The Humanized Computer Chair Should Be Ergonomically
The humanized computer chair should be ergonomically as follows:
First, the angle and surface of the back of the chair should be adjustable and have good support for the neck, back and waist. The comfort of the back, neck and waist determine the fatigue of your thoracic, cervical and lumbar vertebrae, respectively. Therefore, the scientifically designed work chair should have a seat back with adjustable angle and curvature, as well as a well-designed headrest and lumbar pad. The normal human body has three physiological curvatures. Because of physiological requirements, they do not grow in a straight line. The thoracic vertebrae are convex, and the cervical and lumbar vertebrae are convex forward. From the side, the spine is like the connection of two S. Due to this physiological feature, the waist and back cannot be placed on the same plane. Therefore, if you want to achieve a comfortable sitting posture, the design of the back should conform to the natural spine curve. It can maintain the lordosis of the cervical and lumbar vertebrae and the kyphosis of the thoracic vertebrae. Therefore, a well-designed work chair should have the following three support points for the back of the human body:
>> There is an adjustable neck pillow at the head and neck to support the front convex cervical vertebra. >> There is an adjustable surface on the upper back to support the kyphosis thoracic vertebrae.
>> Adjustable lumbar pad at the back of the waist to support the anterior lumbar vertebrae.
Therefore, it is important to buy a reasonable and user-friendly computer chair.
