There’s a slight difference between a computer desk and a desk.
For modern people, time in using the computer on a desk is much longer than reading. So choosing a “computer desk” is quite important.
In terms of health and utility, a good computer desk should take into account the following factors:
Height > stability > area > other (such as: color, material, special shape)
Take a look at the average person’s posture when they are using a computer desk:
In these three pictures, figure 1 shows a low desktop for adults and a high desktop for children; Figure 2 shows a normal desktop height, and Figure 3 shows a high desktop height.
High desktop will force shoulder lift, causing shoulder pressure, long strain, getting a frozen shoulder, and so on.
Low table is easy to hump, from the thoracic vertebrae, easily getting back pain. Also, the short visual distance will easily make myopia.
The correct height of the desktop should make people’s arms naturally droop, the upper arm and the forearm are basically vertical, the desktop just with the forearm plane contact. As figure 2 shows.
If you usually use keyboard and mouse, you should follow this height size standard.
How to find the right table and chair for your height?
Just to be clear, even if you’re the same height, you need different chairs and tables.
This position is not usually done, but it can be used as a reference for the height of the chair. As shown above, the lower leg is 90 ° from the thigh, and the height between the lower leg and the floor is the height of the chair.
Find a chair that is level, preferably higher, take a deep breath, sit up straight and with your legs dangling, and measure the distance between the surface and the bottom of your feet, which is appropriate for your height.
Place a cushion under your foot and hold it in this position, with your arms hanging naturally, the upper arm at 90 degrees from the lower arm, measuring the lower edge of the lower arm to the ground, which is the height of the table that suits your height.
Just take those two numbers and go buy a table and a chair.
Previously I said, “in terms of health and utility, a table is considered as follows: height > stability > area > others (such as color, material, special shape).
Stability is for safety, one is not to collapse the desktop, hit themselves, smashed the computer, two is conducive to maintaining spinal stability. If the table and chair shake, will drive spinal column twist, over time the spinal column accumulated small damage too much, quantity change causes qualitative change, want to treat not easy.
Stability depends on two factors: mass (weight) and joint connection. It’s better if the table is heavy. If the top is heavy, the legs should be able to be weighed. Joint connection is mainly between the table and the legs of a solid connection, mortise and tenon or hardware connections can be.
The area refers to the length of the arm, as shown below:
A typical rectangular desktop size is 600 by 1200(mm).
Different materials have different textures, quality, and cleanliness (environmental protection), depending on their economic ability to decide.
Color is mainly considered with the home environment into the tie-in degree, not detailed.
