Thanks! The description on the website made it sound like each section of the sofa reclined by itself. I knew it made the "flat" bed, but I thought there was also an option to use each half of the sofa in a "LaZy-Boy" fashion. I appreciate the clarification folks.
While I'm not sure that you'll find it to be comfortable, the seats actually have 3 positions. Fully up, halfway down, and flat. And the coach is made up of two sections, so each section moves indepenently of the other. The issue is that unlike an recliner, only the seat/bottom portion and the back portion move. The headrest remains fixed to the wall.
So if you recline the seats to the halfway position, you might be able to sleep partially sitting up. You'll have to use your pillow in the hole between the head rest and the top of the now partially reclined seat, but it could work. Ask your attendant to show you the halfway position, or try it yourself as it's really not all that hard. There is a metal bar across the front of the seat and to one side is a metal pedal. Step on the pedal to release the lock and push the seatback down while stepping on the pedal.
It will go to the halfway position and lock. If you want it fully down, then you pull the bar up and push the seatback all the way down. Reverse things to return the seat fully upright.
