A device that prevents the self-adjustment of a leveling glide for the tubular legs of various types of furniture, including tables and chairs, is disclosed. The device comprises a threaded insert for a furniture leveling assembly that includes a polymeric washer secured to the bottom of the threaded insert. The polymeric washer is aligned with the axis of the internally threaded of the threaded insert and has a hole diameter that is smaller than the diameter of the externally threaded stem of the leveling glide.

The height-adjusting stool is a seat, which may change height between a minimum height and a maximum height by activating a motor to move a scissor jack located beneath the seat. The motor may be battery-operated. A plurality of wheels may allow the height-adjusting stool to be repositioned by rolling to one side or the other. One or more wheel locks may prevent the plurality of wheels from rolling when stationary positioning is desired. A three-position switch may allow the user to move the seat up or down or to cease motion of the seat.

An anti-wobbling adjustable height stool includes an adjusting screw vaving a threaded seat support spindle and a top spindle head and a stool seat assembly. The stool seat assembly includes a stool seat, and a connecting frame connected with a bottom of the stool seat. The connecting frame is opened with an installation hole, and the spindle head penetrating through and being arranged in the installation hole to enable a tight fit of the spindle head with the connecting frame.

A linear actuator for a furniture system comprises at least one axial flux motor (5) having a rotor (9), and at least one motion mechanism (6) attached to the rotor (9). The motion mechanism (6) is adapted to cause a linear movement of the linear actuator.

An electrically adjustable furniture system comprises at least one such linear actuator. A furniture system arrangement comprises at least one first and at least one second such electrically adjustable furniture system. A method of installing a linear actuator in a furniture system comprises the steps mounting at least one axial flux motor (5), mounting at least one motion mechanism (6), and connecting the at least one motion mechanism (6) to a rotor (9) of the at least one axial flux motor (5).

The invention relates to a piece of seating and supporting furniture with a seating and supporting body, comprising: a height-adjustable column; a seating and supporting body, which is mounted pivotably about at least one horizontal axis between a first end position and a second end position at a first end of the height-adjustable column; a stopping mechanism, which is situated at a second end of the height-adjustable column; and a locking mechanism for releasably locking the stopping mechanism. A seating and supporting piece of furniture which allows reliable and user-friendly operation is created according to the invention in that a transfer device is used to release the locking of the stopping mechanism by the locking mechanism via the pivoting of the seating and supporting body between the first end position and the second end position.

A motorized tilting mechanism for a reclining chair allows the chair be placed in a zero gravity position. A base frame comprising 2 sub-frames pivot in relation to each other to provide simple tilting mechanism.

Storage of chairs when not in use, for instance in halls used by various groups, is a common problem which has been addressed by providing chairs that are stackable upon one another. Usually, this requires the chair to be composed of sloping legs and a sloping backrest, such that the seat of a lower chair can fit between the legs of an upper chair, and the backrest of the upper chair can rest on the backrest of the lower chair. It is desirable to be able to stack chairs with as small a vertical displacement as possible, usually limited by the depth of the seat, which is typically substantially horizontal. For instance, the base of an upper seat may sit (when stacked) on the upper portion of a lower seat. However, these chairs are usually mass produced and so designed to fit the average shape, which is not accommodating for a lot of people. The present invention provides a chair where seat 13 height, back 3 angle, seat 13 tilt and seat 13 roll are adjustable.

A stool comprises a height-adjustable seat. The seat is coupled to a stem of the stool using a ball and socket mechanism. The ball and socket mechanism enables the seat to be tiltable up to 20 degrees in all directions about a vertical axis. The ball and socket mechanism aids in providing the seated individual with an increased range of motion. The range of tiltable motion can be adjusted using an adjustment member.
