EA105 Aluminum Group side chair, Chares Eames, 1958.

The chairs in the Aluminium Group are the most famous creations by Charles and Ray Eames. Designed in 1958 they rate amongst the great achievements in the design history of the 20th century. An important characteristic of the Aluminium Chair is the intelligent combination of materials. It has a clear, transparent form and its construction is clearly visible. Aluminium sections lend the chair both stability and lightness. The material is fixed into the side sections, yet fitted loosely so that it follows the line of the body and is comfortable without requiring extensive upholstery. This material is not a cover but an integral part of the design.

Known during its development as the Leisure Group or Indoor-Outdoor Group, the Aluminum Group currently comprises of high-back, tilt-swivel lounge chair, a low and high-back, tilt swivel desk chair with an adjustable seat and a low-back side chair (all with or without arms) as well as an ottoman, a coffee table and a dining table available with a variety of tops. Originally intended for domestic retail, the group was eventually marketed for contract use.
