The cast has been very uncomfortable in bed, so I would rest it on a soft small cushion. I knew that I needed some support for my wrist, so loosely wrapped it in an Ace bandage. I then laid it on the soft pillow, and had to adjust it a couple of times. I am pleased to say that it worked, as I was in the some position when I woke up.
I want it to continue to heal, but still need to protect it.
