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.
Three pillows. One thicker one leaned up against the headboard at a very slight angle, almost vertical. Then two thinner pillows, first one at what would be a 45 degree angle overlapping the thick pillow, then the final one overlapping that one.
Only way I have been able to find comfort in pillows in the last 5 years or so
