I Slept Better Than Ever With Eight Sleep's Temperature-Regulating Pod 4
Briefly

The Eight Sleep Pod 4 is a temperature-regulating mattress cover that tracks your body as you snooze, with a hub that pumps cooled or warmed water into the cover.
Aside from the increased comfort, the best sleep trackers all told the same story: My wife and I slept longer and got more deep sleep and REM with the Eight Sleep Pod than without.
Sadly, better sleep does not come cheap. A Pod 4 Cover and Hub for a queen-size bed costs $2,599, but you must also take a year's subscription to Autopilot.
The Eight Sleep Pod 3 won me over with its ability to enhance sleep quality; its successor, Pod 4, offers improved comfort and functionality.
