The present invention is a furniture apparatus that uses an indicator, such as a light, to provide a signal to a user. Power can be provided to the indicator by energy acquisition elements and energy storage elements. The energy acquisition elements and energy storage elements can be combined along with the necessary sensors and switches to allow the user to control the acquisition of energy and whether or not the indicator is activated. For convenience purposes, a carriage housing the energy acquisition elements and energy storage element can be removed from the furniture for acquiring energy in a remote location from the furniture. |
