I feel that the vast majority of people should not need an elaborate setup to sleep well. If you need to spends hundreds or thousands of currency units on a setup beyond a basic bed, there is something wrong that could probably be fixed in a simpler way.

Consider Northern Europe. We live in Copenhagen and approximately zero percent of apartments have air conditioning. Personally, I sleep like crap for 3-4 weeks out of the summer and I'm totally going to try this next Spring.

Right. If people are overheating at night during relatively normal temperatures, it’s probably a medical/diet issue or something in the bed is making you over heat, such as stupid foam.

I think there's a simpler explanation for a lot of people: they like sleeping under a big fluffy comforter or a heavy quilt or so have you for weight/texture reasons, but don't want to cool down the entire house just to make that comfortable.

i've bought a moderately expensive, very comfy foam bed which is however much hotter than my previous absolutely cheap 20yr old spring mattress...

I'm apalled by the fact that in 20 years we have regressed rather than improved on the temperature aspect of mattresses

For myself I can sleep at any reasonable temperature. But between 60-65 F, I sleep extremely well. I do it with a relatively simple set up called an air conditioner, but I have fantasized about having a pillow that is always cool to the touch.
