There is nothing inside the Airlert bed sensor except for a layer of air filled foam. The mat is placed underneath the bed mattress and even works underneath pressure relieving airflow mattresses.
LUsing Airlert technology, the sensor will detect a change in air pressure within the mat as the person begins to get out of bed, making the sensor fast to react.
