A temperature controlled drawer assembly incorporates a thermoelectric device and a control system to selectively heat or cool the contents of a drawer which is selectively movable into and out of a cabinet designed to be part of an end table, such as a nightstand, or other cabinet remote from a household kitchen. In a cooling mode of operation, a fan, disposed in the cabinet, draws air from inside the drawer and blows the air over a cold side of a heat sink to cool the air. The treated air is blown through plenums, back into the drawer. At the same time, heat is drawn away from the cold side and directed out of the cabinet. The current through the heat sink may be reversed to flip the cold and hot sides of the heat sink to enable the contents of the drawer to be heated.
