ABSTRACT:
A combined bed structure comprises a frame support and a mattress frame. The mattress frame is placed on the top portion of the frame support and comprises a frame casing, an inflatable mattress, and a cover layer. The frame casing is placed on the top portion of the frame support. The inflatable mattress is placed in the frame casing. The cover layer is placed on the top portion of the inflatable mattress. An inner frame slot with a slot opening and a slot chamber is positioned in the inner surface of the top portion of the frame casing. A hollow inflatable elastic tube is able to fully expand in the slot chamber and is connected along the periphery of the cover layer, so the cover layer is fixedly secured by inflating air into the hollow inflatable elastic tube and the cover layer is removable by deflating the elastomer.
