I feel like I used to have a satisfactory layout for years but haven’t since found a consistently comfortable arrangement. I like to have a fairly thick pillow or two under my head to accommodate my bad shoulder, a pillow between my thighs to avoid chafed skin, and a pillow for hugging - also mostly for my shoulder.
The head ones tend to get distorted really quickly and it’s really difficult to find a good hugging pillow.
I have two pillows on top of each other, one stuffed with raw wool, and one made from layers of wool and cotton batting. Which one is on top depends on the season.
