What's the difference between a desk and a box?

The difference between "form" and "case" is as follows:

First, the shapes are different

Generally speaking, the position of the leg determines its name, which has nothing to do with height, size and function. The position of the legs is indented into a grid, and the position of the legs near the four corners is a table.

Second, the spiritual level is different.

The difference is that the level of the case is higher than that of the table. For example, often said surprise, anger, consternation are more advanced emotions; If we say that striking the table and staring at the bench are all low-level emotions. Surprise is surprise, striking the table and staring at the eyes is anger, expressing different emotions. Everything related to the table is low, and everything related to the case is high. China people clearly distinguish a carrier, which is the essence of our culture above others.

Tables and seats

Table height and seat height should be reasonable. The height difference between them is 300~320mm. If the desktop is too high, people will shrug their shoulders and bow their heads, and their elbows will be lower than the desktop and feel uncomfortable. For example, long-term desk work will lead to cervical vertebra (spine) hypertrophy; If the desktop is too low, the human abdomen will be compressed, causing muscle tension and fatigue. A reasonable height should make the human body stand upright, the forward leaning angle should not be greater than 30 degrees, the shoulders should be relaxed, the elbows should be bent nearly 90 degrees, and the sight distance should be kept at 350 ~ 400 mm from the desktop.

The width and depth of the desktop should be within the horizontal movement range that the hand of the sitting person can reach, and necessary appliances can be placed. For example, the width and depth of the square table are generally 750 ~1000 mm; The width of single cabinet table is 900 ~ 1200mm, and the depth is 500 ~ 600mm. Dining table, conference table, etc. , multi-person sharing, 500 ~ 600 mm wide per capita. The activity space under the table is generally not less than 520mm in width, not less than 450mm in depth and not less than 580mm in height, with the principle of keeping the lower limbs of the seated person comfortable.
