i have to sleep on my side, i use a fluffy one under my head, one between knees, and a giant one to drape the top arm over; and for some strange rib problem i have to sleep on the bad side or the ribs hurt.

when i can't lay on the bad side i make a wedge of pillows and sleep on my back, with a pillow under each arm. had to do this when i broke my shoulder.

i tried sleeping in a recliner. it does not work for me but it works for some.
