What Makes a Good Chair?
We've been asking ourselves the same question for over a decade: What makes a chair truly exceptional? How can we scientifically measure comfort and support?
At Sihoo, we believe the answer lies in understanding how your body interacts with your chair throughout the day. That's why we established the Sihoo Ergonomics Research Institute in partnership with leading biomechanics experts, creating a comprehensive approach to seating science.
Our research centres combine:
- Advanced biomechanical testing laboratories
- Real-world user experience studies
- Innovative seating technology development
- Continuous comfort optimisation systems

Posture & Seating - The Foundation of Health
Sitting is one of our most natural postures. It conserves energy, reduces muscle fatigue, and provides the stability needed for precise, detailed work. From writing to designing, coding to creating—sitting enables us to perform complex tasks with greater control and accuracy.
However, this seemingly simple position comes with hidden challenges. Poor sitting posture over extended periods can lead to:
- Lumbar muscle strain and chronic lower back pain
- Spinal degeneration and disc problems
- Reduced blood circulation and cardiovascular issues
- Neck and shoulder tension
- Decreased productivity and mental fatigue
Optimal Weight Distribution
Your chair should distribute your body weight evenly across multiple contact points, preventing pressure build-up in any single area. This means your spine, hips, and thighs share the load naturally, allowing your muscles to relax rather than constantly working to maintain position.
Natural Thigh Positioning
The ideal seated position maintains your thighs approximately horizontal, with your feet resting naturally on the floor. This position ensures:
- Proper blood flow to your lower extremities
- Reduced pressure on the underside of your thighs
- Better overall stability and comfort
- Less strain on your hip flexors and lower back
Multi-Dimensional Support
Your body needs support in multiple planes:
- Lumbar support for your lower back's natural curve
- Thoracic support for your upper back alignment
- Pelvic support to maintain proper hip position
- Arm support to reduce shoulder and neck strain
This comprehensive support system creates a stable platform for work while preventing the micro-movements that lead to fatigue.
Dynamic Flexibility
Static sitting is the enemy of health. A good chair must facilitate easy transitions between different working postures:
- Smooth recline for thinking and reading
- Forward tilt for intensive desk work
- Side rotation for collaborative discussions
- Quick adjustments without disrupting workflow
Our Unique SPM Development System
We've developed the industry's first comprehensive SPM (Subjective-Physiological-Motion) feedback system to create chairs that truly work for you:

Leading ergonomic innovation with over 100 researchers, designers, and engineers dedicated to perfecting your seating experience
Pioneering Technology
At Sihoo, we focus on developing breakthrough technologies that transform how people experience comfort. Our research spans long-term ergonomic solutions, forward-thinking design concepts, and revolutionary products that elevate quality of life.
Our innovations are integrated across our entire product range, ensuring every Sihoo chair benefits from our cutting-edge research and development.
The Space Base™ - The Heart of Ergonomic Excellence
Borrowing from aerospace engineering, we've introduced aviation-grade glass fibre technology—a material typically found in rocket shells and helicopter rotors—into office seating. This revolutionary material has passed 300,000 fatigue cycle tests, ensuring decades of reliable performance.
Our Space Base mechanism delivers linear force feedback that automatically adapts to your body weight, achieving 99% precision in recline tension adjustment. Whether you weigh 50kg or 120kg, you'll experience the same effortless "lean back easily, rise without strain" sensation. The synchronised seat-back movement ensures the seat edge never lifts uncomfortably when reclining, eliminating common problems like thigh pressure and lumbar gaps found in conventional chairs.
Domino Dynamic Lumbar System™
Our groundbreaking Domino system creates an entirely new approach to back support. Unlike traditional fixed or split backrests that leave gaps at crucial support points, this system integrates three-dimensional adjustment modules—horizontal, vertical, and depth—into one intelligent lumbar unit.
Working in harmony with the seat, backrest, and your body, the system creates a chain reaction of support that follows your every move. Whether sitting upright or reclining, the lumbar support responds like falling dominoes, continuously adapting its pressure and position to maintain perfect spinal alignment.
6D Bionic Armrest Technology
As the industry's most versatile armrest system, our 6D Bionic technology doubles the adjustability of conventional armrests. Beyond standard up-down, forward-back, and horizontal rotation, we've added inward-outward adjustment, vertical pivot, and synchronised tilt functions.
This biomimetic design mirrors the natural movement of human arms, supporting every working position—from intensive typing to relaxed reading, collaborative discussions to focused analysis. Your arms find perfect support no matter how you work.
Adaptive Dynamic Lumbar Technology
Inspired by the natural curve of the human spine, our dynamic lumbar system features the industry's first 6D auto-morphing support mechanism. It adjusts in all directions—up, down, left, right, forward, and backward—creating a personalised embrace for every user.
Equipped with automotive-grade actuators supporting 90-105 degree adjustment ranges, the system delivers precise support regardless of your posture or body type, ensuring your lower back receives optimal support throughout your workday.
