5. Operating Instructions

Your COLAMY Executive Office Ergonomic Chair offers several adjustment options for personalized comfort.

5.1. Seat Height Adjustment

To adjust the seat height, locate the lever on the right side beneath the seat. Pull the lever upwards while seated to lower the seat, or stand up and pull the lever upwards to raise the seat. Release the lever at your desired height.

5.2. Tilt/Rocking Function and Tension Adjustment

To enable the rocking function, pull the lever on the left side beneath the seat outwards. To lock the chair in an upright position, push the lever inwards. The tilt tension knob, located underneath the seat at the front, allows you to adjust the resistance of the rocking motion. Turn clockwise to increase tension (firmer rock) and counter-clockwise to decrease tension (looser rock).

5.3. Adjustable Lumbar Support

The chair features an adjustable built-in lumbar support. Locate the knob/pump on the side of the backrest. Operate this knob to increase or decrease the back pressure to your preferred level, customizing your lower back support.

5.4. Flip-Up Armrests

The armrests are designed to flip up, allowing the chair to be pushed further under a desk or table. Simply lift the armrests upwards to move them out of the way, providing more space or easier storage.

6. Maintenance

Regular maintenance helps prolong the life and appearance of your chair.

• Cleaning: Wipe the bonded leather with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Fasteners: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability.
• Casters: Keep casters clean from debris (hair, dust) to ensure smooth rolling.

7. Troubleshooting

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

• Chair not rising/lowering: Ensure the gas lift lever is fully engaged and the gas lift cylinder is correctly installed in the base and mechanism.
• Chair squeaks: Check and tighten all assembly screws. Lubricate moving parts if necessary.
• Difficulty tilting/rocking: Adjust the tilt tension knob located underneath the seat. Ensure the tilt lock lever is disengaged.
• Lumbar support not adjusting: Check the connection of the pump/knob to the internal bladder. Ensure there are no kinks or leaks in the air hose.
