There is a “smart” everything, nowadays.
So it’s no surprise that we finally have a smart mattress.
The Smart Bed by Eight Sleep is fairly ordinary underneath the cover – 4 layers of foam work together to provide pressure relief, contouring, and support.
The cover, however, is a totally different story. It is decked out with advanced sensors that provide you with an unusually informative and high tech sleeping experience.
The best feature of this smart mattress is the warming function, which you can use to raise the temperature on either side of the bed. I'm sure a lot of couples will appreciate this one.
Sensors in the cover can also track your heartbeat, movements, respiratory rate, REM sleep and sleep time. Through its companion app, the Smart Bed tells you how well you are sleeping and helps you improve your sleep quality.
You can even connect your mattress to Alexa directly or to Google Home and other services and devices through IFTTT.
So if you’ve been waiting for a smart bed for you & your partner – this is your chance.
To be honest: the Smart Bed was lot less expensive than I expected.

About Eight Sleep
Eight Sleep launched in 2014 with the goal of integrating technology into everyday sleep products.
The company actually started in 2014 as an Indiegogo campaign to market and sell their sleep tracker, the only product they offered at that time.
The reason they created their sleep tracker technology is because their CEO/founder was having issues with his restless leg syndrome and he wanted to know why he was having trouble sleeping. After looking at the data he realized that he slept poorly if he exercised too close to bedtime.
In 2015, EightSleep launched their first smart mattress online, then launched the Smart Bed in December 2016 based on tons of research.
Using a data-driven approach, they have now studied over 200 billion data points and tracked over 10 million hours of sleep to make the most comfortable mattresses and best sleep-tracking tech.
Today, the company sells two products today:
- Smart Bed (Queen = $2,495): 10″ thick, heats only, Smart Cover
- The Pod (Queen = $2,995): 11″ thick, dual-zone climate control, heats and cools, Smart Cover
Note: this review focuses on the Smart Bed. See my separate review of The Pod here.
Eight Sleep designs and assembles their mattresses in the United States. This provides quality local jobs and ensures the best quality products.
The foams used in the mattresses are CertiPUR-US certified. They don’t contain any chemicals that could harm users or the environment.
Also, Eight Sleep offers a 10% discount to students, active military personnel and dependents as well as veterans.
Eight Sleep mattresses are available in a number of retail outlets including Amazon.
But it’s best to buy them through the official website. You’ll be assured of a genuine product, and you’ll enjoy a 100-night trial period. Other sellers sometimes have different return policies.
On EightSleep's main website, go to the main product page for the Smart Bed and select your mattress size. They offer Full, Queen, King and Cal King sizes. No Twin sizes are available yet.
Finally, you can select a firmness or design your own custom split mattress configuration using Eight Sleep's new Design Studio feature. Using it, you can select one firmness for the entire bed or a different firmness for each side. Firmness options available include soft, medium, and firm, individually for each side of the bed.
You pay with your credit card or via third-party financing. There are two third-party financing options available, Affirm and Zibby.
Every mattress comes with two free pillows.
It takes 2-3 business days for the mattress to be made and packed and a further 2-4 business days for FedEx to deliver it to you.
Shipping is free within the continental US. There are no deliveries to Alaska and Hawaii or international countries, at this time.
As I said, I’m surprised that the Smart Bed doesn’t cost more. It’s in the same price range as many other popular online mattresses like the Casper Wave.
Note that the prices below include the high tech Smart Cover, where all the magic happens.
You'll have 100 nights to sleep on your Smart Bed to decide whether it’s what you were looking for.
If you don’t like it, then contact Eight Sleep customer support and initiate a return. There’s no restocking, disposal or any other kind of fee on returns. Returned mattresses are either recycled or donated to charity.
You can decide to return just the mattress and keep the smart cover, too. They’ll deduct the cost of the cover from your refund.
The mattress is covered by a 10-year non-prorated warranty. The warranty applies only to the foam layers.
The smart cover is under a separate 1-year warranty, typical for most consumer electronics.
Visit Eight Sleep’s website to read the full warranty.
Eight Sleep ships via FedEx to all states within the US.
Shipping is free for the continental US. EightSleep does not currently ship to Alaska or Hawaii.
The mattress ships in 5-7 business days. This includes the time it takes to assemble and package the mattress. You’ll receive a tracking number as soon as the mattress is out of their facilities.
Expedited shipping is not available at the moment.
Delivery and Setup
Currently, Eight Sleep only provides curbside delivery. They will not take the mattress inside nor help you set it up.
But it should be pretty easy to unbox and unroll. Check the user guide that accompanies the mattress for instructions on setup and usage.
Note: The smart cover and mattress are delivered in separate boxes. You’ll need to download the companion app and connect the cover to your home WiFi to access the smart functions such as temperature control and sleep tracking.
Foundation and Frame
What type of bed frame/support does Smart Bed require?
Any foundation will do as long as it is sturdy. You can use a box spring, solid foundation, slatted frame or platform.
EightSleep also sells their own foundation made specifically for this mattress.
Does the Smart Bed work on an adjustable bed?
Yes, it does – except for split-configuration adjustable beds.
Care and Cleaning
Is a mattress protector needed for Smart Bed?
It’s not necessary, but it’s highly recommended. It will protect the cover from staining and the sensors in the cover from damage as a result of spills.
If you need to clean the cover either spot clean it or unzip the top layer of the cover and hand or machine wash it.
Do you need to rotate the Smart Bed mattress?
No, not necessary.
Aesthetics and Styling
The style of the Eight Sleep Smart Bed mattress cover is kinda subdued, due to the smart cover.
The mattress itself is white with a bright green trim. The Smart Cover is white at the top and grey on the sides. The smart cover goes on top of all of the beds (it fits on any mattress like a sheet would), it the mattress will look gray most of the time.
At only ten inches in height, the mattress doesn’t have a very imposing or luxurious look. It looks like any other ordinary mattress.
Unless someone sees the cable running to the socket or the connected hub, they wouldn’t guess how much technology is in the mattress.
Given all the tech in this mattress maybe you are expecting a complicated structure with all sorts of special materials and gizmos hiding inside. But it has a very simple all-foam 4-layer structure. All the tech smarts are on the cover.
Here are the four foam layers.
Comfort Layer: 2” reactive foam
This is a type of foam designed to have the responsiveness of latex and the pressure relief of memory foam. It hugs your body without feeling ‘swampy.’
Support Layer: 2” of memory foam
This layer enhances contouring and pressure relief. It molds the mattress to your body, ensuring you don’t experience any pressure points especially on your lower back, hips, and shoulders. It also ensures your spine is properly aligned.
Transition Layer: 2” of transition foam
A transition pad provides compression support and distributes your weight evenly across the mattress. It counters the sinkage from the softer foam layers above.
Foundation: 2” of high-density foam base
A firmer layer of foam provides overall support to the mattress. It also enhances compression support especially for couples and heavier sleepers.
In addition to the mattress itself, EightSleep also sells a Smart Cover and Sleep Tracker which work together to provide their smart mattress with its intelligent tracking features.
EightSleep's mattress Smart Cover consists of two sections.
There’s a technology layer, where all the sensors and gadgetry are embedded, and there’s a top layer which is the washable part.
The technology layer contains sensors that track your heart rate, respiratory rate, and movements during sleep. It even tracked REM sleep cycles. This layer also warms the mattress when you increase the temperature.
You control the functions of the Smart Cover and view your sleep data through the companion app, which is available for Android and iOS.
The Smart Cover is compatible with Amazon Echo smart speakers (directly) and other smart home devices like Google Home via IFTTT.
EightSleep's Sleep Tracker unit generates data and provides applications for you that help you make sense of your sleep patterns and improve the quality of your sleep, over time.
There's too much to unpack for this review, but some of the most important features the Sleep Tracker give you include:
- Dual-zone sleep tracking: each side of the bed gets their own independent sleep score with daily, weekly, and monthly breakdowns.
- Dual-zone temperature control. Each side of the bed can have its own level of warmth, too.
- A Smart Alarm that wakes you during the lightest sleep cycle within the latest half-hour range. So, for example, if you need to wake up by 7:00am for work, it may wake you at 6:42am. But if you are still in deep/REM sleep by 7:00am, then the alarm will still go off to ensure you get up on time.
- Direct integration with Alexa: Ask how you’ve slept, ask Alexa to warm the bed, etc.
- IFTTT smart home integrations with Google Home and other smart home devices. You can use this to, for example, turn on your Philips Hue Lights, start your Mr. Coffee Maker and adjust your Nest Thermostat when you wake up.
- Meditation and Ambient Sounds
The Sleep Tracker monitors a LOT of information about your sleep, using chest and other wired sensors inside the Smart Cover, including:
- Hours Asleep
- Heart Rate
- Breathing Rate
- Tosses & Turns
- Light Sleep vs. Deep Sleep (percentage)
- REM Sleep
- Bed Temperature
- Room Temperature
- Breaks (i.e. leaving bed to go to the bathroom)
- Separate sessions (i.e. if you take a nap lateron in the day)
So, if you have sleep apnea or just want to improve the quality of your sleep through science, then adding EightSleep's Smart Cover + Sleep Tracker makes a lot of sense.
By the way: if you end up buying another mattress, you can always purchase the Smart Cover w/ Sleep Tracker separately.
The Smart Bed mattress emits a slight smell when unpacked and needs a few hours to fully off the gas.
But the smell is not that strong – you may not even notice it. I
If it’s too much for you, then leave the mattress uncovered in a well-ventilated room for around 12 hours.
So… what is it like sleeping on a smart mattress?
Well, it feels pretty much like any other mid-budget foam mattress.
The Smart Bed has a typical memory foam cradling feel – much like Casper offers.
Support is great, although edge support could be better. This is a common problem with all memory foam mattresses, however.
Pressure relief is excellent, too – about typical for a memory foam bed. This is good news for those who have been experiencing punishing back pain from their old mattress.
Temperature control is also good, even without the smart cover. The mattress dissipates excess heat away from the mattress, but the memory foam retains just enough warmth for a comfortable snooze. If you want a warmer mattress, then the smart cover is a must.
The sleep tracking feature provides a lot of functionality, although some verified customers have complained that it doesn't always work, or it’s not the most accurate or it is hard to make sense of all the data. That said, it appears that many of these complaints have been resolved in EightSleep's most recent release, if their more recent reviews are an indication.
There is only one firmness option for the Smart Bed mattress: medium firm.
The medium-firm feels soft enough on top, but without getting too ‘swampy.’
There is just the right amount of firmness to support your weight without creating any uncomfortable pressure points. Although at only 10″ thick, heavier sleepers might want to look elsewhere.
Sinkage is average. It sinks enough to provide pressure relief but not too much that it compromises support.
Of course, the actual sinkage is going to vary among different sleepers.
A 200 lb person will feel more sinkage and experience a softer mattress. A lighter person will sink less and may experience a slightly firmer mattress.
Foam has very little motion transfer compared to springs or coils. Being all-foam, the Smart Bed mattress has minimal motion transfer. Your fidgety partner can turn all their want at night without waking you up.
The mattress itself has excellent cooling performance. It doesn’t trap much heat or odors.
If you want a warmer bed, the smart cover will cover that (no pun intended). Raise the temperature on your side or both sides of the bed using the app or by talking to Alexa or Google Assistant.
Pros and Cons
- Cool smart features to help you sleep better.
- Split-heating function solves a common couple's problem.
- Good support and pressure relief.
- Free shipping.
- Only one firmness choice.
- Plus size users may not get the support they need.
The Smart Bed Mattress is Perfect For You If…
- You want to monitor your sleeping habits and those of your partner.
- You prefer sleeping warm, but your partner doesn’t. Or vice-versa.
- You live in a colder climate. This mattress will warm you, but you can't cool it down.
If you think tracking your sleep via a smart mattress makes sense, then buy an EightSleep – they make the best smart mattress you can buy online.
It’s not all high-tech gimmicks, either. This mattress really does offer useful sleep monitoring features, and the mattress itself is very comfortable. And, based on recent reviews we've seen elsewhere, the company is clearly committed to listening to their customers and improving their products.
The price is surprisingly reasonable, too.
