4. Maintenance

Regular maintenance helps prolong the life and appearance of your office chair.

4.1 Cleaning Instructions

• General Cleaning: Wipe clean with a damp cloth. For stubborn spots, use a mild soap solution and a soft cloth, then wipe dry.
• Mesh Fabric: Use a soft brush or vacuum cleaner with a brush attachment to remove dust and debris from the mesh backrest and seat.
• Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or strong detergents, as these can damage the chair's materials.

4.2 Inspection and Tightening

Periodically check all bolts and screws to ensure they are tight. Loose fasteners can affect the chair's stability and safety. Tighten any loose connections using the appropriate tools.

5. Troubleshooting

This section addresses common issues you might encounter with your office chair.

5.1 Chair Sinks or Does Not Hold Height

• Issue: The chair slowly lowers or does not stay at the set height.
• Solution: This typically indicates a worn or faulty gas lift cylinder. Contact customer support for assistance or replacement parts.

5.2 Chair Squeaks or Wobbles

• Issue: The chair makes noise or feels unstable during use.
• Solution: Check all assembly bolts and screws. Tighten any that are loose. Applying a small amount of silicone lubricant to moving parts (e.g., where the gas lift meets the mechanism, or where the base connects to the mechanism) can help reduce squeaking.

5.3 Wheels Do Not Roll Smoothly

• Issue: Casters are stiff or accumulate debris.
• Solution: Turn the chair over and inspect the wheels. Remove any hair, dust, or debris wrapped around the axles. Clean the wheels with a damp cloth.
