Our crush on Oskar Zieta's work continues with the limited-edition Chippensteel 0.5 Chair. These individual works of design are made from welded sheets of steel and inflated like a balloon using high-pressure air by an innovative process called FiDU (Freielnnen Druck Umformung, as in free inner-pressure deformation). The effect is metal frozen in time. No two are alike. The crumples and crushes happen spontaneously as the flats are filled. Because minimal material is needed, the stools are much lighter than they appear. Polish engineer Oskar is took several awards for the original model in the series, the Plopp Stool, and deservedly snared the Red Dot Award for it.
