Safety Information
This chair has a maximum weight capacity of 400 lbs. Exceeding this limit may result in damage to the chair or personal injury. Always ensure all components are securely fastened before use. Avoid standing on the chair or using it for purposes other than intended seating. Improper use of adjustable features, such as the flip-up armrests and synchro-tilt function, could lead to instability or injury. Always follow the assembly instructions and guidelines for safe operation.
Setup and Assembly
Carefully unpack all components and ensure all parts are present before beginning assembly. Refer to the included hardware list to identify each part. Assembly typically requires one person and takes approximately 20-30 minutes.
Assembly Steps
- Base Assembly: Insert the casters into the base. Place the gas lift cylinder into the center hole of the base.
- Seat Attachment: Push the seat part down onto the finished base firmly until the connection is secure.
- Armrest Installation: Attach the two armrests to the seat cushion. Align the screw holes on the arms with the seat cushion. Use two bolts for each side and tighten them to 50% initially with the provided wrench. Ensure arms are marked "L" (left) or "R" (right) for correct placement.
- Backrest Attachment: Secure the backrest to the seat assembly using the appropriate bolts. Ensure all connections are aligned before fully tightening.
- Final Tightening: Once all components are loosely assembled, gradually tighten all bolts to secure the chair. Do not overtighten.

Operating Instructions
Your COLAMY office chair offers several adjustable features to customize your seating experience for maximum comfort and ergonomic support.
1. Seat Height Adjustment
To adjust the seat height, pull the lever located under the right side of the seat upwards. While holding the lever, stand up to raise the seat or remain seated and apply pressure to lower it. Release the lever at your desired height. The adjustable height ranges from 19.3 to 23.2 inches.

2. Synchro-Tilt Function and Tension Adjustment
The chair features a synchro-tilt mechanism allowing the backrest and seat to recline together. To activate the tilt, pull the lever on the left side of the seat outwards. To lock the chair in an upright position, push the lever inwards. The rocking motion can be adjusted between 90-110 degrees.
Adjust the tilt tension by rotating the round knob located under the front of the seat. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).

3. Flip-Up Armrests
The armrests can be flipped up and locked into an upright position, allowing the chair to be stored under most desks, saving space. Simply lift the armrests upwards until they click into place. To lower them, gently pull them down.

4. Ergonomic Design
The chair's backrest curve is designed to align with the natural human body curve, providing ergonomic support for extended periods of sitting. This design promotes proper posture and reduces strain.

Maintenance
Regular maintenance helps prolong the life and appearance of your COLAMY office chair.
- Cleaning: Wipe clean with a damp cloth. For tougher stains on the PU leather, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all bolts and screws to ensure they are tight. Retighten if necessary to maintain stability and safety.
- Casters: Keep casters free of debris (hair, dust, etc.) to ensure smooth movement.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack.
Troubleshooting
If you encounter any issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height | Gas lift cylinder malfunction or lever not engaged. | Ensure the height adjustment lever is fully pulled. If the issue persists, the gas lift cylinder may need replacement. Contact customer support. |
| Chair wobbles or feels unstable | Loose bolts or uneven assembly. | Check and tighten all assembly bolts, especially those connecting the seat, backrest, and armrests to the mechanism. Ensure the chair is on a flat surface. |
| Casters do not roll smoothly | Debris caught in casters or damaged casters. | Remove any hair, dust, or debris from the caster wheels. If casters are damaged, they may need replacement. |
| Backrest does not recline or lock | Tilt mechanism locked or tension too high. | Ensure the tilt lock lever is disengaged (pulled outwards). Adjust the tilt tension knob counter-clockwise to reduce tension. |
If these solutions do not resolve the issue, please contact COLAMY customer support for further assistance.
