Step 5: Adjust Seat Height
To adjust the seat height, pull the lever located under the seat upwards. The seat will rise when you lift your weight, and lower when you apply weight.

Step 6: Lowering Seat Height
When lowering the seat height, please make sure to sit fully on the seat to apply enough pressure to the gas lift mechanism.

Maintenance and Care
Velvet Care
Vacuum your velvet piece monthly to keep it looking new. Use a nylon brush to remove dirt or food. For a deep clean, contact a professional annually.

Preventative Care
Rotate pillows and cushions monthly for even wear. Avoid placing the chair in direct sunlight to prevent fading. Consider using a slipcover; most are machine-washable and can change your style.
