Office Chair Armrest Installation

Admin October 16, 2026

The steps for installing armrests on office chairs vary depending on the model, as detailed below:

Model 205/206 Office Chairs

  1. Connect Armrests to Backrest: Use four M6*25mm screws to initially secure the armrests to the backrest. Ensure the screws are fully tightened to prevent loosening.
  2. Install Upper and Lower Parts of Armrests: Select two M6*20mm screws and fit them with matching washers to secure the upper and lower connection points of the armrests. The washers help distribute pressure and prevent wear on the material caused by direct contact with the screws.
  3. Install Decorative Covers: After securing the screws, align the decorative covers with the mounting holes and press or rotate them into place to conceal the screws and enhance aesthetics.

Model C100 Office Chairs

  1. Place Armrest Tube Washers: Insert the dedicated washers into the designated positions on the armrest brackets, ensuring they are flat and aligned with the bracket holes. The washers reduce friction and enhance structural stability.
  2. Assemble Backrest and Armrests: Insert the backrest and armrests as a whole into the corresponding slots on the seat cushion, paying attention to the correct orientation to avoid damaging the components by forcing them in.
  3. Secure Backrest to Chassis: Use three M8*20 screws, along with enlarged washers, to tightly connect the backrest to the tail plate of the chassis. Tighten the screws in a diagonal sequence to ensure even pressure distribution.
  4. Connect Armrests to Backrest Linkage: Fix the armrests to the backrest linkage using four M8*78 screws and enlarged washers. Check the horizontal alignment of the armrests during this step to prevent tilting that could affect the user experience.

Additional Notes

  • If the office chair model is not specified in the reference information (e.g., models other than 205/206 and C100), no specific installation steps are available. It is recommended to contact the manufacturer for instructions or video guidance.
  • Before installation, verify the screw specifications and quantities to avoid using incorrect parts that could compromise structural stability.
  • It is advisable to use an electric screwdriver or manual wrench during operation, controlling torque to prevent stripping the screws.
  • After completion, gently shake the armrests to test their stability, ensuring there is no looseness or unusual noise.
