• Gas lift cylinder

• Casters (5)

4. Setup and Assembly

Assembly typically takes 30-45 minutes for one person. Having a second person can simplify certain steps, especially when attaching the backrest and armrests.

4.1. Step-by-Step Assembly

1. Attach Casters to Base: Insert each of the five casters into the holes at the end of the star base until they click securely into place.
2. Insert Gas Lift: Place the gas lift cylinder into the center hole of the star base.
3. Attach Mechanism to Seat: Secure the mechanism plate to the underside of the seat cushion using the provided screws. Ensure the front of the mechanism aligns with the front of the seat.
4. Connect Seat to Gas Lift: Carefully place the assembled seat onto the gas lift cylinder.
5. Attach Armrests: Secure the armrests to the sides of the seat cushion using the designated screws. Note that the armrests are adjustable and may require careful alignment during this step.
6. Attach Backrest: Connect the backrest to the seat assembly. The Hbada E1 features a two-stage backrest height adjustment. During assembly, choose between the high or low bolt holes based on your height and preference to fix the backrest. This allows for personalized comfort.
7. Install Headrest: Slide the headrest into the designated slot at the top of the backrest.

5. Operating Instructions (Adjustments)

The Hbada E1 chair offers multiple adjustment options to customize your seating experience for optimal comfort and ergonomic support.

5.1. Seat Height Adjustment

To adjust the seat height, pull the lever located under the right side of the seat upwards. While pulling the lever, lift your body weight off the seat to raise it, or remain seated to lower it. Release the lever to lock the height.

5.2. Lumbar Support Adjustment

The 2D lumbar support can be adjusted vertically by 4.5 cm and rotated by 45 degrees. This allows you to position the lumbar support precisely to match the curve of your lower back, providing targeted support and reducing fatigue.

5.3. Headrest Adjustment

The headrest can be adjusted vertically by 13 cm and rotated by 30 degrees. Adjust the headrest to support your neck and head comfortably, relieving pressure during long periods of sitting.

5.4. Armrest Adjustment

The armrests can be adjusted vertically by 7 cm and rotated by 60 degrees. This allows you to find the ideal position to support your arms and shoulders, preventing strain, whether working or relaxing.

5.5. Reclining Function and Footrest

The chair features a reclining function that allows the backrest to tilt from 110 degrees to a maximum of 145 degrees. Use the lever on the left side of the seat to adjust and lock the recline angle. For enhanced relaxation, extend the integrated footrest. This feature is ideal for short breaks or extended periods of rest.

6. Maintenance

Regular maintenance will help prolong the life and appearance of your Hbada E1 office chair.

• Cleaning: For mesh and fabric surfaces, use a soft cloth dampened with mild soap and water. Avoid harsh chemicals or abrasive cleaners. For the steel base and plastic parts, wipe with a damp cloth.
• Casters: Periodically check casters for accumulated dust or hair and clean them to ensure smooth movement.
• Hardware: Regularly inspect all screws and bolts to ensure they are tight. Retighten as necessary to prevent loosening and potential instability.
• Gas Lift: Avoid exposing the gas lift to extreme temperatures or direct sunlight for extended periods.

7. Troubleshooting

If you encounter any issues with your Hbada E1 chair, refer to the following common problems and solutions:

• Chair Squeaks: Check all bolted connections and tighten any loose screws. Applying a small amount of silicone lubricant to moving parts (e.g., mechanism, gas lift connections) may also help.
• Chair Does Not Stay at Desired Height: This usually indicates an issue with the gas lift cylinder. Ensure the height adjustment lever is fully released. If the problem persists, the gas lift may need replacement.
• Chair Feels Unstable/Wobbly: Verify that all screws are securely tightened, especially those connecting the backrest, armrests, and mechanism to the seat. Ensure the casters are fully inserted into the base.
• Difficulty Reclining/Locking Recline: Check the recline tension knob (if present, usually under the seat) and adjust it. Ensure the recline lock lever is fully engaged or disengaged.

If these solutions do not resolve the issue, please contact customer support.
