Abstract
A person-support surface comprises a non powered mattress and a coverlet positionable on the non powered mattress. The coverlet includes an entry positioned at a first end of the coverlet, an exit positioned at a second end of the coverlet opposite the entry, an upper air impermeable layer, and a lower air impermeable layer coupled to the upper air impermeable layer to form an air flow path along the coverlet between the entry and the exit. The upper air impermeable layer is a vapor permeable and the lower air impermeable layer is a vapor permeable.

10. A person-support surface, comprising:
-
a non powered mattress including a mattress core substantially enclosed within an air and vapor impermeable mattress cover; and a topper removably coupled to the non-powered mattress and including an occupant interfacing surface and a non-powered mattress interfacing surface coupled together to define a chamber therebetween, the occupant interfacing surface and the non-powered mattress interfacing surface being vapor permeable and air impermeable, the topper having a first opening into the chamber along one side of the enclosure and a second opening along another side of the enclosure; and a dedicated air supply in fluid communication with the topper through a conduit, the air entering the chamber though the first opening in the topper, flowing through the chamber, and exiting the chamber through the second opening, the air flow though the topper being configured to exhaust heat and moisture communicated into the chamber through the occupant interfacing surface out through the second opening. - View Dependent Claims (11, 12, 13, 14)
