An adjustable-length column for chairs or the like comprises an upright tube with a pneumatic or hydropneumatic length-adjusting element disposed therein. The latter's piston rod, in the vicinity of its free end, is flexibly snap-engaged with a bottom plate of the upright tube.

Adjustable-length column for chairs or the like

An adjustable-length column for chairs or the like has an upright tube and a pneumatic or hydropneumatic length-adjusting element arranged in the latter, the housing of the element being radially supported in the upright tube and displaceably guided in the direction of a common axis. A profile guarding against twisting is tightly arranged on the housing in particular by shrinking and has at least one radially projecting web which extends parallel to the axis and engages with a groove-like recess of a guide which is non-rotatably connected with the upright tube.
