Embodiments of the invention include an apparatus for positioning an electronic display. The apparatus can be combined with an existing work surface to provide a multi-position workstation. In some cases the apparatus includes a mounting portion configured to support an electronic display and a keyboard. The mounting portion may be movable with respect to the work surface between multiple positions, including for example, a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.

A height adjustment mechanism for an adjustable height table includes an outer sleeve, an inner sleeve, a plug, and a locking mechanism. The outer sleeve is disposed outside the inner sleeve, and the outer sleeve and the inner sleeve are slidable relative to each other. The plug is disposed outside the inner sleeve, and is slidably connected to the inner sleeve. The plug is disposed at an upper end of the outer sleeve, and an outer wall of the plug includes a pressing portion. The locking mechanism operates to push the pressing portion tightly against an outer wall of the inner sleeve to increase the friction between the plug and the inner sleeve, so that the plug and the inner sleeve are relatively fixed.

A vertically adjustable support or table with legs each having a pneumatic foot assembly operated to engage roller ball assemblies on the floor surface thereby allowing the table to be rolled. Each pneumatic foot assembly has a piston unit which is operated by pressurized air from a source, which is controlled by a valve on the table, and which is fluidically connected to a piston chamber of the pneumatic foot assembly. Once the table has been rolled across the floor and is in a desired location, the control valve is operated to release the air from the piston chamber and to rest a circular rim of the pneumatic foot assembly, and therefore, the legs of the table firmly against the floor surface for a stationary or fixed positioning of the table.

A pressure-adjustable gas spring includes a first gas spring and a gas source for adjusting a pressure. One end of the gas source is connected with the first gas spring and another end is connected with an adjustment device for adjusting the volume of the gas source. The adjustment device includes a cavity for accommodating the gas source and a piston. One end of the piston opposite the gas source is connected with a driving subassembly. The driving subassembly includes a screw. One end of the screw is connected with the piston and another end extends out of the cavity. A nut is arranged on the end of the screw extending out of the cavity. A connection tube is arranged outside the nut in a sleeving manner. One end of the connection tube is connected with the cavity and a rotating block is mounted at an opening of another end.
