Abstract
The lumbar roll is particularly usable by a person seated for extensive periods of time, as, for example, a computer operator, to alert the user to various conditions such as poor posture and/or a need to exercise. The lumbar roll includes a piece of foam material surrounded by a zippered casing of nylon or the like. A battery powered electronic unit is encased in the foam material, and a pressure switch is also positioned in the foam material so that the switch is closed by user pressure exerted on the roll. After user pressure closes the pressure switch, the electronic unit turns on and timers are activated to provide an audible alert if the pressure switch should open for a predetermined period of time thereafter to indicate a condition such as poor posture, for example, or if the pressure switch is not opened for a predetermined period of time thereafter to provide a different audible alert of a second condition such as a need for exercise, for example. Automatic shut-off occurs when no pressure is sensed by the detector for a predetermined period of time.
