Let's face it, slipcovers don't always fit, even though the dimensions seem to match your couch.  The duck fabric is thin, but we'll have to see how that washes and wears.  Color is as posted.    The  couch cover came very wrinkled, but the enormity of trying to iron that much fabric was just too much for me.  The cover is big and looks sloppy right now, but it's the best one I've found in many, many searches, so I'll keep it and hope it shrinks a bit in washing.    
It was easy to put on and I appreciated the instructions on where to put what (center back and center front tags}.
