Eight Sleep Pod 3 evaluation: The excessive value of nice sleep

I’ve all the time tried to get as a lot sleep as attainable, however now that I even have a one-year-old to take care of, something that may also help maximize what little relaxation I do get is priceless. So once I heard that Eight Sleep was popping out with a new edition of its good mattress topper that gives higher sleep monitoring and temperature controls, I used to be curious to see how nicely it labored. And whereas the Pod 3 Cowl is costly, after a number of months of testing, I by no means need to return to an everyday standalone mattress.

The Eight Sleep system

The corporate’s core choices encompass two fundamental parts: The Pod 3 Mattress and the Pod 3 Cowl. The mattress itself is comparatively simple. Its encompasses a medium firmness that is a bit stiffer than one thing like the unique Leesa mattress and it contains varied further layers for higher warmth distribution.


  • Extra delicate sleep monitoring
  • WiFi now helps 5Ghz networks

  • Autopilot and Information Perception options require 8+ Professional subscription

The Pod 3 Cover works with both Eight Sleep's mattress or the bed you already own via the company's PerfectFit encasement.

Then there’s the Eight Sleep Pod 3 cowl, which is each the guts and the brains of the corporate’s two-pronged strategy. To be able to ship your good sleep temperature, the quilt options what Eight Sleep calls an Lively Grid, which is actually embedded tubing that carries cool or heat water to your aspect of the mattress. There are additionally sensors constructed into the Lively Grid that may monitor issues like your coronary heart charge, sleeping respiratory charge, how a lot you toss and switch and extra, with Eight Sleep claiming that the Pod 3 provides considerably extra correct monitoring than its earlier choices. After which hooked up to the Lively Grid is the Hub, which serves each as a reservoir for the water within the Pod Cowl and as a spot to deal with essential tech like WiFi, which not like earlier fashions now helps 5GHz networks.


Whereas the considered having to plug wires and hoses into your mattress would possibly seem to be a bit a lot, getting the whole lot working is definitely fairly easy. Like a number of foam mattresses, Eight Sleep’s choice arrived compressed in a field — all you might have to do is take away the plastic wrapper and provides it a number of minutes whereas it expands. The good factor is that you simply needn’t purchase one from Eight Sleep in any respect, because the Pod Cowl is designed to work just about any mattress as much as 16 inches thick.

The Pod Cover's Hub functions as a reservoir for sending cold or hot water to your bed and also houses important components like built-in WiFi.

That is as a result of whereas the usual Pod Cowl comes with zippers that line up with matching tooth on the corporate’s mattress, you may as well order the Pod Cowl with PerfectFit, which incorporates an encasement that accommodates third-party beds. So in the event you already like your present mattress, you needn’t toss it to put in the Pod Cowl. Not solely does this decrease the worth of entry, it is also a welcome transfer towards normal flexibility. Which is nice as a result of beginning at $2,045 (for a full), this factor positively ain’t low cost.

As soon as the Pod Cowl is hooked up to your mattress, Eight Sleep’s app gives easy step-by-step directions on easy methods to join the hose, fill the reservoir and energy it up. Admittedly, there’s not rather a lot to mess up (other than possibly not leaving sufficient room behind your mattress to forestall the hose from kinking), however the information removes all of the guesswork. And whereas the hub itself does take up a bit of house, the hose is lengthy sufficient that it isn’t too troublesome to search out a spot for it. From there, you may arrange or signal into your account, enter your WiFi information and that is it. All instructed, it took me lower than 20 minutes to place the whole lot collectively after unboxing it.

The tech

The Pod Cover uses a variety of sensors to track things like your sleeping heart rate, respiratory rate and more. And in the morning you get a full report along with a daily sleep score.

Whereas the Pod 3 Cowl is not an enormous departure from earlier fashions, it does just about the whole lot very well. The sensors made straightforward work of monitoring my sleeping coronary heart and respiratory charges. And because of charts and graphs which can be accessible contained in the app, it is simple to see how varied aspects affect your sleep. You even have the flexibility so as to add tags for issues like stretching, caffeine consumption and others to raised correlate your daytime actions with the quantity of relaxation you get. And each day, the app spits out a sleep rating to let you know how you probably did.

The opposite large a part of the Pod Cowl’s equipment is its heating and cooling tech. The quilt helps dual-zone controls, so you may set the temp for every half of the mattress independently. That is very nice as a result of whereas I sometimes favor issues on the cool aspect, my spouse is usually chilly at evening and has her aspect set to heat. Truthfully, even with out all of the sleep monitoring, the Pod Cowl is value it for its cooling and heating alone.

In the Eight Sleep app, you can set your beds temperature to various degrees of hot or cold, while the optional Autopilot features (which requires a $19 monthly subscription) can adjust temperatures automatically.

At this level, the science is fairly clear, your thermal setting has a big impact on how nicely you sleep. Too sizzling or too chilly and also you’re nearly actually going to get up feeling much less rested. However with the Pod Cowl, you may choose your good temp and set a schedule for controlling heating and cooling ranges all through the evening. For me, it is like laying on the cool aspect of the pillow, besides on a regular basis and throughout your entire mattress, which makes an enormous distinction in each how briskly I go to sleep and the way I really feel the subsequent morning.

In fact, you may change issues as wanted, which actually got here in helpful once I began working a fever. So as a substitute of getting my aspect chilly as regular, I used to be in a position to pump up the warmth to assist fight the chills — one thing that made being sick only a bit extra tolerable. In much less excessive circumstances, the adjustability additionally means you may tailor your temps relying on the season, as I discovered I favor issues a bit colder in the summertime and a bit hotter in the autumn and winter.

On high of that, Eight Sleep takes its temperature management and sleep monitoring tech a pair steps additional with its Autopilot and Sleep Perception options. Autopilot makes use of knowledge gathered by its sensors to routinely make your mattress hotter or colder as wanted. In my case, after noticing in the summertime I used to be tossing and turning extra typically, it steered a rather cooler temperature schedule, which later resulted in greater sleep scores.

By tracking various metrics including heart rate, the Pod Cover can notify you when you had a particularly good (or bad) night of sleep.

However what is likely to be much more highly effective is Sleep Insights, that are observations based mostly in your metrics that let you know how nicely (or badly) you slept. It is type of like a robo-coach that types via your knowledge to offer suggestions so that you do not have to. Whereas studies typically quantity to notifications about your sleeping coronary heart charge being greater or decrease than regular, I admire that it calls consideration to issues like consuming late or having a drink or two earlier than mattress which may negatively affect your sleep. Annoyingly, each Autopilot and Sleep Perception are locked behind the corporate’s non-compulsory 8+ Professional subscription that prices $19 a month, which is frankly simply an excessive amount of. I do know firms as of late are in search of regular income streams, however these options actually must be free.


In fact, all the flamboyant tech on this planet does not imply a lot if this factor is uncomfortable, and fortunately it isn’t. It is truly fairly the alternative. One in every of my gripes in regards to the unique Pod Cowl is that you may really feel the tubing inside. However on the Pod 3, you may solely inform that it is greater than a dumb mattress topper whenever you contact it together with your palms; laying on it, the tubing is sort of not possible to discern. Admittedly, the topper makes your mattress really feel a contact firmer than it could in any other case, however other than that, it feels rather a lot like a mattress with a skinny foam egg crate pad – simply barely pillowy.


The Pod Cover features a relatively streamlined design, though you will need to find space to position its water hose and spot for the hub.

The factor that made me notice what a big impact the Pod 3 Cowl had on my sleep was how a lot I missed it whereas touring. Even the softest, coziest resort mattress could not make up for the shortage of temperature controls. Different additions just like the Pod Cowl’s upgraded WiFi make the good topper even simpler to establish whereas extra exact sleep monitoring helps you higher determine how nicely you’re sleeping and what you may do to enhance.

The one actual draw back (and it is type of an enormous one) is that with a beginning value of over $2,100, it’s out of the attain of most individuals. And that does not even embody the non-compulsory 8+ Professional subscription, which looks like an pointless tax required to unlock all of its options. That mentioned, even with out Autopilot and Sleep Insights, the Pod 3 Cowl has delivered a few of the perfect sleep I’ve ever had.
