(also breaking rules to concur)

EightSleep mattress cover is a GAME-CHANGER. Precise control over preferred temp, and detailed/accurate logging of sleep metrics == way better sleep, and knowledge of its relative quality (metrics for which let me measure the impact of different variables).

Never heard of them, temperature control sounds amazing. How is this product from a privacy perspective? Is the data kept local or is it some cloud service that tracks all metrics?

Not sure about the privacy but afaik you can’t use the thing without the app and being connected to the internet. That was a dealbreaker for me

Is it _that_ much better than a wifi-controlled two-zone electric blanket?

I've never tried a cooling electric blanket. My wife has struggled w insomnia for a long time, and the eightsleep tracking was almost as much a draw as the cooling.

This does cooling too? OK, I didn't realise that. I can see how that might be useful

How do they work thermodynamically? It should make the room hotter, but I guess you don’t notice because the surface you are touching gets colder? Is it a closed loop heat exchanger or is it evaporative?
