The seat incorporates devices which force at least one point of the seat surface (1) to move continuously and cyclically periodically in at least two movement directions, whereby the one period is greater, preferably twice as great, as the other period. The seat surface is movable around a variable rotary point (3). The seat surface in its angle of inclination is movable both in the seat direction and also laterally. Leg supports are movable with the seat surface and incorporate at least one lower leg support, preferably with a lateral support surface. |
