Abstract

A guide bush for an adjustable length column for chairs, tables or the like is provided, in its inner portion, with a slide bush concentric of a central longitudinal axis for the guidance of a cylindrical housing of a gas spring. The outside wall of the slide bush is provided with spaced ribs for the reception and support, radial to the axis, in an upright tube of the column. The ribs are elastically deformable radially to the central longitudinal axis.
