Amazing Chairs!

These amazing chairs are as mysterious as they are incredibly stylistic. I have a complete set of 4 chairs (only 3 pictured). I've had these chairs for years, but have never know of their origin, manufacturer, or their place in history. They are upholstered in a micro-fiber-like material that is aqua greenish in color, very smooth like velvet. Not sure of the style either, other than very eclectic or art-deco-y. The tag underneath the chair lists a "Registry Number" of CA 30169, but I do not know to what that refers. The frame is made of chromed metal legs and curved back struts. Any help identifying these would be very much appreciated! Thank you!
