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 tried several pillows made of different materials different brands and everything else. But after all that I concluded the most comfortable I was when I used no pillows.
The big pillow is lying to you. You don’t need a pillow for comfortable sleep \s
