This invention concerns a height-adjustable work bench (1) with an upper platform (2) and a lower base element (3), a frame that is variable in height and arranged between the platform (2) and the base element (3), each end of which frame has an upright first leg (4) and a second leg (5) disposed parallel thereto and at a horizontal distance therefrom that supports the underside of the platform (2), which legs (4, 5) are pivotably connected by means of a lower arm (6) and an upper arm (7) parallel thereto to produce a deformable parallelogram (4 - 7), and with a drive system to raise and lower the platform (2) of the work bench (1) by changing the angle between the parallel arms (6, 7) and the upright first leg (4). The novelty thereof consists in that the platform (2) is mounted displaceably in relation to the second leg (5) and transversely to the plane of the parallelogram (4 - 7), that the parallelogram (4 - 7) includes a plate (8) with an oblong, non- linearly recess (9) that accommodates a slide (12) that is connected to the parallelogram (4 - 7) in such a way that a change in the angle between the parallel arms (6,7) and the upright first leg (4) results in displacement of the slide (12) along the recess (9), as well as movement of the slide (12) in the plane of the plate (8) and transversely to the recess (9), and in that the movement of the slide (12) is transferred to displace the platform (2) so that it alone is raised or lowered vertically.
