When you looked at the photo above, did you see a futon? Neither did we.
While it's closed, this Fu Chest Hide Away Bed looks like a chest. Opened, its solid wood platform offers support for a twin-sized futon mattress.
Although its style is not exactly our taste, it's also simple enough that it would be pretty inconspicuous in, say, a home office. And definitely more inconspicuous than your standard dorm room-style futon frame.
