Setup and Assembly
Assembly is generally straightforward and can be completed by one person, though a second pair of hands may be helpful for attaching the backrest. An Allen wrench is included for assembly.
- Attach Casters to Base: Insert each of the five casters into the holes at the end of each leg of the 5-star base. Push firmly until they click into place.
- Install Gas Lift: Place the gas lift cylinder into the center hole of the assembled base.
- Attach Mechanism Plate to Seat: Align the mechanism plate with the pre-drilled holes on the underside of the seat cushion. Ensure the front of the mechanism faces the front of the seat. Secure with screws and washers using the provided Allen wrench.
- Connect Seat to Gas Lift: Carefully place the assembled seat cushion onto the gas lift cylinder, ensuring it is centered and stable.
- Attach Armrests: Secure the armrests to the sides of the seat cushion using the appropriate screws and washers. Ensure they are oriented correctly (left and right).
- Attach Backrest: Align the backrest with the mounting points on the armrests and the seat mechanism. Secure with screws and washers. It may be helpful to have another person hold the backrest steady during this step.
- Final Check: Once assembled, sit in the chair to test its stability and functionality. Ensure all connections are secure.

Operating Instructions
Your Youhauchair office chair offers several adjustable features to customize your seating experience for optimal comfort and support.
- Height Adjustment (Pneumatic Control): Locate the lever under the right side of the seat. To raise the chair, lift the lever while taking your weight off the seat. To lower the chair, lift the lever while remaining seated. Release the lever to lock the height.
- Tilt/Rocking Function: The chair features a tilt function allowing the backrest and seat to recline together. To activate, pull the lever (often the same as the height adjustment lever, or a separate one) outwards. Push it inwards to lock the chair in an upright position.
- Tilt Tension Adjustment: A round knob located under the front-center of the seat controls the tension of the rocking mode. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
- Flip-up Armrests: The armrests can be flipped up to allow the chair to slide further under a desk or for easier entry/exit. Simply lift the armrests upwards until they lock into the vertical position. Push them down to return to the horizontal position.
- Swivel Function: The chair is designed with a 360-degree swivel for easy movement and access to your workspace.
- Mute Nylon Casters: The casters are designed for smooth, quiet rolling and are suitable for various floor types without causing damage.

Maintenance
Proper care and maintenance will extend the life and appearance of your Youhauchair office chair.
- Cleaning: The premium PU leather is easy to clean. Simply wipe the chair with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the material.
- Regular Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten any loose fasteners to maintain stability and safety.
- Caster Care: Keep the casters free of hair, dust, and debris to ensure smooth rolling. You can clean them with a damp cloth or by carefully removing any obstructions.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack. Position the chair away from direct sunlight when possible.
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 engaged. If the issue persists, the gas lift may need replacement. Contact customer support. |
| Chair is wobbly or unstable | Loose screws or improper assembly. | Check and re-tighten all assembly screws, especially those connecting the backrest, armrests, and mechanism plate to the seat. Ensure the base and casters are securely attached. |
| Casters do not roll smoothly | Debris caught in casters or damaged casters. | Turn the chair over and remove any hair, dust, or debris from the caster wheels. If casters are damaged, they may need replacement. |
| Recline function is too stiff or too loose | Tilt tension knob adjustment. | Adjust the tilt tension knob located under the seat. Turn counter-clockwise to loosen the recline tension, and clockwise to stiffen it. |
| Squeaking noises | Loose connections or friction between parts. | Tighten all screws. Apply a small amount of silicone lubricant to moving parts or connection points if tightening does not resolve the issue. |
