The system is particularly suitable for persons who must remain in seated position over long periods, for instance, persons working in offices and the like. The system comprises one or two support surfaces (2) for the feet of the user, which are moved by a motor-driven base (1). Said support surfaces may perform an alternating longitudinal movement, a lifting and lowering movement or a movement combining the latter two. The support surfaces are moved, for example, by means of connecting rods (5) hingedly connected to said support surfaces in the central point (6) and hingedly connected by their other end to eccentric pivots (9) allocated to respective toothed wheels which are mounted with rotational freedom on their respective axis (8), an intermediate motor-driven pinion (10) that conveys rotational movements in opposite direction to the wheels being placed between said wheels.
