When choosing the size of the office chair, consider the size of the seat, backrest, armrest and other key parts to ensure that the office chair matches the size and use needs of the human body. The following are some suggestions:
Seat size
Seat width: It is generally recommended that the seat width is between 40-50 cm. For burly people, you can choose a width close to 50 cm to ensure that there is enough space on both sides of the buttocks after sitting down, and you will not feel crowded and can freely move.
Seat depth: The appropriate seat depth should be about 40-45 cm. This depth enables the user to sit down, most of the thigh can be supported by the seat, and there is a certain distance between the back of the knee and the front of the seat, so as to avoid the knee being compressed and ensure the smooth blood circulation of the leg.
Backrest size
Backrest height: The backrest height is usually between 70-120 cm. If you want the office chair to provide better neck support, you can choose a product with a higher backrest and close to 120 cm, which can provide effective support for the neck and reduce neck fatigue when the head is leaning on the backrest. If it is mainly to support the waist, a backrest with a height of about 90 cm can usually meet the needs.
Backrest width: The backrest width is generally between 40-60 cm. A wider backrest can provide more comprehensive support for the body, especially for people with wider shoulders and backs, choosing a backrest close to 60 cm width can make the body better lean on the back of the chair and feel more comfortable.
Handrail size
Armrest height: Armrest height is usually between 20-30 cm, the distance from the seat surface to the top of the armrest. The appropriate height of the handrail should be able to enable the user in a natural sitting position, the arm is easily placed on the handrail, the elbow is naturally bent, about 90° -100 °, which can reduce the burden on the arm and shoulder.
Armrest spacing: armrest spacing is generally between 45-60 cm. The wider armrest spacing allows the user to have more free activity space for the arm when working, especially when using a computer or writing, and will not feel cramped because the armrest spacing is too narrow.
Overall height
The overall height of an office chair (from the ground to the top of the back) is usually between 100-130 cm. But more importantly, the height adjustment range of the seat should generally be between 40-50 cm, to ensure that the user can adjust the seat to the appropriate position according to their height and the height of the table, to ensure that the feet are flat on the ground, and the knee is at the same level with the hip.
