5. Operating Instructions
Your Serta Torrington office chair offers several adjustable features to customize your comfort. Familiarize yourself with these controls for an optimal seating experience.

Height Adjustment: To adjust the chair's height, lift the lever located on the side of the chair. While seated, lift your body slightly to raise the chair, or apply weight to lower it. Release the lever to lock the height.

Recline Adjustment: Pull the lever on the side of the chair outwards to unlock the recline mechanism. You can then lean back to your desired angle. Twist the tension knob (usually located under the seat) to adjust the resistance of the recline. Push the lever inwards to lock the chair in an upright position.

Flip-Up Armrests: The chair features plush padded armrests that can be flipped up and out of the way. This provides space-saving convenience and allows for easier access to your desk or a wider range of motion.

360° Motion Casters: The chair is equipped with smooth-rolling casters that allow for 360-degree rotation and easy gliding across most carpet types and hard surfaces.
6. Maintenance
- Cleaning: The vegan faux leather upholstery can be spot cleaned with a damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Regular Inspection: Periodically inspect all bolts and screws to ensure they are tight. Re-tighten as necessary to maintain the chair's structural integrity.
- Caster Care: Keep the casters free of hair, dust, and debris to ensure smooth movement and prevent damage to flooring.
7. Troubleshooting
- Chair feels unstable: Ensure all assembly screws are securely tightened. Verify the chair is on a flat, level surface.
- Height adjustment not working: Check that the lever is fully engaged or disengaged. Ensure the gas lift cylinder is correctly seated in the base and seat plate.
- Recline not functioning: Confirm the recline lever is pulled out to unlock. Adjust the tension knob to find your preferred recline resistance.
- Casters not rolling smoothly: Inspect casters for any trapped debris (hair, lint, etc.) and clean them thoroughly.
