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