Headrest Requirements
Suitable headrests must have a fairly hard foam density and a large
enough flat or almost flat surface space to accommodate the full size of
the Headrest Sensor in its pouch. It can be mounted on the outside of
the headrest or placed under the removable cover of the wheelchair's
headrest. The removable cover must be a tight fit around the headrest
foam to ensure the sensor is snug and tight between the surfaces to stop
it from moving and keep it secure.
An example of the ideal shape of the headrest:
