Office Chair Mesh Base

The office chair mesh base typically consists of core components such as chair legs, gas lift cylinders, and chair casters. The materials used include aluminum alloy, stainless steel, nylon, etc. Some bases support custom mold-making, and there are significant price differences for replacement parts in the maintenance market.

Core Components and Installation Methods

Taking the Deli 4901S Staff Mesh Chair as an example, the installation of its base involves two steps:

1. Caster Installation: Fix the casters (chair wheels) one by one into the pre-set holes on the chair legs, ensuring that the buckles or screws are tightened to prevent detachment during use;
2. Gas Lift Connection: Insert the gas lift cylinder (height adjustment column) vertically into the central hole of the chair legs. It is necessary to confirm that the gas lift cylinder matches the interface of the chair legs to prevent tilting, which could lead to the failure of the height adjustment function.
   This design enables quick assembly through modular components, while the gas lift cylinder provides height adjustment functionality to accommodate users of different heights.

Materials and Customization Options

The material of the office chair base directly affects its load-bearing capacity and durability:

• Aluminum Alloy Base: It has high strength and is lightweight, suitable for high-end office settings. It is commonly found in manager chairs or gaming chairs. Some products support custom die-casting mold-making (such as a five-pointed star shape), but the unit price may be as low as ¥0.1 (this may be the unit price for the minimum order quantity for customization and requires further confirmation);
• Stainless Steel Base: It has strong corrosion resistance and is suitable for humid environments. The price of replacement parts in the maintenance market is approximately ¥75.0, and it is mostly used for the repair of swivel chair bases;
• Nylon Base: It has a relatively low cost, is lightweight but has limited load-bearing capacity. The price range is between ¥203.46 and ¥205.3, and it is commonly found in budget-friendly mesh chairs.
  Users can choose the material according to the usage scenario (such as an office or home) and budget. For customization needs, it is necessary to confirm the mold-making cost and minimum order quantity with the supplier.

Price Reference for Replacement Parts in the Maintenance Market

In the maintenance market, the prices of base replacement parts vary significantly depending on the material and function:

• The basic stainless steel base (including a controller and a turntable) costs approximately ¥75.0 and is suitable for replacing aged or damaged swivel chair bases;
• The nylon five-star foot base (including a bracket) has a relatively high price (¥203.46 - ¥205.3). It usually comes with a complete height adjustment mechanism and is suitable for overall replacement;
• For aluminum alloy custom bases, a separate inquiry is required. The price is greatly affected by the complexity of the shape and the surface treatment process (such as anodizing).
  When making a purchase, it is advisable to check the part model (such as the hole spacing of the chair legs and the specifications of the gas lift cylinder) to avoid rework due to mismatches.
