Abstract
A self-inflating air mattress comprising an airtight flexible jacket enclosing a core of a resilient, open cell, lightweight foam material, substantially the entire upper and lower portions of which are bonded to the envelope. The process of making this mattress comprises first laying down two sheets of an air impermeable plastic coated fabric, with the core positioned between the two sheets. Heated platens are applied to this layup, followed by applying a vacuum to the interior, cooling the assembly, and then moderately pressurizing the then bonded assembly.
