The second tube has third and fourth axial ends and a second intermediate portion between the third and fourth axial ends. The first, second, third and fourth axial ends terminate in a plane. The first and second intermediate portions converge towards one another such that the first and second tubes form four legs supporting the membrane. The flexible membrane preferably includes first and second sleeves defining first and second lumens receiving the first and second inflatable tubes, respectively, and a plurality of wall panels coupled to and extending between the first and second sleeves.
