You see a lot of things on the internet, but perhaps this is the craziest looking sofa in the world. As readers, I will leave that up to you to decide. About this piece, it was designed as a public seating system and is called โMontebelloโ. The sofa was part of the permanent exhibition called โA Reviewโ featuring Austrian Architecture in the 20th and 21st centuries at the Architecture Center Vienna. โMontebelloโ can be purchased for โฌย 4,680 with colors upon request. You can see this and other great designs at the das mobel shop in Vienna, Austria.
