A warming system, mounted to the foot of a bed, warms a person's lower extremities by directing air into the space between the mattress and overlaying blankets. A blower directs air into an elongated distribution chamber having many tiny exit apertures. The chamber is mounted at the foot of the bed, so that air exiting the apertures warms the person's feet. For maximum thermal transfer, the chamber is placed under the sheet and any blankets, but above the mattress cover and fitted sheet. The chamber may be implemented by a length of open cell foam, a hollow manifold with many punctures or other tiny distribution apertures, collapsible pocket, etc. While the person is lying on the bed beneath the blankets, with feet proximate the foot of the bed, the blower directs temperature-regulated air into the chamber and through the exit apertures, thereby warming the person's feet. A temperature regulator ensures a normothermic air temperature (or alternatively, hyperthermic air temperature.) Thus, the invention helps relieve or prevent “cold feet” by directing normothermic air at a person's lower extremities. Additionally, by applying heat to the feet and legs, the invention encourages blood flow by virtue of sympathetic vasodilation and local temperature-mediated vasodilation. The invention is also believed to prevent some leg and foot ulcers from forming by maintaining the lower extremity at a near normal temperature during sleep.

An improved comfort product that uses an airflow through a heat exchanger and into the comfort product to selectively heat or cool an occupant has a support layer contacting and supporting a channel layer. The channel layer has at least one channel with an opening to accept air. The channel layer contacts and supports an engineered distribution layer that has numerous small holes making it air permeable. The engineered distribution layer contacts and supports an air permeable comfort layer that is of such size and shape to support an occupant of the comfort product. The comfort product also has a heat exchanger assembly for supplying heated or cooled air to the opening in the channel. The heat exchanger assembly includes an air intake having an intake fan, an exhaust outlet and a heat exchanger for selectively heating or cooling air flowing through the heat exchanger resulting in selectively heated or cooled supply air and exhaust air. The intake fan forces air through the heat exchanger where some of the air is selectively heated or cooled to be supplied to the comfort product and some air is used as exhaust air (to remove the unwanted heat if the supplied air is cooled or to warm the exhaust side of the heat exchanger if the supply air is warmed.). The selectively heated or cooled supply air then moves through the channels in the channel layer and the exhaust air exits through the exhaust vent. The selectively heated or cooled supply air then moves through the engineered distribution layer where the numerous small holes diffuse the air and then the selectively heated or cooled air then moves through the comfort layer where the air is further diffused and where the selectively heated or cooled air can selectively heat or cool an occupant of the comfort product.
