Device for height adjustment of a table top (2), such as a writing desk, which device comprises a support beam (1) and in which between this and the table top a lifting mechanism is present. The table top is near two opposite sides supported by a substantially V-shaped support (6) with arms (7, 8) the free ends of which are connected to the table top (2) by means of first pivot shafts (5). The top of each support (6) is connected to a first carriage (11) by a second pivot shaft (10), said carriage being movable along said support beam (1). The centre (9) of said V-shaped support (6) is connected to a lever (13), the other end of which is connected to a second carriage (17) movable along said support beam (1) by electro motoric driven means (18, 19, 20) or in an equal way.
