“How light and slender can a chair be and still maintain its strength?” That was the question that led to the 20-06 Stool (2006), designed by architects Foster & Partners for the Smithsonian. Weighing just 7 lbs., this stool is crafted out of 80% recycled aluminum and has a tensile strength three times that of steel. It takes 77 steps to create this hand-welded seamless stool but the result is an estimated 150-year life span – longevity that means less impact on the earth's resources. Made in U.S.A.
