Herman Miller Aeron vs M18 Ergonomic Office Chair

Buy the Aeron if you want a proven long-life task chair with a 12-year warranty, breathable suspension and a size range that fits most bodies. Buy the Sihoo M18 if you want a headrest, a deeper recline and adjustable lumbar for long gaming or reclining sessions at a lower outlay. The Aeron has the stronger build reputation and resale value; the Sihoo adds features the Aeron lacks and owners rate its comfort and assembly highly.

• Choose the Herman Miller Aeron if you sit at a desk for hours and want a durable, warranty-backed chair with suspension seating that stays cool.
• Choose the Sihoo M18 if you want a headrest, a 126° recline and adjustable lumbar support for gaming, movies and long work sessions.
