Office Chair Base Tray
Office chair base trays come in a variety of types, with a wide price range, and their installation methods vary depending on the chair type.
I. Common Types and Price Ranges
Office chair base trays can be classified into multiple types based on material and function. Die-cast aluminum alloy trays are known for their high strength and durability, often used in mid-to-high-end office chairs, with prices typically ranging from ยฅ30 to ยฅ58.9; swivel, leisure, and height-adjustable office chair base trays support multi-directional adjustment functions, with a broad price range from ยฅ15 to ยฅ50, depending on the complexity of the adjustment mechanism; basic plastic trays are characterized by their light weight and low cost, with prices mostly between ยฅ4.75 and ยฅ15, suitable for budget-friendly office chairs. Different brands and design details (such as hole layout and load-bearing capacity) further influence prices, so purchases should be made based on budget and needs.
II. Installation Points and Precautions
- Tray Direction Identification: The front end of the tray is usually designed with a longer distance between holes, and the correct direction must be ensured during installation. For example, the tray of the P600 computer chair should have the shorter end as the rear end, aligned with the user's right hand when seated, to avoid incorrect direction leading to adjustment function failure or structural instability.
- Fixing Method and Screw Selection: The connection between the tray and the seat cushion is mostly fixed with screws. Taking the P600 as an example, four short screws (6ร20) are required, tightened through pre-set holes; although the installation steps for the W708 computer chair do not detail the screw specifications, it also emphasizes precise alignment between the tray and the seat cushion, and the screw type and quantity should be confirmed by referring to the specific instruction manual.
- Chair Type Compatibility: The design of trays may vary for different chair types. For example, trays for height-adjustable chairs need to reserve holes for the installation of the pneumatic rod, while fixed trays do not have this structure. Before installation, check the compatibility between the tray model and the chair body to avoid rework due to size mismatch.
III. Impact of Design Differences on Usage
The hole layout of the tray directly affects adjustment flexibility. Some high-end trays adopt a multi-hole design, supporting forward, backward, left, and right adjustments to accommodate users of different body types; while basic trays have fewer holes and limited adjustment range. Additionally, the tray material determines its load-bearing capacity, with aluminum alloy trays capable of bearing over 120kg, and plastic trays recommended to be kept within 80kg, as overweight use may lead to tray deformation or breakage.
Summary: The selection of an office chair base tray should consider material, function, and budget comprehensively. During installation, strictly follow steps such as direction identification and screw fixation, and pay attention to chair type compatibility. Proper use can extend the chair's lifespan and enhance user comfort.
