SIHOO Doro S100 Ergonomic Office Chair – A Chair That Solves Problems

True comfort lies in adaptive support. The SIHOO Doro S100 isn’t just a seat—it’s an intelligent system designed for those who work, game, and create. Whether you're deep in remote work, leading a raid in your gaming room, or serving users in a cyber cafe, this chair moves with you. Its 4D armrests adjust up and down 7cm, forward and back 3cm, pivot 72° inward/outward, and sync with recline. The 3D auto-adaptive headrest provides multi-angle support, while the dual dynamic lumbar system with 4-spring mechanism offers 6D automatic shaping to fit any body type. Recline smoothly with intelligent tilt, and rest assured with BIFMA and SGS certifications. Because a chair that doesn’t solve problems isn’t a good chair.

1. 4D Synced Armrests

   Ultra-soft 4D armrests adjust in height (7cm), depth (3cm), angle (72°), and sync with recline—ideal for prolonged use in your ergonomic chair during work or gaming.

2. 3D Auto-Adaptive Headrest

   This computer chair’s headrest moves vertically, horizontally, and angularly to support your head and neck in any posture.

3. Dual Dynamic Lumbar Support

   Featuring dual wings and 4 springs, the office chair’s lumbar system automatically contours to your spine’s shape, offering 6D wrapping support.

4. Pressure-Relief Seat Design

   The waterfall-style seat cushion with 5cm depth adjustment maximizes contact area, reduces pressure on thighs and hips, and promotes blood flow.
