Mies van der Rohe’s MR chairs were designed in 1927 for the Weissenholf housing development project along with Mart Stam’s cantilever chair. The chair uses a small gauge tubular steel frame that retained a certain amount spring providing extra added comfort to the clean design. The chairs are part of the MR series of seating that exhibit Mies van der Rohe’s first use of bent tubular steel in its design. It is a marvelous example of Mies’ use of a single closed structural line.
