Abstract
A length-adjustable column for chairs, tables or the like has a length-adjusting element and a stand pipe. The stand pipe is in the form of a composite pipe and has an outer tube and an inner guide tube, which are connected with each other by guide webs. On the internal surface of the inner guide tube, partial cylinder surfaces are produced by chip removal as guide surfaces for the cylindrical housing of the length-adjusting element.
