The ?Exact chair features three tear-drop Comfort Control adjustments which are used to increase or decrease the level of back-support to suit individual preference.
Each of these controls has 12x incremental positions.
To make the necessary adjustment, please pull the Comfort Control dial away from the side of the chair by a fractional distance (2 millimetres) to release the spring which is holding it in place.
From here, the dial can be freely-rotated a short distance in order to engage with its next locking position.
The best method to understand how to set these three Controls is to think of each dial as a clock face.
By selecting a position between 1 and 12, you will be able to easily remember your personalised setting at each of the three locations.
