A support frame () having an outer frame () and an inner frame () which are connected on both a first side (FS) and a second side (SS) by flexible fixed length tension members (), as well as an adjustable length tension member (). The support frame has both a deployed and collapsible state, wherein the flexible fixed length tension members are under tension when deployed, and are slack when collapsed. This is achieved by reducing or increasing the length of the adjustable length tension member (). The outer frame and inner frame rotate relative to one another around an axis of rotation xformed by a first hinge member () and a second hinge member (). 110.
