Office Chair Base Plate
The price of office chair base plates (chassis trays) varies depending on the type, with common types ranging from 6.65 yuan to 58.9 yuan. When repairing, it is important to choose certified parts and follow proper procedures.
Common Types and Price Ranges
Office chair chassis trays vary significantly in price based on material, functionality, and application scenarios. Die-cast aluminum alloy trays are priced higher due to their high material strength and durability, costing approximately ยฅ40.0. Aluminum alloy P-shaped chassis, with their complex design and upgraded material, are the most expensive, reaching ยฅ58.9. Functional chassis, such as swivel and adjustable height chair trays (ยฅ13.0) and office bar chair chassis trays (ยฅ19.0), are slightly more expensive than basic models due to their integrated lifting or swivel functions. Economical chassis, such as iron spray-coated trays (ยฅ9.0), internet cafe/computer/bar office swivel chair chassis (ยฅ6.65), and office chair chassis for executive chairs (ยฅ8.55), are primarily made of low-cost iron or feature simple designs, suitable for budget-constrained scenarios. Additionally, mid-back chassis (ยฅ17.0) and butterfly mid-back swivel chair chassis (ยฅ16.0) are designed for mid-back chairs and are moderately priced.
Maintenance and Replacement Tips
When a chassis tray fails, it can be replaced by removing screws to separate the chassis, gas lift, and chair legs. Ensure the chair is in a stable position before operation to prevent accidental rebound of the gas lift. When repairing, it is recommended to prioritize parts with international certifications such as SGS and TUV, which have undergone safety testing to reduce the risk of breakage or loosening. For example, aluminum alloy chassis should be checked for intact surface oxidation layers, while iron chassis should be confirmed to have no peeling of the spray-coated layer to prevent rusting and affect service life. If wear is present at the connection between the chassis and the gas lift, the matching gas lift should be replaced simultaneously to avoid secondary failures due to compatibility issues.
Purchase Recommendations
Choose a chassis type based on the usage scenario: for frequent swiveling or height adjustment needs, opt for a swivel and adjustable model; for heavy-duty scenarios (such as executive chairs), prioritize aluminum alloy or thickened iron chassis; for budget-constrained and fixed usage, select economical iron spray-coated or internet cafe-specific models. When purchasing, verify the interface dimensions (such as hole spacing and thread specifications) between the chassis and the chair to avoid installation difficulties due to mismatches.
