We couldn't be happier with this futon frame.  It went together reasonably easily, and the drawers -- which I'd debated on -- roll smoothly and fit very nicely.  (The floor of the drawer will not bear a lot of weight, however.)

The futon does not lock in place well, though, so we had to ziptie it into a seated position to keep it from scraping against the stone wall behind it.

The mattress loses a star because it cannot be flipped.  The bonded leather surface -- which looks nice but feels a little plastic-y for actual leather --is only on one side and the edges.  The second side is an inexpensive fabric.  I was a bit disappointed by that, even though I had already decided to get a futon cover.
