The Chippensteel 0.5
In fact, this chair is made with exactly the same production technique called FiDU as his Plopp Stool. FiDU is an abbreviation for German “FreieInnenDruckUmformung” – the Internal Pressure Forming. It means that two shapes cut from steel sheets are welded around their edges and inflated into a 3d object under high pressure. I really like the simplicity of this technique and Oskar seems to push its boundaries to the limit, however I’ve yet to see an interior designer incorporate both the Chippensteel and the Plopp into a room properly.
