This New York City-based company was founded in 2014. A noticeable difference with Eight is that they are a tech company that develops smart mattress technology. At Eight they believe they can measure, understand, and optimize the way you sleep helping you to achieve a happier and healthier life.

Their team of innovators and dreamers is working tirelessly on developing mattresses that will adjust to our individual needs in real time, enabling us to experience maximum recovery while we rest.

Eight has packed so much technology into these mattresses that they no longer call it a bed; it’s an experience.

Product Offering

Eight offers a variety of mattresses in foam and foam with pocket-spring coils. They break it down into the “smart collection” containing all their technology and the “standard collection,” the same quality mattress minus the smart tech.

Smart Collection

THE SATURN+ – This is the most affordable smart mattress in their line. SATURN+ is made of a durable foam that measures 10’ tall and contains three individual layers.

The mattress has a medium-firm firmness and comes with “smart technology” that tracks over 15 factors about your sleep, including deep sleep, heart rate, and respiratory rate. All of Eight’s smart mattresses integrate with your smart home technology including Alexa, Nest, and Philips Hue.

THE JUPITER+ – This is the most popular smart mattress in their line. Made of a premium quality foam containing 10’ tall foam the Jupiter+ has four layers.

This mattress has a medium firmness and minimal movement transference to help limit interruptions during sleep. That additional layer of foam is meant to limit the amount of movement between sides of the bed.

THE JUPITER+ also comes with “smart technology” that tracks over 15 factors about your sleep, as well as two zones of temperature control that is controlled by your phone. This mattress has the full smart home integration as well.

THE MARS+ – Referred to as the “Rolls-Royce” of mattress technology. This mattress is Eight’s premium brand containing a hybrid of sleeved coils and soft foam layers for medium-soft firmness and maximum breathability.

This mattress is 11” tall with four layers of reactive foam and innerspring coils. THE MARS+ will not transfer motion, and it contains all of the “smart technology” of the previous versions. This mattress also has a smart alarm that detects when you are in light sleep to trigger your alarm at the best time for your body to wake up.

Customer Support

Eight Sleep has a full customer support center that contains an extensive Q&A area answering all types of questions from “Do I need to flip my mattress?” to “Are there chemical fire retardants in the mattresses?”

In addition to questions about the mattresses and technology, there is also a section for shipping and returns.

They offer an email and a toll-free number to contact their central office in New York City.

Sleep Trials, Warranties & Return Policy

Eight offers a 100-night trial program. If you are unhappy after 100 nights of sleep on an Eight Mattress, they will send someone to remove the mattress from your home for free. You void the trial program if the mattress leaves to the US. They do have a showroom called the Eight Suite where you can schedule a day to test out their mattresses.

The warranty on Eight’s mattresses is subjective to the type of mattress you bought. The company offers a ten-year limited warranty that applies to the mattress only. The warranty covers you from defects and manufacturing issues.

The technology portion of the mattress is covered exclusively by a one-year limited warranty. There is a ton of additional criteria that can void the warranty. You must have proof of a firm foundation and sufficient support. The mattress cannot have any tears, stains, odors, footprints, or signs of jumping on the bed. The company will inspect the mattress for these criteria before issuing a refund or replacement.

For returns, email the company, and they respond within 1-2 business days. They then schedule a removal and issue you a refund within 2-3 business days. The sleep tracker that comes with the mattress must be returned by mail to the central office.

Reviewed: The Jupiter+

The Jupiter+ is by far the most popular smart mattress designed by Eight. With 724 4+ star reviews this is the go-to mattress for those looking for a comfortable rest and the smart home technology of the future.

What Sizes Are Available?

The Jupiter+ is available in four different sizes. Below are the dimensions for each mattress.

  • Full: 54 X 75 X 10 inches
  • Queen: 60 X 80 X 10 inches
  • King: 76 X 80 X 10 inches
  • California King: 72 X 84 X 10 inches

What’s It Made Out Of?

The Jupiter+ is a premium high-density foam, and the material is broken down into four layers.

The first layer is two inches of latex-like foam. The goal is for the foam to have the flexibility of latex but also be hypoallergenic and provide proper support, breathability, and fire retardation.

The second layer is two inches of memory foam which provides the right comfort and support to give you the feeling of being hugged while you rest.

The third layer is two inches of transition foam. This layer is meant to equally distribute weight and let the mattress adapt to your sleep position.

The fourth layer is four inches of support foam to guarantee the right support and durability of the mattress.

All of Eight’s foams are CertiPUR-US approved which means they are:

  • Made without ozone depleters
  • Made without PBDEs, TDCPP, or TCEP flame retardants
  • Made without mercury, lead and other heavy metals
  • Made without formaldehyde
  • Made without phthalates regulated by the Consumer Product Safety Commission
  • Low Volatile Organic Compound emissions for indoor air quality

At the top of the Jupiter+ is the technology layer. This portion adds the feature unique to Eight mattresses. This layer tracks your sleep, heats each side of the bed at a different temperature, wakes you up at the lightest moment of sleep every morning, and lets you connect your mattress to other smart home devices as well as your smartphone.

Is This Mattress Good For Me?

Everyone sleeps differently, so not every mattress will work for everyone – no matter how good it sounds. This section will break down your unique sleeping patterns to see if Eight’s Jupiter+ will work for you.

Side Sleepers

Yes, the top two layers of the mattress will not only contour perfectly to your body shape but will also provide the support and flexibility to grip you every time you rest.

Stomach Sleepers

Where Can I Buy It?

All of Eight’s mattresses are available online at their site Eightsleep.com. If you want to find their mattresses somewhere else online, they are also on Amazon.

In addition to online sales, Eight also sells a lot of mattresses at their showrooms in Minneapolis, Minnesota, and New York City, New York. At these locations, you can try out all the mattresses in their “Sleep Suite.”

How Much Does the Jupiter+ Cost?

The Jupiter+ is priced affordably at around $1,049 for the queen. They also offer 0% interest financing on their website with payments as low as $58.00 per month.

If you are interested in having all of the comforts of a high-quality mattress, but you feel the technology isn’t necessary – you can pick up The Jupiter mattress for around $549.00.

All of Eight’s mattresses also come with two free pillows.

Is It Worth It?

The Jupiter+ design keeps the consumer in mind. The intelligent placement of contouring foam beneath the poly foam allows you to enjoy the benefits of memory foam while maintaining mobility and firmness.

The foundational four inches of support foam serves as a durable and breathable foundation that allows the mattress to maintain its shape.

Eight Sleeps mattresses all do a great job of offering support to pressure points for stomach and side sleepers. The Jupiter+ is no exception, the first layer of polyfoam provides the right amount of firmness that will meet the contour of your body giving you the most comfort possible.

As for the temperature control and breathability of the Jupiter+, the mattress maintains its temperature very well and can cool down or heat up within minutes.

You also get a 100-night sleep trial which is becoming increasingly popular as an industry standard, but it is very nice. It’s hard to make a real decision on a mattress without seeing how it affects your life. With this sleep trial, you will get to apply plenty of testing.

The cost of the Jupiter+ is a major selling point; you get years of technology and innovation packed into a mattress at prices that compete with standard memory foam mattresses. Also, if you don’t have all the money upfront, they offer available interest-free payment plans.

This mattress is an excellent choice for people who tend to sleep hot, suffer from soreness and pressure points, and those who want to reduce motion transfer from a sleep partner. The sleep tracker also offers a slew of information about your sleeping patterns, heart rate, body temperature, and deep sleep periods.

Let’s break down some of the technology into more detail to show you precisely what separates Eight’s Jupiter+ from the rest.

The mattress will take a variety of criteria and give you an overall sleep score. Once you get into bed, the tracker will start analyzing your breathing, movement, heart rate, and temperature to determine when you fall asleep, toss and turn, and enter into the deepest, most restorative stages of sleep.

At the end of your sleep, you will also get a deep sleep score. This score is necessarily the percentage of time you spend in REM sleep throughout the night. The app will show you how factors such as room temperature, outside noise, and movement affect your sleep.

Shipping Info

All Eight Mattresses are made to order from their Chicago manufacturers in the United States. Shipping from the US ensures top-notch quality and security.

All mattresses are prepared as ordered so shipping takes about 7-10 days.

Each Eight Smart Mattress comes in two boxes: The taller and more prominent box where the foam part is compressed, rolled, and put in is 16” x 16” x 46” (as a reference point, it is about the size of a golf bag), while the technology layer comes in a 17.5”x22”x12” box. The taller box is about 90 pounds while the technology layer box is about 17 pounds.

Best Bed Frame/Foundation for The Jupiter+ Mattress

Eight Sleep does not recommend any specific foundation. They say their mattresses will work on a variety of different surfaces including slats, platform beds, box springs, and even the floor. They just recommend keeping no gaps wider than three inches between the supporting beams of your foundation.

Eight mattresses will also work on adjustable bases as long as the base moves the whole mattress and not just one side. Because there is a cable connected to the hub of your smart mattress you should make sure the wire will not get trapped in the adjustable base as it moves up and down.

They offer an email support@eightsleep.com for any questions regarding choosing a foundation for your smart mattress.

Reasons NOT to Buy a Jupiter+ Smart Mattress by Eight

There are many good things to be said about this mattress and not too many bad comments are present.

One of the significant complaints a lot of people have is the offgassing that occurs when you first open up the mattress. It is recommended by some to let the mattress air out for 48 hours before using it.

Similar Brands

Comparative to the Eight Jupiter+, the Sleep Number Sleep IQ offers individual zone technology with support adjustments. The Sleep IQ contains five zones of contouring support with a two-inch PlushFit foam that supports all weights and sizes.

The big difference between these two mattresses is the Sleep IQ has a reputation for sleeping a little hot especially in the warmer months, and a little too cold during the winter months.

Sleep Number offers a 100-day trial as well, and the price points between the two mattresses are similar.

The ReST Bed is another innovative smart mattress that allows you to control the firmness across five areas of your mattress. The technology responds automatically to pressure points and adjusts as you move.

This mattress is excellent for couples who prefer different levels of firmness and people experience pain in a particular area of their body. You have the freedom to make the part of the bed where your pain is softer when you need it.

As for price with The ReST Bed, for a queen, it runs about $2000 more than the previous two mattresses at roughly $3,999. It is one of the most technologically advanced mattresses ever created.

The last mattress we’ll take a quick look at is the Reverie Sleep System. Their mattresses are a foam spring material that requires you to adjust the foam springs to your desired location.

The one major thing that separates Reverie from the Eight Mattresses is they offer one year of sleep support from a “sleep coach” that provides ongoing sleep tips to help you get the best experience possible.

The price point for the Reverie mattresses is considerably higher than most of the others on the market ranging from $2,249 to $5,500.

Reverie is one of the only online mattress companies to offer no sleep trial and no returns of any kind. Given the cost of the mattresses, this is a considerable risk that many customers may be unwilling to take.


Overall, it’s challenging to compete with the Eight Brand of mattresses. The quality of the mattress and sleep is very high, each of the layers of foam is assembled with a purpose.

The memory foam and polyfoam layers provide the comfort and flexibility you need to get a comfortable night sleep. These layers also give you the motion transference that ensures you are not interrupted while you sleep. The lower four inches of foam offer the support the mattress needs to withstand years of use.

The technology is what makes this mattress one of the best. For the price range, no mattress can compare with the sleep tracking technology that will help you sleep better as time goes on. You will learn a lot about your patterns that you never thought you would know.

Eight manufacturers all their mattresses in the US, and you can contact them directly to speak with a live person.

The fact that Eight offers a 100-night trial takes a lot of the fear out of purchasing a mattress online, and if you are still skeptical you could always go to the “Eight Suite” and try the mattress out for yourself.

The Eight Jupiter+ is a luxury mattress with the price tag of an economy mattress. They have pulled out all the stops and provided a mattress that is comfortable, supportive, and educational. If you want to learn how to improve the quality of your sleep, look no further than The Eight Sleep brand of mattresses.
