       10 . The inflatable support system of  claim 8 , wherein at least two of said coil sizes at least partially define said first zone.  
   
   
       11 . The inflatable support system of  claim 9 , wherein at least two of said coil sizes at least partially define said second zone.  
   
   
       12 . The inflatable support system of  claim 10 , wherein at least two of said coil sizes at least partially define said third zone.  
   
   
       13 . The inflatable support system of  claim 1 , wherein said electrically powered pump is non-removably mounted to said inflatable chamber.  
   
   
       14 . An inflatable support system comprising: 
 an inflatable chamber comprised of an external surface and at least a top layer and a bottom layer;    an electrically powered pump configured to inflate said inflatable chamber;    a first type of internal structure defined within said inflatable chamber, said first type of internal structure comprised of at least one substantially flat layer of material formed in a loop, said loop having open ends; and a second type of internal structure defined within said inflatable chamber, said second type of internal structure comprised of at least one substantially flat layer of material formed in a loop, said loop having open ends.    
   
   
       15 . The inflatable support system of  claim 14 , wherein at least a portion of said first internal structure is attached to said top layer of said inflatable chamber, and at least a portion of said first internal structure is attached to said bottom layer of said inflatable chamber.  
   
   
       16 . The inflatable support system of  claim 15 , wherein at least a portion of said second internal structure is attached to said top layer of said inflatable chamber, and at least a portion of said second internal structure is attached to said bottom layer of said inflatable chamber.  
   
   
       17 . The inflatable support system of  claim 16 , wherein said first type of internal structure is attached by a first weld size to said top layer of said inflatable chamber; and 
 said second type of internal structure is attached by a second weld size to said top layer of said inflatable chamber.    
   
   
       18 . The inflatable support system of  claim 17 , wherein said first type of internal structure is attached by a first weld size to said bottom layer of said inflatable chamber; and 
 said second type of internal structure is attached by a second weld size to said bottom layer of said inflatable chamber.    
   
   
       19 . The inflatable support system of  claim 16 , wherein said first type of internal structure is attached to said top layer of said inflatable chamber at a first weld forming a first shape on said external surface of said inflatable chamber; and 
 said second type of internal structure is attached to said top layer of said inflatable chamber at a second weld forming a second shape on said external surface of said inflatable chamber.    
   
   
       20 . The inflatable support system of  claim 19 , wherein said first type of internal structure is attached to said bottom layer of said inflatable chamber at a first weld forming a first shape on said external surface of said inflatable chamber; and 
 said second type of internal structure is attached to said bottom layer of said inflatable chamber at a second weld forming a second shape on said external surface of said inflatable chamber.    
   
   
       21 . An inflatable support system comprising: 
 an inflatable chamber having an outer surface;    and electrically powered pump configured to inflate said inflatable chamber;    said inflatable chamber having at least one zone of firmness comprised of a first pattern of coils and    said inflatable chamber having at least one zone of firmness comprised of a second pattern of coils.
