Abstract:
An inflatable mattress system comprising:an inflatable mattress of a material that is substantially impermeable to water vapor and can support the weight of a human being thereon by containment of air therein, said mattress having longitudinal and lateral ends defining a perimeter thereof; a breathable fill sheet overlying the mattress, said fill sheet permitting the passage of air and water vapor therethrough; a top sheet having a perimeter overlying the fill sheet, said top sheet being of a material that permits the passage of air or water vapor therethrough, but that blocks the passage of liquid water therethrough; at least a portion of said top sheet being permanently bonded to at least a portion of the perimeter of the mattress so that when a person lies on the mattress system, water vapor between the person and the top sheet can pass through the top sheet and through the fill sheet to a portion of the support mattress displaced from the person lying thereon.
