4. Setup (Assembly Instructions)

- Insert Gas Lift: Place the gas lift cylinder into the center hole of the chair base.
- Attach Mechanism Plate to Seat: Align the mechanism plate with the screw holes on the underside of the seat cushion. Ensure the front of the mechanism faces the front of the seat. Secure with screws using the provided Allen wrench.
- Attach Armrests to Seat: Secure the armrests to the sides of the seat cushion using the designated screws. Ensure they are firmly attached.
- Attach Backrest to Seat/Mechanism: Connect the backrest to the seat and/or mechanism plate using the appropriate screws. Ensure all connections are tight.
- Connect Seat Assembly to Gas Lift: Carefully place the assembled seat onto the gas lift cylinder, ensuring it is centered and stable.
Once assembled, sit on the chair to firmly seat the gas lift into the base and mechanism.
5. Operating Instructions (Adjustments)
The COLAMY H6 chair offers multiple adjustments for personalized comfort:
- Seat Height Adjustment: Locate the lever on the right side under the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while seated. Release the lever to lock the height.
- Seat Depth Adjustment: This chair features a wire-controlled sliding seat. Locate the control on the left side under the seat. Pull the control to slide the seat forward or backward by up to 2 inches. Release the control to lock the seat depth.
- Backrest Height Adjustment & Lumbar Support: The backrest height can be adjusted by 2.5 inches. While seated, grasp the backrest and lift it upwards to adjust. The synchronous lumbar support will adjust with the backrest height.
- Recline and Lock Function: Use the wire control on the right side under the seat. Pull the control to unlock the recline function. Lean back to your desired angle (95°, 100°, or 120°) and release the control to lock it in place.
- Tilt Tension Adjustment: The round knob located under the front of the seat controls the tilt tension. Turn clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).
- Armrest Height Adjustment: Press the button on the side of each armrest and slide the armrest up or down to your preferred height. Release the button to lock.

6. Maintenance
- Cleaning: For general cleaning, wipe the chair with a soft, damp cloth. For spot removal on the mesh or upholstered parts, use a mild fabric cleaner and blot the area gently. Avoid harsh chemicals or abrasive cleaners.
- Regular Checks: Periodically inspect all screws, bolts, and connections to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Caster Care: Keep casters free of hair and debris to ensure smooth movement.
7. 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 not engaged or faulty | Ensure the height adjustment lever is fully engaged. If the issue persists, the gas lift may need replacement. |
| Chair wobbles or feels unstable | Loose screws or uneven assembly | Check and tighten all screws and bolts. Ensure the chair is assembled on a flat surface. |
| Casters do not roll smoothly | Debris in casters or damaged casters | Remove any hair or debris from the caster wheels. If damaged, casters may need replacement. |
