Direct Sales Office Chair Installation

The installation of direct-sales office chairs should be carried out in accordance with standardized steps. The specific process and precautions are as follows:

I. Installation Steps

1. Assembling Chair Wheels and Five-Star Base
   Insert each chair wheel into the five mounting holes of the five-star base, ensuring that each wheel is fully embedded and free from looseness. After flipping the five-star base, place the thicker end of the gas lift rod vertically against the center hole of the five-star base, ensuring a secure connection between the gas lift rod and the five-star base.

2. Connecting the Gas Lift Rod to the Seat Cushion
   Place the base plate on the bottom of the seat cushion, paying attention to the orientation of the base plate (usually aligned with markings or grooves). Align the screw holes and screw in the screws one by one. For some base plates, it is necessary to screw them in 3-4 turns first and then tighten them one by one to avoid misalignment of the screws. Subsequently, align the seat cushion with the top of the gas lift rod, insert it into the hole in the base plate, and press gently until it is fully seated.

3. Installing the Backrest
   Align the bottom sides of the backrest with the mounting holes on the armrests of the seat cushion. Insert vertically and first secure the bottom of the backrest with screws from the bottom of the armrest brackets. Then align the back of the backrest with the mounting holes on the seat cushion brackets and fix them with a wrench by locking the screws in pairs to ensure that the backrest is free from wobbling.

4. Installing the Armrests
   Press the button below the armrest surface and insert the left and right armrests into the holes of the armrest brackets respectively, ensuring that the catches are fully embedded. Secure with screws (usually 3 screws per side). When tightening, operate symmetrically to avoid tilting of the armrests.

5. Installing the Headrest (if applicable)
   Place the headrest in the middle position at the top of the backrest, press the mounting area to make it fit against the backrest, and complete the fixation by inserting screws through the fixing catches. Some headrests need to be adjusted in height through a slide rail, and the smoothness of the sliding should be tested after installation.

II. Precautions

• Component Inspection: Before installation, check that all components (such as screws, wrenches, gas lift rods, etc.) are complete to avoid work stoppages due to missing parts during the process.
• Reference to Instructions: Follow the instructions or video guidance provided by the brand as a priority. Different models of chairs may have structural differences.
• Cost Confirmation: If you choose the brand's direct-sales installation service, clarify the cost range in advance, including hidden costs such as elevator-free handling (usually 50-100 yuan per floor) and old chair removal (about 120 yuan per time) to avoid subsequent disputes.
• Safe Operation: Avoid excessive force when screwing during the installation process to prevent screw slippage; the gas lift rod should be placed vertically to prevent tilting, which may cause air leakage or damage.

III. Handling Special Situations
If the chair wobbles after installation, check whether the screws are tightened and whether the gas lift rod is aligned with the five-star base; if the headrest cannot be fixed, check whether the catches are fully embedded or whether the screws are loose. If the problem cannot be solved, it is recommended to contact the brand's after-sales service for handling.
