Setup and Assembly Instructions

Assembly typically requires two people. Follow these steps for proper chair assembly:

1. Unpack Components: Carefully remove all parts from the packaging and lay them out on a clean, soft surface to prevent scratches. Verify all components are present against the parts list (not provided in this manual, refer to packaging).
2. Attach Casters to Base: Insert the dual-wheel casters into the holes at the end of each leg of the chair base. Push firmly until they click into place.
3. Insert Gas Lift: Place the gas lift cylinder into the center hole of the assembled chair base.
4. Attach Mechanism to Seat: Secure the seat mechanism to the underside of the seat cushion using the provided screws. Ensure the front of the mechanism aligns with the front of the seat.
5. Connect Seat to Gas Lift: Carefully place the assembled seat onto the gas lift cylinder, ensuring it is centered and stable.
6. Attach Backrest to Seat: Align the backrest with the seat and attach it using the designated screws. It is recommended to leave these screws slightly loose initially to allow for easier alignment of the armrests.
7. Install Armrests: Attach the armrests to both the seat and the backrest using the provided screws. Once all armrest screws are in place, tighten all screws for the backrest and armrests securely.

Note:

During armrest installation, ensure all screws are aligned before tightening to prevent stripping. If an armrest bolt repeatedly loosens, applying a thread-locking compound (not included) may help secure it.

Operating Instructions

Your Serta Jackson chair offers several adjustments to customize your seating experience:

Height Adjustment

To adjust the seat height, locate the lever on the right side of the chair (when seated). Lift the lever to raise the seat. To lower the seat, remain seated and lift the lever. Release the lever at your desired height.

Recline and Tilt Tension Adjustment

To unlock the recline mechanism, locate the lever on the left side of the chair (when seated) and lift it. The chair back will then allow you to recline. To lock the recline position, push the lever down.

To adjust the tilt tension, rotate the large knob located underneath the front of the seat. Turning the knob clockwise increases tension, making it harder to recline. Turning it counter-clockwise decreases tension, allowing for easier recline.

Maintenance and Care

Proper care will extend the life and appearance of your Serta Jackson chair:

• Cleaning: The bonded leather upholstery should be spot cleaned only. Use a damp cloth with mild soap and water for spills or stains. Avoid harsh chemicals or abrasive cleaners, as these can damage the material.
• Regular Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten as necessary to maintain stability and prevent wobbling.
• Caster Care: Keep the casters free of debris such as hair or carpet fibers to ensure smooth rolling.

Troubleshooting

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

• Chair Wobbles:
  Solution: Check all assembly screws, particularly those connecting the armrests to the seat and backrest, and the mechanism to the seat. Tighten any loose screws.
• Gas Lift Not Functioning (Chair stuck at one height):
  Solution: Ensure the height adjustment lever is fully engaged or disengaged. If the issue persists, the gas lift cylinder may need replacement. Contact customer support for assistance.
• Casters Not Rolling Smoothly:
  Solution: Turn the chair over and inspect the casters for accumulated hair, dust, or debris. Remove any obstructions.
• Difficulty Reclining or Adjusting Tilt:
  Solution: Verify the recline lever is in the unlocked position. Adjust the tilt tension knob (under the seat) to a looser setting if the recline is too stiff.
• Armrests Feel Loose:
  Solution: Re-tighten the screws securing the armrests. For persistent loosening, a thread-locking compound may be applied to the screw threads (ensure it is safe for plastics if applicable).
