Qatar Airways Haneda Flight Restart/How to Spend More Comfortably in Economy Class? Exploring JAPAN 

The answer is "Yes".
The Qsuite seat is gorgeous, luxurious, and comfortable. It is my best business class seat experience in the sky. I think it's probably better than some First Class seats.
Even economy class seats, if we chose emergency exit row or other row with extra leg room, it is far more conformable.
