Operating Instructions

Your BOSMILLER Executive Office Chair is equipped with several adjustable features to customize your seating experience for maximum comfort and ergonomic support.

1. Height Adjustment:

To adjust the chair's height, locate the lever on the right side beneath the seat. While seated, lift the lever to lower the chair. To raise the chair, stand up and lift the lever. Release the lever to lock the height in place.

2. Tilt and Rocking Function:

The chair features a 90°-110° tilt and rocking function. To enable rocking, pull the same lever used for height adjustment outwards. To lock the chair in an upright position, push the lever inwards. The tension of the rocking mechanism can be adjusted by turning the round knob located at the front underside of the seat. Turn clockwise to increase tension (stiffer rock) and counter-clockwise to decrease tension (looser rock).

Maintenance

Proper care and maintenance will extend the life and appearance of your BOSMILLER Executive Office Chair.

• Cleaning: Wipe the leather surface with a soft, damp cloth. For tougher stains, use a mild soap solution and immediately wipe dry. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check all bolts and screws to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
• Caster Care: Keep the rubber casters clean from debris (hair, dust) to ensure smooth movement and prevent scratching floors.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the leather to fade or crack.

Troubleshooting

If you encounter any issues with your chair, please refer to the following common solutions:

• Chair Sinks or Won't Stay Up: This usually indicates an issue with the gas lift cylinder. Contact customer support for a replacement.
• Chair Wobbles: Ensure all assembly bolts are securely tightened. Check the base and casters for any damage or loose connections.
• Casters Not Rolling Smoothly: Inspect casters for trapped debris (hair, lint) and clean them thoroughly. Ensure they are properly inserted into the base.
• Backrest Does Not Recline/Rock: Check the tilt lock lever and the tension knob. Ensure the lever is pulled out to enable rocking and adjust the tension knob to your preference.
