Office Chair Upgrade Tray

The office chair upgrade tray should be selected according to the specific model and installed correctly. The prices of trays from different suppliers vary significantly, so it is necessary to choose based on functional requirements and budget.

I. Installation Method
The installation steps for trays vary among different models of office chairs and should be carried out strictly according to the instructions. Taking the P600 computer chair as an example, when installing the new third-generation tray, pay attention to the following:

1. Component Assembly: Place the five-star base upside down, insert the five casters in sequence, and then insert the thick end of the gas cylinder into the five-star base and press lightly to secure it.
2. Tray Fixation: Align the shorter end (rear end) of the tray with the screw holes on the seat cushion, use four 6×20 short screws for initial fixation, and then tighten them one by one with a wrench to ensure a firm connection between the tray and the seat cushion.
3. Gas Cylinder Insertion: Insert the gas cylinder vertically into the circular hole on the tray, adjust the position of the armrest cushion, and then install the lumbar support to complete the overall assembly.

For the installation of the W708 sponge-type computer chair, special attention should be paid to the connection between the armrests and the backrest:

1. Armrest Fixation: First, use four short screws to fix the armrests to the backrest, and then use four long screws to connect the armrests to the seat cushion, ensuring that the screws are tightened to avoid loosening.
2. Headrest Installation: Use two medium-sized screws to fix the headrest to the backrest, and finally insert the gas cylinder and adjust the position of the tray.

II. Price Reference
The prices of trays vary significantly depending on the material, function, and supplier:

1. Basic Trays: For example, the spray-painted iron tray from Anji Dipu Bofeng Furniture Accessories Business Department (6.65 yuan) and the 10X10 thickened tray from Foshan Nanhai Chuanyin Hardware Accessories Processing Factory (4.75 yuan) are suitable for users with a limited budget and low functional requirements.
2. Function-Upgraded Trays: The rotating, adjustable, and lifting middle-class chassis from Foshan Shengdeli Home Furnishings Co., Ltd. (17 yuan) and the adjustable swivel chair tray from Shaoxing Jinhang Home Furnishings Co., Ltd. (9.22 yuan) provide basic lifting functions at moderate prices.
3. High-End Multi-Functional Trays: The heavy-duty export tray from Foshan Shengdeli Home Furnishings Co., Ltd. (52.3 yuan) and the aluminum alloy P-shaped chassis (58.9 yuan) support complex functions such as forward and backward rocking and rotating lifting, suitable for scenarios with high comfort requirements.

III. Purchase Recommendations

1. Function Matching: Choose a compatible tray according to the model of the office chair, and prioritize confirming parameters such as screw hole positions and gas cylinder specifications.
2. Material Consideration: Aluminum alloy trays are more durable than iron ones but are more expensive; spray-painted iron trays require rust prevention treatment.
3. Supplier Reputation: Choose suppliers that offer services such as a 7-day replacement guarantee and 24/48-hour shipping (such as Foshan Nanhai Chuanyin Hardware Accessories Processing Factory and Shaoxing Jinhang Home Furnishings Co., Ltd.) to reduce after-sales risks.
