Benefits of technology

[0012]It is therefore an object of the present invention to provide an active dynamic seating device such that the possible applications thereof for balance exercises are improved.

Problems solved by technology

In virtually all cases, this active dynamic sitting posture is attained in that the actual seat of the seating device swings about at least one lower pivot and is thus held in an unstable position.
Due to the lack of stabilization, such a balancing exercise can meet with unsteadiness in many people so that the exercise fails.

Embodiment Construction

[0034]FIG. 1 shows a rocking stool as seating device 1. The rocking stool comprises a base part 2, which centrally accommodates a central column 3, on which a seat 4 is fastened. The base part 2 is formed by a circular base plate 2a having a diameter of 400 mm and a convex support surface 2b, wherein the radius of curvature of the support surface is 725 mm. In the known manner, the central column 3 comprises a gas spring for height adjustment, as it is known for office chairs, which allows height adjustment of the seat in the range of 540-740 mm. The height adjustment can be brought about manually by means of a trigger 6. The seat is cushioned slightly, wherein the seat cover encompasses only small to medium grip in order to facilitate gymnastics exercises.
