Operating Instructions
Height Adjustment
To adjust the seat height, lift the lever located on the right side of the chair (when seated) upwards. While holding the lever, either stand up to raise the seat or remain seated to lower it. Release the lever to lock the height in place.

Recline Adjustment
To unlock the recline mechanism, pull the same lever (on the right side) outwards. The chair back will now allow for a rocking motion. To lock the chair in an upright position, push the lever inwards. To adjust the tension of the recline, twist the round knob located underneath the seat at the front of the mechanism. Turn clockwise to increase tension (stiffer recline) and counter-clockwise to decrease tension (looser recline).

Maintenance and Care
To maintain the appearance and longevity of your Serta Comfort Ergo Executive Office Chair, follow these care instructions:
- Cleaning: Wipe clean with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners, as they may damage the velvet fabric.

- Avoid Direct Sunlight: Prolonged exposure to direct sunlight may cause the fabric to fade.
- Weight Limit: Adhere to the maximum weight recommendation of 275 lbs to prevent structural damage.
Troubleshooting
If you encounter any issues with your chair, consider the following:
- Chair feels wobbly: Check all assembly screws and bolts. Ensure they are fully tightened.
- Gas lift not adjusting: Ensure the height adjustment lever is fully engaged or disengaged as required. If the issue persists, the gas lift may need replacement.
- Casters not rolling smoothly: Check for debris (hair, lint) caught in the caster wheels. Clean as necessary.
- Recline not working: Ensure the recline lock lever is disengaged. Adjust the tension knob if the recline feels too stiff or too loose.
