The Chippensteel 0.5 is a chair designed by Oskar Zieta. This chair is made with exactly the same production technique called FiDU as his stool Plopp. 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.
