Operating Instructions

Chair Adjustments

The COLAMY Executive Office Chair offers several adjustable features to customize your seating experience:

• Seat Height Adjustment: Use the lever located under the right side of the seat to raise or lower the chair. Lift the lever while standing to raise the seat. Sit on the chair and lift the lever to lower the seat.
• Rocking Function: The chair features a rocking function that allows movement between 90-110 degrees. Pull the lever out to enable rocking, push it in to lock the chair in an upright position.
• Rocking Pressure Adjustment: Turn the round knob located under the front of the seat to adjust the tension of the rocking mechanism. Turn clockwise to increase tension (firmer rock), counter-clockwise to decrease tension (looser rock).
• Adjustable Built-in Lumbar Support: A knob on the side of the chair allows you to fine-tune the pressure of the lumbar support to match your lower back's contour. Turn the knob to increase or decrease the lumbar support.
• Flip-up Armrests: The armrests can be flipped up to allow the chair to slide further under a desk or for easier entry/exit. Simply lift the armrests upwards until they lock into the vertical position.

Maintenance

To ensure the longevity and appearance of your COLAMY office chair, follow these simple maintenance guidelines:

• Cleaning: Wipe clean with a damp cloth. For bonded leather, use a mild leather cleaner if necessary, and avoid harsh chemicals.
• Inspection: Periodically check all bolts and screws to ensure they are tight. Re-tighten if loose to maintain stability and safety.
• Caster Care: Keep casters free of debris (hair, dust) to ensure smooth rolling.

Troubleshooting

If you encounter any issues with your COLAMY office chair, refer to the following common solutions:

• Chair feels unstable or wobbly: Ensure all assembly bolts are securely tightened. Check that the casters are fully inserted into the base.
• Seat feels like it's sliding forward: Adjust the rocking tension knob to a firmer setting. Ensure you are sitting correctly with your back against the backrest.
• Lumbar support not working or uncomfortable: Verify the lumbar adjustment knob is functioning correctly. Adjust it gradually to find your preferred support level. If it feels too firm, try loosening the adjustment.
• Difficulty adjusting seat height: Check for any obstructions around the gas lift lever. Ensure the gas lift cylinder is properly seated in the base and mechanism plate.
• Armrests not flipping up/down smoothly: Inspect the armrest hinges for any debris or damage. Apply a small amount of silicone lubricant if movement is stiff.
• Squeaking noises: Apply a small amount of lubricant to moving parts, especially where metal components meet, such as the mechanism plate and gas lift.

If problems persist after attempting these solutions, please contact COLAMY customer support.
