Operating your bExact Comfort Control Adjustments


The ᵇExact 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.


Each of the 12 positions offers a distinctive change in the level of support that is available.

When the point of the Control is aimed furthest ‘away’ from the user (ie – at 9 o’clock), this means that the support is as its minimum level.

By rotating the Control three positions upward so that it is now located at ‘midnight’, this indicates that the support has reached a medium-upper level, with the Comfort Control in a slightly-raised position.

With a rotation forward of three more increments, and with the support now at 3 o’clock, this results in the Comfort Control being at its maximum and most prominent location*.

A final rotation of the Control three further positions – so that the dial is now at 6 o’clock – has the support returned to central location and is now at a medium-lower level.


Please note that the maximum (3 o’clock) positioning provides a significant prominence which may not suit all users.

We therefore recommend that each first-time user starts with each of the three Comfort Controls set at the neutral (9 o’clock) position and then makes gradual adjustments until the desired level of support is achieved.

Please always remember to pull the Comfort Control dial away from the chair back by a small distance, in order to disengage the locking spring before rotating it to the next position.
