 According to a 2010 "Bloomberg Businessweek" article, the Aeron chair "made a fetish of lumbar support".Galen Kranz has commented that while the company is aware that a perching position (facilitated by the chair's rounded front rail) is preferable, it put in the lumbar support to conform to public expectations—"because that's what people think is required for it to be a scientifically 'good' chair".Sitting expert A. C. Mandal has criticized the Aeron as "far too low" and not offering enough height adjustment and opportunities for the sitter to move.
