A swivel-chair (10) has a frame (15) on which a seat (24) is movably mounted. A back (22) is connected with the seat (24), and this back (22) may be turned around a connecting point (19) at the frame (15). At this connecting point (19) a rotary spring (40) is provided, which tends to turn the back (22) into its working position, and the seat (24) is supported and guided at a seat-guide (31) at its forward area, that is where the thighs of the user are resting. This seat-guide (31) is preferably made such, that it will keep the inclination of the seat (24) on movement thereof, thus the so-called seat-slope, at an ergonomically advantageous value. A movement into the rest position goes against the rotary spring (40) and if required also the seat-guide (31) Optionally a blocking-device (45) for the seat (24) may also be provided in order to be able to block the seat (24) in any desired position in accordance with the wishes of the user.
