The Science of Comfort: What Makes the Sihoo Doro C Series Unique?
Ergonomics isn’t just about comfort – it’s about long-term health. The Sihoo Doro C Series, particularly the Sihoo Doro C300 Pro, is engineered to support the body’s natural posture, preventing the common aches and pains associated with prolonged sitting. Sihoo has integrated cutting-edge science into the design in the following ways:
1. Self-adaptive dynamic lumbar support
One of the biggest challenges of sitting for long hours is maintaining proper spinal alignment. The Sihoo Doro C300 and Sihoo Doro C300 Pro feature an innovative Body Movement Tracking (BM) System, which automatically adjusts lumbar support as you move. This ensures constant lower back support, reducing strain and discomfort, without requiring manual adjustments.
2. Multi-adjustable armrests for personalized support
Unlike standard office chairs, the Sihoo Doro C300 Pro offers 6D coordinated armrests, allowing users to adjust height, depth, and angle. They’re not just adjustable in multiple directions – they also synchronize with the backrest when you recline, keeping your arms supported in all positions. This feature is particularly beneficial for gamers and professionals who require adaptable positioning to reduce wrist and shoulder fatigue.
3. Waterfall-shaped seat cushion & seat depth adjustment
A poorly designed seat cushion can lead to circulation issues and discomfort. Sihoo tackles this problem with a waterfall-shaped seat cushion, which promotes healthy blood flow and relieves pressure on the thighs. Additionally, the Sihoo Doro C300 Pro includes seat depth adjustment, accommodating users of various heights for a truly customized seating experience. The height and recline angle can be seamlessly adjusted using the conveniently positioned handle on your right side, allowing you to effortlessly control your chair with just one hand, without the need to reach down.
4. Adaptive reclining & smart weight-sensing mechanism
The Sihoo Doro C300 Pro is built for both productivity and relaxation. Its adaptive reclining mechanism allows users to switch between an upright working position and a comfortable recline up to 135°. Combined with a smart weight-sensing chassis, the chair automatically adjusts resistance based on the user’s weight, ensuring effortless movement and balance.

5. Breathable mesh design for all-day comfort
Overheating and discomfort are common issues with traditional office chairs. The Sihoo Doro C Series features a high-elastic, breathable mesh, which not only provides superior airflow, but also maintains its shape and elasticity over time. This ensures lasting support without the heat buildup of standard foam cushions.
