Office Chair Tray

The tray (base) of an office chair is a core component that affects stability, durability, and functionality. When purchasing, it is essential to focus on material quality, functional compatibility, and after-sales support.

I. Material and Price Differences

The material of the tray directly impacts cost and performance. Common types include:

1. Die-cast aluminum alloy: High strength and corrosion resistance, suitable for high-end office chairs, priced around ¥40.0 (e.g., products from Foshan Shengdeli Home Furnishings Co., Ltd.).
2. Steel/iron powder-coated: Basic models start as low as ¥6.65, with reinforced explosion-proof versions around ¥19.0. These offer good value but require attention to rust prevention (e.g., products from Foshan Nanhai Chuanyin Hardware Accessories Processing Factory).
3. Special design models: For example, aluminum alloy P-shaped bases (compatible with executive chairs) are priced at ¥58.9, emphasizing load-bearing capacity and ergonomic compatibility.

Recommendation: Choose materials based on budget. Opt for aluminum alloy for high-end chairs and steel for budget-friendly options, ensuring rust-proofing is confirmed.

II. Functional and Design Considerations

The tray must support rotation, height adjustment, and recline functions, with some products optimized for specific scenarios:

1. Dynamic support: For example, the Butterfly Mid-Back Office Chair Base (¥16.0) features ergonomic design with balanced mesh to distribute pressure and reduce fatigue during prolonged sitting.
2. Load-bearing stability: Executive chair trays typically have reinforced frames to accommodate heavier users. Verify maximum load capacity (e.g., 120kg or above).
3. Compatibility: Ensure tray dimensions match the seat and gas lift. Taller users should choose models with a larger recline angle (e.g., 135° or more).

Note: More functions generally mean higher prices. Choose based on actual needs to avoid over-investing in complex designs.

III. Key Purchase Recommendations

1. Material certification: Prioritize products with international certifications like BIFMA or SGS to ensure safety (e.g., high-elastic breathable mesh, explosion-proof gas lifts).
2. After-sales support: Select suppliers offering a 7-day replacement and 1-year warranty (e.g., Foshan Shengdeli Home Furnishings Co., Ltd.) to minimize post-purchase risks.
3. Industry insights: China's office chair industry is concentrated in Anji County, Zhejiang, with 177 million units produced in 2024. The配件 (accessory) market is well-supplied, but distinguish between original and aftermarket parts.
