Aeron vs Generation by Knoll: the practical decision
Start with fit: compare the exact Aeron size with the Generation seat-depth setting. If you frequently turn or sit sideways, assess whether Generation's flexible back suits that habit. Neither specification establishes a universal comfort winner.
This is a research-based comparison, not a hands-on test. No comparative rating, fixed price gap or durability ranking has been established here.
