tapisofa.

Olivier Gregoire created this amazing semi-formless piece of furniture called Tapisofa that can be a couch, chair, lounge or whatever else you can think up...as long as it's in a corner. It's actually "a carpet with an unpredictable natural shape" and it "can be modulated thanks to it's [sic] soft frame." Brilliant. Unfortunately it's only a concept at this stage.
