5. Operating Instructions
Your FAMSINGO office chair offers several adjustable features 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 at the desired height.
- Tilt and Lock Function:
The chair features a tilt-tension mechanism and a recline lock. The backrest can recline up to 120°. Pull the lever outwards to enable rocking/tilting. Push the lever inwards to lock the backrest in an upright position (90°). You can also adjust the tilt tension by rotating the round knob located under the seat, allowing you to control the resistance of the recline.

- Flip-Up Armrests:
The armrests can be flipped up to allow the chair to be pushed closer to a desk or for space-saving storage. Simply lift the armrests upwards until they lock into the vertical position. To return them, pull them down.
- Lumbar Support:
The chair's ergonomic design includes a thickened headrest and segmented padded high backrest that conforms to the curve of the human spine, providing strong support and helping to relieve back and lumbar pressure.
- Smooth Rolling Casters:
The 360° swivel casters are designed for smooth movement across various floor surfaces without scratching. Ensure the floor is clear of obstructions for optimal mobility.

6. Maintenance
Proper care will extend the life and appearance of your FAMSINGO office chair.
- Cleaning the PU Leather:
The PU leather is waterproof and resistant to stains. For general cleaning, wipe with a soft, damp cloth. For tougher stains, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.

- Caster Maintenance:
Periodically check the casters for accumulated hair or debris and clean as necessary to ensure smooth rolling.
- Hardware Check:
Every few months, check all screws and bolts to ensure they are still tight. Retighten if necessary to maintain stability and safety.
- Cushion Care:
The chair features a soft and comfortable thick sponge cushion designed not to collapse or deform over time. Avoid placing sharp objects on the cushion.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not raise or lower. | Gas lift cylinder malfunction or lever not engaged. | Ensure the lever is fully engaged. If the issue persists, the gas lift may need replacement. Contact customer service. |
| Chair is wobbly or unstable. | Loose screws or improper assembly. | Check and tighten all assembly screws, especially those connecting the seat, backrest, and armrests to the mechanism plate. Ensure the gas lift is fully seated in the base. |
| Casters do not roll smoothly. | Debris (hair, lint) caught in casters. | Turn the chair over and carefully remove any debris from the caster wheels. |
| Chair squeaks when moving. | Loose connections or friction between parts. | Tighten all screws. Apply a small amount of silicone lubricant to moving parts or connection points if necessary. |
