Here's my thoughts on the 8 Sleep after three weeks.
- This thing is very, very well designed. As a rule, I don't mix electric and water but they've done it and it works very, very well. Heats up and cools down fast.
- It has certainly improved our sleep. Surprisingly enough, my wife has gotten more benefit out of it than I have. She's been sleeping like a baby since getting her settings dialed in. My sleep has improved since we got it but nothing crazy -- likely because I do a ton of family law and during this hot ass summer, my work life is just a constant pressure cooker. I wish we had gotten it when things were calmer so I could get a fairer test.
- It takes some getting used to. Even if you think you sleep hot or cold, I'd encourage anyone to start with it at zero for a few nights before adjusting too much. At zero, it wicks away heat and sweat so it provides a surprisingly large benefit. We always felt slightly clammy for the first two weeks or so because we didn't really know how to process the feeling of body temperature and sweat being wicked away by a heat sink.
- The AI is blah. I despise AI, so I'm a harsh critic but it doesn't really do much after you get your temperatures dialed in. If that's big to you, do not take my word for it since I was frankly looking for a reason to not use the AI unless it was just a dramatic improvement and it certainly is not that.
- The best thing for couples may be that it creates conversations about how each other is sleeping and let's you be creative about how to accommodate your partner's habits. For instance, we learned that I tend to snore early in the night and my wife does really late. That appears to because she does great for REM sleep and bad for SMS sleep and I'm the opposite. We've been able to do little things that have helped us both improve.
I certainly would not say it is an absolute gamechanger or a must have. However, I'm keeping it and we just had an offer accepted on a house so an extra $3k in my pocket would be nice right about now. It really comes down to how much that much cash means to you.
I would not even consider buying one unless I had everything else squared away, including my finances. Anyone who finances one of these probably donated to La Familia, too.
