Operating Instructions
Your COLAMY Executive Chair offers several adjustable features for personalized comfort:
- Seat Height Adjustment:
To raise the seat, lift the lever on the right side of the chair while taking your weight off the seat. To lower the seat, lift the lever while seated. Release the lever at the desired height.

Figure 3: Multi-functional Chair Features. This image highlights various adjustable features including height adjustment, rocking function, and lumbar support.
- Pop-Out Lumbar Support:
Locate the button on the side of the backrest. Gently push this button to extend the lumbar support forward by approximately 3 inches, providing enhanced lower back support. Release the button to retract the support.

- Adjustable Headrest:
The headrest can be adjusted vertically to suit your height and provide optimal neck support. Gently pull up or push down the headrest to your desired position.
- Flip-Up Armrests:
The armrests can be flipped up to allow the chair to be easily stowed under a desk, maximizing space. Simply lift the armrests upwards until they lock into the vertical position. To lower them, pull them down.
- Rocking Function and Tilt Tension:
Pull out the lever on the right side of the chair to enable the rocking function, allowing the chair to recline between 90 and 105 degrees. Push the lever in to lock the chair in an upright position.
Adjust the tilt tension knob located underneath the seat to control the resistance of the rocking motion. Turn clockwise to increase tension (stiffer rock) and counter-clockwise to decrease tension (looser rock).
- Upgraded Casters:
The chair is equipped with upgraded, large-diameter silent casters designed for smooth and effortless movement across various floor types without causing scratches. These casters provide 360-degree rotation for flexible mobility.

Maintenance
Proper care will extend the life of your COLAMY Executive Chair:
- Cleaning: For general cleaning, wipe the leather upholstery with a soft, damp cloth. For spot cleaning, use a mild leather cleaner or follow dry clean instructions if necessary. Avoid harsh chemicals or abrasive cleaners.
- Hardware Check: Periodically inspect all screws and bolts to ensure they are tight. Loose hardware can affect the chair's stability and safety.
- Caster Care: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling. You can periodically remove casters and clean the axles.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the leather to fade or crack. Position the chair away from direct sunlight if possible.
- Avoid Sharp Objects: Prevent sharp objects from coming into contact with the leather to avoid punctures or tears.
Troubleshooting
If you encounter issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles or is unstable. | Loose bolts or uneven assembly. | Ensure all assembly bolts are securely tightened. Check that the chair is on a flat surface. |
| Chair does not adjust height. | Gas lift issue or lever not engaged. | Ensure the height adjustment lever is fully engaged. If the issue persists, the gas lift may need replacement. Contact customer support. |

| Rocking function is too stiff or too loose. | Tilt tension knob needs adjustment. | Adjust the tilt tension knob located underneath the seat. Turn clockwise for stiffer rocking, counter-clockwise for looser rocking. |
| Lumbar support does not pop out/retract. | Mechanism issue. | Ensure the button is fully pressed/released. If the mechanism is stuck or broken, contact customer support. |
