I have several health issues and I can't use a normal pillow. I used to have one that was very floppy, I'm not sure what it was stuffed with but the filling was loose (if you shook it at one end it would fall down and leave that end empty), but it definitely wasn't feather. It was very light so it wasn't memory foam chips.
I've tried loosely stuffing a pillowcase with memory foam chips, but I get ear pain from lying on it.
Please help! I'm using an ultra-soft normal pillow but I can't sleep properly with it.
