Admin October 19, 2026
The installation of different models of office chairs/sofa chairs requires selecting the corresponding method based on the specific model. Below are the installation steps and general precautions for common models:

1. Installation Steps for Sofa Chair xky-145
- Support Leg and Backrest Adjustment: Extend the support legs to a stable position and adjust the backrest to a flat position to ensure structural stability.
- Footrest Adjustment: Adjust the height of the footrest in multiple gears according to your needs, raising or lowering it to a comfortable angle.
- Armrest Frame Fixation: Insert the black plug into the contact point between the armrest frame and the ground, and gently tap it with a tool to make it fit snugly and avoid loosening.
2. Installation Steps for P9 Executive Sofa Chair_176
- Pre-installation of Short Screws: Align the four short screws with the holes on the base and insert them. Do not tighten them yet. After all screws are inserted, tighten them one by one to ensure balance.
- Backrest Fixation: Insert the backrest directly into the base, and install 2 long screws on each side and tighten them completely to enhance structural stability.
- Seat Cushion Tray Installation: Align the seat cushion tray with the gas rod and insert it, adjusting it to a rearward position to match ergonomic design.
3. General Sofa Chair Installation Tutorial
- Component Inspection: Before installation, check that all components (such as casters, gas rods, screws, side covers, etc.) are complete to avoid interruptions during the process.
- Base Assembly:
- Insert the casters into the four corners of the base, ensuring the clips are in place;
- Insert the gas rod and cover it with a dust cover to prevent dust from entering and affecting the lifting function.
- Connection of Chair Back and Seat:
- Use an Allen wrench to unscrew the pre-installed screws on both sides of the chair back;
- Align the arrow direction on the base (usually the arrow points forward), align the holes on the footrest with the holes on the seat, and insert them;
- Align the chair back with the holes on both sides of the seat and tighten the screws (operate symmetrically on both sides).
- Side Cover Installation: Insert the side cover into the notch on the chair back and press it in firmly until it fits completely, covering the screw holes to enhance aesthetics.
General Precautions
- Tool Preparation: Depending on the model, tools such as an Allen wrench and screwdriver may be required. Prepare them in advance.
- Force Control: When tightening screws, avoid excessive force that may cause the screws to slip. The principle is to 'tighten but not deform'.
- Safety Test: After installation, check that all components are secure and test whether the lifting and rotation functions are normal.
- Model Matching: If the model is not listed above, it is recommended to contact the seller to obtain an exclusive installation video or manual to prevent misoperation.
Tip: For sofa chairs with complex structures (such as those with electric functions), it is recommended that two people collaborate on the installation to ensure safety and efficiency.
