The present invention relates a height-adjustable desk including: a base; a top board provided so as to be vertically elevated with respect to the base; a link mechanism disposed between the base and the top board so as to support a top board such that the top board may be elevated and including a plurality of link members; a height-adjusting means formed to be extendable at a desired length and determining the height of the top board with respect to the base according to a length thereof; and an operating means for fixing the height-adjusting means so that the height-adjusting means maintains the desired length.

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 liftable table has a table frame, a fixing board, a lifting device, and a table board. The table frame has a main frame and a holding seat. The holding seat is deposited on the main frame. The fixing board is mounted on the main frame. The lifting device is deposited on the holding seat and has a driving set and at least one crossing set. The crossing set is extended from or folded in the receiving space of the holding seat, and is connected to and driven by the driving set. The table board is deposited on the crossing set to move upwardly or downwardly. A user views and operates a computer put on the table board with a sitting or a standing posture, and this prevents the user from using the computer with the sitting posture for a long time and avoids damages to the user's health.

Embodiments include an apparatus for positioning items such as an electronic display, a keyboard, and/or a work surface. The apparatus can be attached proximate an edge of a generally planar support member to provide a multi-position workstation. In some cases the apparatus includes a display mount coupled to a support column and configured to support an electronic display and a keyboard. The support column may be movable with respect to support member between a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.
