Don't forget that the roomette seats can recline to a decent angle.
As the OP indicated 'we', I'll presume they're traveling with someone. It's altogether possible that in these days of too-short LD consists, both may be in the same seat, limiting 'horizontal space' for leaning/slouching/getting comfortable.
My biggest complaint with roomette seating is the uncomfortable 'armrest' on the window side. I've solved this problem with inflatable pillows that come with a separate travel blanket inside. I can inflate the pillow to its maximum size and then 'ball' the blanket and use them both for an armrest or back support. As the seat is quite wide, I usually don't use the 'armrest' at all.
If both seats in a roomette are reclined, if traveling with someone, it becomes a tangle of legs and feet. If traveling alone as I do, I usually recline to the maximum, slouch with a pillow under my back, and my feet are under the seat ahead of me. I sometimes put my feet with shoes off on the opposite cushion as well. It's rare I have the seat at the fully up position.
