Sitting for long periods on an office chair with improper posture can easily lead to issues like back pain, neck problems, and spinal disorders. A chair that is ergonomic and correctly adjusted can effectively reduce fatigue and prevent occupational diseases.

Here are the correct adjustment methods for office chairs
1.Seat Height
When sitting, your feet should be flat on the floor, with your thighs parallel to the ground and knees at a 90-degree angle. If the chair is too high, you can place a footrest under your feet.
2.Seat Depth
Your hips should be firmly against the backrest, leaving a 2-3 finger-width gap between the back of your knees and the edge of the seat. If the seat is too deep, place a cushion at your lower back.
3.Backrest Height
The backrest should support your lower back, maintaining the natural curve of your spine. If the backrest is too high or too low, adjust the height of the backrest or use lumbar support.
4.Armrest Height:
The armrests should allow your arms to hang naturally, with elbows at a 90-degree angle and shoulders relaxed. If the armrests are too high or too low, adjust the armrest height or remove the armrests.
5.Headrest Height
The headrest should support your head and maintain the natural curve of your neck. If the headrest is too high or too low, adjust the height of the headrest or remove it.
6.Backrest Recline Angle
The backrest can be slightly reclined to maintain a comfortable sitting posture. If the recline angle is too large, adjust the angle or use lumbar support.
7.Lumbar Support
If the chair does not have lumbar support, you can use a cushion to support your lower back and maintain the natural curve of your spine.
8.Regular Movement
Even with correct posture, it’s important to stand up and move around periodically, stretching your body to avoid health issues caused by prolonged sitting.
By properly adjusting your office chair using the above methods, you can effectively relieve back pain and create a healthy and comfortable work environment.
