Zeta cantilever chair in very good condition, with dark brown, almost black aniline leather. Heavy stainless steel frame in Z-shape. The design is reminiscent of the Barcelona Chair by Mies van der Rohe for Knoll. However, this chair was designed by Paul Tuttle and manufactured by Strässle International / WK Wohnen in the 1970s.See photos, very good condition with few signs of wear due to age.
