Abstract: The present application relates to a lifting column for furniture, in particular for a table. The lifting column comprises a first element and also a second element. The second element is introduced at least somewhat into the first element. The first element has a spindle which extends along the longitudinal axis of the first element and projects at least somewhat into the second element. The second element has a rotor which is mounted in a rotatable manner in the second element, and has at least one rolling body which runs in or on a thread helix of the spindle. The rotation of the rotor relative to the spindle causes a linear movement of the second element relative to the first element. The second element also has an arresting device which, in a first state, blocks the rotation of the rotor relative to the spindle and, in a second state, frees the rotation of the rotor relative to the spindle. At least one leg spring is clamped between the rotor and a fastening element which is fastened on the second element, and the leg spring therefore subjects the rotor to a prestressing force. Therefore, a lifting column having a weight compensation function can be created.
