Claim 0:
1. An improved method of inflating a dual air chamber device, said method including the following steps:
A) Providing a dual air chamber device, said device comprising:
1) an outer chamber configured for selectively retaining a volume of air, said outer chamber itself comprising:
a) an outer chamber air valve configured to be either open or closed so as to allow or prevent airflow therethrough, respectively;
b) an upper wall; and
c) a lower wall,

said upper and lower walls and said air valve configured to combine to at least partially provide a closed chamber configured to retain a volume of air when said outer chamber air valve is closed,
2) an inner chamber configured for selectively retaining a volume of air, said inner chamber itself comprising:
a) an inner chamber air valve configured to be either open or closed so as to allow or prevent airflow therethrough, respectively;
b) a plurality of vertical elongate spaced apart inflatable posts, each of said inflatable posts having a pair of opposing ends being a top end and a bottom end, each of said pairs of opposing ends configured to increase in distance from a shorter distance to a longer distance when air is introduced into their particular post; and
c) an interconnected grid of inflatable tubing providing for air communication between said plurality of inflatable posts and said inner chamber air valve, wherein said inflatable tubing and said inflatable posts have substantially the same diameter upon inflation,

said plurality of elongate spaced apart inflatable posts, said grid of inflatable tubing, and said air valve configured to combine to at least partially provide a closed chamber configured to retain a volume of air when said inner chamber air valve is closed, said upper wall of outer chamber said having said top ends of said inflatable posts in contact therewith and said lower wall of outer chamber said having said bottom ends of said inflatable posts in contact therewith;

B) providing said outer chamber air valve of said outer chamber in an open configuration;
C) while said outer chamber air 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 air valve while said inner chamber air 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 tends to be drawn into the open outer chamber air valve in the outer chamber due to the presence of a relative vacuum within said inner chamber, said inner and outer chamber being interconnected such that introduction of air under pressure into said inner chamber causes said inflatable posts to extend in length, such that said top ends of said vertical posts push upwardly against said upper wall, and such that said bottom ends of said vertical posts push downwardly against said lower wall, causing said upper wall to move upwardly away from said lower wall, such that a vacuum is provided within said outer chamber, said vacuum being sufficient to cause air to be drawn into said outer chamber air valve when in its open position;

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