    • The present invention relates to a lifting column comprising at least two telescopically arranged members and a drive unit located in the hollow hereof. The drive unit comprises an electric motor, a transmission and a spindle unit with a number of spindles and at least one spindle nut. The electric motor drives the spindle unit via the transmission. The drive unit is connected to the at least two telescopically arranged members enabling a longitudinal displacement of the telescopic members, such that they are extended out of or retracted into each other depending on the direction of rotation of the electric motor. The lifting column comprises at least one supporting element attached to a spindle, where the supporting element is configured to abut the inner side of a surrounding member. Thus, a strong construction is achieved as the supporting element prevents the spindle unit from deflecting, as a horizontal force resulting from a high axial load or torque will be transferred to the members via the supporting element.
