         6 . A cushion according to  claim 2 ,  3 , or  4 , and including a fill tube attached to the bladder and extending through said second cushion element for permitting the volume of fluid within the bladder to be selectively increased or decreased.  
     
     
         7 . A cushion according to  claim 2 ,  3 , or  4 , and including a fill tube attached to said bladder and extending through said first cushion element for permitting the volume of fluid in the bladder to be selectively increased or decreased.  
     
     
         8 . A cushion according to  claim 2 ,  3 , or  4 , wherein said bladder includes a screw cap for being selectively moved between a closed position for maintaining the volume of fluid within the interior of the bladder, and an open position for permitting the volume of fluid to be selectively increased or decreased.  
     
     
         9 . A cushion according to  claim 2 ,  3 , or  4 , wherein said first and second cushion elements are adhered together, thereby forming a unitary structure.  
     
     
         10 . A cushion according to  claim 2 ,  3 , or  4 , wherein said first and second cushion elements each comprise a foam material.  
     
     
         11 . A cushion according to  claim 2 ,  3 , or  4 , wherein said fluid comprises a liquid.  
     
     
         12 . A cushion for use in combination with a seating product, said cushion positioned on said seating product for supporting a user thereon and comprising first and second cushion elements joined in registration and collectively defining a void therein for receiving a flexible, fluid-impervious bladder adapted for receiving a preselected volume of fluid for providing adjustable support to the user.
