Herman Miller Embody vs Sihoo Doro C300 Ergonomic Office Chair

The Embody is the better-built chair and the safer long-term buy for heavy daily use. Its die-cast aluminum frame, 12-year warranty and pixelated back support are a step above the C300's plastic-and-mesh build. The Doro C300 costs far less, carries a higher weight rating and adds a headrest and 4D arms, and its 4,107 ratings average slightly higher. Buy the Embody for a decade of eight-hour days; buy the C300 if you want more adjustments and a headrest for less.

• Choose the Embody if you sit most of the day, want a 12-year warranty and a frame that will outlast several cheaper chairs.
• Choose the Doro C300 if you want a headrest, 4D arms and a 130° recline, and you weigh close to 300 lbs or want more adjustability for less.
