Also, add an "air cushion" that pushes the seat cushion forward to give some lumbar support as your bottom slides forward, to give a true angle from head to toe. I think this small change will make those Y seats that much better and minimize intrusion to the person behind you.

As for other improvements, let's be real, it's Y class, can't expect too much luxury.
