How to Assemble Office Chair Video Step by Step

Refer to the 'Luban Home Service: Office Chair Assembly Video Guide' released in 2025 or follow the step-by-step instructions with illustrations below to complete the assembly:

I. Preparation

1. Tool Preparation: You will need a Phillips screwdriver, an adjustable wrench (or an Allen wrench, depending on the model), a rubber mallet, and scissors.
2. Component Verification: Check that all parts are present, including the chair base, gas lift, seat, backrest, armrests, headrest, screw pack, and instruction manual. Ensure the gas lift is placed upright to prevent air leakage from tilting.

II. Core Assembly Steps

1. Connecting the Chair Base and Gas Lift Place the chair base flat on the ground and insert the gas lift vertically into the center hole of the base. Press down firmly until it is fully seated. If the gas lift does not insert easily, use a rubber mallet to tap gently for assistance, but avoid excessive force that could damage the components.

2. Securing the Seat Align the mounting holes on the bottom of the seat with the top of the gas lift and press down vertically until you hear a 'click' sound, confirming it is locked. For models with tilt functionality, insert the tilt control handle (usually located on the right side) into the corresponding hole and tighten the screw.

3. Installing the Backrest and Armrests

   • Pre-installed Backrest: If the backrest is already connected to the seat, simply adjust it to an upright position.
   • Separate Backrest: Align the backrest with the metal brackets on the back of the seat and secure it with screws. Tighten the screws symmetrically to ensure even pressure distribution.
   • Armrest Installation: Align the armrests with the holes on both sides of the seat, insert screws from the bottom up, and tighten them. It is recommended to tighten the screws alternately to ensure balance.

4. Installing Additional Components

   • Headrest: Insert the headrest rod into the top hole of the backrest and adjust the height as needed.
   • Lumbar Support: Attach it to the corresponding position on the backrest using Velcro or snaps.
   • Wheels: Press the casters firmly into the wheel holes on the chair base. Ensure you hear a 'click' sound to confirm they are securely seated.

III. Post-Assembly Inspection

1. Stability Test: Shake the chair to check for any looseness or unusual noises.
2. Function Test: Test whether the height adjustment, tilt, and rotation functions work properly.
3. Safety Check: Confirm that all screws are tightened, there are no exposed sharp edges, and the wheels are securely installed.
4. Personalized Adjustment: Adjust the tilt tension, headrest height, and armrest width according to your needs.
