    Abstract: A piece of furniture comprises a seat, a backrest and a base. At least the seat and the base are movably coupled for reversible relative adjustment in a direction from a first configuration for sitting upright to a second configuration for sitting reclined. One or more support surfaces and a lever are operably coupled to support the seat on the base. The lever rotates about an axis transverse to the seating direction and moves being coupled with the one or more support surfaces at a first support portion defining first lever arm about the axis and a second, different, support portion defining a second, different, lever arm about the axis. The one or more support surfaces define a curved, noncircular path about the axis, such that relative displacement of the support surface and the axis in the seating direction is associated with rotation of the lever about the axis.

    Abstract: 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.

    Abstract: A method and a tilting device for exercising a spinal column of a seated user. The method may include activating a tilting device included in a controllable chair to provide at least one exercise scheme that includes two or more repeatable tilting movements of a seat of the controllable chair around at least two different axes, a number of repetitions for each tilting movement, speed and amplitude of each tilting movement and causing repeatable movements to the pelvis of the seated user as to stimulate movements of all the vertebrae throughout the spinal column of the seated user. The continuous repeatable seat movements may cause the user's spinal column to move between the body's natural vertical midline into a convex shape.

    Abstract: 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 at spaced apart locations. 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 forward motion of the seat during recline of the backrest.
