In conference rooms or in special conference hall seating, swivel chairs must automatically return to their starting positions after use. This will result in a neat-looking conference table or conference hall. The multi-function column STAB-O-MAT MC from Stabilus meets exactly those requirements. Due to a patented functional element in the gas spring column, when the occupant gets up, the swivel chair will return to the highest seat position and to its original direction. This function is available for a standard tube diameter of 50 mm and certain taper lengths.
