The invention relates to an adjustable damping system for a vehicle seat for damping vibrations of a seat-part-side upper part relative to a body-side lower part in at least one spatial direction (X, Y, Z), at least one damping element, arranged between the seat-part-side upper part and the body-side lower part and adjustable by an adjustment device, being provided for the damping. The damping system is further distinguished in that at least one relative movement variable and a change in the relative movement variable of the seat-part-side upper part relative to the body-side lower part can be determined by a sensor device, and a first damping force of the damping element can be adjusted by the adjustment device as a function of the at least one relative movement variable and the frequency of the change in the relative movement variable.
