Office chairs are generally used in more formal occasions. In this case, we should respect the basic etiquette, so the person sitting should have a correct posture, and the depth of the chair should not be too deep, because sitting too deep is easy to relax. In this case, it is impossible to maintain a correct sitting posture for a long time, so the depth of the chair to meet the office needs should be shallow.
2, the height of the office chair legs
People who use office chairs must be tall and low. If an office chair with uniform chair legs is adopted, it will easily cause discomfort and discomfort to users and will never reduce work efficiency. Therefore, the legs of office chairs are generally designed to be adjustable in height, which can basically meet the needs of users of all heights.
3, the height of the office chair armrest
Generally, when sitting, many people will get used to hanging their hands or putting them on the handrails. If they are used to hanging their hands, they might as well choose those office chairs with low handrails or even no handrails. If you like the habit of putting your hands on the armrest or shrinking in the middle of the office chair, it is better to choose a chair with a higher armrest.
4, the height of the office chair backrest
If you are required to sit in a dangerous office environment, you can be equipped with a chair without armrest and backrest, or choose one with lower armrest and backrest. If it is a leisure occasion, you can choose an office chair with a high backrest. You can put your weight on your back and lean on the backrest. The height of the backrest can be close to your neck or in the middle of your head.

4. Chassis, the chassis is the part that lifts the chair seat, and the lower part of the chassis is connected with the air drying rod.
5, chair seat, chair seat is generally composed of three parts: board, sponge and cloth. The quality of the board is generally not felt by consumers because it is inside. Sponges generally include regenerated cotton and new cotton. 99% of the manufacturers use it together. The thicker and harder, the higher the cost. Generally speaking, there are three kinds of fabrics: Ma Rong, mesh and leather. The plastic frame is best matched with mesh cloth, which will be more breathable.
6. The thickness of handrails directly affects the quality of office chairs.
7. The back of the chair, the seat of the chair and the back of the chair are separated, and the middle is connected by steel pipes or steel plates. If the thickness of the steel plate is generally 6mm or 8mm. However, it should be noted that if the width of the steel plate is less than 150px, the thickness of the steel plate must be 8mm thick.

9. The function of headrest and waist pillow is to reflect the comfort of the chair. So we have to sit on it and give it a try!
Third, what should sedentary people do to be comfortable?
If there is no condition to change seats, changing the sitting posture can also protect the spine. American sitting expert Joan? Kucher said that the current chair is too deep and soft, so that the legs can't touch the floor normally, and the back will bend? c？ Type of spinal injury.
In fact, office workers can try? Right angle? Sitting posture: after sitting down, legs and thighs should be at right angles as far as possible, shoulders should droop naturally, elbows should be relaxed, upper arms and forearms should be at right angles as far as possible, and eyes should be parallel to the computer screen.
This sitting posture can prevent mouse hands and prevent excessive fatigue of the spine. We can also try to sit on the edge of the chair, don't let the back relax completely and curl up; If the chair surface is too soft and the hips can't be supported, you can pad something a few centimeters away from the front, such as pillows, sweaters, etc., so that the pelvis can lean forward and the ischium can rely on it to prevent the back from bending, improve the position of the hips and make the legs more comfortable.
When driving, you can also support your back with cushions to prevent back pain caused by spinal fatigue. One action relieves spinal discomfort. Experts suggest that every time you sit at 40, get up and exercise, and do appropriate actions such as twisting your neck and stretching your waist.
Kangxiu Takeuchi, president of Takeuchi Hospital in Japan and a plastic surgeon, also suggested a stretching method to relieve sedentary low back pain: put your hands on your back, push your waist forward, and then push it back with your waist several times. In addition, swimming is also a very good way to prevent spinal diseases.
Changing seats and exercising only help to delay and reduce the injury to the spine caused by sedentary. If you have serious neck, shoulder and back pain, numbness of limbs, dyskinesia and other long-term situations that cannot be alleviated, you should seek medical advice in time.
