Gas lift chairs are a form of the office chair that allow the user to modify their height in relation to the height of a desk, leading to an increase in comfort and ergonomic benefit.

The concept of using a gas spring to aid the adjustment of chairs is described in patent GB1261658[1], issued in 1972 to Drabert Soehne of Minden, Germany and cites the inventor as Drabert Fritz.
