Verdict: The Herman Miller Aeron Chair outperforms the Autonomous Ergochair 2 with better build quality, size options, and longevity according to RTINGS and Wirecutter reviews. The Ergochair 2 provides solid basic features at $270 MSRP but lacks the Aeron's proven durability and repair ecosystem. Aeron wins for users prioritizing long-term ergonomics over initial savings.
Our take: The Aeron's pellicle seat feels taut and supportive under prolonged sitting while the Ergochair's foam can bottom out after a few hours. Adjusting the Aeron's PostureFit pads gives a more precise lower-back fit than the Ergochair's sliding lumbar pad. Daily users notice the Aeron's smoother recline and quieter mechanisms compared to the Ergochair's occasional creaks.
Winner: Herman Miller Aeron Chair
Autonomous Ergochair 2: 5.5/10
Herman Miller Aeron Chair: 8.5/10

Our pick: Herman Miller Aeron Chair. It edges out the alternative on posturefit sl lumbar support standard. That said, Autonomous Ergochair 2 still wins on adjustable lumbar support, headrest, armrests, seat height and tilt — consider it if that single trade matters most for your use.
