Office Chair Height 40

Admin October 10, 2026

The height of 40 centimeters for an office chair falls at the lower end of the adult chair height range (40 - 50 centimeters) specified in the national standard GB/T 3976 - 2014. It is suitable for people of specific heights and requires a table of an appropriate height to be paired with.

Suitable Height Range

A 40-centimeter office chair height is mainly suitable for adults with a height of approximately 155 to 165 centimeters. In terms of ergonomic suitability, it has a clear correspondence with specific height ranges. For example, for a height of 155 centimeters, a recommended seat height is 39 - 41 centimeters; for a height of 160 centimeters, a recommended seat height is 42 - 43 centimeters. Therefore, a 40-centimeter seat height is an ideal choice for the height range of 155 to 160 centimeters. However, for people close to 165 centimeters in height, this seat height may be slightly low, and the comfort level during use may be somewhat affected. On the other hand, for people around 150 centimeters in height, this seat height may be slightly high, and they may not be able to achieve the best user experience either.

Suitable Table Height

When the seat height of a chair is around 40 centimeters, the choice of table height is crucial. Generally, a table height of around 70 - 75 centimeters is more appropriate. This height combination allows the arms to rest naturally on the table surface, enabling the elbow joints to form an angle of about 90 degrees, which is convenient for operating a computer keyboard and mouse. At the same time, it allows the eyes to look straight at the center of the computer screen, avoiding excessive bowing or raising of the head, and effectively reducing fatigue in the neck and shoulders. In addition, the national standard recommends that the height difference between the table and the chair should be controlled within 28 - 32 centimeters. According to this standard, the table height that matches a 40-centimeter seat height is roughly in the range of 68 centimeters (40 centimeters + 28 centimeters) to 72 centimeters (40 centimeters + 32 centimeters). An appropriate combination of table and chair heights is very important for people who use office equipment for long periods. It can not only improve work efficiency but also protect physical health and prevent various occupational diseases caused by poor sitting postures.
