       BACKGROUND OF THE INVENTION 
       [0002]    Unfortunately, there are many tragedies around the world. The victims of these tragedies have undergone a life changing experience and face many hardships. These victims are typically without the basic needs such as food, potable water, and housing. The victims may have to spend countless days and nights in shelters and without housing. These victims need as quickly as can be provided some semblance of normalcy and comfort, during these trying times. The present invention may be given to these victims so that they can carry what personal belongings they have and to provide a comfortable place to rest by providing a substantial barrier or separation between the user and the ground or surface the present invention is placed. 
         [0003]    Luckily, there are brave and driven individuals that are willing to confront these tragedies and aid the individual victims that have been affected by these tragedies. Very often, these relief workers place their life and health on the line to aid others in a time of need and will find relief in the present invention. This invention may also be utilized by these workers who need a place to rest comfortably during the brief time period they may have to rest. The present invention may also be utilized by relief workers who need a place to rest comfortably. The present invention provides a bag that may carry relief supplies and gear, but also converts into an inflatable and/or expandable device, such as a mattress or the like, for allowing the relief worker a safe and comfortable place to rest. 
         [0004]    The present device may also serve a military function. The device may be utilized by soldiers that need a safe and comfortable place to rest, while also carrying supplies or military wares. 
         [0005]    The present device can also be used by others, such as a traveler, a child or the like that needs to have a readily available and comfortable place to rest.
