Claim 5:
6. An improved method of inflating a dual air chamber device, said method including the following steps:
A) Providing a multi compartmental supporting device having at least two chambers, an inner chamber and an outer chamber,
said outer chamber including an upper and a lower wall, and also including a selectively closable outer chamber valve for allowing air in and out of said outer chamber,
said inner chamber itself comprised of a plurality of spaced apart inflatable posts, each of which has its top end in contact with said upper wall of the outer chamber, and each of which has its bottom end in contact with said lower wall of the outer chamber,
said inner chamber also including a selectively closable inner chamber valve for allowing air in and out of said inner chamber;
said inner chamber valve independently operable relative to said outer chamber valve, such that said outer chamber valve can be left open while said inner chamber valve is open and said inner chamber is inflated,

B) providing said selectively closable outer chamber valve of said outer chamber in an open configuration;
C) while said outer chamber valve of said outer chamber is in said open configuration as a result of Step B, inflating said inner chamber by introducing air into said inner chamber valve while said inner chamber valve is in an open position,
such that as said inner chamber is inflated, its inflatable posts combine to push apart said upper and lower walls of said outer chamber, and such that air is drawn into the open outer chamber valve in the outer chamber due to the presence of a relative vacuum within said inner chamber,

D) after said air has been drawn into said outer chamber while said outer chamber valve of said outer chamber is in said open configuration, closing said inner chamber valve to a closed configuration; and
E) while said inner chamber valve of said inner chamber is in said closed configuration as a result of Step D, closing said outer chamber valve to retain said air drawn into said outer chamber due to said vacuum.
