I might be the odd one who finds the new regional J seats not that comfortable. I'm 5'7 so I consider myself average height. When reclining the seat back a bit, it seems like the whole seat first rotates backwards, effectively raising the front part of the seat and I'm left with my feet just barely touching the floor if you know what I mean. I find it quite uncomfortable especially when dining. Of course the seat is comfortable if I need to recline more and deploy the foot rest for a nap, but usually don't need that for a 3 hour flight.
