Charles and Ray developed this seating shortly after their Eames Molded Plastic Armchair. They figured that if they could first successfully design and produce the more complicated armchair, then relatively speaking, creating the side chair would be easy.
As it turns out, the side chair had its own challenges. The earliest attempts did not stand up to regular use and developed cracks at the point where the back melded into the seat.
The first Eames Molded Plastic Armchairs were displayed and later put on sale in 1950, while the side chairs—reinforced after careful measurement and trial and error—were not introduced until one year later.
The rod-style base holding up this seat makes it the lightest weight Eames chair available today, but it is still as strong and durable as every other chair that Charles and Ray designed.
