Demon King Style Office Chair

Here are the correct usage methods for the Demon King Style Office Chair (such as the Bull Demon King Love Chair and other ergonomic chairs):

1. Basic Height Adjustment

• Seat Height: Adjust the seat height so that your feet rest naturally flat on the ground, with your thighs parallel to the ground and your knees bent at a 90-degree angle. Your elbows should hang naturally, and the desktop height should be level with your elbows to ensure that your arms are not left hanging or your shoulders are not raised when placed on the desk.
• Applicable Scenarios: This adjustment helps avoid leg compression or shoulder and neck fatigue caused by improper height, making it suitable for long hours of office work or study.

2. Backrest and Support Component Adjustment

• Backrest Angle: Adjust the tilt angle according to your body shape so that the backrest fits the curve of your back, providing even support.
• Lumbar Support Function: If equipped with lumbar support, align it with the natural curve of your lower back (approximately at the third to fourth lumbar vertebrae position) to avoid a hollow lower back and reduce lumbar pressure.
• Headrest Height: Adjust the headrest height to align with your cervical spine, allowing your neck to fully relax when your head naturally leans back, preventing excessive forward or backward extension of the cervical spine.

3. Armrest Adaptation Adjustment

• Height Matching: The height of the armrests should be level with your elbows to avoid your arms hanging in the air or your shoulders being raised.
• Angle Fine-Tuning: Adjust the front-back and up-down positions of the armrests according to your needs so that your arms naturally rest on the desk at a natural angle, reducing shoulder and wrist pressure.

4. Daily Use and Maintenance

• Material Selection: Prioritize using the original factory's breathable mesh fabric or sponge seat cushion to reduce the feeling of stuffiness during long sitting. During seasonal changes, you can pair it with a suitable seat cushion or blanket.
• Cleaning and Maintenance: Regularly clean the seat cushion with a soft-bristled brush or mild detergent, avoiding the use of corrosive chemicals. Do not place objects weighing more than 50 kilograms on the armrests to prevent structural damage.

5. Healthy Usage Habits

• Regular Breaks: Get up and move around every 30-60 minutes of sitting to avoid muscle stiffness or poor blood circulation caused by maintaining the same posture for a long time.
• Reclining Limitation: Avoid reclining the seat completely for a long time to maintain the natural physiological curve of the spine. When relaxing, you can moderately adjust the backrest angle and use the tilt-lock function to switch between office and rest modes.

6. Regular Inspection and Maintenance

• Structural Inspection: Check the screws and connectors for looseness at regular intervals and tighten them promptly to avoid abnormal noises or structural instability.
• Function Testing: Regularly test whether functions such as height adjustment, tilting, and rotation are working properly to ensure usage safety.
