Guangdong Office Chair Installation

For office chair installation in Guangdong, you can refer to the following general steps, using a five-star-base office chair as an example:

1. Install the Wheels and Five-Star Base
   Align the wheels with the slots on the five-star base, press them in firmly, and ensure the clips are fully secured. Some wheels may need to be rotated to lock them in place; check for stability to prevent them from coming loose during subsequent use.

2. Install the Gas Lift
   Insert the gas lift into the central hole of the five-star base, ensuring vertical alignment. The gas lift is the core component for adjusting the seat height; choose a specification that matches the chair model to avoid installation failure or safety hazards due to size mismatches.

3. Secure the Base Plate and Seat
   Connect the base plate (usually made of metal or plastic) to the seat using screws and tighten them with a screwdriver. Ensure the screws are fully embedded to prevent loosening. Some seats have pre-embedded nuts at the bottom; align them with the holes on the base plate before insertion.

4. Connect the Seat to the Gas Lift
   Align the central hole at the bottom of the seat with the top of the gas lift and press down vertically until it clicks into the fixed position on the base plate. Ensure the gas lift and seat are fully flush to prevent tilting and seat wobbling.

5. Install the Armrests
   Align the armrests with the reserved holes on both sides of the seat and secure them with screws. Adjust the height and angle of the armrests to ensure they are parallel and symmetrical with the seat. Some armrests support multi-directional adjustment; tighten the screws according to your needs.

6. Secure the Backrest
   Align the bottom of the backrest with the bracket at the rear of the seat, secure it with screws initially, and then lock it with the seat cushion bracket. Check the tilt angle of the backrest during installation to ensure it conforms to ergonomic design and avoids excessive forward or backward tilting.

7. Install the Headrest (if applicable)
   Insert the headrest into the reserved hole at the top of the backrest and tighten the fixing screws. The headrest height should be adjustable; test the sliding or rotating function after installation to ensure it works properly.

Precautions:

• Before installation, check the parts list to ensure all small components such as screws and washers are complete.
• Installation methods may vary for different models (e.g., conventional plastic-shell auditorium chairs); refer to the specific instruction manual.
• It is recommended to wear gloves during installation to avoid scratches or finger pinches.
• After completion, check that all screws are tightened and test the seat's functions such as height adjustment, rotation, and tilting to ensure they work properly.
