  • Air mattress with tensioned cover
    Patent number: 11470982
    Abstract: An air mattress assembly includes an air mattress and a cover system. The cover system is made of a fabric material. The air mattress, if fully inflated without the cover system in place, would be too large for the cover to fit over the fully inflated air mattress. With the cover system in place around the air mattress, the cover system will be under tension when the air mattress is inflated to operational pressures. In some embodiments the cover is bonded to the air mattress.
