Abstract
A warning device for the prevention of pressure sores and circulation problems from prolonged inactivity includes a sensor positioned in a pad to detect the weight of a user on the pad. A sitting timer measures the amount of time the user has continuously sat on the pad, and an alarm activated by the warning device when the user has continuously sat on the pad in excess of a first predetermined limit, wherein the alarm includes a visual alarm mechanism, an auditory alarm mechanism, and a sensory alarm mechanism. A standing timer is started when the user's weight is removed from the pad and measuring the amount of time the user has been off of the pad. The alarm is reactivated if the sensor detects the user's weight reapplied to the pad before the standing timer has expired.
