People often use tables and chairs in their daily lives. Tables are used to put things used in daily life, and chairs are where people sit. Although we often use tables and chairs in our daily lives, have you noticed the difference in height between tables and chairs when using them? The height difference between the table and the chair is not a random difference, but a scientific conclusion accumulated through thousands of years of craftsmen's experience. Here, Xiaobian will reveal the secret of the height difference between the table and the chair.
1. international standards for the reasonable height of tables and chairs
there are national standards for the height of tables and chairs. Among them, the height size standard of table furniture can have four specifications: 711mm, 721mm, 741mm and 761mm; The seat height of chair and stool furniture can have three specifications: 411mm, 421mm and 441 mm. In addition, the standard size of tables and chairs is specified, and the height difference between tables and chairs should be controlled within the range of 281 to 321mm.
2. Reasonable height of desk and chair
Because the chair is used in conjunction with the desk, the height of the desk is also very important. It has been proved by research that it is the most suitable that the desk is 29 cm higher than the chair seat. This is because 29 cm of the chair seat is where people sit on their elbows, which is exactly one-third of the height of the human body.
if the height of tables and chairs is not reasonable, it will directly affect people's sitting posture, which is not conducive to the health of users. To this end, the national standard also stipulates that the height of the space under the writing desk is not less than 581mm, and the width of the space is not less than 521 mm. This is to ensure that people can have enough room for their legs when using.
3. Reasonable size of desk and chair
After sitting down, people should put their legs under the desk, so the gap between the drawer and the chair seat should not be less than 1.6 cm. The width between neutral spaces shall not be less than 55cm. It should be pointed out that these sizes are designed for people with an average height of 1.7 meters. If the figure is too high or too low, they can be designed according to the specific height. The width of the seat should also be able to ensure that the hips are supported, and there should be a certain amount of ample space, so that people can adjust their sitting posture at any time to reduce fatigue.
4. Reasonable height of computer desk and chair
The height of computer desk is very important. When we sit at the desk, we naturally put our hands on the desktop, and the elbows are just bent at 91℃, which is the right height for your computer. Keyboard desktop is generally under the desktop, which can be pulled out to save space, but enough space should be reserved in front of the keyboard to support the wrist, which will make the operator comfortable and smooth when operating. The line of sight height should be like this. Close your eyes, and then slowly open them. The line of sight should fall on the core of the computer monitor. If the position of the monitor is too low or too high, it needs to be adjusted to protect the neck muscles.
