The main causes of chronic strain

The dangers of prolonged poor posture.

Poor posture is one of the main causes of chronic strain. You may be accustomed to slouching or sitting in an improper posture for long periods of time, which can cause a variety of physical problems. Here are some authoritative research data:
- The incidence of arthritis among people who sit for long periods of time is as high as 10.2% (source: Journal of Orthopaedic & Sports Physical Therapy).
- Prolonged sitting and lack of exercise among adolescents significantly increase the risk of depression (Source: 2020 prospective cohort study in The Lancet Psychiatry).
- Spinal disorders have become a global health concern, severely impacting quality of life and health levels (Source: World Health Organization statistics).
These data indicate that prolonged poor posture not only leads to joint and spinal issues but may also affect mental health. You need to recognize that adjusting your posture is the first step in preventing chronic strain injuries.

The impact of repetitive motions on the body.

Repetitive motions are also a major cause of chronic strain injuries. You may perform similar actions daily, such as typing, using a mouse, or looking down at your phone. These actions place excessive strain on specific areas, leading to muscle fatigue and joint damage. The shoulders, wrists, and neck are the most commonly affected regions. Over time, you may experience soreness, stiffness, or even develop more severe strain issues. By reducing the frequency of repetitive motions or using ergonomic equipment, you can effectively mitigate these risks.

Limitations of traditional office chairs.

Traditional office chairs have simple designs and lack ergonomic support. You may find that they do not provide sufficient lumbar and back support, leading to unstable posture. The height and angle of the chair are typically non-adjustable, making it difficult to accommodate different body types and needs. These design flaws can cause fatigue after prolonged use and may exacerbate chronic strain issues. Choosing an ergonomic office chair can help improve your posture and reduce physical strain.

Welax S9's core ergonomic technology

📢One-touch precision control: the convenience of a wired control base
The Welax S9 features a one-touch wired control base design, allowing you to easily adjust multiple functions. With a single lever, you can quickly adjust the seat cushion's forward/backward movement, the backrest's tilt angle, and the seat height.
- Seat cushion forward/backward sliding: 8-step locking design to accommodate different heights and body types, ensuring adequate support for the thighs.
- Backrest tilt adjustment: Supports three angle lock positions (105°, 116°, and 130°) to suit various scenarios such as office work, meetings, and leisure.
- Seat height adjustment: Wide range of up/down adjustment to accommodate different desk heights and facilitate storage.
This “one-lever control” design eliminates the complex multi-lever operation of traditional office chairs, making adjustments more efficient and convenient. Whether working or resting, you can quickly find the most comfortable sitting position.


📢6D armrest design: comprehensive support and adjustment
The Welax S9's 6D armrest design provides comprehensive support and adjustment functionality. The armrests can be adjusted up/down, forward/backward, and inward/outward, and also support horizontal and vertical rotation.
- Multi-angle adjustment: The armrests can rotate 360° continuously, always aligning with the natural posture of your arms to reduce pressure on your shoulders and elbows.
- Three-step quick flip: Angle adjustments of 15°, 30°, and 45° accommodate different scenarios such as work, meetings, and leisure.
- Wide height adjustment range: The armrest height can be freely adjusted between 19.5 cm and 26 cm, suitable for different heights and desk heights.
This design not only enhances comfort but also provides optimal support in various scenarios. According to ergonomic testing, a similar 6D armrest design provides ideal support angles for sitting upright while working, taking a midday nap, or lying down to play games, significantly reducing pressure on the shoulder and elbow joints.

📢Dynamic lumbar support and backrest: Scientific zoned support
The Welax S9's dynamic lumbar support and backrest design focuses on providing scientific zoned support for your spine. The lumbar support features a 3D curved design that adapts to the natural curvature of the lumbar spine, reducing the feeling of suspension.
- Dynamic adaptation: Upon sitting down, the lumbar support automatically adjusts to your body shape, ensuring adequate support for the waist.
- Segmented Pressure Distribution: The upper and lower segmented elastic structure supports the thoracic vertebrae above and the sacrum below, evenly distributing lumbar pressure to prevent fatigue from prolonged sitting.
- Backrest Adjustment: The backrest offers a 3.5cm height adjustment range and 5-step locking positions, precisely accommodating users between 150cm and 190cm in height.
User feedback indicates that the dynamic lumbar support and zoned backrest design effectively alleviate lumbar pressure, avoiding issues of insufficient or excessive support. Similar designs are highly regarded in the field of ergonomic office chairs, helping you maintain the natural curve of the spine and reduce the risk of chronic strain.

📢High-quality materials and craftsmanship: safety and comfort combined
Welax S9's design not only prioritizes ergonomics but also pursues excellence in materials and craftsmanship. You might be wondering how this chair balances safety and comfort? The answer lies in its high-quality materials and craftsmanship.

📢German-imported velvet fabric: breathable and skin-friendly
The Welax office chair S9 uses German-imported velvet fabric with 3D oxygen-permeable channels. This material gives the chair excellent breathability, so you won't feel stuffy even after sitting for a long time. Additionally, the velvet's skin-friendly texture provides a soft and comfortable feel upon contact. Whether in the heat of summer or the cold of winter, this material offers an optimal user experience.  

📢Aluminum alloy base corners: ensuring strength and stability  
The chair's base corners are made from high-strength aluminum alloy, which evenly distributes pressure in all directions. Compared to traditional plastic base corners, aluminum alloy is not only more durable but also maintains structural stability over time, preventing deformation. You can use it with confidence, without worrying about deformation or damage due to prolonged weight bearing.

📢SGS Level 4 Explosion-Proof Gas Spring: Enhanced Safety
The office chair S9 is equipped with an SGS-certified Level 4 explosion-proof gas spring. This gas spring has passed rigorous pressure tests, capable of withstanding higher pressures and eliminating the risk of “gas spring failure.” Whether for daily office use or leisure activities, this design provides enhanced safety assurance.

📢Silent nylon casters: Protect floors and move quietly
The chair's casters are made of 65PU nylon material with silent properties. When moving the chair at night, you won't disturb family members or pets. Additionally, these casters offer stronger protection for floors, making them particularly suitable for high-end wooden floors or tile surfaces. They glide smoothly without any jerks, allowing you to feel the attention to detail in use.
