A system for monitoring a seated or supine individual includes a system base and a first hinged arm and a second hinged arm on the system base. The first hinged arm and the second hinged arm each have a range of motion from an engaged position to a free position. The system includes an alarm module positioned to recognize a positional change of the first hinged arm and/or the second hinged arm. The alarm module is configured to produce an alarm when one of first hinged arm and second hinged arm are moved from the first position, and is further configured to turn off an alarm when each of first hinged arm and second hinged arm is returned to the first position, and/or in response to instructions from a supervising individual. The alarm is suitable to alert a supervising individual, e.g., nurse, doctor, guardian, etc.
