Sihoo Anti-Gravity Mechanism: Revolutionizing Comfort with 130° Reclining Angle and Aerospace Materials

The Sihoo anti-gravity mechanism Development Story

According to research from health and medical institutions, people in modern society spend an average of 9.3 hours per day sitting in office chairs. Well-designed and comfortable chairs not only provide proper support for body weight but also ensure sufficient comfort. The chair's structure plays a crucial role, with the mechanism being of utmost importance.

I. Importance of the mechanism

The Sixth Generation anti-gravity mechanism Leads in Technology

Sihoo's anti-gravity mechanism has been at the pinnacle of comfortable chair technology for nearly 30 years. The mechanism, often referred to as the heart of ergonomic chairs, is comparable to the engine of cars and rockets, representing the Everest of chair technology. It integrates functions such as overall adjustment knobs, reclining angle control, and linked support force control, ultimately influencing the chair's comfort. The quality of a chair is fundamentally determined by its mechanism.

According to Branton's "Posture Balance Theory," even if a chair is comfortable and theoretically reasonable, sitting for extended periods can lead to discomfort. This is where dynamic support becomes crucial. The mechanism is key to achieving better adaptation of the chair back to the curvature of the spine and dynamic support required for various body movements.

II. Current State of mechanism Technology

In the over 100-year history of ergonomic chairs, mechanism technology has evolved from fixed mechanism to the latest fiberglass mechanism, representing five generations of iterative updates. Each leap in mechanism technology is closely tied to breakthroughs in fundamental sciences such as ergonomics, materials science, and biomechanics.

First Generation Fixed mechanism: Basic and low-tech, mainly used for fixed support and cushion adjustment in ordinary chairs.

Second Generation Single Torsion Spring mechanism: Limited functionality, used in lower-priced ergonomic chairs.

Third Generation Single Coil Spring mechanism: Improved features compared to the previous generations but with uneven resistance during reclining.

Fourth Generation Double Coil Spring mechanism: Upgraded version with some independent design for better comfort.

Fifth Generation Traditional Double Fiberglass mechanism (Small Reclining Angle): Independent design and development, addressing issues of uneven resistance. However, limited by technology, the reclining angle is small.

Sixth Generation anti-gravity mechanism (Large Reclining Angle): Sihoo's breakthrough with a nearly flat 145° reclining angle, using high-performance glass fiber material and a four-bar linkage structure for superior comfort and support.

III. Sihoo's Innovative anti-gravity mechanism

The double fiberglass spring mechanism represents the current peak of mechanism technology. However, this technology has long been monopolized by countries like the United States and Japan, leading to Sihoo's confinement to the low-end market. The introduction of the Sihoo Doro S300 with the large anti-gravity mechanism has garnered significant attention from the industry.

Five Breakthroughs of Sihoo's anti-gravity mechanism:

1.Angle Breakthrough: 145° Large Reclining Angle for Health and Comfort
Achieving a large reclining angle with double fiberglass springs is a significant challenge. Sihoo's anti-gravity mechanism breaks through the traditional limitations, offering a nearly flat 145° reclining angle, setting a world-leading standard.

2.Material Breakthrough: Creative Use of Aerospace Materials
Considering the diverse sitting postures of individuals and the frequent use of reclining, Sihoo's research team drew inspiration from aerospace vehicles. They introduced a special high-performance glass fiber material, meeting the requirements of aerospace applications and forming a new generation fiberglass spring base material.

3.Mechanical Breakthrough: Balanced Elasticity
Overcoming the limitations of uneven elasticity, fatigue, and poor durability inherent in traditional spring materials, Sihoo's aerospace fiberglass springs maintain balanced elasticity through 300,000 durability tests.

4.Structural Breakthrough: Four-Bar Linkage Mechanism for Coordinated Movement
According to research, a reasonable incline of the chair seat can reduce the stretching of the back and leg muscles, ensuring even pressure distribution. Sihoo's innovation with a four-bar linkage mechanism allows the chair back to move in coordination with the user's body during reclining, providing dynamic support and relieving fatigue from prolonged sitting.

5.Comfort Breakthrough: Floating Sensation for Healthy Support
Enhancing chair comfort is a crucial goal for each generation of mechanism. Sihoo's large anti-gravity mechanism, through aerospace fiberglass springs and a four-bar linkage structure, thoroughly addresses the fundamental issues of traditional spring-based mechanism. Users can adjust the optimal softness according to their body weight, achieving a floating sensation at any angle, resembling a zero-gravity back pressure experience, ensuring long periods of sitting without fatigue or discomfort.
