3. Assembly Instructions

Follow these steps for proper assembly of your COLAMY Ergonomic Mesh Office Chair. It is recommended to have a second person assist with certain steps.

1. Assemble the Base: Turn the star base upside down. Press the casters firmly into each base leg. Then, insert the gas piston into the center hole of the star base.
2. Attach Arms to Seat Cushion: Secure the arms to the underside of the seat cushion using the provided bolts (M6*35mm) and wrench. Ensure they are tightly fastened.
3. Attach Back Cushion to Seat Cushion: Connect the back cushion to the seat cushion using the M8*20mm bolts and wrench. Tighten all bolts securely.
4. Connect Seat to Base: Carefully place the assembled seat part onto the gas piston, pushing down firmly until the connection is secure.
5. Install Headrest: Attach the headrest to the top of the back cushion using the M6*16mm bolts and wrench. Ensure it is stable.

4. Operating and Adjustments

Your COLAMY office chair offers multiple adjustment options to customize your seating experience for optimal comfort and support.

• Seat Height Adjustment: Use the lever located under the seat (often combined with tilt lock) to raise or lower the seat. Pull the lever up while standing to raise, or while seated to lower.
• Tilt Lock and Tension: The same lever used for height control can also lock the chair's tilt. Pull the lever outwards to allow tilting, push inwards to lock the tilt at your desired angle (up to 130°). Adjust the tilt tension by rotating the round knob located under the seat to increase or decrease resistance when reclining.
• Adjustable Headrest: The headrest can be adjusted in height and angle. Gently pull or push the headrest to find your preferred position for neck and head support.
• Dynamic Lumbar Support: The independent lumbar support can be adjusted vertically to align with the natural curve of your lower back. Locate the adjustment mechanism on the back of the chair and slide it up or down.
• 3D Armrests: The armrests offer multiple adjustments:
  • Height Adjustment: Press the button on the side of the armrest and slide it up or down.
  • Forward/Backward Adjustment: Slide the armrest pad forward or backward.
  • Swivel Adjustment: Rotate the armrest pads left or right.
• Retractable Footrest: Pull the footrest out from under the seat when you wish to recline and elevate your legs. Push it back in when not in use.

5. Maintenance

To ensure the longevity and optimal performance of your COLAMY office chair, regular maintenance is recommended.

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the mesh fabric or plastic components.
• Inspection: Periodically check all bolts and screws to ensure they are tight. Re-tighten if necessary.
• Caster Care: Keep the casters free of hair and debris to ensure smooth movement.

6. Troubleshooting

If you encounter any issues with your chair, please refer to the following common troubleshooting tips:

• Chair not adjusting height: Ensure the gas piston is correctly inserted into the base and the seat mechanism. Check that the height adjustment lever is fully engaged.
• Chair wobbles: Verify that all assembly bolts are securely tightened. Ensure the casters are fully inserted into the star base.
• Backrest does not recline or lock: Check the tilt lock lever to ensure it is in the correct position. Adjust the tilt tension knob to ensure it is not too tight or too loose.
• Footrest not extending/retracting smoothly: Inspect the footrest mechanism for any obstructions or debris.
