1. A mattress for supporting a person, the mattress comprising a cover defining an interior region,a plurality of laterally extending inflatable bladders in the interior region of the cover; andan air distributor located in the interior region of the cover, the air distributor having a plurality of nozzles oriented laterally and through which air is injected into the interior region of the cover outside each of the plurality of laterally extending inflatable bladders, wherein the air distributor comprises at least one duct from which at least some of the plurality of nozzles extend, wherein the at least one duct comprises a first duct situated adjacent a first side of the mattress and a second duct situated adjacent a second side of the mattress. 2. The mattress of claim 1, wherein at least some of the air injected from the nozzles is distributed between the laterally extending inflatable bladders. 3. The mattress of claim 1, wherein the air injected from the nozzles is circulated inside the cover so as to limit the development of dampness inside the cover and at an interface between the cover and a patient. 4. The mattress of claim 1, wherein the air distributor is located within a sacral zone of the mattress. 5. The mattress of claim 1, wherein the at least some of the plurality of nozzles extend in substantial perpendicular relation with the at least one duct. 6. The mattress of claim 1, wherein the air distributor further comprises fastener tabs extending from the at least one duct in a direction opposite to that of the plurality of nozzles. 7. The mattress of claim 1, further comprising a layer of foam and the air distributor being situated above the foam. 8. The mattress of claim 7, wherein the air distributor is situated beneath at least some of the plurality of laterally extending inflatable bladders. 9. A mattress for supporting a person, the mattress comprising a cover defining an interior region,at least one inflatable bladder in the interior region of the cover; andan air distributor located in the interior region of the cover, the air distributor having a plurality of nozzles that are oriented substantially parallel to each other and through which air is injected into the interior region of the cover outside the at least one inflatable bladder, wherein the air distributor comprises at least one duct from which at least some of the plurality of nozzles extend, wherein the at least one duct comprises a first duct situated adjacent a first side of the mattress and a second duct situated adjacent a second side of the mattress. 10. The mattress of claim 9, wherein at least some of the air injected from the nozzles is distributed around the at least one inflatable bladder. 11. The mattress of claim 9, wherein the air injected from the nozzles is circulated inside the cover so as to limit the development of dampness inside the cover and at an interface between the cover and a patient. 12. The mattress of claim 9, wherein the air distributor is located within a sacral zone of the mattress. 13. The mattress of claim 9, wherein the at least some of the plurality of nozzles extend in substantial perpendicular relation with the at least one duct. 14. The mattress of claim 9, wherein the air distributor further comprises fastener tabs extending from the at least one duct in a direction opposite to that of the plurality of nozzles. 15. The mattress of claim 9, further comprising a layer of foam and the air distributor being situated above the foam. 16. The mattress of claim 15, wherein the air distributor is situated beneath the at least one inflatable bladder. 17. A mattress for supporting a person, the mattress comprising a cover defining an interior region,at least one inflatable bladder in the interior region of the cover; andan air distributor located in the interior region of the cover, the air distributor having a plurality of nozzles that are oriented substantially parallel to each other and through which air is injected into the interior region of the cover outside the at least one inflatable bladder, each nozzle of the plurality of nozzles having a tapered shape and terminating at an end that is perforated.
