Another fan here. Agree that the row doesn't make much difference. You are already clearly aware of the one very important point. That the REST of the experience is pure Economy! Having said that... with decent earplugs I find I sleep as well in the Skycouch as in Business. It is actually WIDER than J when set up... so those of us who happily sleep somewhat curled up (and are not too tall to start with) can be very comfortable IMO. As to cost, it always seems to come out about the same as Premium Economy... (SYD-AKL-LAX vv) and I can live with that for the chance to actually sleep. My only "complaint" is that the Skycouch rows seem to always board in the last row number group. The seats ARE well marked as "Skycouch" however and I have NOT experienced any poaching attempts. I
have regularly been asked questions about the product by genuinely curious Y passengers sitting nearby. Not really surprising.
