Since the 1980s, the demand for computer work has increased, and office methods have also become diversified. Today, with such rapid technological development, office chairs have evolved from simple sitting devices to ergonomic office appliances.
Today's ordinary white-collar workers spend almost 80% of their time sitting in a sedentary state. Physical stress and tension seriously affect work efficiency and physical and mental health. It is particularly important to use an ergonomic office chair. A truly ergonomic office chair must provide unlimited free movement while supporting the human body.
With the current changes in the way employees work, many employees' work is not limited to doing independent work on the same chair with the same computer. Instead, you need to switch frequently between personal office, focused office, and cooperation with others. They are no longer confined to small cubicles, but often appear in open office spaces or team-configured office spaces, often turning their bodies to communicate with other people, or viewing information on whiteboards, monitors or walls.
A good sitting posture requires the balance of body muscles, bones and spine functions. At the same time, there are corresponding requirements for the use of tables, chairs and related facilities. In many developed countries, office desks and chairs are required to conform to ergonomics to reduce the body's gravity load in the sitting position.
Poor sitting posture or using non-ergonomic desks and chairs can cause a series of problems with human muscles and bones, including sagging shoulder girdle, C-shaped spine curvature, and vertical high-back chairs leading to lumbar kyphosis. These abnormal postures put a lot of pressure on the muscles, bones, joints and spine, and are the main reasons for the high incidence of cervical spondylosis and lumbar disc herniation in office white-collar workers.
It's not a good sitting posture that you feel comfortable with. The correct sitting posture should be that the upper body is straight, the abdomen is retracted, the lower jaw is slightly retracted, and the lower limbs are brought together. If possible, the knee joint should be slightly higher than the hip.
If you are sitting on a chair with a backrest, you should try to put your back close to the back of the chair based on the above posture, so that the lumbosacral muscles will not be fatigued. After sitting for a long time, you should exercise to relax the muscles of the lower limbs.
In addition, patients with lumbar disc herniation should not sit on low stools less than 20cm, and try to sit on chairs with backrests, so that they can bear part of the body's weight and reduce the chance of back strain.
Whenever there is a significant change in work, office tools or team, the basic principles of ergonomics application must be rethinked. Different types of work modes require corresponding solutions, and the dynamic support concept of the seat also needs to be continuously developed to keep up with the ever-changing work processes and office appliances.
