ABSTRACT:
A longitudinally adjustable column for chairs, tables or the like, comprising a vertical tube and a longitudinal adjusting element arranged inside the tube. The longitudinal adjusting element has a cylinder with an axially movable piston rod, and is mounted on a base plate which is held in place inside the tube. The base plate is held in place on one side by an inwardly-bent deformation of the vertical tube, and on the other side by at least one supporting surface on the inner wall of the vertical tube. The deformation is formed by bending a face at one end of the tube in the direction of the inner wall of the tube, so that the outer wall of the tube rests against one side of the base plate.
