<p>The table has a table top portion (A) intended for use as a working surface and a table top portion (B) intended for use as an additional supporting surface. The two table top portions (A,B) are adjustable in height conjointly or separately. The vertical member (100,200) for supporting the table top comprises at least two tubular members (101,102; 201,202,219) arranged one into the other so as to be axially movable relative to each other, drive means (105,106; 205,206; 223,224) adapted to impart an axial motion to the movable tubular members (102;202,219), and control means (300) arranged so as to permit a conjoint height-adjustment of the two table top portions (A,B) or a separate height-adjustment of one of the two table top portions (A,B) relative to the other. <IMAGE></p> |
