Care and Maintenance

How to Clean

It is recommended that the office chair be thoroughly cleaned at least once a month to maintain condition and functionality.

• Use a vacuum cleaner to suck up the dirt that may be resting on the seat.
• The casters will stick if not maintained regularly. Brush the casters with water and wipe clean with a damp cloth. If dirt solidifies on the surface of the casters, use soap and water to clean it off.
• Use a dry cloth to finish cleaning, or leave your office chair in a ventilated area to air dry.

Maintenance Tips

• Direct sunlight can ruin an office chair over time, degrading most fabrics and materials. Keep your office chair out of direct sunlight.
• Humid conditions may lead to the formation of mildew on fabric and/or rust on metal parts. Do not keep your office chair in a damp environment.
• Be careful with drinks, food, or any type of liquids when you are near your chair. If a spill happens, clean and attend to stains immediately.
• Avoid the use of sharp objects or blades near the office chair that may cause damage.
• If possible, cover the chair to protect it from dirt and dust.
• Regularly examine the chair to ensure that all nuts and bolts are correctly fastened, including those connecting the seat, back, and chair mechanics.
• Retighten bolts every 6 months by using the included Allen key.
• Using an electric drill can damage the chair. Only use hand tools. ❌
