In the quest to optimize my sleep I have found over the last days that I relaxed a lot more as usual. I sleep on the side but I put cushion between my back and the wall so that part of my weight rests on the back and part rests on the mattress of the bed.
Are there any real reasons why standard beds are flat? Or is it just a cultural custom like our standard toilet design that exists for stupid reasons?
not that I know of. Various suggestions of sleeping with a body pillow exist. Hammocks exist. Plenty of people take naps on couches or in reclining chairs.
I wonder if it has anything to do with ease of manufacture.
I am sure you have read this: www.lesswrong.com/r/discussion/lw/mvf/
(relevant side note) Traditional Japanese beds are harder and thinner than western beds.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
