Just don't wax your floors too well before buying into Jonas & Jonas furniture that leans against the wall and has just two legs. They say that "the scratch and shock-resistant body of this furniture is made of high pressure laminate and allows for any kind of strain" but I would be nervous about someone accidentally kicking a leg and having it collapse.
But I do like the minimalist look and it certainly doesn't take up much space.
