According to certain arrangements, a conditioner mat for use with a bed assembly includes an upper layer comprising a plurality of openings, a lower layer being substantially fluid impermeable, at least one interior chamber defined by the upper layer and the lower layer and a spacer material positioned within the interior chamber. In one embodiment, the spacer material is configured to maintain a shape of the interior chamber and to help with the passage of fluids within a portion of interior chamber. The conditioner mat additionally includes an inlet in fluid communication with the interior chamber, at least one fluid module comprising a fluid transfer device and a conduit placing an outlet of the at least one fluid module in fluid communication with the inlet. In some arrangements, the fluid module selectively delivers fluids to the interior chamber through the conduit and the inlet. In one embodiment, fluids entering the chamber through the inlet are generally distributed within the chamber by the spacer material before exiting through the plurality of openings along the upper layer. The conditioner mat can be configured to releasably secure to a top of a bed assembly.

The conditioner mat of claim 1, wherein the at least one spacer material comprises spacer fabric. 6. The conditioner mat of claim 1, wherein the first chamber comprises a spacer material and the second chamber comprises a generally fluid impermeable member, said second chamber being configured to not receive fluid from the at least one fluid module. 7. The conditioner mat of claim 6, wherein the generally fluid impermeable member comprises a foam pad. 8. The conditioner mat of claim 6, additionally comprising a third chamber, said third chamber comprising a spacer material and being configured to receive fluid, wherein the second chamber generally positioned between the first and third chambers, and wherein the generally fluid impermeable member in the second chamber provides thermal insulation between the first and third chambers. 9. The conditioner mat of claim 1, wherein both the first and second chambers comprise a spacer material, wherein both the first and second chambers are configured to receive fluid, and wherein the upper layer in each of the first and second chambers comprises a plurality of openings. 10. The conditioner mat of claim 9, wherein the at least one fluid module comprises a first fluid module and at least a second fluid module, said first fluid module being in fluid communication with the first chamber and said second fluid module being in fluid communication with the second chamber. 11. The conditioner mat of claim 1, wherein the conditioner mat comprises a skirt portion configured to releasably secure to a mattress or other support structure of a bed like a fitted sheet. 12. The conditioner mat of claim 1, wherein the at least one fluid module is at least partially contained within a fluid box, said fluid box being configured for attachment to a bed assembly. 13. The conditioner mat of claim 1, wherein the at least one fluid module is configured to hang along a side and below of the conditioner mat. 14. The conditioner mat of claim 1, wherein the conduit is insulated to reduce the likelihood of thermal losses. 15. The conditioner mat of claim 1, wherein the spacer material is generally positioned in locations that are likely to be adjacent to targeted high pressure contact areas with an occupant. 16. The conditioner mat of claim 1, wherein the conditioner mat is configured to be positioned on top of a mattress, pad or other support member of a bed assembly, said mattress, pad or other support member comprising softness and structural characteristics that facilitate pressure redistribution for an occupant positioned thereon. 17. The conditioner mat of claim 16, wherein the mattress, pad or support member comprises at least one of foam, gel or a plurality of fluid-filled chambers. 18. The conditioner mat of claim 1, wherein the conduit is at least partially incorporated within a guard rail of a bed assembly. 19. The conditioner mat of claim 1, wherein the conditioner mat is configured to be secured on top of a medical bed. 20. The conditioner mat of claim 1, further comprising at least one sensor. 21. The conditioner mat of claim 20, wherein the at least one sensor comprises at least one of a condensation sensor, a humidity sensor, an occupant-detection sensor, a pressure sensor, a noise sensor and a temperature sensor. 22. A topper member for use with a medical bed, comprising: an enclosure defining at least one fluidly-distinct interior chamber and having substantially fluid impermeable upper and lower layers; said upper layer comprising a plurality of openings through which fluid from the at least one fluidly-distinct interior chamber can exit;at least one securement device for at least temporarily securing the topper member to a medical bed;at least one spacer material positioned within the at least one fluidly-distinct interior chamber, said at least one spacer material configured to maintain a desired separation between the upper and lower layers and to help distribute fluid within the at least one fluidly-distinct chamber;at least one fluid module comprising a fluid transfer device;a conduit placing an outlet of the at least one fluid module in fluid communication with the at least one fluidly-distinct interior chamber;wherein the fluid module selectively delivers fluids to the at least one fluidly-distinct interior chamber through the conduit;wherein fluids entering the at least one fluidly-distinct interior chamber are generally distributed within said at least one interior chamber by the at least one spacer material before exiting through the plurality of openings along the upper layer; andwherein the enclosure defines a first fluidly-distinct chamber and at least a second fluidly-distinct chamber, said first fluidly-distinct chamber being configured to receive fluid having a first temperature from a first fluid module, and said second fluidly-distinct chamber being configured to receive fluid having a second temperature from a second fluid module, wherein the first temperature is greater than the second temperature. 23.
