LucidIf you want something a little more substantial than a mat on the floor or a polyester-stuffed futon cushion, Lucid's 4-inch Mattress-Sofa is a sweet spot.High-density foam, a removable and machine-washable zipper cover, and carrying handles make the Lucid Comfort Couch a practical if somewhat clunky-looking step between a bed and a couch.
Let's face it: Futon mattresses tend not to be the most comfortable places to crash. They're not uniformly firm or plush, and they can bunch up over time. This high-density foam makes for a consistently firm sofa (and bed) that won't start to sag or soften, and again, unlike many futon mattresses, it's washable.
The Lucid Mattress-Sofa also comes in various sizes, from a basic twin to a queen, as well as a double-wide king-size (which is the best deal, if you have the room for it).
What's more is that while a lot of futon and sofa brands will only offer a year warranty, Lucid offers a three-year one protecting you from manufacturer defects. You can also purchase an extended 10-year warranty for about $30.
If you're in need of a couch and a second bed, but don't have a lot of space, or plan to car-camp or move frequently and don't want the burden of heavy, full-framed furniture, Lucid's Mattress-Sofa is a functional, affordable, and most importantly comfortable addition to your dorm room, studio, living room, or camper
Another option, and arguably one with a slightly more appealing shape, is the Couchbed. We've reviewed it, and we recommend it, but it sits a little low for some people (and rooms), and the creases it leaves when unfolded into a bed can be uncomfortable.
Pros: Firm, high-density memory foam, various sizes available, easy to move, lightweight, washable cover, more comfortable than the average futon
Cons: Maybe not the fanciest looking thing, but you can dress it up
