Cheap Futon Mattress ebook for Windows. Excerpt: Futon beds are perfect for students living in dorm rooms, single people in cramped apartments and homes, and for kids - and they can also find a spot in the den as an extra bed for sleepovers and unexpected guests during the holidays. Futons are similar to sofa beds, but they are much more compact and easier to set up, and they are far less expensive. The futon itself serves as a sofa or couch when the bed is not in use.
