A warning device to warn a sedentary patient when the patient has been sitting for too long, the warning device comprising:

• a pad shaped to be positioned to be sat on by the sedentary patient;
• a sensor positioned in the pad to detect the weight of the sedentary patient on the pad;
• a sitting timer measuring the amount of time the sedentary patient has continuously sat on the pad;
• an alarm activated by the warning device when the sedentary patient 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 sufficient to warn the patient;
• and
• a standing timer 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, wherein the alarm is reactivated if the sensor detects the user's weight reapplied to the pad before the standing timer has expired;
