Positioning the articulating headrest properly to support the head
in its natural relationship to the spine reduces tension in the neck
and jaw muscles decreasing the request for “open wider please”.
The headrest can be used to accommodate wheelchair patients.
NOTE: The use of disposable headrest covers are
recommended to prevent soiling of the headrest.
STEP 1: While in upright position fully depress the release
mechanism on the right and adjust headrest to match
patient’s height.(FIG. 3).
STEP 2: Articulate the headrest cushion to contact the back
of patient’s head.
STEP 3: Recline patient. If necessary, using the release
mechanism, fine tune headrest position (FIG. 4).
STEP 1: Slide the headrest up until it is free from the chair.
Turn the headrest 180°.
STEP 2: Slide the reversed headrest back into the backrest
and push it all the way down.

headrest height by moving the chair up or down (using the
