An adjustable table top (7, 105) is supported movably on a trestle having at least one abutment (5, 104) fixed thereto beneath the table top. The abutment coacts with a wedge-shaped intermediate piece (9, 106) which is displacable in an opening direction of its wedge angle, substantially parallel to the table top, and which can be introduced to a lesser or greater extent into a space between the abutment and the table top so that a distance between the table top and the abutment and, thus, the position of the table top relative to the trestle, are determined by the position of the intermediate piece.
