Dimensions of White Office Chairs
The typical dimensions of white office chairs are as follows: seat height ranges from 40cm to 45cm, seat width from 45cm to 50cm, seat depth from 40cm to 45cm, and backrest height from 80cm to 100cm. The specific choice should be based on ergonomics and actual usage scenarios.

Seat height is a crucial parameter affecting sitting comfort, with a typical range of 40cm to 45cm. This height is designed based on ergonomic principles and should match the height of the office desk to ensure that the user's legs hang naturally and feet rest flat on the ground when seated, avoiding leg suspension due to excessive seat height or knee compression due to low seat height. For example, if the office desk height is between 72cm and 76cm, a chair with a seat height of 42cm to 44cm can create a reasonable desk-seat height difference, reducing fatigue from prolonged sitting.
Seat width and depth directly affect sitting stability and activity space. The typical seat width is between 45cm and 50cm, accommodating the user's hip width with appropriate allowance to prevent body leaning due to narrowness or arm placement issues due to excessive width. The typical seat depth is between 40cm and 45cm, ensuring that when the user's back is fully against the backrest, there is a 2cm to 5cm gap between the back of the knee and the front edge of the seat to prevent compression of blood vessels and nerves. For example, the VIHALS white chair has a seat depth of 47cm, close to the upper limit, suitable for larger users or those needing more leg support.
The backrest height should cover the area from the waist to the back, with a typical range of 80cm to 100cm. This design provides complete spinal support, reducing lumbar pressure. Some ergonomic chairs further adapt to different heights and usage scenarios through adjustable backrest heights (e.g., 75cm to 110cm) and angles (e.g., 90ยฐ to 135ยฐ). For example, users taller than 175cm can choose models with a backrest height of over 90cm to ensure neck and head support; when needing to recline for rest, the backrest can be adjusted to 110ยฐ to 135ยฐ to distribute body pressure.
When making a selection, it is necessary to consider the user's height, desk height, and usage habits comprehensively. For example, users between 160cm and 170cm in height can choose chairs with a seat height of 40cm to 42cm, seat width of 45cm, seat depth of 40cm, and backrest height of 80cm to 90cm; while users taller than 180cm should choose models with a seat height of 44cm to 45cm, seat width of 50cm, seat depth of 45cm, and backrest height of 95cm to 100cm to ensure long-term comfort and health.
