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.

A height adjustable device including a counterbalance mechanism configured to be affixed adjacent to a rear portion of a vertical support member, a worksurface configured to be affixed adjacent to a front portion of the vertical support member, and a mounting member configured to slidably couple the worksurface to the counterbalance mechanism; wherein a portion of the mounting member extends through an opening defined in the vertical support member.

A variable height workstation system includes a base, a variable height platform, a lift mechanism, and a sensor arrangement. The lift mechanism is configured to move the variable height platform within a range of motion between a fully lowered position and a raised position. The sensor arrangement is operatively connected to the variable height platform. The sensor arrangement is configured to sense the position and movement of a user on, above and around the variable height platform for outputting data to determine how the user is positioned on, above and around the variable height platform in comparison to a predetermined target position.

An elevation working platform includes a lower support and an upper support. At least one group of X-type elevation mechanisms is provided between the lower support and the upper support. The elevation working platform further includes an elastic element. A first end of the elastic element is connected between two end points of a first support rod or a second support rod. A second end of the elastic element is connected to the lower support or a second hinging seat capable of sliding relative to the lower support. Using the X-type elevation mechanisms, the front and back positions of the upper support do not change in an elevating process of the upper support, the structure is simple and practical, and the cost is relatively low.
