The Barcelona chair is a perfect design and strong visual statement. It has become the ultimate and timeless image of elegance and comfort. A careful study of the potential for even softer upholstery and a new collection of 'full grain' leathers, softer to the touch and capable of ageing gracefully have contributed to give a more relaxing feel to what remains the undisputed 'monument' of the international history of design. Exclusive manufacturing and sales rights were accorded to Knoll by the designer in 1953. The KnollStudio logo and the signature of Mies van der Rohe are stamped into the base of each chair.
