Released to the market in 1963, the Eames Tandem Seating Group was an extension to the already popular commercial seating options for the Fiberglass Arm and Side Chairs. It was an ingenious system designed for semi permanent installation into all kinds of commercial areas, from schools to lobbies, waiting rooms, surgeries to launderettes.
Following the huge success of the Eames Fiberglass Chairs, especially with the commercially minded stacking variants, this was a new and adaptable system with the idea that it could be safely installed into public spaces. In order to do this it would need to be able to take the rigors of heavy use and be built to deter theft. The solution ticked all those boxes, with a solid steel frame and polished Alu feet, the Eames Tandem Seating Group managed to be heavy duty enough for them not to be easily moved yet maintain a pleasant physical appearance.
The system was designed to have from 3 to 5 places on the frame. Using specially adapted 'spider' connectors it meant that any shell chair (arm or side, standard or La Fonda) could be utilized giving infinite possibilities of colors and setups specific to its application. Especially for the system was also developed a Tandem Table, a small white side table built to use the spider connector and which could also be used on any of the tandem places.
The Eames Tandem Seating series was a commercial success and their availability remained constant until the fiberglass chairs were discontinued in 1989.
The Tandem Shell Series was available with either Fiberglass Arm or Side Eames shells in both standard or La Fonda variants. Due to this the sheer number of specification possibilities was high. The below excerpt page from the 1964 Herman Miller Catalog perfectly demonstrates the series specs:
