Summary: Is the Eight Sleep Jupiter+ a Good Mattress?

Note: The Eight Sleep Jupiter+ has been discontinued, and Eight Sleep now sells two different mattresses, the Pod and the Smart Bed, both of which include sleep-tracking technology. Find warranty and returns information for your existing Jupiter mattress here.

The Eight Sleep Jupiter+ mattress is an all-foam bed, made with layers of synthetic latex, memory foam and polyurethane foam. All-foam beds are very common these days, but the Jupiter+ mattress is just the beginning: it's paired with Eight Sleep's Sleep Tracker, which slips on to the mattress in the same way you might put on a mattress protector. The sleep tracker was featured in a very successful Kickstarter campaign, and was developed in advance of the company's mattresses. The sleep tracker pairs with an app, which you can use to view data, monitor heart rate and nighttime breathing, and even control temperature -- you can use the sleep tracker as a heat blanket to warm up your mattress.

The Jupiter+Sleep Tracker system sells for $1,099 in queen size; the tracker itself sells separately for $399, so the mattress's price is competitive with other all-foam beds available online. So if you're interested in tracking your sleep patterns for health reasons, to improve athletic performance, or just for the sake of curiosity, the Eight Sleep Jupiter+ is a very good value.

We put the Jupiter+ mattress through our standard battery of sleep and comfort tests. We found the Eight Sleep bed to be well suited for our tester in  the three major sleeping positions, offering good support for back, side, and some stomach sleepers (heavier stomach sleepers should check our review on the Mars+ mattress).

The Jupiter+ mattress includes a 2' layer of very slow responding memory foam, and we did experience a good bit of that slow, melting into the bed feeling we associate with memory foam. Between the memory foam and the latex layer, both have a reputation for pressure relief, and our testing found this to be a strength of the Jupiter mattress.

Motion isolation was also excellent, making the Jupiter+ bed a very good choice for those who are sensitive to a partner's movements on the other side of the bed.

But the real story here is the mattress/sleep tracker combo. If you aren't particularly interested in analyzing your sleep data, then a number of other foam mattress compete directly with the Eight Sleep Jupiter bed on both materials and price. But as a sleep system, the Jupiter+ competes mainly with it's sister mattress, the Mars+ a foam-and-pocketed-coil hybrid bed that's more expensive than the Jupiter version.

Materials & Construction

What's in an Eight Sleep+ Mattress?

Overall, we classify the Jupiter mattress as a "Synthetic Latex and Memory Foam over Foam" construction type. This is a 10″ thick mattress comprised of 4 layers (listed below from top to bottom):

  • 2" synthetic latex, 3 lb. density
  • 2" memory foam, 4 lb. density
  • 2" polyurethane transition foam, 1.8 lb. density
  • 4" polyurethane support foam, 1.8 lb. density

The Eight Sleep Jupiter+ mattress features a 2" layer of synthetic latex on top. While not natural, this layer has the same pressure relieving and support qualities as natural latex. Under that is a layer of slow responding memory foam, followed by two layers of polyurethane foam.



The four layers of the Eight Sleep Jupiter+ mattress are wrapped in a soft and stretchy cover. Note that the Sleep Tracker then goes on top of the mattress cover.


Sleep Tracker

The "plus" sign in "Jupiter+" is for the included Sleep Tracker, the big selling feature from Eight Sleep. The tracker has several components. The 'receiver' that collects your data comes as a series of sensors embedded in a mattress cover that installs right on top of the Mars mattress (it goes on just like a mattress pad). You can see the wires and sensors in the cover, but our tester could not feel them at all. The top part of the cover unzips and is washable.

The mattress pad/sensor plugs into a small receiver unit, which in turn connects to an app, which serves as your dashboard and main interface for the sleep data that's collected, and also serves as a controller for the Sleep Tracker. For example, you can use the tracker as a heating pad, and set the app to start warming the bed at a certain time. You can even control both sides of the bed independently.


What can you  track with the Sleep Tracker? It can monitor your sleep, and tell when you are sleeping soundly or fitfully. It can tell you how often you wake up, your heart rate and respiration rate. It tracks total sleep time, and knows how long it took you to fall asleep. Based on the data, the app can make recommendations to improve your sleep quality. It can connect and sync with many other applications and trackers, and can be use to program the Sleep Tracker as a heating blanket.

Comfort & Feel

There are three aspects that make up our assessment of comfort and feel. We call these "preference-based characteristics" because no rating here is better or worse – rather, the attributes that are most desirable to you will be determined solely by your personal preferences. We apply the same classification standards to each mattress so you can more easily compare apples to apples.

Softness ( what’s this )

Keep in mind that what mattress companies call “firm” or “soft” is a purely a preference. All mattresses should be supportive and promote healthy spinal alignment. Whether a mattress is fluffy and squishy (what mattress companies call soft or plush), or less so (what companies call firm), is purely down to your personal needs and preferences.

We classify the Jupiter+ as a medium mattress, right in the middle.

Not sure what softness is best for you? Take our Mattress Match Quiz and find out.

Softness Level
(1=Least Soft, 9=Most Soft)
5 Medium


Cushioning Depth ( what’s this )

This refers to how deeply you sink into the mattress or feel cradled or hugged, versus a feeling of floating on top of the bed. This is definitely more of the latter. When we place our 16-lb. bowling ball atop the mattress, it did not sink in as much as it did with some of the other mattresses we’ve recently tested. And our tester, lying on top of the bed, felt cushioning was a bit shallower than some competing mattresses with deep pillowtops and plush top layers.

The Jupiter+ mattress (as well as its sister mattress, the Mars+) has what we would term medium cushioning -- average among mattresses, and a blend of floating vs sinking into the mattress.

Cushioning Depth
(1=Shallowest, 9=Deepest)
5 Medium


Responsiveness ( what’s this )

Responsiveness refers to how quickly a mattress recovers its shape after being compressed. When you press your hand into the mattress, for instance, then remove it, does it take several seconds for the mattress to return to flat, or does it recover immediately?

The Eight Sleep Jupiter+ mattress has 2" of synthetic latex (which is quick responding) and 2" of slow-responding memory foam under that. The latex effectively transfers the slow response of the underlying memory foam, so we did notice a lot of that slow, melting memory feel.

Response Rate
(1=Slowest, 9=Fastest)
4 Slow recovery, no bounce


Back Support & Pressure Relief

The two things that you should always be sure to get from your mattress are spinal alignment (commonly thought of as "back support") and pressure relief. Unfortunately, no mattress will deliver these two things equally well for all sleepers. In particular, spinal alignment and pressure relief capabilities will vary across sleepers with different weights, body shapes, and sleep positions. To help you determine how this mattress will perform for you, we break down our spinal alignment and pressure relief assessments by sleeper type.

In our evaluations, the Eight Sleep Jupiter+ mattress performed well in all sleeping positions for our tester. If you sleep in a variety of positions, or your partner sleeps in different positions that you, the Jupiter+ might be a good choice. We tested the Mars+ hybrid mattress and the Jupiter+ all-foam bed at the same time, so our observations contrast between the two. Generally, they are more similar than different.

Spinal Alignment

The key to good back support is maintaining proper spinal alignment while you sleep. This means that the mattress should hold your spine in roughly the same position it's in when you're standing. The ability of a given mattress to do this will generally depend on your weight, sleep position, and body shape.

Here is how we break down the spinal alignment of the Eight Sleep Jupiter+ mattress.

Weight Range Back Sleepers Side Sleepers Stomach Sleepers
Lighter <150 lb 9 9 8
Average 150 to 200 lb 9 9 8
Above Average 200 to 250 lb 9 9 7
Heavier >250 lb 8 9 6


Back Sleepers:

While our tester was on his back, he noted that his hips sank just deeply enough to create a perfectly neutral spine, while he felt the mattress did a nice job reaching up to support his lumbar curve. We feel that sleepers of a wide weight range would have a similar experience, and we did not have concerns that heavier sleepers might not be supported enough, with the possible exception of very heavy back sleepers (over 250 lbs.) who might experience hips sinking a little too much.

We found back sleeping support to be very good for both the Mars+ and the Jupiter+ mattresses, though our 200-lb. tester did have a preference for the firmer hybrid bed (the Mars+).

Side Sleepers:

For side sleeping, our tester also felt the Jupiter+ was supportive. He felt his shoulder sinking into the mattress enough to create good spinal alignment. He did feel that pressure relief was a bit better on the Jupiter+ mattress than the hybrid Mars+, but both mattresses performed well. If you are mainly a side sleeper, the Eight Sleep Jupiter+ mattress is likely the better choice.

Stomach Sleepers:

Achieving good spinal alignment for stomach sleepers can often be trickier as the hips can tend to sink down too far with some mattresses. Our tester felt well supported on his stomach on the Jupiter+ mattress, but did feel that people heavier than his 200 lbs. might sink in too far. So for those who sleep primarily on their stomachs and weigh over about 200 lbs., the Mars+ mattress is firmer, and would be a better choice.


Pressure Relief

When a mattress pushes back against your body with too much force in a concentrated area, the result can be pain, soreness, loss of circulation, excessive tossing, and other problems. In general, such "pressure points" are of greatest concern for side sleepers, since that's the position in which your body's weight is distributed over the smallest surface area. To find the right mattress for your needs, keep in mind that the pressure-relieving capabilities of any given mattress will vary depending on the sleeper. Factors like your weight and body shape (e.g., broader shoulders and/or hips) will determine how far you sink into the mattress, and the pressure relief offered by that mattress will vary widely at different depths.

Here's how we sized up the pressure relief of the Eight Sleep Jupiter+ mattress:

Weight Range Typical Curves Extra Curvy
Lighter <150 lb 9 9
Average 150 to 200 lb 9 9
Above Average 200 to 250 lb 9 9
Heavier >250 lb 9 9


Overall, we found the pressure relief offered by the Eight Sleep Jupiter+ mattress to be very good; 4" of latex and memory foam seemed to do a good job absorbing the pointy parts of our tester's body, and he had no issues with hot spots or joint stress. If pressure relief is a priority for you, especially if you are a side sleeper, we felt that the Jupiter+ would be a better choice than the Mars+ mattress.

Other Features

Beyond the preference-based characteristics of comfort and feel, and the body matching for spinal alignment and pressure relief, a mattress will have a number of other attributes that can make it a better or worse choice for you. We call these "priority-based characteristics" because they are areas in which a mattress can be better or worse, but that will have differing amounts of importance to each sleeper. So, determining how much importance to give to these features will be entirely a matter of your own personal priorities. As always, we apply the same ratings standards to each mattress so you can more easily compare apples to apples.


Motion Isolation ( what’s this )

With a bowling pin standing upright on the Eight Sleep Jupiter+ bed, we tested motion isolation by dropping a 16-lb. bowling ball on it, as well as the whole weight of our 200-lb. tester.

In both tests, the bowling pin barely moved, so we feel that the Jupiter+ bed would be a good choice for couples who don’t want to feel their partner getting in and out of bed.

Motion Isolation Rating 10 /10 Good


Temperature ( what’s this )

Foam mattresses, particularly slow responding memory foam mattresses, have a reputation for feeling hot. The Eight Sleep Jupiter+ mattress doesn't have any particular features to combat this (some competing foam mattresses include gel or graphite in their memory foam, or include phase-change material in the mattress cover). If you have a known issue of sleeping hot, then it may be worthwhile to explore other options. For people that don't experience this issue, we don't expect the Jupiter+ to be any better or worse than other foam beds.

One thing the Jupiter+ has going for it is its medium cushioning; you do not sink deeply into this bed, so more of your body is exposed to air.

Stays 'Cool' Rating 5/10 Average among foam beds


Edge Support ( what’s this )

If you like to sit on the edge of your bed, or if you tend to sleep right on the edge of your mattress, edge support will be an important preference factor for you. All foam mattresses, in general, do not have a good reputation for solid edge support, and the Eight Jupiter+ is no exception. When sitting on the side, our tester sunk through most of the mattress, though did not feel unstable. When laying on the edge, he felt he was starting to lean off, though not so much he felt he would actually fall out.
If you need the very best edge support, other mattresses, including the Eight Mars+, have done better in our tests.
Edge Support Rating 6/10 Average for a foam bed

Ease of Repositioning ( what’s this )

Memory foam mattresses can sometimes make movement challenging (some people compare it to the feeling of rolling out of a hole). On the Jupiter+, our tester felt it took a slight effort to change sleeping positions, but he never felt hindered or prevented from rolling over. So especially for a memory foam mattress, ease of repositioning is very good.

Repositioning Rating 8 /10 Very good


Green Features ( what’s this )

For mattress shoppers concerned with the use of natural materials, sustainable manufacturing practices or the like, we offer our subjective evaluation of any efforts taken by the company to make the mattress more green, healthy, or safe. 

In the case of Eight Sleep, the company makes no claims about the use of natural materials, and is up front that its latex foam is synthetic. All of the foams used are certified to the CertiPUR-US standard, which verifies that a material has low VOC off-gassing as well as a lack of chemicals and other substances regulated by the CPSC.

Green Rating 5 /10 Does have some safety certifications


Adjustable Base Compatibility ( what’s this )

We did not specifically test the Eight Sleep bed with an adjustable base. However, the company does say that it can be used on one, and it does sell an adjustable base.

What Are You Getting?

The Eight Sleep Jupiter+ is a 10-inch mattress made of layers of synthetic latex and memory foam, with a support layer of polyurethane foam.  But the big story is the included Sleep Tracker, which transmits sleep data to an app, which serves as a dashboard and controller for the tracker. Each side of the bed can be tracked independently, and the tracker can also be used as a heated blanket. The app can be set to start warming the bed at a designated time.

How Long Will the Eight Sleep Jupiter Mattress Last?

When it comes to estimating the comfort lifespan of a mattress, we tend to use foam density as our best, albeit imperfect, predictor of how long a foam will retain its shape and resiliency. For the Eight Sleep Jupiter+ mattress, the top layer of synthetic latex is of 3 lb. density, with the memory foam layer at 4 lb. density. Those are both above average for mattresses in this price range. The other foams are 1.8 lb density, typical for support foam. Overall, we don't see any red flags as far as durability.


Overall Value

If we consider just the Eight Sleep Jupiter mattress, without the sleep tracker, and subtract the $399 price of the sleep tracker from the Jupiter+ system, we end up with a $699 all-foam mattress. Among online mattresses, there are plenty of examples of all-foam beds in this price range, but not many with the specific combination of synthetic latex and memory foam. Even considering the mattress alone, we think it's an excellent value when compared to other online mattresses, and certainly a good value compared to what you would find in mattress stores as well.
In our performance tests, we noticed subtle differences, but the Mars and Jupiter mattresses have more in common than they do differences, so check out our review of the Mars+ if you are considering the Jupiter+.
Value Rating 9 /10 Excellent value


Other Factors to Consider


  • Free delivery 

Eight Sleep includes free delivery, which is not particularly unusual among its competitors.



  • 100-day trial period
  • Full refund

Eight Sleep offers buyers a 100-day trial period. Returns within the trial period are free, but you'll need to provide proof of donation or disposal. Eight Sleep will help you find a place to donate the mattress.



  • Warranty Length: 10 years
  • Indentation Coverage: 1” and above

One of the biggest, if not THE biggest complaints about any mattress from consumers regards body impressions—the inability of a mattress to spring back, eventually creating a low spot/sinkhole in the mattress. As such, mattress warranties all contain a term defining how big a sag or ‘body impression’ (measured when no one is on the mattress) is considered a defect, and thus covered under the warranty. The industry standard for innerspring mattress is 1.5”. Eight Sleep has chosen to cover indentations that meet or exceed 1”. Practically speaking, that means any softening or sagging would need to be at least that deep before the warranty would offer you protection.


Bottom Line: Is the Eight Sleep Jupiter+ Mattress Right for You?
