Bed air control system
A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.
1. A bed comprising:
a mattress comprising:
an inflatable air chamber;

a pump assembly fluidly connected to an end hose end of the first air hose and configured to supply fluid to the inflatable air chamber, wherein the pump assembly is positioned in the foundation; and
an air controller fluidly connected to the second air hose and configured to move air through the air distribution layer, wherein the air controller is positioned in the foundation.
6. The bed of claim 1 , wherein the first air hose is at least partially routed adjacent the second air hose.
7. The bed of claim 1 , wherein the first air hose is at least partially routed together with the second air hose within the mattress.
8. The bed of claim 1 , wherein the air distribution layer includes a layer cover, and wherein the second air hose is fastened to the layer cover to fluidly connect the second air hose with the air distribution layer.
9. The bed of claim 1 , and further comprising:
a foundation having a support platform configured for supporting the mattress and including a first foundation opening extending through the support platform and configured to receive the first and second air hoses.
10. The bed of claim 9 , further comprising:
a hose connector including a base fixed to a top surface of the foundation, and a rib extending from the base away from the top surface of the foundation, the rib configured to be inserted into the second air hose and maintain a width of at least an end of the second air hose against the first air hose running adjacent the second air hose, when the end of the second air hose is connected to the hose connector.
11. The bed of claim 1 , wherein the inflatable air chamber is configured to be inflated and deflated to a selected pressure.
12. A bed comprising:
a mattress comprising:
an inflatable air chamber;
an air distribution layer positioned above the inflatable air chamber;
a foam layer positioned above the air distribution layer and proximate a top of the mattress, wherein the foam layer and the air distribution layer are both configured to allow airflow therethrough, and wherein the air distribution layer resists air flow less than the foam layer;
a first air hose connected to the inflatable air chamber for inflating the inflatable air chamber; and
a second air hose connected to the air distribution layer for moving air through the air distribution layer, wherein the second air hose extends from a location that is lower than the inflatable air chamber, around a first side of the inflatable air chamber, to the air distribution layer above the inflatable air chamber,
wherein the inflatable air chamber comprises a first inflatable air chamber and the air distribution layer comprises first and second air distribution zones, wherein the first inflatable air chamber is positioned under the first air distribution zone, and wherein the mattress further comprising a second inflatable air chamber positioned under the second air distribution zone, and
wherein the mattress further comprises:
a third air hose connected to the second inflatable air chamber for inflating the second inflatable air chamber; and
a fourth air hose connected to the second air distribution layer for moving air through the second air distribution layer, wherein the fourth air hose extends from a second location that is lower than the second inflatable air chamber, around a second side of the second inflatable air chamber, to the second air distribution layer above the second inflatable air chamber.
13. The bed of claim 12 , wherein the mattress further comprises a mattress cover, and wherein the first and second air hoses enter the mattress through a first common hole in the mattress cover and the third and fourth air hoses enter the mattress through a second common hole in the mattress cover.
14. The bed of claim 12 , wherein the mattress further comprises:
a first rail positioned on the first side of the first inflatable air chamber, wherein the first rail defines a first hose passage, and wherein the first and second hoses enter the mattress proximate the first hose passage; and
a second rail positioned on the second side of the second inflatable air chamber, wherein the second rail defines a second hose passage, and wherein the third and fourth hoses enter the mattress proximate the second hose passage.
15. The bed of claim 14 , wherein the first rail includes a first notch that defines the first hose passage, and the second rail includes a second notch that defines the second hose passage.
16. The bed of claim 15 , wherein the first rail and the second rail extend between a head portion and a foot portion of the mattress,
wherein the first and second inflatable air chambers are positioned between the first rail and the second rail,
