3. Maintenance

Proper maintenance will extend the life and performance of your SMUG Ergonomic Office Chair.

• Cleaning: Wipe clean with a soft, damp cloth. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the mesh fabric and other components.
• Fasteners: Periodically check all screws and bolts to ensure they are tight. Loose fasteners can affect the chair's stability and functionality.
• Casters: Regularly clean the casters to remove any accumulated dust, hair, or debris that could impede smooth movement.
• Mesh Fabric: The high-quality mesh is designed for durability and breathability. Avoid sharp objects that could snag or tear the mesh.

4. Troubleshooting

If you encounter any issues with your SMUG Ergonomic Office Chair, refer to the following common troubleshooting tips:

• Chair Not Raising/Lowering: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement. Contact customer support for assistance.
• Squeaking Noises: Check and tighten all visible screws and bolts. A small amount of silicone-based lubricant can be applied to moving parts if tightening does not resolve the issue.
• Instability or Wobbling: Verify that all assembly bolts are securely tightened, especially those connecting the base, seat, and backrest. Inspect the 5-star base and casters for any damage.
• Discomfort or Poor Support: Re-adjust the seat height, tilt angle, armrest positions, and headrest height/angle to find the optimal ergonomic configuration for your body. Ensure the dynamic lumbar support is properly aligned with your lower back.
• Missing Parts: If any parts are missing upon unboxing, please contact SMUG customer support immediately with your purchase details.
