Office Chair Shrugging

Shrugging caused by office chairs is mainly related to the mismatch in height between the desk and chair or design flaws in the chair. It can be alleviated by adjusting the height, choosing an adjustable functional chair, and maintaining proper sitting posture.

The height difference between the desk and chair is a core factor

The height difference between the desktop and the seat surface of the chair directly affects the condition of the shoulders and neck. The recommended height difference is 25-30 cm, which should be adjusted according to height:

• For those with a height of 155-165 cm, a height difference of about 25 cm is recommended;
• For those with a height of 165-175 cm, a height difference of 27-28 cm is recommended (covering most adults);
• For those with a height of 175-185 cm, a height difference of 28-30 cm is recommended. If the height difference exceeds 30 cm, a desktop that is too high will force the arms to be raised while working, causing continuous tension in the shoulders and neck. Over the long term, this can easily lead to shoulder and neck strain and stiffness in the trapezius muscles. If the height difference is less than 25 cm, a desktop that is too low will cause the arms to sag and the upper body to lean forward and bend over, leaving the waist unsupported and leading to lower back pain.

Design flaws in office chairs exacerbate the problem

Some so-called ergonomic chairs only have basic height adjustment and a fixed lumbar support. If the height of the armrests cannot match the desktop, shrugging is required to maintain arm posture while typing, further increasing the burden on the shoulders and neck. A truly ergonomic chair needs to have functions such as adjustable armrests, lumbar support, and seat depth to meet the needs of people of different heights and body types. For example, the armrests should be adjustable up and down and forward and backward to ensure that when the elbows are bent at 90 degrees, the upper arms hang naturally and the elbows are slightly lower than the desktop. The lumbar support should be adjustable up and down and forward and backward to fit the curve of the lumbar spine and avoid an unsupported waist.

Targeted relief measures

1. Adjust the height of the desk and chair: Use adjustable desks and chairs to ensure that the height difference is within the recommended range and make fine adjustments according to your height. If the desktop is fixed, you can adjust the height of the chair or use a footrest for assistance.
2. Choose an adjustable office chair: Give priority to purchasing a chair with multi-dimensional adjustment functions. Focus on checking whether the adjustment ranges of the armrests, lumbar support, and seat depth meet your needs.
3. Maintain proper sitting posture: When sitting upright, keep your buttocks close to the back of the chair and your feet flat on the ground. Let your upper arms hang naturally with your elbows bent at 90 degrees and your elbow positions slightly lower than the desktop. Keep your head in a neutral position, look straight ahead or slightly downward, let your shoulders hang naturally and spread backward, and keep your waist close to the back of the chair. Get up and move every 30-60 minutes to avoid staying in the same position for a long time.
