The Barcelona chair's polished chrome structure is hand-buffed and hand-finished to a mirror finish. The Spinneybeck leather cushions are upholstered with 40 individual panels cut, hand-welted and hand-tufted from a single hide. Seat and back cushions adapt to fit the curve of the frame. Side and edges of upholstery straps are dyed to match specified upholstery colour.

The KnollStudio logo and the signature of Mies van der Rohe are stamped into the base of each chair.

The Barcelona chair is also available in the Kid version.

Exclusive manufacturing and sales rights were accorded to Knoll by the designer in 1953.
