Office Chair Base Tray

Office chair base trays come in a variety of types, with a wide price range. Common products can range from a few yuan to several hundred yuan, depending on their functionality, material, and design complexity.

Common Types and Price Ranges

1. Basic Functional Trays
   These primarily offer simple height adjustment functionality, with materials often being ordinary steel or engineering plastics, featuring a lightweight structure. For example, a lifting base accessory with a wrench tray costs approximately ¥17.0, suitable for users with limited budgets or low functional requirements. These trays are typically adjusted in height using a manual wrench, offering simple operation but generally average durability, suitable for lightweight office chairs.

2. Swivel and Lifting Integrated Trays
   These add a swivel module to the basic lifting function, supporting 360-degree free rotation. The materials are often thickened steel or high-strength plastics, with a more stable structure. Factory-direct swivel and lifting bases cost approximately ¥18.0, offering high cost-effectiveness, suitable for office scenarios requiring flexible sitting posture adjustments. Some products use gas rod designs for smoother adjustment, but attention should be paid to the impact of gas rod quality on safety.

3. High-End Explosion-Proof Trays
   Designed for executive chairs or heavy users, these use thickened explosion-proof steel plates or aerospace-grade aluminum alloy materials, featuring a heavy structure and strong load-bearing capacity. For example, a thickened explosion-proof chair base can cost up to ¥130.0, with some high-end models even exceeding ¥300. These trays are typically equipped with multi-level locking functions, anti-tipping designs, and pass international safety certifications (such as BIFMA standards), suitable for scenarios with extremely high safety and durability requirements.

Core Factors Affecting Price Differences

• Material: Ordinary steel trays have low costs but are prone to rusting; stainless steel or aluminum alloy trays have strong corrosion resistance and higher prices.
• Functionality: Basic lifting models have the lowest prices, while composite functions such as swiveling, tilting, and locking significantly increase costs.
• Safety Design: Explosion-proof structures, overload protection, and other safety modules require additional material and technological investments, often doubling the price.
• Brand and Channel: Factory-direct products have lower prices, while brand premiums or dealer markups can lead to differences in final prices.

Purchase Recommendations

If the budget is limited and requirements are simple, choose a basic model under ¥20; if swivel functionality is needed, recommend mid-range products priced between ¥30-50; if safety and long-term use are pursued, it is advisable to choose explosion-proof trays priced above ¥100 and prioritize confirming whether the product has passed safety certifications.
