ABSTRACT:
A longitudinally adjustable column for chairs, tables or the like comprises an upright tube and a length-adjusting element arranged in the upright tube. For fastening to a pedestal a sleeve-like cone section is provided, which is provided on its internal side with at least one recess, with which engages a projection. Over the length of the upright tube several of such projections are provided at a distance from each other, so that the cone section formed by half shells or being simply slotted can be fixed in different height positions on the upright tube in the direction of the axis.
