The present invention relates to a dynamic seating device with a seat plate (1), which is mounted by means of a bearing head (5) on an under-frame with a height-adjustable column (14) or on a bearing surface. In order to automatically ensure natural movements of the user at the same time with free mobility, according to the invention it is proposed that the seat plate (1) comprises a recess (8) arranged in its centre, becoming larger from its top side towards its lower side, that a bush (19) is passed from below and secured through the recess (8) in the seat plate (1), that the bush (19) rests on the bearing head (5) of a support pin (6), wherein the bearing head (5) is shaped spherically or hemispherically, so that a common rotating and swivelling point arises above the seat plate (1).
