A known advantage of the different dynamic seating positions on a chair is obtained with a novel combination of several known parts which nonetheless depend on each other for their movement capacities through a logical coupling. The position of the outstretched hand of a user in relation to the table hardly changes, while the seat moves back and forth on the chair and the backrest tilts. The chair retains its normal function as long as the back is not extensively tilted. If the coupling can be completely decoupled and the back tills without the seal moving, the chair behaves like a normal chair.
