A foldable member including a first structural section foldable flat and biased to have an open configuration and a second structural section also foldable flat and biased to have an open configuration. The second section is longitudinally aligned with the first structural section when both structural sections are in the open configuration. A hinged connection between the first and second structural sections allows the first structural section to be folded against the second structural section when both structural sections are folded flat. |
