Where can I find really cheap, but good looking, and in good condition, futon beds?

It doesn't really matter if its wood, or metal, but I really would prefer if there were no metal springs in the mattress, and it had solid, comfortable colors that can express some, like warm, but light brown colors, or a burgendy red, or maybe even a light sky blue, just some color that will feel homely, and comfortable.(and can fit in a 10' x9' room + more furniture)
