Sihoo Doro S100 vs S300: Real-Life Experience Reviewed

Last Updated on October 15, 2025 by Cassie Moorhead

Choosing between the Sihoo Doro S100 vs S300 can feel tricky. I have tried both chairs, and here’s what I found. The S300 has better lumbar support and a smooth recline. The S100 is simpler and costs less but still works well. For long work or gaming sessions, the S300 feels more comfortable. If you are in the USA, both chairs fit standard desks, but the S300 gives extra ergonomic support.

Sihoo Doro S100 Review

The Sihoo Doro S100 is one of the best ergonomic chairs I’ve used this year. It feels solid, smart, and easy to adjust. The dual dynamic lumbar support stands out right away. It moves as you move, keeping your lower back in the right spot all day. I’ve used it for both work and gaming, and it feels supportive either way. If you sit for long hours and want lasting comfort, this chair delivers.

What I Like

• Back support that adapts: The dual dynamic lumbar support adjusts when I lean or twist. My lower back stays relaxed, even after long hours.
  
• Easy to fit any height: I’m 6’3”, and my partner is just over 5’. Both of us fit fine. The independent backrest makes it easy to find the right spot.
  
• Comfortable seat design: The waterfall seat cushion helps reduce leg pressure. It also keeps my thighs from feeling sore after sitting all day.
  
• Cool and breathable mesh: The mesh seat lets air flow through, so it never feels hot or sticky.
  
• Smooth movement: The chair glides quietly on hard floors. The BIFMA and SGS certifications make it feel safe and well built.
  

What Could Be Better

• Seat size: The seat could be wider. Some taller or broader users may want more space.
  
• Lumbar gap for smaller users: If you’re under 5’4”, the lumbar panels may feel a bit wide.
  
• Quality checks: A few online reviews note missing or broken parts. Sihoo could tighten its inspection process.
