In the case of a height-adjustment device for a table (1) with three or more table legs (3.1 . . . 3.4) arranged in an edge region of the table, with respectively adjacent table legs (3.1 . . . 3.4) being connected to one another by a horizontal, hollow-profile connecting element (4.1 . . . 4.4), each of the table legs (3.1 . . . 3.4) comprises a telescopic mechanism for changing a length of the table leg (3.1 . . . 3.4), which mechanism can be adjusted by rotating a rotatably mounted adjusting element (7.1 . . . 7.4). A plurality of coupling elements (9.1 . . . 9.4) are accommodated within the connecting elements (4.1 . . . 4.4) and are arranged in such a manner that each of the adjusting elements (7.1 . . . 7.4) of the table legs (3.1 . . . 3.4) is mechanically synchronized with the adjusting elements (7.1 . . . 7.4) of the adjacent table legs (3.1 . . . 3.4) by means of separate coupling elements (9.1 . . . 9.4).
