We claim: 1. A seating device comprising: a base; means for supporting an upper body of a person, wherein said means for supporting is connected to said base; driving means connected to said base; a seating surface connected to said driving means; said driving means driving said seating surface so that at least one point of said seating surface is forced to perform a periodic, continuous and cyclical movement in at least two directions of motion, wherein said periodic, continuous and cyclical movement comprises a first period of motion and a second period of motion, wherein a number of said first period of motion is larger than a number of said second period of motion; wherein said seating surface is not directly connected to said means for supporting and moves independently of said means for supporting and independently of said base. 2. A seating device as in claim 1 wherein said means for supporting the upper body comprise at least one supporting device resiliently mounted thereto. 3. A seating device as in claim 2 wherein said at least one supporting device is displaceable over a guide on a concave motion path relative to said base independently of said seating surface. 4. A seating device as in claim 3 wherein said at least one supporting device comprises a back support. 5. A seating device as in claim 3 wherein said at least one supporting device comprises a stomach support. 6. A seating device as in claim 3 wherein said at least one supporting device comprises a headrest. 7. A seating device as in claim 3 wherein said at least one supporting device comprises a neck-rest. 8. A seating device as in claim 3 wherein said at least one supporting device comprises a shoulder-rest. 9. A seating device as in claim 3 wherein said at least one supporting device comprises a lumbar support. 10. A seating device as in claim 2 wherein said at least one supporting device comprises at least one lateral support supporting the upper body under the armpits. 11. A seating device as in claim 2 wherein said at least one supporting device comprises a chin-support. 12. A seating device as in claim 1 further including at least one arm support resiliently connected to said base and comprising at least one forearm support that is resiliently displaceable in at least a horizontal direction. 13. A seating device as in claim 12 wherein said resilient arm support comprises a suspended mount mechanism. 14. A seating device as in claim 13 wherein said arm support further includes a lock. 15. A seating device as in claim 1 further including at least one lower leg support having a footrest, wherein said lower leg support is connected to said seating surface by a mounting device and is connected to said base. 16. A seating device as in claim 1 further including at least one leg-rest/footrest connected to said base, wherein said leg-rest/footrest is movable relative to said base and relative to said seating surface and is lockably mounted on said base at an angled position by a rod or mounting plates or guides. 17. A seating device as in claim 1 wherein said number of said first period of motion is chosen to be twice as large as said number of said second period of motion. 18. A seating device as in claim 17 wherein said at least one point of said seating surface is shifted about a center of motion that is alterable. 19. A seating device as in claim 18 wherein said center of motion is altered depending on a displacement of said seating surface about said center of motion. 20. A seating device as in claim 19 wherein an angle of inclination of said seating surface is displaceable in a sitting direction and laterally. 21. A seating device as in claim 20 wherein said seating surface is displaceable in a forward direction, in a backward direction and laterally.
