Eight Sleep Mattress Construction
The Eight Sleep Pod series mattresses uses a unique cooling technology that sets the ideal temperature for you. You can buy the Pod cooling technology to use with your existing mattress, or you can buy a Pod series mattress that includes the cooling system.
Cover
The Pod series mattress cover is made of a cool and breathable material. This durable layer lets air circulate and helps regulate mattress temperature.
Active Grid
Next is the Active Grid layer, which does the work of regulating the mattress temperature, from 55 to 110 degrees F. Warm or cool water flows through tiny channels as sensors track your sleep patterns. There are no wires, so you do not feel as though you are lying on a grid. A soft foam topper adds comfort.
Supportive Air Technology
Breathable, cooling foam layers relieve pressure and provide support. Thanks to millions of tiny cells, you get the comfort of memory foam without the heat retention.
FlexSpring Technology Core
This layer provides 4 inches of responsive comfort and support. Advanced foam conforms to your shape and springs back to support your spine.
Durable Premium Base
Finally, the 4-inch durable base provides sturdy support across the entire mattress. It also adds another layer of bounce for support and comfort.

Unique Cooling Technology
The Pod series mattress works through an app to set your mattress temperature. Temperature Autopilot will automatically set an optimal temperature at bedtime. If you share your bed, the dual-zone feature sets an individualized temperature for their side of the bed as well. How does this happen? Read the following sections to learn how the Eight Sleep Pod system works.
Active Grid
Part of the cooling technology is the Active Grid layer, which can also zip onto your existing mattress. Just below the Comfort Blend cover, the Active Grid maintains the mattress temperature as it receives a flow of warm or cool water from the Hub. It also has sensors that track your heart rate, sleep stages and other biometrics for optimal sleep settings.
The Hub
This is where the Pod technology happens. The compact Hub sits next to your bed, where it sends warm or cool water to the Active Grid. The Hub holds distilled water and hydrogen peroxide, and works through your WiFi. The water must be refilled approximately every 2 months.
Power Cable
Last but not least is the power cable. Just plug it in and you can have a sleep experience that’s just right for you.
Firmness That’s Just Right
Not too soft and not too firm, the Eight Sleep mattress has a medium feel. The durability, support and responsive foam layers make this mattress a comfortable choice for a wide range of sleep preferences. It’s a great firmness level for couples with differing sleep preferences.
Your Choice of Pod Mattress Sizes
Part of a comfortable night’s sleep is having the right mattress size. Eight Sleep’s Pod mattresses are available in 4 sizes:
- Full: 52.5″ x 74.5″ x 11″
- Queen: 58.5″ x 79.5″ x 11
- King: 74.5″ x 79.5″ x 11″
- Cali King: 70.5″ x 83.5″ x 11″
Eight Sleep Mattress Review: Pros and Any Limitations
Now that you know how Eight Sleep’s Pod series works, let’s see what it’s like to use. We have researched and reviewed the Eight Sleep mattress. In our opinion, it offers the following benefits as well as minor limitations.
Personalized Temperature Setting
The Eight Sleep Pod mattress keeps you cool when needed, or maybe a little warmer at times. Sensors in the Active Grid track your sleep patterns, heart rate and other biometrics to find a temperature that’s just right for you. If you share a bed, your partner will have their own personalized temperature setting. Now you can both be comfortable without getting up to adjust the thermostat.
Comfortable Active Grid
When you think of a grid, do images of uncomfortable wires come to mind? Not to worry with the Eight Sleep Active Grid. Instead of hard wires, it contains tiny water channels. Plus, it has a foam layer for even more comfort.You’ll just feel the comfortable temperature regulation, not the grid.

Pressure Relief
Besides an ideal temperature, pressure relief is essential for a restful, comfortable sleep. Eight Sleep’s Pod mattresses have a medium firmness that won’t leave gaps between your body and the mattress. It won’t let you sink too low, either. The breathable, responsive layers of foam support and contour to your body’s shape. This cradling effect keeps your back, shoulders and hips in alignment and relieves pressure.
Wake Up Gently
How refreshing it is to wake up without a jarring alarm! The GentleRise setting uses gentle, chest-level vibrations to wake you up in the morning. No more harsh alarms or disturbing your partner. Plus, the responsive foam layers reduce motion transfer, so your partner keeps sleeping when you get out of bed.
Compact Hub
The Pod series cooling system won’t take up a lot of space in your bedroom. The hub itself fits neatly next to your nightstand without bulky or unattractive equipment. All that cooling technology comes in a compact hub that just needs a water refill about every two months.
Ships in a Box
With the Eight Sleep Pod series, you don’t have to rearrange your day to schedule a mattress delivery. The Pod series mattress is shipped to your door in two boxes — one for the cooling system and one for the compressed mattress. If you’re out for the day, the boxes will be at your door when you get home.
After you unbox your mattress, however, you may want to wait 24 hours for it to fully expand. You may also notice an unpleasant odor or “off-gassing” when it comes out of the box. The odor should dissipate in a few hours.
100-Night Trial
When you’re shopping for a top-rated cooling mattress, it helps to know that a company has confidence in their product. You’ll love Eight Sleep’s 100-night risk-free trial. You can try the Pod series mattress at home for more than 3 months. If you are not satisfied with the mattress, Eight Sleep will arrange a free pickup and refund.
Warranty
Eight Sleep backs their Pod series mattresses with a 10-year limited warranty and the technology bundle with a 2-year limited warranty. The warranties cover manufacturer defects not caused by improper use or normal wear and tear. The company will repair or replace a mattress or technology bundle that has covered defects.
Warranty terms can change or be updated at any time. It’s a good idea to check the latest warranty terms before you buy.
Eight Sleep Mattress Review: Concluding Thoughts
The Eight Sleep Pod series is a unique and innovative cooling system. You can buy the cooling technology alone or with a Pod series mattress. Either way, you get a personalized temperature setting that lets you sleep comfortably. For couples, the system has individual settings for each side of the bed.
The Pod cooling system works through a series of tiny channels that send warm or cool water to an Active Grid in the mattress. The water flows from a compact Hub that fits next to your nightstand. The system works through your WiFi and a smartphone or tablet app to customize temperature settings. Sensors in the Active Grid track your biometrics to automatically set the optimal bedtime temperature.
There’s even a silent, GentleRise setting that wakes you up with quiet vibrations. Your partner can sleep undisturbed and you can wake up gently.
The mattress itself contains foam layers that provide support and comfort you’d expect from a top-rated cooling mattress. Breathable, responsive foam contours to your body’s shape as it keeps your spine properly aligned. You’ll feel like you’re sleeping on a cloud, thanks to the pressure relief.
One minor inconvenience is the wait time while your Eight Sleep mattress decompresses. After you unpack your mattress from the shipping box, it can take 24 hours for it to fully expand. You may need to air it out for a few hours as well, to get rid of that “new mattress smell.”
You can have peace of mind about your Eight Sleep purchase. The 100-night risk-free trial lets you try the mattress at home for more than three months. The Pod series mattress comes with a 10-year limited warranty, and the technology bundle comes with a 2-year limited warranty.
After our research and review, it is our opinion that the Eight Sleep mattress is a quality product of value.
