Active airflow temperature controlled bedding systems
View Patent ↗A climate controlled bedding system includes at least one coil spring layer; and an air supply fluidly coupled to the one or more fluid conduits. In some embodiments, a filter is disposed within a flow path of a fluid conduit.
1. A climate controlled bedding assembly comprising:
a base comprising a cavity, the base having a rigid fluid permeable surface enclosing the cavity, wherein the rigid fluid permeable surface is breathable in its entirety such that upward flow of air passes therethrough;
an air supply device disposed within the cavity and in fluid communication with the perforations of the rigid fluid permeable surface of the base;
a perforated foam layer overlaying the base including a plurality of vertically oriented channels extending from a bottom planar surface to a top planar surface, wherein the vertically oriented channels are periodically spaced about an entire surface area of the perforated foam layer;
a coil spring layer overlaying the perforated foam layer, wherein the coil spring layer is in direct contact with the top planar surface of the perforated foam layer; and
an uppermost foam layer overlaying the coil spring layer, the uppermost foam layer including a support surface adapted to substantially face a user resting on the bedding system.
2. The climate controlled bedding system of claim 1 , wherein the coil spring layer comprises pocketed coil springs.
3. The climate controlled bedding system of claim 1 , wherein the air supply device is selected from the group consisting of a fluid transfer device, a thermoelectric device, a convective heater, a heat pump, a dehumidifier and combinations thereof.
4. The climate controlled bedding system of claim 1 , wherein the base defines a foundation for supporting a mattress, and wherein the mattress comprises the perforated foam layer, the coil spring layer; and the uppermost the foam layer including the support surface.
5. The climate controlled bedding system of claim 1 , further comprising a filter intermediate the air supply device and the rigid fluid permeable surface of the base.
6. The climate controlled bedding system of claim 1 , wherein the perforated foam layer comprises a plurality of openings extending from a bottom surface to a top surface.
7. The climate controlled bedding system of claim 1 , wherein the rigid fluid permeable surface is a wire mesh.
8. The climate controlled bedding system of claim 1 , wherein the rigid fluid permeable surface is a perforated support.
9. The climate controlled bedding system of claim 1 , wherein the foam side rail is perforated.
