the only thing that was very helpful re. bedding (back in the day when I had severe pain, before it all went blissfully numb) was to put a single matress on top of my regular bed. That gave me troughs on each side, and I was able to use pillows to wedge my hands into positions where they weren't touching anything. Even brushing the sheet caused incredible pain, so sleeping with my hands up in the air was very helpful.
