My bed is covered by them although when it comes to getting some shut eye they get thrown on the floor along with my teddy bears. Just a single down pillow does me. I'm allergic to feather pillows and the memory foam pillows give me neck pains.
My aunt had a water bed. Never liked the idea. I think it would make me seasick as well as paranoid about springing a leak. They're a huge liability for house insurance.
I have a special side sleeper pillow that costs a pretty Pennie, but it made a world of difference once I got it. A nurse at my doctor’s office recommended it and it was worth it.
