ABSTRACT:
A tufted air mattress including a first printed sheet and a second sheet. The first printed sheet is printed over a selected area with an ink containing a fluoropolymer. The portion of the printed sheet with the ink defines a coated area. The first printed sheet attached to the second sheet where the printed sheet is not coated with the ink. The coated area of the printed sheet inhibits heat welding of the first sheet to the second sheet. The coated area also lubricates the first and second sheets to aid in inflating the air mattress without flaking and contaminating the air inflating the air mattress. In one embodiment of such a mattress, three sheets define two air volumes that are alternatingly inflated and deflated through an alternating air supply valve.
