an inlet in fluid communication with the least one interior chamber;

at least one fluid module comprising a fluid transfer device, the at least one fluid module being in fluid communication with the inlet;

wherein the at least one fluid module selectively delivers fluid to the at least one interior chamber through the inlet;

wherein fluid entering the at least one interior chamber through the inlet is generally distributed within said at least one interior chamber before exiting through the upper layer;

wherein the conditioner mat is configured to be positioned on a bed assembly; and

wherein the upper and lower layers are configured to form at least one fluid boundary, the at least one fluid boundary at least partially fluidly separating adjacent zones of the at least one interior chamber.

2. The conditioner mat of claim 1 , wherein the at least one fluid module comprises at least one thermal conditioning device for selectively thermally conditioning a fluid being delivered to the at least one interior chamber.

3. The conditioner mat of claim 1 , wherein the at least one spacer material comprises spacer fabric.

4. The conditioner mat of claim 1 , wherein the adjacent zones are in fluid communication with each other.

5. The conditioner mat of claim 1 , wherein the adjacent zones of the at least one interior chamber comprise a first zone and a second zone, wherein the first zone comprises a spacer material and the second zone comprises a generally fluid impermeable member, said second zone being configured to not receive fluid from the at least one fluid module.

6. The conditioner mat of claim 5 , wherein the generally fluid impermeable member comprises a foam pad.

7. The conditioner mat of claim 4 , wherein each of the adjacent zones comprises a spacer material, wherein both the first and second zones are configured to receive fluid from a single fluid module.

8. The conditioner mat of claim 1 , wherein the conditioner mat is configured to secure to a mattress or other support structure of a bed.

9. 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 in fluid communication with the inlet of the conditioner mat using at least one fluid conduit.
