Dimensions of Solid Wood Office Chairs in Jiulongpo

The specific dimensions of the solid wood office chairs (classroom chairs) purchased by the Jiulongxin Campus of the Jiulongpo Vocational Education Center in Chongqing have not been directly announced, but reasonable inferences can be made based on industry standards and parameter ranges.

I. Seat Width Range

According to the standard for office furniture and office chairs and industry practices, the seat width of solid wood office chairs is directly related to whether they are equipped with armrests:

• Armless chairs: The seat width is not less than 380mm, suitable for compact spaces or temporary use scenarios.
• Chairs with armrests: The seat width is generally not less than 460mm, with conventional models concentrated in the range of 480-540mm. Models emphasizing comfort (such as executive chairs) can reach 520-560mm. Since the classroom chairs in the procurement project are explicitly equipped with solid wood armrest surfaces, their seat width should fall within the category of chairs with armrests. It is inferred that the actual dimensions may be close to 500-540mm to balance comfort and space occupation.

II. Seat Height and Backrest Height

• Seat height: Typically 410-430mm, with some custom requirements possibly adjusted to 390-410mm. This height range is compatible with most office desks (standard height 720-760mm), ensuring that users' thighs are parallel to the ground when sitting, reducing leg pressure.
• Backrest height: Generally 410-420mm, or designed for specific needs as 390-400mm. The backrest height needs to cover the lumbar to thoracic region of the human body, providing lumbar support and avoiding fatigue from prolonged sitting.

III. Seat Depth and Backrest Tilt

• Seat depth: The common range is 400-420mm, with some models possibly shortened to 380-400mm. The seat depth should ensure that when the user's back is in contact with the backrest, there is approximately a 50mm gap between the back of the knee and the front edge of the chair to avoid compressing blood vessels.
• Backrest tilt: Typically 98°-102°, close to the natural sitting posture of 100°, which can disperse back pressure and enhance comfort.

IV. Other Key Parameters

• Load-bearing capacity: The chassis uses a tilt mechanism and a safety gas spring, with a load-bearing capacity of ≥150kg, meeting the needs of users of different body types.
• Footrest and wheels: An aluminum alloy five-star footrest paired with nylon wheels ensures smooth movement and high durability.

Summary: Although there are no precise dimensional data, based on industry standards and parameter descriptions, it can be inferred that the seat width of this solid wood office chair is approximately 500-540mm, the seat height is 410-430mm, and the backrest height is 410-420mm. Other dimensions conform to the design logic of conventional office chairs. Specific values need to be based on actual product measurements or procurement contracts.
