With this design, Charles and Ray Eames reduced the elements of the chair to two distinctly expressed components. The seat and back are one element, moulded together in a bucket shape familiar from other chairs by the Eames. The exterior shell is structural and stiff, but is lined with soft upholstery for comfort. Both the metal pedestal base and the fibreglass shell of the seat are painted white to give the illusion that they are made of one material. In a sense the only unnecessary aspect of the design is that the pedestal upright has been divided into four rods where a single thicker column would have sufficed. However, the cluster of rods has the effect of lessening the visual impact of the chair base by allowing light and air through it.
