Standard size of writing desk

Standard size of writing desk
The writing desk is too high and the chair is too low, it will make people form a prone posture, shorten the visual distance, and over time will easily cause the spine to bend and deform and the eyes are myopia. For this reason, the furniture used in daily life must meet the standard; for the height of tables and chairs, the country has standard regulations. Among them, the table furniture height dimension standard can have four specifications of 700mm, 720mm, 740mm, 760mm.
The seat height of chair and stool furniture can have three specifications of 400mm, 420mm, and 440mm. In addition, it also stipulates that the standard size of the table and chair should be used, and the height difference of the table and chair should be controlled within the range of 280 to 320mm; the correct height of the table and chair should be able to maintain two basic verticals when sitting: one is when the feet are flat On the ground, the thigh and calf can be basically perpendicular. At this time, the front edge of the seat surface cannot form pressure on the lower thigh. The second is that when the arms hang down naturally, the upper arm is basically perpendicular to the forearm, and the height of the tabletop should be just in contact with the lower plane of the forearm. This will enable people to maintain correct sitting and writing postures
If the height of the table and chair is unreasonably matched, it will directly affect the person’s sitting posture, which is not conducive to the health of the user. For this reason, the national standard also stipulates that the height of the space under the desk top should not be less than 580mm, and the width of the space should not be less than 520mm. This is to ensure that there is enough space for the legs when people use it.
