This chair seems to be an excellent replica of the 'BRNO' cantilever armchair designed by Ludwig Mies van der Rohe and Lilly Reich for Knoll. The chair features a polished chrome steel structure with a seating upholstered in synthetic cream leather. 

Good used condition. There are some scratches, stains and traces of use on the synthetic leather (see images). A bit dusty, needs to be cleaned.
