A structure which is transformable by inflation from a collapsed condition for storage to an erect condition for use has an inflatable tubular framework and at least one flexible web attached to and extending between two or more regions of the framework. The inflatable framework is formed by at least one inner inflatable tubular element (A, B) of flexible, elastic, air-impermeable material and having an inflation valve (13,15) accommodated within an outer sleeve arrangement of a material which is flexible but substantially non-elastic and restrained therein upon inflation. The outer sleeve arrangement is configured to include at least one branch point and/or at least one abrupt bend and the configuration of the inner tubular element or elements (A, B) corresponds to that (branch points (a, b) and abrupt bends (z)) so that the inner tube or tubes will substantially fill the outer sleeve arrangement upon inflation. Each inner tube (A, B) is formed by cutting and bonding of the air-impermeable material to provide a continuous inflatable compartment of relevant configuration and is inserted through an opening in the outer sleeve arrangement and fed through so as to fill it when later inflated in use.

1. A method of producing a structure transformable by inflation from a collapsed condition for storage to an erect condition for use, the structure comprising an inflatable tubular framework that, when inflated, supports the structure in an erect condition, and at least one flexible web attached to and extending between two or more regions of said inflatable framework, the method comprising: fabricating an outer sleeve arrangement of flexible but substantially non-elastic material by cutting and stitching said material to a sleeve configuration that includes at least one bifurcation;separately fabricating an inner inflatable tubular element of flexible, elastic, air-impermeable material by cutting and bonding the air-impermeable material to provide a continuous inflatable compartment having a configuration including at least one bifurcation, matching the configuration of the outer sleeve arrangement, and having an inflation valve; andinserting the inner tubular element into the outer sleeve arrangement and feeding it through the outer sleeve arrangement so that, upon inflation, the inner tubular element substantially fills the outer sleeve arrangement. 2. The method according to claim 1, wherein the inner tubular element has a maximum inflated diameter greater than the diameter of the outer sleeve arrangement. 3. A method of producing a structure transformable by inflation from a collapsed condition for storage to an erect condition for use, the structure comprising an inflatable tubular framework that, when inflated, supports the structure in an erect condition, and at least one flexible web attached to and extending between two or more regions of said inflatable framework, the method comprising: fabricating an outer sleeve arrangement of flexible but substantially non-elastic material by cutting and stitching said material to a sleeve configuration that includes at least one bifurcation;separately fabricating at least two inner inflatable tubular elements of flexible, elastic, air-impermeable material by cutting and bonding the air-impermeable material to provide two separate continuous inflatable compartments, each having a configuration including at least one bifurcation, matching the configuration the outer sleeve arrangement, and each having at least two closed ends and an inflation valve; andinserting the inner tubular elements into respective parts of the outer sleeve arrangement and feeding them through the outer sleeve arrangement so that, upon inflation, the at least two closed ends of one of the inner tubular elements confront locations on the same inner tubular element or the other inner tubular element thereby to substantially fill the outer sleeve arrangement. 4. The method according to claim 3 wherein the outer sleeve arrangement is fabricated to include closed loop framework regions and the inner tubular elements are inserted into the closed loop framework regions so that upon inflation the inner tubular elements similarly form a closed, but discontinuous, inflated region supporting a part of the structure. 5. The method according to claim 3, wherein at least one of the inner tubular elements has a maximum inflated diameter greater than the diameter of the outer sleeve arrangement,
