Front view of the air mattress air chamber. All of our air beds come with horizontally baffled vulcanized rubber air chambers. Designed for maximum airflow in all directions, the air chambers create the proper spinal alignment required for pain free sleep. This design also allows sleeping in the center of the dual models without the need of a foam wedge and with no sensation of rolling to either the middle or the edge. By sealing the web reinforced air hose with flexible rubber at the time of chamber manufacturing, the entire assembly becomes a single unit with no external connections eliminating the concern of air loss. These chambers are made from a durable 25 Mil rubber and are designed to provide support for years to come.
