Abstract

A vertically adjustable column, in particular for chairs or tables, includes a pedestal tube having a coaxially arranged lengthwise adjusting element, e.g., a gas spring, and a rotational fixation profile engaging a counterpart profile extending parallel to the longitudinal centerline of the pedestal tube. The rotational fixation profile and the counterpart profile are operatively arranged between the pedestal tube and the lengthwise adjusting element, and one of the profile parts is arranged in series with the lengthwise adjusting element.
