I don't agree that the futon, specifically, should be a tabletop item - because it's a bed. Beds go on the floor. However, I think that they should relax a lot of the tabletop/floor restrictions, because it's ridiculous what you can and can't put on things like the troupe stage. This could cover the futon, too. (Although given the way we float things, they probably don't want to relax the restrictions because of it. I still think they should.)
