Abstract: A variable height, portable, inflatable foot and leg elevator comprises a plurality of adjacent prismatoid chambers, cooperating to form one inflatable prismatoid-shaped resilient body adapted to support the legs and feet of a user one way valve means providing for gas transfer between said plurality of prismatoid chambers, allowing the preplanned sequential inflation of selected prismatoid chambers such that the height of said variable height portable inflatable foot and leg elevator, can be increased upon the transfer of gas through one way valve means from one chamber, to an adjacent chamber, when the gas pressure in one chamber reaches a preplanned value, sufficient to cause the opening of the way valve means; inflating means attached to a first prismatoid chamber; deflating means permanently attached to said plurality of prismatoid chambers, permitting the deflation of said chambers, to thereby decrease the height of said foot and leg elevator; power means with control means for said inflating means, and
