Clear the garage area so it is a large empty room, removing any stored items. Clean the floor of any dust and debris.
Place the large rug in the center of the garage floor; this will cover the concrete flooring so it is more comfortable to walk on.

Put the TV on the entertainment center and plug it in.
Put the table lamp on top of the entertainment center and plug it into the extension cord or outlet.
Place the sofa in front of the entertainment center. Leave enough room in between the two to place the coffee table and to allow for easy navigation.
Place the coffee table in between the sofa and the entertainment center. Leave space for leg room between the sofa and the table.
Position the space heater or air conditioning unit in an out of the way area near the electrical outlet to regulate the temperature of the garage.
