Eight Sleep Pod Assessment


A well-built mattress/sensible mattress with  built-in heating and cooling system with preset choices that may be adjusted at will. An integrative sleep monitoring app gives quite a lot of metrics together with HR, mattress temperature, sleep/wake ratio, REM/SWS/mild sleep phases, respiratory fee, and nocturnal motion.

The great:

  • Straightforward meeting with in-app instructions
  • Intuitive, simple to make use of app
  • Pre-programmable begin/finish capabilities
  • White noise generator built-in the app
  • Sensible alarm operate
  • Sensible house appropriate – Alexa/Hue Lights/Wemo Espresso/Thermostat integration potential
  • Exterior of the mattress, the pod and canopy are light-weight and will simply be tucked right into a carryon for journey

Not so good:

  • Heating and cooling capabilities generally work too nicely (beta expertise is already being developed to repair this in future app updates)
  • The hub should be related to Wi-fi always – a priority when you’re bothered about EMF publicity relative to sleep high quality
  • Sometimes the accelerometers and strain sensors have a tricky time distinguishing motion between two people utilizing the identical mattress and as such, this will skew the person’s particular person sleep metrics

Our ranking: 4.8/5

First Impressions

For starters, I have to complement Eight Sleep on their excellent customer support. I used to be honored to have two staff members from Eight Sleep make a private go to to assist with organising the Pod.

Clearly the corporate wished the assessment to go easily, however because it turned out, organising the Pod with the in-app instructions was virtually seamless.

The mattress itself is a Four tier microplush foam design with differing layers of density to offer assist and luxury whereas permitting for dissipation of warmth. It was shipped in a 4’ by 1’ field however take note it’s possible you’ll want some help if shifting the product upstairs as it’s near 60 or 70lbs.

Eight Sleep Pod Review - Unboxing

The mattress itself was enveloped in a single woven outer layer, upon which the stitched mattress topper was zipped onto (as proven within the image above – see uppermost darkish grey layer).

The hub was pretty small and resembled the scale of a median pillow. Even when working at 100% capability it was quieter than an air conditioner or white noise machine. While you begin to run low on water, the app rapidly alerts you and saves you the trouble of getting to test day by day.

Pairing with the wi-fi router was foolproof and the priming course of was really easy even a caveman might do it (shout out to all of the GEICO followers on the market).

General the development was exceptionally sturdy and in comparison with another sleep expertise I’ve used previously, this was lightyears above them. I’ve but to come across anything in the marketplace which compares to the hub when it comes to general capabilities.

All in all, I used to be extraordinarily happy with how a lot time and thought had been put into the product.

Execs & Cons

My background is sport science.




Development evaluation.

I wish to know the “why” behind the “what”.

 After we encounter physiological modifications, information can usually assist to offer us with potential hypotheses to elucidate what’s occurring and why.

If you happen to’re not acquainted with sleep monitoring expertise, it’s scorching proper now. Like REALLY scorching, particularly on this planet {of professional} sport, efficiency enhancement, or biohacking.

Even when somebody has little interest in lifting weights, consuming a nutrient wealthy weight loss plan, or optimizing their life-style for optimum well being, everybody needs to sleep nicely. Why? Poor sleep actually wrecks each side of your life. While you don’t sleep nicely, you actually flip right into a strolling zombie.

So, if you may get a generalized concept of what’s happening “beneath the sheets” so to talk, this will probably level you in the correct path of what to vary.

Right here’s what you’ll see with a single night time of sleep whereas utilizing the Eight Sleep mattress and app.

Eight Sleep Pod app sleep staging metrics

The whole lot from time in mattress to physique temperature, coronary heart fee, motion, and every thing in between.

If you happen to’re curious concerning the precise metrics and the way they’re calculated, listed below are just a few to present you an concept of what the algorithm components into your sleep health “rating”:

  • Eight Sleep Rating = Time slept x Toss & Turns
  • Variety of hours slept
  • Variety of interruptions (i.e. sleep fragmentation)
  • Sleep stage continuity
  • Quantity of deep sleep

A number of information however no path?

It appears we’re at a really thrilling level on this planet of medication, sport, health, and well being. We have now an inordinate quantity of expertise which might monitor physiological metrics and supply early warning indicators if damaging traits persist.

Information is nice because it gives us with the means to an finish – change. If you happen to alter one thing, how have you learnt it really works? Information.

Nonetheless, when you’re simply monitoring information to have it, then it’s primarily nugatory and solely compounds the ever-growing anxiousness over a lower than optimum rating of any metric.

That being stated, I’ve observed some very attention-grabbing modifications in my private information with the metrics from Eight Sleep.

For instance, one of many very first issues I observed was the distinction in REM and deep sleep which my spouse and I shared regardless of sleeping in the identical environmental situations (cool, darkish room, no electronics, white noise machine, and many others.). Have a look under, she’s on the left and I’m on the correct.

Eight Sleep App Pod Sleep Staging

In a single night time she’s experiencing virtually TRIPLE the REM sleep that I’m getting.

Granted that is solely a single night time of knowledge however the pattern was current over quite a lot of nights – she was persistently getting an exponentially bigger quantity of REM sleep every night time.

Now, that raises an important query – is the big enhance in REM resulting from the truth that she is sleeping “higher” (abitrary assertion at greatest and difficult to quantify)? Or is her physique experiencing the next demand for REM sleep resulting from her life-style and the cumulative burden of stress which she encounters day by day?

With out entry to different metrics corresponding to bloodwork and even her subjective notion of fatigue, it’s very powerful to reply that query.

However, it’s quite intriguing, no?

Nonetheless, being the scientist that I’m, I began testing just a few issues. I routinely wish to make myself the guinea pig and see what occurs. All within the title of science, proper?

Under you’ll see Four nights of knowledge – the highest 2 nights have been routine work days with none train or extra sleep aids. I might characterize my sleep as mediocre to average at greatest. I slept however didn’t dream and I wakened feeling about the identical as I did after I went to sleep.

Now, when you have a look at the 2 images under that, you’ll discover that my REM and deep sleep have each DOUBLED.

So, what did I alter? On one of many days I lifted weights for about 90 minutes and the opposite day I utilized 500mcg of sublingual melatonin coupled with 200mg of L-theanine.

Even with out the info, I might have advised you that my sleep was drastically totally different simply in the way in which I felt. However, the info validated that change and helps me to know what does or doesn’t enhance my sleep.

Not solely that, with the appearance of the pod, you’ll additionally discover the Eight Sleep app features a digital sleep teaching interface which walks you thru your sleep every night time and offers some perception into what’s occurring, why it’s occurring, and the best way to repair it.

If you happen to’re sleeping poorly and unsure what to do about it, that is going to be indispensable.

However what about validity & reliability?

I can hear the citizen scientists on the market proper now: “How do we all know that is really monitoring what we predict it’s monitoring (i.e. validity)?”

At present Eight Sleep is present process medical trials with a lot of native hospitals within the NY space and the metrics from the hub are being straight in comparison with EEG information from sufferers inside sleep research.

As these research are launched we’ll have a a lot better concept of the validity and reliability behind this actual product and the expertise that it holds. Nonetheless, within the meantime, be happy to dig into the literature on strain sensors and tri-axial accelerometers as each have been studied extensively inside the world of sleep science.

Eight Sleep additionally has a medical advisor staff boasting PhDs and MDs who presently observe, mentor, and educate inside the realms of neurobiology, psychiatry, sleep drugs, cognitive behavioral remedy, circadian rhythms, and sleep physiology.

A number of negatives…

Realistically there have been solely three negatives I encountered with the unit and most are seemingly inconsequential:

  1. Bother deciphering metrics between two our bodies
  2. Incapability to run the unit with out Wi-Fi
  3. It really works too nicely

Let’s dive into them each…

Metric Combine-ups

Sometimes my spouse and I discovered that the sleep tech wasn’t at all times in a position to decipher correct wake instances when certainly one of us left the mattress ahead of the opposite. For instance, there have been just a few days after I would come up 90-120 minutes earlier than her however my sleep information would declare that I stayed asleep till she lastly acquired up. I’m guessing this may increasingly have been resulting from the truth that we have been each sleeping close to the middle of the mattress and thus it’s powerful for the tech to discern when one physique moved if each are place in a centralized location.

Now, from a sensible standpoint, does this actually matter?

For my part – no, completely not.

Whereas it could skew your sleep information barely this in all probability occurred as soon as each 8-10 days and within the grand scheme of issues, not likely a giant deal.

Wi-Fi or No-Fi

If you happen to’re within the realm of sleep enhancement, then you definately’re in all probability conscious of the info which has surfaced over the past 10 years documented the affect of wi-fi expertise (Bluetooth, Wi-Fi, generalized EMF, and many others.) on mind wave patterning.

So, as a basic rule of thumb, I often flip off our Wi-Fi nightly and anecdotally I’ve observed fairly a distinction in my sleep (the clientele whom I work with discover related advantages as nicely).

Nonetheless, the hub capabilities primarily off Wi-Fi transmission as soon as it’s linked to your router. As such, it received’t work with out a wi-fi sign. Not solely that, your nightly information is shipped to the Eight Sleep servers the place it’s compiled for information evaluation and longitudinal sleep traits.

So, I’ve been leaving my Wi-Fi on whereas utilizing the hub to permit for changes by way of the night time, however I nonetheless place my telephone on airplane mode whereas charging subsequent to my mattress and my sleep appears to be average in the interim.

Sooner or later, it might nice to see Eight Sleep devise a piece round for this which permits the system to operate impartial of Wi-Fi by way of the night time after which reconnect every morning as soon as it had been turned again on.

Once more, this received’t be a deal breaker for most folk as 99% of the inhabitants has no concept how EMFs have an effect on their sleep. Nonetheless, if that is one thing which is essential to you (and hopefully it must be if you wish to maximize your sleep), then it’s possible you’ll wish to take into account how one can scale back EMFs throughout the night time whereas nonetheless utilizing the thermoregulatory parts of the hub.

Excessive Effectivity

I’m usually a fairly scorching natured sleeper. As a bit child, I might continuously complain to my mother about “scorching socks” in the midst of the night time which woke me up. As such, to this present day I nonetheless can’t sleep in socks.

Naturally the temperature management features of the Eight Sleep expertise have been exceptionally intriguing given my historical past. For one, I usually get up resulting from poor temperature regulation all through the night time and two, analysis has proven that the mind must drop 2-3° as a way to induce sleep and keep particular levels of sleep. Thus, the hub may very well be drastically useful with this.

Nonetheless, I set the hub on -1 (+10 is hottest and -10 is coldest) and located myself waking up repeatedly by way of the night time resulting from my pores and skin being exceptionally chilly. Now, it’s February and whereas my spouse does preserve the warmth cranked up, I’m guessing it could be too chilly throughout the night time because the ambient temperature drops outdoors coupled with the cooling from the hub.

Sensible temperature

Eight Sleep is presently nonetheless engaged on the Sensible Temperature management setting all through the night time. This might primarily permit the person to set a particular temperature and the hub would keep that given temperature through heating or cooling results to reinforce one’s sleep cycles.

Additionally, this sensible temperature software would slowly heat the temperature of the mattress previous to your alarm as it will naturally stimulate the physique to get up with out mild or sound.

Nonetheless, in my thoughts the true query is that this: does the physique naturally change temperatures all through the night time as a result of corresponding metabolic and physiologic processes that operate throughout totally different levels of sleep? If that’s the case, would a constant ambient temperature negatively alter this atmosphere?

I don’t know if we’ve got a solution for that but nevertheless it’s definitely attention-grabbing to think about and one thing you monitor inside your Eight Sleep metrics when you select to make use of that possibility sooner or later.

Pricing and availability

Nobody in the marketplace presently has something just like the Pod. There are some firms providing heating or cooling programs, not one has sought to mix every thing fairly like Eight Sleep’s new innovation. As such, it’s almost not possible to match different producers given it’s virtually apples to oranges.

That stated, Eight Sleep are undoubtedly pitching The Pod on the mid/higher finish of the market. The general worth level of The Pod programs  will depend on which dimension mattress you select and are as follows:

  • Full ($1,995)
  • Queen ($2,295)
  • King ($2,495)
  • Cali King ($2,495)

Delivery is about to begin in April 2019, and also you’re in a position to reserve your Pod for a $95 down-payment. Finance can be obtainable from $110/month with 0percentAPR $zero deposit. As with most direct to client mattresses as of late, Eight additionally presents a 100-night trial and free returns

Personally, I assumed the mattress was a bit agency for my style (my spouse cherished it nevertheless). We swapped the EightSleep mattress for our different barely softer king sized model, added the thermoregulatory cowl, and personally I feel it’s a lot better.

So, when you’re debating on which mattress to get, I might counsel upgrading by not less than one mannequin (if no more). You actually spend 33% of your life asleep so if there’s one factor you shouldn’t skimp on, it’s your mattress.

Make investments properly and your sleep can pay with wealthy dividends.
