These chairs are made from old clothes, such as T shirts and jeans. I dont know if they are functional and if you can sit on them or not. Created by German designer Tobias Juretzek for Italian furniture brand Casamania they were presented in an installation at Milan Design week 2011.
Detail of the chair:
Imagine some future archeologist unraveling one of these chairs and finding odd things in the pockets like bus tickets and wondering "WHY?" Fun though!
