Operating Instructions
Height Adjustment:
To adjust the seat height, locate the lever under the right side of the seat cushion. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly and pull the lever up. Release the lever at the desired height. The seat height adjusts from 18.5 inches to 22.2 inches from the floor.

Flip-up Armrests:
The armrests can be flipped up to allow the chair to be pushed closer to a desk or for activities requiring more arm movement, such as playing guitar or drawing. Simply lift the armrests upwards until they lock into the vertical position. To lower them, gently pull them down.
