Abstract

A bed can include a mattress and a foot warming system. The mattress can include a mattress cover and a support structure that is positioned under and covered by the mattress cover. The foot warming system can include a heating unit an envelope, a power source, and an electrical connector electrically connecting the heating unit to the power source. The heating unit can be positioned inside the envelope between the envelope top and the envelope bottom. The heating unit and the envelope can be positioned at a foot of the bed under mattress cover between the support structure and the mattress cover.

First claim

1 . - 20 . (canceled)

21 . A pad for a mattress, the pad comprising:
a first layer configured to allow a flow of a fluid through the first layer, thereby removing heat from the pad; and a second layer comprising a heating unit configured to input heat into the second layer, thereby inputting heat to the pad, the second layer and the first layer at least partially overlapping.

22 . The pad of claim 21 , further comprising a temperature controller configured to control the flow of the fluid through the first layer and configured to control the heating unit.

23 . The pad of claim 22 , further comprising a remote control configured to operate the temperature controller responsive to a user input via wireless connection.

24 . The pad of claim 22 , further comprising a user input device wired to the temperature controller, the user input device configured to receive tactile input from a user, and responsive to the tactile input from the user, alter a condition of the pad.

25 . The pad of claim 22 , wherein the temperature controller is configured to operate at different power levels over time, thereby adjustably removing heat from the pad or inputting heat into the pad.

26 . The pad of claim 22 , wherein operating at different power levels over time comprises operating at a high power level in order to initially heat the pad for a first time period, and then, after the first time period, operating at a lower power level to maintain a target temperature of the pad for a second time period.

27 . The pad of claim 22 , further comprising electrical connectors configured to electrically couple the temperature controller to a power source.

28 . The pad of claim 27 , wherein the electrical connectors comprise wires configured to extend along sides of the mattress between the temperature controller and the power source.

29 . The pad of claim 21 , further comprising a fabric cover enveloping the first layer and the second layer, the first layer and the second layer sealed within the fabric cover.

30 . The pad of claim 29 , wherein the fabric cover comprises a top portion and a bottom portion, the top portion a different material than the bottom portion.

31 . The pad of claim 30 , wherein the top portion comprises a breathable mesh.

32 . The pad of claim 30 , wherein the bottom portion comprises a fire resistant material.

33 . The pad of claim 30 , further comprising at least one padding layer.

34 . The pad of claim 33 , wherein the at least one padding layer is in contact with the top portion of the fabric cover.

35 . The pad of claim 33 , wherein the at least one padding layer is contact with at least one of the first layer or the second layer.

36 . The pad of claim 33 , wherein the at least one padding layer at least partially overlaps one of the first layer or the second layer.

37 . The pad of claim 21 , wherein the first layer comprises one or more cooling elements configured to move air through the first layer.

38 . The pad of claim 21 , wherein the heating unit comprises one or more heating elements configured to conduct electricity, thereby input heat into the second layer.

39 . The pad of claim 38 , wherein the one or more heating elements comprise wires.

40 . A pad for a mattress, the pad comprising:
a first layer configured to allow a fluid to flow through the first layer, thereby cooling a portion of the pad; and a heating unit configured to input heat into the pad, thereby heating a portion of the pad, the heating unit and the first layer at least partially overlapping.
