Abstract:
A mattress, comprising:A. a first chamber defined by a first top surface, a first bottom surface, and a first sidewall connecting the first top surface and the first bottom surface such that the first chamber defines a first interior;B. a first portal in fluid communication with the first chamber that is movable between an open position to allow fluid to move into or out of the first chamber and a closed position to make the first chamber substantially pressure-tight;C. a baffle having a plurality of apertures therethrough connected to the first chamber within the first interior and extending between the first top surface and the first bottom surface;D. a second chamber that is:i. defined by a second top surface, a second bottom surface, and a second sidewall connecting the second top surface and the second bottom surface,ii. connected to at least a portion of the first sidewall, andiii. positioned adjacent at least two opposing portions of the first sidewall; andE. a second portal in fluid communication with the second chamber that is movable between an open position to allow fluid to move into or out of the second chamber and a closed position to make the second chamber substantially pressure-tight; in which a first fluid pressure in the first chamber may be controlled independently of a second fluid pressure in the second chamber.
