Office Chair Base Catalog

Currently, a complete office chair base catalog is not directly provided, but some physical images and type descriptions can be obtained through merchant channels. The office chair base, as the core component that supports the seat and connects the gas lift and chair legs, directly affects user comfort and safety. Based on available information, the types and characteristics of chair bases can be summarized as follows:

I. Base Types and Physical Displays

Suppliers on some e-commerce platforms (such as Alibaba) display physical images of various office chair bases, covering the following mainstream types:

1. Metal Base: Primarily made of metal materials, with a simple structure, commonly found in basic office chairs, relatively low in price (about 5-15 yuan), suitable for scenarios with low functional requirements.
2. Adjustable Height and Rotating Base: Integrates height adjustment and rotation functions, enabling height adjustment through a gas lift, suitable for users of different heights, with a price range of about 10-30 yuan.
3. Internet Cafe/Computer Chair Base: Designed for long-term use scenarios, emphasizing durability, with some products using thickened steel plates, priced at about 20-50 yuan.
4. Boss Chair/Gaming Chair Multi-functional Base: Supports multi-functional adjustments such as reclining, locking, and sliding rails, mostly made of engineering plastics or alloys, relatively high in price (30-80 yuan), commonly found in high-end seats.
5. Specially Named Bases: Such as the "Butterfly Base" (due to its shape resembling a butterfly spreading its wings) and the "Carefree Base" (emphasizing reclining comfort), are mostly vivid descriptions of the structure or functions by merchants, and their performance needs to be judged based on specific parameters.

II. Materials and Technological Innovations

Some product promotions mention the application of new materials:

• Sixth-Generation Space Base: Uses space fiberglass materials, featuring a 4-bar linkage support effect, dispersing pressure through a multi-bar structure, enhancing stability and comfort during reclining, commonly found in high-end gaming chairs or ergonomic chairs.
• Metal and Plastic Composite Structure: Some bases combine metal frames with high-strength plastics, balancing strength and lightweight, reducing costs while extending service life.

III. Suggestions for Obtaining a Complete Catalog

If detailed technical parameters, structural cross-sections, or installation instructions are required, it is recommended to obtain them through the following channels:

1. Contact Suppliers: Directly request product catalogs or technical documents from e-commerce platform merchants, some of whom can provide PDF versions of catalogs.
2. Brand Official Website Inquiries: Well-known brands (such as Herman Miller and Ergohuman) usually publish product manuals on their official websites, including structural diagrams of chair bases.
3. Industry Exhibition Materials: At furniture exhibitions, chair base suppliers often display samples and distribute brochures, allowing on-site access to graphic materials.

Summary: Currently, public channels mainly display base types and physical images, and complete catalogs need to be obtained through suppliers or brand owners. When purchasing, it is recommended to comprehensively evaluate based on functional requirements (such as whether reclining or sliding rails are needed), material durability, and budget.
