 a wedge shaped envelope comprising a top surface, a bottom surface, a back surface, a first side surface and a second side surface, said top surface having a forward portion,    one or more internal support strings, each of said strings having a first end and a second end, said first end of each said internal support strings attached to said first side surface and said second end of each said internal support strings attached to said second side surface; and    a closable valve located on any of said top surface, bottom surface, back surface, first side surface or second side surface.    
     
     
         2 . The inflatable bed support of    claim 1    further comprising: 
 one or more additional internal support strings, each of said additional internal support strings having a first and second end, said first end of each said additional internal support strings attached to said back surface and said second end of each said additional internal support strings attached to or near said forward portion of said top surface.  
 
     
     
         3 . The inflatable bed support of    claim 1    further comprising:
