A chair device, wherein the chair has a base, an upright, length-adjustable supporting column which at the bottom is connected to the base, and a seat device which is tiltably or non-tiltably connected to an upper region of the supporting column. A lower, elastically resilient coupling forms a tiltable connection between the base and a lower portion of the supporting column. The lower coupling is designed to permit tilting of the supporting column relative to the base in any one of 360° of tilting direction or only in one tilting direction.
