/jp/ - Otaku Culture

So my family is moving soon, and I'm going to be sort of shafted when it comes to living space. Due to this, I've been considering buying a futon rather than moving my already existing bed, both to save space, and because I just like the idea of having one to be honest.
Problem is, I sleep on my stomach, which is rather rare, as most people sleep on their back or side. So I need to find a nice, thick futon that will support me so as to keep my back in good shape.
Do any of you good fellows on /jp/ have a futon? What kind do you own? Where did you get it?

Feel free to turn this thread into Japanese Furniture general as well.
