Ergonomic Chair

More and more people are now working in the office, and a part of heavy manual labor has been declining continuously. The consequence of this process would seem to be improving the physical condition of people. However, various studies show that the office staff suffer  a number of occupational diseases, and the main one is a back pain.

A wrong sitting pose – one of the most frequent cause of pain in a back and waists. Office worker spends at his desk more than 80000 hours of his life. However, many people sit with hunched backs. While this posture is easy to maintain for a very long time because of the minimal muscle tension, it is most damaging for the body. The load, which do not taken by muscles, is immediately transmitted to the spine.

As a result, the stress caused by the sitting too long in the wrong position, creating pressure on the intervertebral discs and constrained supply the muscles with blood. In addition, it can break down the entire metabolism in general, causing circulatory and gastrointestinal disorders, insufficient blood supply to the legs.

In light of all these facts it becomes apparent that one of the main topics related to health in the workplace is the consideration of a sedentary activity as vigorous activity, and the desk chair as its tool.

The ability for a long time to keep the correct posture without any support is primarily a matter of general health. Thus, a help a person maintain a direct position of the back (even if it is against his habits) is the main task of the ergonomic chairs.

In a seated position with straight back the spine takes the form of the letter S, ensuring the correct posture. The pelvis is tilted slightly forward, supporting the lower part of the spine. Thus, a part of spine at the transition from the sacrum to the lumbar spine is supported by an optimal distribution of weight. Due to the inclined position of the pelvis the thorax is automatically lifted, making it easier to breath. So the spine is slightly stretched, the load on the intervertebral disks is distributed evenly. Support of the pelvis and lumbar spine allows even poorly trained muscles to maintain correct position of the back.
