5. Care & Maintenance

• Cleaning: Wipe the chair's frame with a soft, damp cloth. For the mesh and fabric parts, use a mild soap solution and a soft brush, then wipe clean with a damp cloth and allow to air dry. Avoid harsh chemicals.
• Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
• Movement: If the casters become stiff, clean them and apply a small amount of silicone-based lubricant.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause fading and degradation of materials.

6. Troubleshooting

• Chair Squeaks: Check all screws and bolts for tightness. Apply a small amount of silicone lubricant to moving parts if the squeaking persists.
• Gas Lift Not Functioning: Ensure the height adjustment lever is fully engaged or disengaged. If the issue persists, the gas lift may need replacement.
• Chair Feels Unstable: Verify that all assembly screws are securely tightened and that the casters are fully inserted into the base.
• Difficulty Adjusting Recline: Check the tension knob under the seat. Loosen it to make reclining easier, or tighten it for more resistance.
