Wooden Office Chair Specifications

There is no unified standard for wooden office chair specifications, but they generally adhere to the following dimensional parameter ranges and classification dimensions:

I. Standard Dimensional Parameter Ranges

1. Seat Height: The conventional range is 410-430mm, suitable for most people; specific needs or individuals with height differences may use 390-410mm. The design should ensure that the user's feet are flat on the ground, with knees bent at a 90-degree angle, avoiding leg suspension or excessive pressure.
2. Backrest Height: Typically 410-420mm, with some designs at 390-400mm, it should support the user's upper back to the scapular region, alleviating fatigue from prolonged sitting.
3. Seat Depth: The mainstream range is 400-420mm, with some designs at 380-400mm. It should balance hip support with back fit; excessive depth can lead to lumbar suspension, while insufficient depth can cause strong hip pressure.
4. Backrest Width: Generally 400-420mm, with some designs reaching 400-424mm, it should cover the entire back width to avoid insufficient lateral support.
5. Front Seat Width: 400-420mm, suitable for the average hip width, providing stable support.
6. Backrest Tilt: 98°-102°, ergonomic, helping to maintain a natural upright back position and reduce spinal pressure.
7. Rear Seat Width: 300-400mm (some designs at 380-400mm), it should ensure full contact between the hips and the seat surface, dispersing pressure.

II. Functional Structure Classifications

1. Fixed Four-Legged Chair: Simple structure with fixed four legs, suitable for basic office scenarios, and cost-effective.
2. Adjustable Swivel Chair: Equipped with a pneumatic rod or mechanical lifting device, it can adjust the seat height; some support 360-degree rotation, adapting to multitasking needs.
3. Multi-Functional Customized Chair: Integrates adjustable headrests, lumbar supports, armrests, and other modules, supporting personalized size customization to meet special body types or health needs.

III. Material and Craftsmanship Classifications

1. Solid Wood Frame + Soft-Padded Seat: The frame is made of solid wood (such as oak or walnut), and the seat is made of sponge or memory foam wrapped in fabric/leather, balancing durability and comfort.
2. Pure Solid Wood Hardboard Chair: All-solid wood structure with a hardboard seat, suitable for minimalist styles or short-term use scenarios.
3. Plywood/Veneer + Wood Frame: The frame is solid wood, and the seat or backrest uses plywood or wood veneer, reducing costs while maintaining a wooden appearance.

IV. Dimensional Specification Model Expansion

Some products are subdivided into models based on parameters such as seat height (400-460mm) and seat depth (400-500mm), and should be selected according to the user's height, body type, and usage scenario. For example, tall individuals are advised to choose models with a seat height of ≥430mm and a seat depth of ≥450mm to ensure adequate leg and back support.
