Abstract: An office workstation with a table plate (2) which rests on a lower frame (6). At the front left or right-hand side the table plate has an oblique edge (44) against which attachments, particularly plates (50,60) can be placed. The table plate is mounted on the lower frame (6) with a height adjustment device (68). The height adjustment device engages in through-openings (28) in the table plate (2). Support arms (12, 48) of an upper frame are to be firmly connected to the lower frame through these openings, when required. The upper frame can carry additional components (75,76) such as storage shelves or a vertical wall (16). The lower frame is composed of legs (7), which can serve to guide cables, and joint bodies (18,160) which are hollow and represent the connection between the legs and horizontal hollow beams (22,23,24,116). The hollow beams are accessible from the exterior through a flap (118) extending over their entire length.
