The Muvman (below) is a very different seating device by Aeris, the German manufacturer of active seating that brought you the Swopper(above). The idea behind the height-adjustable Muvman stool/chair/leaning device is that it positions you somewhere between standing and sitting; this keeps your legs active and reportedly encourages you not to hunch your back, which I've found can be a problem with even the best office chairs.

It's difficult to convey the range of motion this chair has by looking at still shots, so click over and check out their animated GIF.
