An air mattress includes a first inflatable compartment having a length and width, when inflated, sufficient to support a human body. The first compartment having a top, a bottom, and sides and 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 is disposed on the top of the first inflatable compartment and is secured to the first compartment along a portion of the first inflatable compartment. The second compartment extends generally the length and width of the top of the first compartment and is of a size, when inflated, sufficient to support a human body. The second compartment is composed of at least two layers of vinyl distinct from the two layers of vinyl forming the first compartment. The second compartment is inflatable to give the top of the air mattress a soft, pillow-like appearance and feel.

What is claimed is: 1. An air mattress comprising: a first inflatable compartment having a length and width, when inflated, sufficient to support a human body, said compartment also having a height when inflated, said compartment having a top, a bottom, and substantially straight, vertically extending sides, said first compartment being composed of at least two layers of vinyl, one layer of vinyl forming the top of the compartment and the second forming the bottom; and a second inflatable compartment disposed on the top of the first inflatable compartment and secured thereto at least alone a portion of the first inflatable compartment at a point spaced inwardly from the sides of said first inflatable compartment, said second compartment extending generally the length and width of the top of the first compartment, said second compartment being of a size, when inflated, sufficient to support a human body, and having an inflated height substantially less than the height of the first compartment; said second compartment being composed of at least two layers of vinyl distinct from the two layers of vinyl forming the first compartment; said second compartment being inflatable to give the top of the air mattress a soft, pillow-like appearance and feel, wherein said first compartment and said second compartment are secured together adjacent an open fluid communication channel, the fluid communication channel providing fluid communication between the first and second inflatable compartments to enable fluid in one of the first and second inflatable compartments to flow into the other of the first and second inflatable compartments, such that fluid pressure in the first and second compartments are equalized, wherein the first and second compartments are substantially free to move with respect to each other except at the periphery thereof. 2. An air mattress comprising: a first inflatable compartment having a top, a bottom, and substantially straight, vertically extending sides and having a height when inflated, said first compartment being composed of at least two layers of material, one layer of material forming the top of the first compartment and the second layer of material forming the bottom of the first compartment; a second inflatable compartment having a top and a bottom, the second compartment being composed of at least two layers of material, one layer of material forming the top of the second compartment, the second layer of material forming the bottom of the second compartment, the second compartment being positioned above the first compartment, said second compartment having an inflated height substantially less than the height of the first compartment; a perimeter seal connecting the top of the first compartment to the bottom of the second compartment, the perimeter seal being spaced inwardly from the sides of the first compartment; an open fluid communication channel providing fluid communication between the first compartment and the second compartment to enable fluid in one of the first and second inflatable compartments to flow into the other of the first and second compartments to equalize pressure in the first and second compartments; and a plurality of ribs extending between the top and bottom of one of the first and second compartments. 3. An air mattress comprising: a first inflatable compartment having substantially straight, vertically extending sides with a length, an inflated height and a width and defining a periphery; a second inflatable compartment extending generally the length and width of the periphery, the second inflatable compartment having a top and a bottom and an inflated height, the inflated height of the second compartment being substantially less than the height of the first compartment; a perimeter seal connecting said first inflatable compartment to said second inflatable compartment, wherein said perimeter seal is spaced inwardly from the periphery, a plurality of ribs extending between the top and bottom of the second compartment; an open fluid communication channel providing fluid communication between the first and second inflatable compartments to enable fluid in one of the first and second inflatable compartments to flow into the other of the first and second inflatable compartments to equalize pressure in the first and second compartments.
