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’m a freefall sleeper so even no pillow works, otherwise a pilloe has to be flat and manoeuvred under my chest to stop my neck bending.
Freefall sleepers may have a slightly lower life expectancy but I’m like ‘meh’. Sleeping is nearly half my life.
I’ve never read that term before.
