• 4D Biaxial Adjustable Headrest: The headrest can be adjusted in four dimensions for effective neck support. It rotates 70°, moves 5.5cm front and back, and folds/rotates 70° with 4.5cm up and down adjustment.
• 6D Adjustable Armrests: The armrests offer flexible support with 3" up & down, 1.2" front & back, 1.2" left & right, 70° left & right rotation, 40° rotation, and 6° dynamic support.

• Adjustable Cushion: The seating depth can be adjusted by 1.97" to accommodate different leg lengths, providing a larger area of support.

3. Maintenance

Regular maintenance will ensure the longevity and optimal performance of your Hbada E3 Pro Ergonomic Office Chair.

• Cleaning: Use a soft, damp cloth to wipe down the mesh and frame. Avoid harsh chemicals or abrasive cleaners, as they may damage the materials.
• Mesh Care: For deeper cleaning of the mesh, a mild soap solution can be used. Allow the mesh to air dry completely before use.
• Moving Parts: Periodically check all screws and connections to ensure they are tight. Re-tighten if necessary to maintain stability.
• Casters: Keep the wheels clean from dust and debris to ensure smooth rolling. You may occasionally need to remove hair or lint that gets caught in the casters.

4. Troubleshooting

Here are some common issues and tips for resolving them:

• Lumbar Support Adjustment: The lumbar support has 7 gears. If you experience issues, pull up 6 gears until you hear a click, then pull down 7 gears to unlock. Pull to the bottom to readjust the position.
• Headrest Front/Back Adjustment: The headrest's front and back adjustment does not reset automatically. You need to pull it to the last unlock position. The guide groove can only be fixed after squeezing and unlocking the inner buckle.
• Backrest Height Adjustment: The liftable backrest has a nine-position adjustment. To reset its position, move it up to the ninth gear, and it will automatically return to the lowest level.
• Chair Sinking (Gas Cylinder Issue): If the chair sinks after a few months of use, especially when at maximum height, it may indicate an issue with the gas cylinder. Contact customer service for warranty support.
