Metal is more flexible than many people give it credit for, hence the long series of (eventually successful) attempts by Moran Barmaper to inflate this remarkably malleable material.

For now, desks and chairs are the signs of success – wooden (or metal) frameworks supporting a kind of metallic balloon used as a cushion or to create a more robust edge for surfaces made from thin slices of metal.

As interesting as the metal-as-surface concept is, the real trick is how it all hangs together: no screws or glue are required, as the very process of pushing air into the metal locks it into the surrounding joints to create a rigid structure.
