Abstract: A seating device comprising a connecting element having an end portion dimensioned to be releasably and rotatably inserted into an aperture defined in a ground or floor. The aperture is dimensioned to receive the connecting element so as to support the seating device. The seating device also comprises a supporting element connected to a seat. The supporting element is pivotably connected to the connecting element. Moreover, at least one of the connecting element and supporting element comprises at least one stop so as to permit the supporting element to pivot between a first position whereat the supporting element is in a substantially vertical position, and a second position whereat the supporting element is forwardly inclined of 30 degrees or less with respect to the first position. Such a device is particularly useful for persons who need to stabilize their posture while performing a task.
