Dimensions of Bow-Shaped Office Chairs

The common dimension ranges for bow-shaped office chairs are as follows, with each parameter designed based on ergonomics and adaptability to office scenarios:

1. Seat height: 40 - 50 cm, recommended 45 cm for office scenarios
Seat height is a crucial parameter affecting sitting comfort. In a standard adult sitting posture, the knee bend angle should be kept at 90° to distribute leg pressure evenly. Therefore, the seat height is usually designed to be 40 - 50 cm. In an office scenario, when paired with a standard office desk that is 75 cm high, it is recommended to choose a seat height of 45 cm. At this height, when the arms hang naturally, the elbow height is level with the desktop, which can prevent shoulder and neck fatigue during long-term keyboard or mouse operation. If the seat height is too low, one needs to bend forward; if it is too high, the legs will be left hanging, both of which will increase the physical burden.

2. Seat depth: 40 - 45 cm, requiring a balance between support and activity space
Seat depth refers to the distance from the front edge of the seat to the backrest, directly affecting leg comfort. 40 - 45 cm is the mainstream design range: if the seat depth is too shallow (less than 40 cm), the front part of the thighs is likely to be left hanging, causing concentrated pressure on the buttocks; if the seat depth is too deep (more than 45 cm), the back of the knees (the popliteal fossa) will be compressed by the front edge of the seat, impeding blood circulation. In an office scenario, it is recommended to choose according to height: users under 170 cm can choose 40 - 42 cm, and users above 170 cm can choose 43 - 45 cm to ensure that the thighs are fully in contact with the seat and there is no compression on the popliteal fossa.

3. Overall width: 50 - 60 cm, balancing stability and freedom of movement
Overall width refers to the horizontal distance between the outermost sides of the chair, which needs to meet both stability requirements and user activity space. 50 - 60 cm is a common range: if the width is too narrow (less than 50 cm), the chair will be unstable and prone to tipping over; if the width is too wide (more than 60 cm), it will take up too much space and affect passage in the office area. For a standard office scenario, a width of about 55 cm can balance these two requirements, accommodating users of different body types (such as adults with a shoulder width of 45 - 50 cm) without appearing bulky.

4. Seat width: about 50 cm, suitable for most body types
Seat width refers to the horizontal distance between the two sides of the seat, directly affecting the support for the buttocks and thighs. The mainstream design is about 50 cm, which can cover the needs of most body types: for leaner users, 50 cm can provide sufficient wrapping to prevent sliding; for heavier users, a width of 50 cm can distribute the pressure on the buttocks and reduce local compression. If the seat width is too small (less than 45 cm), long-term use can easily lead to buttock fatigue; if it is too large (more than 55 cm), it may restrict the natural placement of the legs.
