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.
The best hugging pillow I ever had was a ridiculously large plushie, because the fill density was different. I haven’t figured out the head pillow yet, because sometimes as a side sleeper I try to hug those, too. I’ve mostly landed on ignoring the shaped memory foam pillows, because even if it says “for side sleepers” it usually feels better using as a traditional sleeper
I haven’t tried a plushy, but yeah, I also find sleeping accessories marketed towards side sleepers to generally be unsatisfactory.
