Abstract: The present invention is a bed warming device that safely and effectively warms the interior space between the fitted sheet and the top sheet of a bed. The bed warming device includes a heating element similar to those used in hair dryers. The device includes a suction member that suctions ambient air to be heated and delivers it through a narrowing portion that increases the pressure of the heated air. The pressurized, heated air is then expelled to preselected locations of the bed using a plurality of openings located throughout the perimeter of the device's T-shaped hot air delivery assembly. The hot air delivery assembly can include raised portions configured to create a space between the openings and the top bed sheet, thereby maintaining efficient air flow.
