A little 'Exta' to sit on from aluminium extrusions?

As seen on Designboom website quite an interesting contemporary chair design made from aluminium extrusion.

'The Exta chair by Tarazi studio is constructed from a single aluminum profile. It is produced through an extrusion process, which results in a transformable-width chair that can also become an endless bench when multiple pieces are put together.

The structure transforms its purpose according to its position - as a back-rest, seat or foot rest. each component is realized by one of these functions(dent, arch and notch). the way the chair is made allows it to fit to any body size.

The chair was first constructed as a prototype in 2007, and is now being produced in a new 2009 edition.'

Quite an interesting and adaptable design using the same design principles and adaptability used in my own Industryindesign collection.
