or being integral with a seat and interacting with elements which are adapted to contrast the rocking of a backrest. A first cable is slideably associated with the first plate and is adapted to activate a lever which is articulated internally to the first plate at a different second axis and is adapted to activate the height adjustment of the seat. A second cable is further slideably associated with the first plate and is adapted to activate a mechanism which allows or prevents the rocking of the second plate.

A platform for lifting an individual from a fallen position is designed to be slid beneath the body of a user and transitions between a collapsed and an extended configuration. The extended configuration raises the individual to a seated position. The platform for lifting an individual has a base platform, a lifting platform, a folding wedge, a set of collapsible supports, and a lift-control assembly. The folding wedge is hingedly connected in between the base platform and the lifting platform so that the folding wedge forms a ramp, while in the collapsed configuration, that is slid beneath the body of the downed individual. The collapsible supports are connected in between the base platform and the lifting platform. The lift-control assembly is mounted in between the base platform and the lifting platform and generates the force required to transition the platform for lifting an individual between the extended and collapsed configurations.

An item of seating furniture, in particular an office chair, having a pedestal with a support column on which a first rotational axis for a backrest is arranged which is pivotable between an upright starting position and a reclined resting position. The backrest is articulately connected in its lower region to a seat part, and when the seat part is in one piece, the articulatable connection is provided about a second axis. When the seating furniture is in the upright starting position, the second axis is arranged below the first axis. The rear seat part is non-rotatably connected to the backrest. The front seat part or the one-piece seat part is supported by kinematicsin relation to the carrying frame. The front seat part or the one-piece seat part is lowered relative to the rear seat part or the backrest by means of kinematics when the backrest is pivoted back.

Provided is a length-adjustable column with a standpipe having a longitudinal axis, a length-adjustment device arranged in the standpipe with a portion displaceably-mounted along the longitudinal axis with respect to the standpipe and an anti-rotation locking device for locking the portion against a rotation around the longitudinal axis relative to the standpipe. The anti-rotation locking device includes an inner element, which is fastened to an outer surface of the portion, and an outer element, which is fastened to an inner surface of the standpipe. The inner element cooperates with positive locking with the outer element against a rotation around the longitudinal axis, and is displaceably guided along the longitudinal axis by the outer element. The inner element is connected with the portion through a substance-to-substance connecting layer.

A chair can include a chair back, or backrest, that is coupled to a base of a chair above a seat of the chair. A tilt mechanism can attach the backrest to the base. In some embodiments, the tilt mechanism can be configured so that the backrest rotates about multiple pivots as it reclines from an upright position to a reclined position to drive motion of the seat during recline of the backrest.
