The design of the Aeron chair did more than just
fulfill the design criteria. It did not look like or behave like
any office chair ever designed before.
Chadwick and Stumpf designed one chair, available in three sizes
to fit everybody from the 1st-percentile (female) to the
99th-percentile (male). The B size chair is designed for
the largest group of people on a Gaussian Chart, the 50th-percentile
or the mean. The A-size chair, which adjusts lower
than the other two are designed for smaller people and the C-size
chair with the larger size seat and backrest is designed for larger
The majority of the Aeron Chair is made of recycled materials
and is designed to last a long time. The parts that get the most
wear are easily replaced and recycled.
The designers deliberately tried to make their chair look different
than any other type of office chair on the market. If you examine
the chair you will notice that it contains no straight lines.
The designers have pointed out that the human form has no straight
lines it is biomorphic. Their intentions were to create a chair
that was also totally biomorphic.
