Thanks for sharing. I also prefer really low pillows, so I've been switching between this thin pillow and no pillow. Will have to give the towels a try.
I'm thinking of also just doing a DIY latex mattress and swapping out the comfort layer if it starts to sag. I was thinking 6-8 inches of mattress, but how does it feel with only 4 inches?
