First, I will say this couch is beautiful, but if you're buying it for a sleeper, DON'T.  You may as well buy a regular couch because that's all the room you'll have with this.  It does transform to a flat surface, one that is completely unstable.  We'll never be able to use it as intended, but I don't want to pay $130 to return it.  We'd like it well enough to keep it as a small sofa for our grandkids.
