I got my couch and even though it says reversible, I don't think it is. Looks like the cushion that connects the sofa and chaise does not tailor for a right side chaise. 
The first picture is trying to put the flat side on the back which definitely does not fit. The second picture is with the flat side inside.  I'm wondering if this couch is really reversible? It does work for a left side chaise, but does not work for a right side chaise the way I've received.
