A height adjustable desk includes a work surface, a first telescoping leg, a second telescoping leg, a driving device, and a switch device. The first telescoping leg and the second telescoping leg are connected to the work surface, and are driven by the driving device to lift or low the work surface to any desired height. The switch device is mounted on the first telescoping leg to be activated when the work surface is moved to a predetermined position. The switch device will turn the motor off to stop the work surface when the switch device is activated.

A foldable table includes a top plate, two leg units, and a telescopic support unit. Each leg unit includes two legs connected to and pivotable relative to the top plate. The telescopic support unit includes two support members, a first telescopic subunit, and a lock subunit. The support members are respectively mounted on the leg units. The first telescopic subunit is connected between the support members, and has an inner tube and an outer tube that is sleeved on and is slidable along the inner tube. The lock subunit is operable between a lock state and an unlock state for locking or unlocking sliding movement between the inner and the outer tubes.

A height-adjustable desk is disclosed. Exemplary implementations may include a work surface, a left-side support structure, a right-side support structure, a core body, and a working body that provides the work surface. The core body may include lifting mechanisms such that the work surface of the desk may be positioned for a person in a standing and/or sitting position. The working body may include a control interface configured to be manually engaged by the user, to control lifting and/or lowering of the work surface of the desk.
