Admin October 17, 2026

The installation steps for sofa office chairs vary depending on the model. Below are the installation methods for common models:

P512 Sofa Chair

  1. Install the five-star base and gas lift: Insert the five casters into the five-star base one by one, then insert the thick end of the gas lift into the center hole of the five-star base and press gently to ensure stability.
  2. Secure the armrests: Align the armrests with the holes on both sides of the seat cushion, use six medium screws (6*30MM) for initial fixation, and then tighten them one by one with a wrench.
  3. Install the tray: Align the tray with the reserved holes on the seat cushion, secure it with four short screws, and tighten them with a wrench.
  4. Connect the backrest rod and backrest: After inserting the gas lift into the tray, align the backrest rod with the holes on the backrest, secure it with three long screws, tighten the screws, and then tighten the knob.
  5. Secure the headrest: Insert the headrest into the top hole of the backrest and tighten it with a knob.

  1. Assemble the base: Check the completeness of the parts, insert the five casters into the base, install the gas lift, and cover it with a dust cover.
  2. Remove the backrest screws: Use an Allen wrench to unscrew the four pre-installed screws on both sides of the backrest.
  3. Install the footrest: Unscrew the four screws on the base, ensure the arrow points forward, align the footrest with the holes on the base, insert it, and secure it.
  4. Connect the backrest and seat: Align the backrest with the holes on both sides of the seat, place it in, and tighten the screws on both sides.
  5. Install the side covers: Align the side covers with the notches on the backrest, snap them in, and press down firmly until they fit snugly.

  1. Handle the fabric cover: After opening the package, turn the fabric cover to the front (the correct color is the one after turning it over).
  2. Install the frame: Take out the crossbeam, screw pack, and AB legs (short leg in front, long leg in back), install the crossbeam downward, secure the frame at both ends with screws, and tighten them with a small wrench.
  3. Adjust the foot covers: Remove the protective covers from the new packaging and adjust the positions of the foot covers.
  4. Secure the armrests and backrest: Align the protruding part of the seat cushion and backrest with the frame, slide the armrests onto the tubes, adjust slightly if the holes do not align, and press down firmly after installation to secure them.
  5. Complete the installation: Turn over the fabric cover, pull out the backrest pillow from the back, and the chair is now installed.

Precautions:

  • Check the parts list before installation to avoid omissions.
  • Control the force when using tools (such as wrenches and Allen wrenches) to prevent slipping or damaging the parts.
  • Different models have different screw specifications (such as medium screws, short screws, long screws), so follow the instructions strictly.
  • Test the lifting function of the gas lift after installation to ensure it works properly.
