There are a number of tricks to adjusting the angled seats to a comfortable sleeping position. There are TWO "angled flat" positions (push the bed button a second time to toggle between the two positions). The alternate position adjusts the foot and back so they are not totally flat but many find it easier to sleep (and not many people know about this position). You can also play with the controls to find positions that are more comfortable by varying the angle of the foot, back, and overall seat angle. Full flat seats are definitely better for sleeping but there are ways to make the angled seats work. As others posted I find a few drinks also helps!
