What is the scientific collocation height of tables and chairs?

The scientific collocation height of tables and chairs varies with individual height. Generally, the height of the desk is about 73-76cm, and the height of the chair should ensure that your elbow bends 90, that is, it should be level with the desktop when you knock on the keyboard. Generally speaking, the height of the chair base from the ground should be 40~45cm (especially high or short people are another matter).

Generally, the height of the table is about 73-76cm, which cannot meet the needs of all heights. At this time, you have to look at the chair. The height of the chair should ensure that your elbow bends 90 degrees, that is, it is level with the desktop when you knock on the keyboard; If the seat is too high and the feet can't reach the ground, it will also lead to various problems. You can put some other things under the frame for stepping on.

The height of the chair should be adjustable. You can adjust the height of the chair according to your height. Your thighs are parallel to the ground, your knees are bent about 90, and your feet can step on the ground smoothly. At the same time, when you operate the computer, your head and neck are on the same vertical line. This height of the chair can increase the stability of your body and reduce the degree of spinal involvement.

Extended data

In order to sit comfortably, the design of the chair back should conform to the natural spine curve. It can maintain the lordosis of cervical and lumbar vertebrae and the kyphosis of thoracic vertebrae.

Therefore, a reasonably designed working chair should have the following three supporting points on the back of the human body:

(1) There is an adjustable neck pillow on the head and neck to support the lordosis cervical vertebra.

(2) The upper back has an adjustable curved surface to support the kyphosis thoracic vertebra.

(3) The back waist has an adjustable lumbar pad to support the lordosis lumbar spine.

The comprehensive support of the above three parts can ensure that users can sit up straight when sitting on the computer chair, and maintain the natural curve of the spine, thus avoiding the occurrence of spinal deformation.
