Abstract
In lifting columns (1) for tables and similar articles of furniture and consisting of pipe profiles (2a, 2b) with intermediate slides (8), it is a problem that the profiles (2a, 2b) have relatively great dimensional tolerances. This means that the gap between two successive sections may vary relatively much, which causes a great play in the column. This is solved in that at least one of these sections (2a) at one of the slides (8) is formed with a local deformation of the wall inwards toward the slide to press the slide inwards against the following section (2b). The dimensional tolerances may be neutralized by suitable arrangement and selection of deformations as well as the force with which the deformation is made.
