I’ve Had It With These “Cooling” Sheets & Fabrics That Don’t Make a Difference.
I mean, have you guys actually slept on linen? It’s not cooling, it’s just scratchy. Percale is probably the best bedding option I’ve used—but even then, the “cooling” benefits are so marginal. I’m tired of seeing these marketing claims for products that, at best, have passive cooling attributes.
But turns out there’s a product out there that’s anything but passive. I’m talking about a real-time, AI-powered, active cooling sleep system that can go 20° lower than the ambient temperature in the room: Eight Sleep’s Pod 4 Mattress Cover. This thing is not merely “moisture-wicking.” It’s an award-winning, pro-athlete-obsessed smart bed that even impressed Elon Musk.
To be fair, you can get a new set of nice sheets for $200. The Eight Sleep Pod 4 costs $2,499 for a Queen size. But after hearing too many people tell me Eight Sleep changed their lives, I said f*** it and splurged. And let me tell you honestly: this is the best purchase I’ve made in my adult life.
There’s a difference between passive and active cooling for a reason. Eight Sleep is clinically proven to improve your sleep by 32%… but that’s just the tip of the iceberg.
Here’s Why Everyone Is Talking About Eight Sleep
Eight Sleep has been on my radar for a while now… mostly because it’s all over Twitter (are we calling it X, yet?). Since 2014, Eight Sleep has been making enormous waves among the world’s top-performing people. Big names like Elon Musk and Mark Zuckerberg, Olympians, F1 drivers, and more have publicly shared their love for this sleep tech—even the most famous podcaster in the world called it a “f***ing game changer.”
And the proof is in the pudding. This study shows Eight Sleep improves sleep quality by 32% and increases deep sleep by 34%. Essentially, Eight Sleep makes your eight hours a night ⅓ more effective. And take it from me. You really feel the difference.
Eight Sleep won a Men’s Health Sleep Award and a TIME Best Invention for their previous generations, but they recently rolled out their latest, the Pod 4 (what I got) and the Pod 4 Ultra. On top of double the cooling power, the new-gen Pod also offers 40% quieter performance, clinical-grade sleep tracking, and adjustable sleeping positions.
They made the world’s smartest bed and just keep making it smarter.
The Dynamic-Cooling Tech Designed by Experts + Scientists
Essentially, the Pod 4 is a mattress cover that seamlessly fits over any bed and attaches to a WiFi-controlled, water-filled Hub. It uses biometric sensors and an AI-powered feature called Autopilot to cool or warm the bed from 55°F to 110°F based on what’s optimal for your body in real-time.
Sleeping cool isn’t just about comfort, as it turns out. Sleeping cooler has been shown to increase your sleep quality—which means more shut-eye, more energy during the day, and less tossing & turning in red-hot rage sweatfests at 3am. Great sleep is a human’s #1 superpower, and Eight Sleep has given it a power-up.
So no, this is not your everyday “cooling” sleep product. This is like an Ironman suit for your bed. Autopilot even gets smarter over time, iterating off your health and sleep metrics to find the optimal sleep environment.
My Experience With This Holy Grail of Sleep
The first thing I noticed when I started using my Pod 4 is that I slept through the night in the middle of July for the first time in probably 5 years. The second thing I noticed is that I no longer had to blast the hell out of the AC (which means the electric company didn’t have to blast my utility bill).
Before I got this thing, I thought the tech bros tweeting about how Eight Sleep “changed their lives” was just bro-speak for “I like this.” But now I understand. It’s like each night I’m getting the best sleep of my life. I never wake up in the middle of the night and never wake up with brain fog in the morning. And I never sweat. Which means my wife isn’t yelling at me for having to wash the sheets twice a week.
Here are some other features that I’ve really come to love:
- Dual temperature zones: That’s right. While I freeze-blast my side of the bed, my wife can actually sleep with a normal human temperature. And never the ‘twain shall meet. Everyone’s happy.
- Real-time results: It’s kind of genius to design a way to track your sleep progress into a product that’s supposed to improve your sleep, because now Eight Sleep has receipts. I know my feeling better with Eight Sleep is not just a placebo effect because I’m looking at biometric proof of increases in my REM & deep sleep.
- Gentle rise alarm: This is one of those shiny bells and whistles that I now cannot live without. When it’s time to get up, the Pod 4 will gently vibrate and warm up to rock me to consciousness. I never get tired of it. (I rarely get tired at all these days.)
In a World Where Everyone’s Obsessed With Cool Sleep, Eight Sleep Actually Gives It to You
I can’t stress enough how amazing it is to sleep at the perfect temperature all year round. Is the Pod 4 cheap? No. But, to me at least, blissful sleep like this is always worth it.
It’s worth mentioning the Pod 4 Ultra, their top-of-the-line product, even comes with an adjustable base for custom body positioning and the ability to detect and stop snoring. If you’re looking for the cream of the crop, start there. Eight Sleep offers both the Pod 4 and Pod 4 Ultra for $0 down followed by interest-free installments, with free shipping and a 30-night, risk-free trial.
