Eight Sleep Pod 3 review: The high price of great sleep

I've always tried to get as much sleep as possible, but now that I have a one-year-old to look after, anything that can help maximize what little rest I do get is priceless. So when I heard that Eight Sleep was coming out with a new version of its smart mattress topper that offers better sleep tracking and temperature controls, I was curious to see how well it worked. And while the Pod 3 Cover is pricey, after a few months of testing, I never want to go back to a regular standalone mattress.
