Abstract
A chair column comprises a stand tube. A support bush is inserted into the upper end portion of the stand tube. A gas spring cylinder extends axially through the receiver bush. The piston rod is directed downward and is connected with a bottom of the stand tube. The gas spring cylinder is guided through two axially spaced bearing bushes. The bearing bushes are radially supported by the receiver bush through a radially prestressed transmission ring or a plurality of circumferentially distributed buffers. The radial prestress is transmitted to the contact face between the bearing bushes and the gas spring cylinder.
