5. Operation and Adjustments
Your Royal II Executive Office Chair offers several adjustment features for personalized comfort.
5.1. Seat Height Adjustment
- To raise the seat: While seated, lift the right lever (typically located under the seat on the right side) and slightly lift your weight off the seat. The seat will rise. Release the lever at the desired height.
- To lower the seat: While seated, lift the right lever. The seat will lower under your weight. Release the lever at the desired height.
5.2. Tilt and Recline Function
- Recline Angle (90-135°): Pull the left lever (typically under the seat on the left side) outwards to unlock the recline function. Lean back to the desired angle (between 90 and 135 degrees). Push the lever inwards to lock the backrest in position.
- Rocking Function: When the recline is unlocked, the chair can rock back and forth. Adjust the tilt tension knob (located under the seat, usually at the front) to control the resistance of the rocking motion. Turn clockwise to increase tension, counter-clockwise to decrease.

6. Care and Maintenance
Proper care will extend the life and appearance of your office chair.
- Cleaning: The silicone leather upholstery is stain-resistant and easy to clean. For general cleaning, wipe the surface with a soft, damp cloth. For spot cleaning, use a mild soap solution and a soft cloth, then wipe dry. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect all moving parts, bolts, and connections. Tighten any loose fasteners to maintain stability and safety.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the upholstery to fade or crack.
- Weight Distribution: Distribute your weight evenly on the chair to prevent undue stress on components.
7. Troubleshooting
If you encounter issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles or feels unstable | Loose bolts or connections. | Inspect and tighten all assembly bolts, especially those connecting the seat to the mechanism and the backrest. |
| Seat 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 cylinder may need replacement. Contact customer service. |
| Backrest does not recline or lock | Recline lever not engaged or mechanism obstruction. | Ensure the recline lever is pulled out to unlock or pushed in to lock. Check for any obstructions under the seat mechanism. |
| Squeaking noises | Loose connections or friction between parts. | Tighten all bolts. Apply a small amount of silicone lubricant to moving parts if necessary, avoiding upholstery. |
