FAQ
- Which Aeron size should I buy?
- Size A is rated to 300 lb (~16.4" seat depth), B to 350 lb (~17"), and C to 400 lb (~18.9"). When in doubt between B and C, prioritize seat depth and hip width over height alone.
- Classic or Remastered Aeron?
- Remastered (2016+) brings 8Z Pellicle, PostureFit SL, Harmonic 2, and expanded capacity by size. Classic generally topped out around 300 lb. Used listings mix generations—check tilt and lumbar design.
- Does the Aeron have a factory headrest?
- No. Aeron headrests are aftermarket-only on typical configs.
