The Aeron chair didn't end up in the Museum of Modern Art's permanent collection just because it looks cool. Although it does. Its looks are only the beginning. Aeron accommodates both the sitter and the environment. Created by Don Chadwick and Bill Stumpf in 1994, it adapts naturally to virtually every body, and it's 94% recyclable. Even if it's black, it's green. This model is 'middle of the range', size B with adjustable lumbar support, adjustable and pivoting leather armpads, forward tilt and tilt limiter, graphite base and graphite pellicle engineered mesh, and castors for carpet floors.
