Abstract
A device is provided to heat bed covers prior to a person entering the bed on winter nights. This apparatus mounts on a side of the mattress being supported by adjustable elements that extend between the mattress and a box spring. A fan in the apparatus forces room air through an electric heating coil and then through an outlet which directs the air flow between the bed covers.

An apparatus for warming a bed having a mattress covered by a bed covering, said apparatus comprising:
- a housing having an air inlet and an air outlet;
- a heater within the housing;
- a fan within the housing for producing a flow of air from the air inlet through the heater to the air outlet;
- and
- a support adjustably coupled to the housing and adapted to extend under the mattress to hold the housing along an edge of the mattress, wherein the flow of air from the air outlet is directed between the mattress and the bed covering.

An apparatus for warming a bed having a mattress over which a bed covering extends, said apparatus comprising:
- a housing having a bottom wall with an air inlet and a side wall with at least one air outlet, a plurality of pairs of apertures in the side wall wherein the pairs of apertures are stacked vertically;
- a heater within the housing;
- a fan within the housing for producing a flow of air from the air inlet through the heater to the air outlet;
- and
- first and second support legs selectively received in one of the pairs of apertures to adjust and adapted to extend under the mattress to hold the housing along an edge of the mattress, wherein selection of the one pair of apertures in which the first and second support legs are received adjusts a spatial relationship of the housing to the mattress so that the flow of air from the air outlet is directed between the mattress and the bed covering.
