Released in 1957, the 600 Series Draftsman's Stools were a specially adapted design for the Fiberglass chairs intended for the workplace market. The height and versatility of the Eames Draftsman's Arm Chair Stool was ideal for those that required seating for tasks above and beyond the normal desk height and as the name suggests, was perfect for draftsmen, architects, artists and painters.
There were 2 models of the initial release of the Eames Draftsman's Arm Chair Stool, the 622NA with swivel and the 622TA with swivel and full tilt mechanism, much the same as that found on the DAT work chair. Both versions had height adjustment of 2 inches by way of the manual thread on the center column. There was also two corresponding side chair versions the 622NS and 622TS. The chairs were available in a plethora of upholstery choices and each arm model could be bought in 3 different base heights.
The initial release of the stool had a very distinctive 'spider base' not seen on other Eames products, finished in what was called 'crackle' grey enamel and topped with a stainless steel foot ring. The purchaser had the choice of any of the available book shell colors through the years and generations therefore it is possible to find this stool with a huge variety of possibilities.
The base of the Eames Draftsman's Arm Chair Stool was changed in 1966 along with most of the other work place chairs to the Universal Base, essentially giving it the possibility of castors and movement as well as the stationary version it had previously been.
The 600 Series Draftsman's Stools were available in two models, the 622NA swivel stool and the 622TA tilt and swivel stool. Each was available at three varying base heights and in a plethora of upholstery options. This excerpt from a 1963 Herman Miller catalog is the best example explanation of the specifications of these stools.
