I just flew through JED twice in the last fortnight TUN–JED–KUL and return on the same route, and I think ‘less cold’ might be an accurate way to characterise the Al Fursan lounge. I was wearing a t-shirt & cotton jumper, and the temperature was fine for sitting/eating, but I found it a little too chilly to sleep.

As for the seats, TUN–JED was on an older A330 without lie-flat seating—my seat was fine, but the gentleman next to me had a malfunctioning IFE in a full cabin—but the return A330 (HZ-AQI) flight JED–TUN, to my surprise, did have lie-flat seats, although there seemed to be several broken seats, mine (1L) among them, but, fortunately, the cabin was half-empty, so I could switch. My seats on the 787 to and from KUL were fine both ways.
