High strength inflatable mattress

Abstract

A high strength inflatable mattress comprises: an upper surface, a lower surface, at least one side surface, a plurality of tightening sheets and at least one gas valve. The upper surface, the lower surface and the side surface have two PVC compound layers and a fiber layer, wherein the fiber layer is disposed between the two PVC compound layers. The side surface comprises PVC compounds, and the side surface is connected to the upper surface and the lower surface by a thermal melting method (such as thermal pressing, ultrasonic welding, or utilizing hot air, RF welding, hot wedge) to form a gas containment space surrounded by the upper surface, the lower surface and the side surface. Each tightening sheet is connected to the upper surface and the lower surface by the thermal melting method too.
