ABSTRACT:
An air mattress includes a first inflatable compartment having a length and width, when inflated, sufficient to support a human body. The first compartment is composed of at least two layers of vinyl, one layer of vinyl forming the top of the compartment and the second forming the bottom. A second inflatable compartment extends generally the length and width of the first compartment and is attached to the first compartment through a perimeter seal that is recessed from the periphery of the air mattress. The second compartment is tufted and may also contain a layer of resilient material.
