A therapeutic mattress is provided including an encasing housing a base layer and a patient support layer in a cavity of the encasing. The base layer has a foam base member and foam side panels connected to the base member. The patient support layer is provided above the base layer and has a plurality of sections or zones. In one embodiment the plurality of sections is made of an inflatable component, and another of the plurality of sections is made of a non-inflatable component. In an alternate embodiment, each of the sections contains an inflatable component. In one embodiment, the zones of the patient support surface include a head zone adjacent a head of the mattress, a foot zone adjacent a foot end of the mattress, a seat zone adjacent the head zone, and a knee zone between the seat zone and the foot zone.

What is claimed is: 1. A therapeutic mattress for supporting an entire body of a user in a prone position, comprising: a base layer; a first generally firm and longitudinally extending foam sidewall extending upwards from one side of the base layer, and a second generally firm and longitudinally extending foam sidewall extending upwards from an opposing side of the base layer, the first and second longitudinally extending sidewalls and the base layer defining a well; a patient support layer positioned on the base layer and between the foam sidewalls in the well, the patient support layer having a plurality of separately zoned air cell sections extending from generally the first sidewall to the second sidewall, including a head zone adjacent a head end of the mattress, a foot zone adjacent a foot end of the mattress, and a seat zone between the head zone and the foot zone, wherein the patient support layer in the head zone comprises a first separate and independent non-powered air cell section extending generally from the first sidewall to the second sidewall, wherein the patient support layer in the seat zone comprises a second separate and independent non-powered air cell section extending generally from the first sidewall to the second sidewall, and wherein the patient support layer in the foot zone comprises a third separate and independent non-powered air cell section, wherein each air cell section has a bottom wall adjacent the base layer, wherein each air cell section is independently inflatable and deflatable to independently set and adjust an air pressure of each air cell section, and wherein each air cell section comprises a plurality of individual air cell members fluidly interconnected to be self-equalizing, each of the air cell members having a sidewall extending vertically from a bottom of the air cell member and terminating in a top wall of each air cell member, each air cell having a height extending from the bottom of the air cell member to the top wall of the air cell member, each air cell member of the air cell sections also being independently moveable in a plurality of directions, including the x, y and z directions, and the air cell members in the head, foot and seat zones being separate from the longitudinally extending sidewalls such that the air cell members are free from connection to the longitudinally extending sidewalls to allow the air cell members of the air cell sections in the head zone, foot zone and seat zone to move independently from the longitudinal extending sidewalls; and, a cover having an interior region covering the patient support layer. 2. The therapeutic mattress of claim 1, wherein the base layer comprises a foam bottom member. 3. The therapeutic mattress of claim 1, wherein the separately zoned air cell sections comprises an array of individual air cells arranged in rows across a flexible base. 4. The therapeutic mattress of claim 1, wherein the sidewalls are more rigid than the base layer. 5. The therapeutic mattress of claim 1, wherein the cover comprises a lower encasing connected with a zipper to an upper encasing. 6. The therapeutic mattress of claim 5, wherein the upper encasing comprises a urethane coated spandex. 7. The therapeutic mattress of claim 1, wherein the base layer has a plurality of slices to divide the base layer into discrete sections. 8. The therapeutic mattress of claim 1, further comprising a firm end wall at one end of the base layer. 9. A therapeutic mattress for supporting an entire body of a user in a prone position, comprising: a base member having a bottom and first and second generally firm upstanding longitudinally extending foam side walls connected at opposing sides of the bottom; and, a patient support surface having a head zone adjacent a head end of the mattress and extending from the first side wall to the second side wall, a foot zone adjacent a foot end of the mattress and extending from the first side wall to the second side wall, and a seat zone between the head zone and the foot zone and extending from the first side wall to the second side wall, wherein a foam mattress insert is provided in one of the zones and extends from approximately the first side wall to the second side wall, wherein an air mattress insert is provided in another of the zones and extends from approximately the first side wall to the second side wall, the air mattress insert comprising a plurality of rows and columns of individual air cell members cells fluidly interconnected to be self-equalizing, the air cell members extending vertically from a base of the air cell section and each air cell member being independently moveable in a plurality of directions, and wherein the foam mattress and the air mattress being positionable in any zone. 10. The therapeutic mattress of claim 9, wherein the side walls are more rigid than the foam mattress insert of the patient support. 11. The therapeutic mattress of claim 9, further comprising an encasing covering the base member and the patient support surface, the encasing having a top cover made of a coated stretch material to allow the top cover to be breathable but substantially impervious to water.
