An adjustable lifting column for adjusting a piece of furniture comprises a drive assembly, a threaded spindle assembly comprising at least two concentrically arranged threaded spindles, of which an outer threaded spindle concentrically surrounds at least one further threaded spindle, a telescopic tube assembly comprising three concentrically arranged telescopic tubes, and a driver mechanism having an internal thread. The threaded spindle assembly is located within the telescopic tube assembly. Two adjacent threaded spindles of the threaded assembly have a common threaded connection. One of the at least two threaded spindles in the threaded spindle assembly is connected to the drive assembly for driving this one threaded spindle. The outer threaded spindle also has an external thread in which the internal thread of the driver mechanism engages. The driver mechanism is connected to a middle telescopic tube of the three telescopic tubes.
