What is Eight Sleep?
Eight Sleep is a 'sleep fitness' company founded by CEO Matteo Franceschetti, CTO Massimo Bassi, and VP of Brand & Marketing Alexandra Zatarain. After a successful crowdfunding campaign for its EIGHT: Sleep Tracker & Smart Bed Cover in 2015, Eight Sleep now sells three versions of its tech-loaded Pod Cover, one of which is rated our best smart bed of the year, along with other accessories to help hack your sleep.
What is the Eight Sleep Pod?
The Eight Sleep Pod is a cover you put on top of an existing mattress. It comes with a Hub, which serves as the 'brains' of the Pod and is roughly the size of a desktop PC. The Hub even has a quad-core CPU, along with a water reservoir for the Pod's active grid, which helps regulate temperature.
While the brand started with the Pod Pro, which became the Pod 2, there are now three versions available to buy: the Pod 3, Pod 4 and the Pod 4 Ultra. All include internal temperature controls plus sleep and health tracking. However, each model is an upgrade of the one before it in terms of sleep tracking accuracy and temperature regulation. The Pod 4 Ultra also comes with a bed base, offering even smarter features like adjustable positioning and snoring mitigation.
A subscription to Eight Sleep Autopilot is required to access the Pod's core features. Plans start at $17 per month and are billed annually. Up to two people can be on an Autopilot plan.
How do Eight Sleep Pod mattress covers work?
The Eight Sleep Pod smart mattress cover works with almost any mattress, providing it is between 10 and 16 inches tall. Although it'll likely work best with Eight Sleep's own five-layer memory foam mattress, which is specially designed to work with the Pod. You can access your sleep metrics with the Eight Sleep app (subscription required.)
Within the Pod cover are sensors to track key sleep and health metrics, along with tubes that pump water throughout the surface to heat or cool your bed. Eight Sleep therefore doesn't recommend using its Pod cover with an adjustable base since the tubes within are delicate and need to remain flat.
Eight Sleep Pod 4 vs Eight Sleep Pod 4 Ultra
The Pod 4 and Pod 4 Ultra share core features. But the latter boasts improved tech for the most accurate stats possible and adds an adjustable bed base for custom in-bed positioning, plus a couple of extra thousand dollars on the price tag. Here's a brief rundown of what each Eight Sleep smart mattress cover has to offer:
Are there extra fees with the Eight Sleep Pod?
To use the Eight Sleep Pod cover, you'll have to subscribe to Autopilot. This gives you access to your sleep and health insights, temperature controls, and thermal and vibrating alarms. Other perks include exclusive discounts on accessories and upgrades. Autopilot costs $17 per month (billed annually at $204). You can share the subscription with your sleeping partner so you both don't have to buy one.
An Enhanced Autopilot subscription costs $25 per month (billed annually at $300) and includes all of the above plus an extended 5-year warranty for your Pod. (The standard warranty is two years.)
What does the Eight Sleep app offer?
The Eight Sleep app provides sleep and health reports for up to two people. This includes your sleep stages, sleep time, sleep latency, heart rate, and heart rate variability (HRV). You can also use the app to set your ideal bedtime, deep sleep, and REM temperatures.
Do you need to buy the Eight Sleep mattress too?
You don't have to buy an Eight Sleep mattress to use a Pod cover, although the brand may argue that it yields the best results since they're made to complement one another. The Eight Sleep mattress is an 11" memory foam bed with five layers and a medium-firm feel. Adding a Pod cover turns it into the ultimate Eight Sleep smart bed.
However, Eight Sleep only has a 30-day return window for its Pod cover, and that appears to extend to its mattress, too. That's a very short amount of time compared to other mattress brands. The average sleep trial is 100 nights, while some brands offer up to a full year to try your new bed at home. Keep this in mind if you're considering an Eight Sleep mattress to go with your pod.
Who uses the Eight Sleep Pod?
Among Eight Sleep's biggest fans are 'high-performing individuals' such as Elon Musk, Mark Zuckerberg, Jessica Alba, Scarlett Johansson, Andrew Huberman, Tim Ferriss, Kevin Hart, and Joe Rogan.
Professional athletes also count on Eight Sleep for the restorative sleep they need to perform at a top level. These include NHL forward Sidney Crosby, Olympic swimmer Ryan Murphy, and Formula 1 driver George Russell.
Eight Sleep isn't exclusive to the rich and famous. Just browse through X (Twitter) and you'll find plenty of everyday users thanking their Eight Sleep mattress covers for improving their sleep quality and overall health.
Should you buy the Eight Sleep Pod?
Buy the Eight Sleep Pod if...
✅ You want detailed sleep stats, minus the wearables: Instead of wearing a watch or ring to bed, the Eight Sleep Pod mattress cover uses sensors to track key vitals and detect trends so you'll know where you need to improve. The Pod 4 Ultra has more discreet sensors than previous models for enhanced comfort.
✅ You and your partner steal the covers from each other: Sleep too hot or too cold? The Eight Sleep Pod mattress cover has built-in climate controls. Better yet, it's dual-sided so your partner can make their side as toasty or frigid as they'd like without interrupting your sleep.
✅ You otherwise like your mattress: The Eight Sleep Pod fits over your existing mattress to make it smarter. There's no need to buy a brand new mattress outright unless you absolutely want to. (Eight Sleep has a memory foam mattress you can purchase alongside the Pod mattress cover if you wish.)
Don't buy the Eight Sleep Pod if...
❌ You want an adjustable smart base: The tubes within the Eight Sleep Pod are delicate and must remain flat if you want them to work properly. On the other hand, you can add an optimized adjustable smart base to the Sleep Number i8 Smart Bed for zero gravity, custom firmness, and climate control.
❌ You can't justify paying that much for a cover: The least expensive Eight Sleep Pod cover goes for around $2,295 – and that's not accounting for the monthly subscription you'll have to pay to access the Pod's core features. Ultimately, it all adds up so unless price is no object when it comes to your sleep, maybe look into one of the best sleep apps you can get for free instead.
