FAQ
Common misunderstandings in the use of office chairs mainly include the following aspects:
1. Misunderstandings in choosing office chairs
There are some common misunderstandings that need to be paid attention to when choosing office chairs.

However, as a company that needs to purchase desks in large quantities, it is easy to overspend when choosing expensive brand-name products. In addition, in some companies, the administrative staff is responsible for the purchase of office chairs. They are not experienced in purchasing office chairs, and they are prone to making some selection misunderstandings.
2. Misunderstandings about using office chairs
There are also some common misunderstandings when using office chairs. For example, some people won’t ask what an upholstered office chair is;
Understand what a soft office chair is. When using office chairs normally, some people will not pay attention to the material of the office chair. They will directly wipe the solid wood office chair legs with a dry cloth and then apply some detergent. However, doing so will accelerate the internal rot of the solid wood.
3. Misunderstandings about office chair maintenance

4. Safety misunderstandings about office chairs
In the process of using office chairs, some people do not pay attention to the safety issues of office chairs. For example, they will not pay attention to whether the office chair has a qualified air pressure rod, whether the explosion-proof steel plate will be installed, whether the swivel chair and office chair will be regularly inspected and maintained, etc. These problems are very dangerous and may cause injury to the user or even an explosion.
It is very important to adjust office chairs to accommodate people of different heights. Correct desk and chair heights can improve work efficiency, reduce physical fatigue, and even help prevent occupational diseases. Below are detailed instructions.
1. Adjust the height of the office chair
First, adjust the height of the office chair to ensure that when your feet are flat on the ground, your thighs and calves are basically vertical. This is because when the angle between the thigh and calf is too large, it may cause poor blood circulation in the legs, causing numbness or pain in the legs. The correct height should be such that when you sit on a chair, your knees are bent at 90 degrees and your heels are firmly on the ground.
The main methods of adjusting the height of an office chair are as follows:
Method 1: Adjust the height by pulling the handle under the seat of the chair. This handle is usually part of the air lever, and pulling the handle adjusts the pressure within the air lever, thereby changing the height of the chair.
Method 2: If there are two handles under the chair, one is used to adjust the height and the other is used to adjust the angle of the chair back. If you're not sure which is the height adjustment handle, you can try it to find out.
Method 3: For some old-fashioned office chairs, there may be a fixed screw under the backrest. You need to use a tool to loosen and adjust it to the appropriate height, and then tighten it to fix it.
2. Adjust the tilt angle of the office chair
In addition to the height, the tilt angle of the office chair is also very important. Generally speaking, when someone sits on a chair and lifts the operating rod upward, the rebound of the high air pressure in the air rod is resisted, and the chair seat lowers accordingly. This ensures that when the arm hangs down naturally, the upper arm and forearm are basically vertical, and the height of the tabletop should be just in contact with the lower plane of the forearm.
3. Precautions
When adjusting the height of the office chair, you also need to pay attention to the following points:
Adjust according to height: The height of the desk and chair should be adjusted according to the height of the individual. Generally speaking, when we sit on the office chair, the person's eyes should be flush with the computer, so that the computer will not be too large when looking at it. tired.
Moderate height: The height adjustment should also be moderate, not too low, so that people will sink into the office chair. But it shouldn’t be too high, otherwise it will be very hard on the eyes.
Maintain a good sitting posture: Make sure your sitting posture is upright, your buttocks are fully seated on the seat, your waist and back touch the lower part of the chair back, your upper body remains upright, your shoulders droop naturally, your wrists remain in a horizontal position when operating the mouse, and your knees are bent at 90 degrees and your feet are on the ground.
Consider spinal health: Choosing an office chair with good lumbar support and adjustment can help reduce stress on your spine.
To sum up, adjusting an office chair to accommodate people of different heights requires considering several factors, including height, tilt angle, and personal height and sitting habits. Through proper adjustment and attention to these matters, you can ensure that the height of your desk and chair is suitable for individual differences, thereby improving work efficiency and physical health.
How to test whether the height of tables and chairs is appropriate
The appropriate height of desks and chairs is crucial to maintaining good sitting posture, preventing cervical and spinal diseases, and improving work efficiency. Here are a few ways to test whether the height of your desk or chair is appropriate:
1. Natural sitting posture test
Basic principles: The height of the desk and chair should be such that when the user maintains a natural sitting posture, the elbows, knees and the ground remain vertical, the thighs and calves remain as vertical as possible, and the upper body and waist naturally lean against the back of the chair.
Specific operations: First, the user should sit on a chair with feet flat on the ground. Then, check that the tabletop supports your elbows appropriately. If your elbows can rest easily on the table and maintain a 90-degree angle to the table, then the table is roughly the right height. In addition, you should also check whether the height of the chair is such that the thighs are parallel to the ground and the angle between the upper and lower legs is approximately 90 degrees.
2. Use of adjustable tables and chairs
Basic principle: use height-adjustable tables and chairs, and adjust the tables and chairs to the most appropriate position according to the user's height.
Specific operation: Choose a desk and chair with an adjustment function, and adjust the height of the desk and chair according to the user's height and habits to meet the above-mentioned natural sitting posture test standards.
3. Special considerations for female users
Basic principle: Women's bodies are usually relatively petite and should choose tables and chairs that are more suitable for their height.
Specific operations: For female users, the height of the table usually cannot be adjusted, so relatively short chairs and tables should be selected to ensure that the user can sit flat on the chair and maintain correct sitting and writing postures.
4. Prevent cervical and spinal diseases
Basic principle: Appropriate table and chair heights can help users change bad sitting postures and reduce the frequency of cervical spondylosis.
Specific operations: Inappropriate heights of desks and chairs may cause users to adopt twisted postures, causing damage to the cervical vertebrae and spine. Therefore, when purchasing tables and chairs, users should pay attention to choosing tables and chairs with an appropriate height to prevent the occurrence of related diseases.
5. Consider space planning and user height
Basic principle: The height of tables and chairs should be determined according to the height of the user and the actual space used.
Specific operation: When purchasing tables and chairs, in addition to considering your own height, you should also consider space planning and body size differences among family members. For example, if there are taller people in the family, tables and chairs should be selected based on them. Additionally, the effects of wearing different footwear (such as slippers or high heels) should be considered and simulated in a real-life environment.
Through the above test methods, users can effectively evaluate whether the height of their desks and chairs is suitable, and take appropriate measures to adjust if it is not suitable.
To prevent cervical spondylosis, you need to pay attention to the following points of sitting posture:
1. Correct sitting posture
Correct sitting posture is the basic requirement for preventing cervical spondylosis. Improper sitting posture can cause neck and shoulder muscle tension, which can lead to cervical spondylosis. The correct sitting posture should be with the body slightly tilted back and a support on the neck to ensure that the neck releases its own pressure on the support to avoid neck fatigue.
2. Adjust the height of tables and chairs
Improper height of desks and chairs can also increase the burden on the cervical spine. You should try to shorten the distance to the work table and adjust the height of the table and chairs to the most suitable state in proportion to your height. This can reduce the occurrence of cervical spondylosis.
3. Relax your shoulder muscles
Let your arms hang naturally and relax your shoulder muscles, which can reduce fatigue caused by the arms exerting force to maintain their position. In addition, place the leg health pedal so that the knees are slightly higher than the thighs to ensure smooth blood circulation in the legs and also help prevent cervical spondylosis.
4. Maintain a suitable viewing angle
The angle between the line of sight and the vertical line to the center of the earth should be about 115 degrees, that is, the computer screen is slightly lower than the parallel line of sight. This can reduce the burden on the cervical spine and prevent cervical spondylosis.
5. Take regular breaks and activities
After working for about one to two hours, you should purposely rotate your head and neck several times forward, backward, left, and right. This can not only eliminate visual fatigue, but also benefit the health of the cervical spine.
6. Keep your neck warm
Pay attention to keeping your neck and shoulders warm, avoid bearing heavy objects on your head and neck, and avoid excessive fatigue. The time spent working at the desk for a long time under low temperature or cold and humid conditions should be minimized to prevent the occurrence of symptoms of cervical spondylosis.
7. Avoid using air conditioners or electric fans for long periods of time
Blowing air conditioners or electric fans for a long time may aggravate the symptoms of cervical spondylosis. Therefore, you should change your head position regularly while working to avoid working at your desk for long periods of time.
8. Correct bad sitting habits
Bad sitting habits should be regularly checked and corrected, such as avoiding random sitting, multitasking, curled-up and head-supporting sitting postures. These bad habits may increase the burden on the cervical spine and induce cervical spondylosis.
To sum up, correct sitting posture, suitable table and chair height, relaxed shoulder muscles, suitable sight angle, regular rest and activities, keeping the neck warm and avoiding long-term use of air conditioners or electric fans are all ways to prevent cervical spondylosis. important measures for disease. At the same time, it is also necessary to regularly check and correct bad sitting habits to maintain good cervical spine health.
