Boeing launches business jet capable of world's longest flight

The interior of the jet on the article seems to imitate lounge.
But, what I need is comfortable beds rather than lounge.
Though there are sleeper trains around the world, I wonder why there isn't sleeper aircraft for the rich. First class seats are the nearest concept to it. But, they are not designed as complete beds.
I wish there would be beds on board.
