One of the leaders of the Vienna secession, Adolf Loos, was known for his functional, austere interpretation of the style. Loos was a pioneering modern architect and his Steiner House and Goldman & Salatsch Building caused much controversy in Vienna when they were built. Our Loos chair features, as standard, a stainless steel back support and nailheads, which adorn the outside back seat in the form of a rectangle and the top of the front legs. The nailheads at outside back are required.
