An inflatable mattress capable of being folded or rolled into a small compact unit and unfolded or unrolled to a relatively flat or partially contoured body supporting condition. The mattress is comprised of an inner foam core of the type capable of being rolled or folded. An outer flexible and foldable fabric cover surrounds the foam core. Moreover, air spaces are formed in the foam core to allow a self-inflating when a valve on the mattress is opened. The mattress is air impervious and will remain inflated when the valve is closed. This construction also allows a deflating when the mattress is compressed and the valve is again opened. The mattress is characterized in that the major part of the upper surface area is provided with a plurality of closely spaced apart recesses formed in both the cover and the foam core and thereby define corresponding raised portions or projections between each of the recesses. The projections are relatively closely spaced apart from one another and thereby form a linear upper body supporting surface. In a more preferred embodiment, the raised portions are formed of a polygonal shape, such as a hexagonal shape.
