Operating Instructions (Adjustments)
Your Lorell Mid-Back Swivel Mesh Chair offers several adjustment features to optimize your comfort and support.
- Pneumatic Seat-Height Adjustment: Locate the lever on the right side, under the seat. To raise the seat, lift the lever while taking your weight off the seat. To lower the seat, lift the lever while remaining seated. The seat height adjusts from approximately 17 inches to 21 inches from the floor.
- 360-Degree Swivel: The chair is designed to swivel freely 360 degrees for ease of movement and access to your workspace.
- Back-Height Adjustment: To adjust the height of the backrest, loosen the knob located on the back support post, slide the backrest up or down to your desired position, and then retighten the knob.
- Tilt and Asynchronous Three-Lever Control: This chair features an asynchronous three-lever control mechanism for independent adjustment of seat and back angles, as well as tilt lock. Consult the diagram below for specific lever functions.
- Arm Height and Width Adjustment: The armrests can be adjusted in height and width. Locate the buttons or levers on the armrests to unlock and adjust them to your preferred position.

Maintenance
Regular maintenance will help prolong the life and appearance of your chair.
- Cleaning: For general cleaning, wipe surfaces with a soft, damp cloth. For the mesh back and seat, spot clean only. Avoid harsh chemical cleaners that may damage the fabric or finish.
- Fasteners: Periodically check all screws and bolts to ensure they are tight. Loose fasteners can affect the chair's stability and safety.
- Casters: Keep casters free of debris (hair, dust, etc.) to ensure smooth rolling.
- Moving the Chair: When moving the chair, lift it rather than dragging it to prevent damage to the casters or base.
Troubleshooting
If you encounter issues with your chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height | Gas lift cylinder malfunction or lever not engaged. | Ensure the height adjustment lever is fully engaged. If the issue persists, the gas lift may need replacement. |
| Backrest slips down or does not stay in position | Back-height adjustment knob is loose or mechanism is faulty. | Tighten the back-height adjustment knob securely. If the problem continues, the internal locking mechanism may be worn. |
| Chair feels unstable or wobbly | Loose fasteners or uneven assembly. | Check and tighten all screws and bolts, especially those connecting the seat, back, and armrests to the mechanism and base. Ensure the chair is on a level surface. |
| Casters do not roll smoothly | Debris caught in casters or damaged casters. | Remove any hair, dust, or debris from the caster wheels. If casters are damaged, they may need replacement. |
