THE EIGHT SLEEP POD PRO COVER
(started Feb 1, 2021 and updating every day until trial expires or I get fed up - Feb 13, 2021)
There are plenty of useless reviews around the internet regarding the Eight Sleep technology that have nothing to do with whether or not the Eight Sleep technology does what it claims. These reviews tend to focus solely on the mattress comfort. They are reviewed by people who admit to having no insomnia problems - is it odd to anyone else that these perfect sleepers have this job? I am a firefighter, so I sleep in random, "cost-effective" beds on a regular basis. I have also owned some nice mattresses and have slept on some very nice mattresses of ex-girlfriends. Not one of those beds has ever improved or worsened my overall sleep quality. I will admit, they can feel better and affect my body soreness, but not my sleep. My point is, those reviews rate the Eight Sleep mattress purely on the reviewer's specific personal comfort needs (or what they beleive others might like), not the Pod Pro Cover which is the key element and a very unique technology designed to use a crowd-sourced algorithm to improve sleep for everyone. I will bet money that no one is paying the price of an Eight Sleep Pod just so they can get the mattress. If you want to skip to my thoughts on the function of the Eight Sleep unit, skip about halfway down to "TRIAL RESULTS" to review my running journal of the bed's inaccuracies. Or skip to the very bottom to read why this bed doesn't do for insomniacs what it claims.
My Story and Sleep Issues:
* After a week into my Eight Sleep Trial (Feb 6, 2021), I considered that I may have an overactive bladder (OAB) or enlarged prostate. My PSA blood work indicates no problems with my prostate. Though I have not had a digital exam, I believe I get an ultrasound of it yearly through my job physical. I did some research and one study believes that bladder issues to be common following hip fracture. Coincidence? I will add noctuia remedies in "What I've Tried" below.
My current station assignment (assigned June 2020) provides me with a call-free night many more times than not. However, the past eight months there have not helped to break the awful cycle so that I may sleep straight through to morning. I tend to wake 30-60mins before my alarm, and once I am up between 5am and 7am, there's little chance of going back to sleep. Sleeping-in just hasn't been an option for many years for me. If I am lucky, I will get five total hours of disjointed sleep. I have noticed that when I am waking frequently (which, for me, is two to five times every night), I usually wake with the immediate and strong urge to urinate - I sometimes wonder if this is a trigger that wakes me. On the rare occasion when I sleep through the night (one to two times a year; six hours uninterrupted), I will wake with minimal urge to urinate and be able to lie in bed for awhile before feeling like I have to go. The day after those good nights, I feel amazing and I feel like my old self. The bathroom needs tell me that my body is not properly resting and that my kidneys are running as if I was awake. I assume that all of my organs are doing the same, like ticking up excessive mileage on a leased car.
I'm a light sleeper. This is very problematic for someone sleeping in an environment with multiple persons that may not be on the same sleep schedule, not as courteous, and may be responding to other fire or EMS calls. If I wasn't such a light sleeper, I think I'd have little problem resolving this. For that reason, I use a sound machine and earplugs at home and work, which do help greatly. However, my body (and brain) still wakes itself up at home, with no outside interference.
I have a feeling that cortisol is also playing a role in my problem. Cortisol is a stress hormone that aids in fight-or-flight, or a "survival hormone." My body has become so adjusted to the perceived need to be awake all the time, despite my lack of quality sleep, that it may be dumping more cortisol than the average person, and doing it at the wrong times of the day. I'd wager that anyone that is a light sleeper with insomnia has the same issue as I do: even though we're worn out and not aware of any mental stress that might keep us up, we are unable to nap for more than five minutes. I used to sleep-in and nap like a champ when I was thirty years old. Being in a different sleep environment may also be causing me minor stress due to the body's desire for sleep consistency and routine. Once cortisol secretion is out of sync with our circadian rhythm (the body's internal clock that makes us awake during the day while also inducing sleep after sunset), it can cause a negative feedback loop where lack of sleep causes more lack of sleep.
My body seems to have developed a temperature regulation problem. This was not the case in my younger years when I would barely sweat - my body was able to regulate itself easily. It seems, that not long after I first started having sleep issues, I would sweat more profusely. This became noticeable between 2012 and 2014. There are times now when I look drenched under minor exertion. I believe this has to due with my blood vessels losing their ability to dilate properly and allow my body to release heat. This may be caused from loss of elasticity in my blood vessels*, which could be a result from my lack of reparative deep sleep. I slowly developed mild hypertension (high blood pressure) in the past few years, which adds some merit to my idea that poor sleep causes arterial hardening. I have noticed that a lot of the times when I wake up at night, I am feeling too warm, or even sweating - my body is not letting off the heat as well as it should. Science tells us that lower body temperature is more conducive to our deep sleep cycle. Lowering the ambient temperature doesn't always work when we like to sleep under heavy blankets, next to someone, or on a foam or low-quality mattress. This is another negative feedback loop where lack of sleep causes more lack of sleep. Manipulating core body temperature to promote more effiecient sleep cycles and reduce awakenings is the key area that the Eight Sleep algorithm claims to focuses on.
* Arteriosclerosis is generally blamed on old age. But data has shown this is worsened by "cholesterol issues." We must remember that cholesterol problems are actually caused by sugar interfering with the way cholesterol functions in the body. I gave up sugar and simple carbohydrates at least three years ago, and my cholesterol numbers are exemplary, so this eliminates sugar consumption as the cause of my supposed arteriosclerosis.
Beta-amyloid/Amyloid beta. Studies for Alzheimer's have discovered that the build up of this protein may be the root cause of the disease. Throughout our nightly slow-wave sleep cycles, this waste product is flushed from our brain by cerebral spinal fluid. If our sleep is interrupted, the flush fails to occur completely and the amyloid beta builds up to eventually form plaque. This plaque damages and destroys neural connections in our brain, making it difficult to form, retain, and access memories. It also may attribute to irritability. I have always had short and long term memory issues (my mother recently told me that I had sleep problems when I was young), as well as irritability in the last few years. Unfortunately, this also seems to be a very dangerous negative feedback loop: the more plaque you build up, the more difficult getting the proper sleep needed to flush these amyloids away becomes. It has yet to be determined if this built-up plaque can be flushed away once it has formed. However, one study that I read suggested that the brain can build new neural pathways around the damage - this was theorized to occur most rapidly in the elderly subjects that never stopped learning new subjects or skills.
Some people only need five to six hours of sleep. False. Try telling that to an Olympic coach. Studies have shown that this is not really feasible for good health. Our sleep is divided up into stages of sleep (a transition stage from awake, light, deep, and REM) and our body cycles through them several times a night. Each cycle lasts 70-120mins and any interruptions obviously disrupt the order of the stages. Optimally, the goal is two hours of deep sleep plus two hours of REM sleep, which is not easy even for a person sleeping nine hours. Those two sleep stages together can average thirty minutes per cycle, so a person would need four cycles to reach that goal. My math says that if the subject slept six hours straight, they'd get 360mins of sleep. If the average cycle takes ninety minutes to complete, this person would require the full 360mins - they better be the most efficient sleeper on the planet. Note that this is just my rudimentary way to show that people need more sleep than they might think ...odd that these great sleepers tend to drink coffee and Red Bull. The body has mechanisms to help people make it through a day after inferior sleep and give them a false sense that they are fine. I function very, very well for someone that hasn't slept decently in ten years because I am used to it, but I know and feel that this is not healthy.
Sleep can be banked, or made-up over the weekend. True and false. Read more on the subject of beta-amyloids to understand why this theory is problematic. You may be able to physically recoup by sleeping-in over the weekend, but there might be damage occurring during the week that you may not notice until decades later.
Food is more important than sleep. False. You will die of total lack of sleep before you die of starvation. Even if you think you've been up for 48hrs, your mind is taking "micro-naps" that may last mere seconds, which you won't even notice. This is just enough time for it to extend the clock. If you were forced to stay completely awake, the last thing you will likely be concerned about is your caloric intake.
What I've Tried:
Adderall (non-XR): to me, this is a miracle drug for those that feel tired during the day. As I mentioned, lack of sleep can cause me to be irritable and also give me a headache that lasts all day. Taking 10mg of this first thing in the morning after a terrible night of sleep will have me smiling and whistling while I clean the station toilets. Co-workers could tell when I didn't "take my meth today" as I feel close to my old self while on it. I would only take it first thing in the morning before a shift (and not every shift) to prevent it from negatively impacting sleep that night. This med is the only reason I didn't get fired, or outright quit, when I worked at a hell station for one year. Since the station transfer, I might use it once every four to six months.
TRT: I had my first testosterone blood work in 2013, at the age of 37yo. I do not know what my base line was, but at that time, my testosterone was 315ng/dl. Dependant on age and health, testosterone should range between 250-900ng/dl. I believe the lower end of the scale is skewed down due to the general unhealthiness of most American males today. At 37yo and despite my low result, I was in great shape, lean and muscular, quick and strong with high endurance. But I would feel sore for days, especially after very grueling leg days. I high-dosed Cypionate and hCG in early 2014 to improve my levels. For three months, my testosterone levels were between 2500-2700ng/dl, while also taking Arimidex to keep my estradial low. Now any doctor will tell you that high testosterone with low estrogen will do the following: improve mood, improve workouts, improve gains via lean mass, help maintain muscle mass, improve erections, and improve sleep. The only benefit I got was muscle recovery, so I would finish workouts psyched to do another the next day without being sore. I easily gained ten pounds of lean muscle, but my sleep never improved one bit and neither did my dreary demeanor from the continued lack of sleep. I currently like to hover around 900ng/dl and the only benefit I have is maintaining lean mass longer than without it.
I stopped taking my TRT (Cypionate and hCG) on January 24th. Why? I don't know, I just didn't feel like taking it anymore. I've been distracted with other things (like sleep), so I've been lazy with it. Due to my stricter bed times, with the help of the new blue/green blockers, I think I'm sleeping more (not better). I have felt my sleep is the root of my low testosterone, so I'm curious if my consistent bedtimes might be helping this issue. I have a physical coming up and am curious where my levels will be.
Blue blockers: this works to some degree, especially in helping me get to sleep quicker. I am currently using Sleep Savior blue/green blockers with red lenses ($60). The theory is that the blue spectrum (from the Sun) induces wakefullness - this helps set our circadian rhythm, which in turn, helps to release melatonin at the proper time. Wearing these lenses after sundown in the house helps to prevent the body's internal clock from being confused by harsh lighting, televisions, and cellphones. Be aware that, even though they are marketed as blue blockers, the clear lenses are for computer eye strain and the orange UV lenses do not block the entirety of the necessary spectrum. I also have The Sleep Aid Red LED night light ($18 for two) that I use in the bathroom that gives me enough light to wash my face, brush my teeth, and remove my contacts without wearing the red lenses. These are
Home apnea study and lab EEG: I am negative for sleep apnea (though my exes have said differently on occasion, but that might just be my neck posture that night) and microseizures. I do have nights where my co-workers say I snore, but it doesn't seem to be on a regular basis and I never wake myself up from it.
Dropping the room temperature: this seems to work a little, when the ambient temperature is 65-68*F. It is problematic though because I've been woken up too cold or still continue to overheat. Time of year, being under covers, or near a partner, can make ambient temperature a problematic variable. This is where the Eight Sleep algorithm claims to come into play, using your biometrics to adjust your core body temperature to promote proper sleep cycles and reduce awakenings.
THC and CBD: I was straight edge growing up, so first tried marijuana at 42yo to help me sleep. CBD seems to do nothing except dry my sinuses out - if anything, it may help calm people with racing minds. Though I do have racing thoughts a lot of times, I have not noticed a difference with CBD (blue blockers seem to work better). THC just causes me to be disoriented and stumble trying to stay upright while I piss several times a night. It likely disrupts sleep cycles. However, it induces mind-blowing sex.
Alcohol: I have never purposely tried to sleep better through drinking. It may help calm thoughts to fall asleep, but it simply doesn't work to improve restful sleep since it will negatively alter your sleep cycles. Also, I rarely drink alcohol as I only do so socially. If by chance I do, I will make note of it in my sleep log for that night.
Fiber: To stifle my nocturia, I started taking fiber before bed again as I had tried in 2010 by eating a bagel before bed. Well, I don't recall how well this worked back then and I no longer eat bagels. I initially started taking 1.5gram of psyllium husk caplets nightly, a couple weeks before my bed arrived. It seemed to only work the first few nights, so I tried doses of eight to ten grams via psyllium husk powder. The problem is that it needs to be mixed with water, which is counterproductive. I started noting the dosages in my trial diary below, on February 6, 2021. Fiber is something I am always conscious of, so it is unlikely that I am not getting enough fiber throughout my day.
Bladder health: relating to my nocturia and possible overactive bladder, I have tried short programs of Kegel exercises before, but I am now reading that results could take three to six months! Kegels seem to be important to everyone and I have female friends that are experiencing issues in their late thirties because these muscles seem to simply lose their tone over time, even in those that exercise regularly. Although I do not experience incontinence or flow issues, I will try to stick to a regiment of at least three sets a day and doing ten reps (one strategy is to do them while brushing teeth). I will also keep a journal to measure fluid intake, output, and frequency. A healthy bladder produces 800 to 2000milliliters per day with a normal intake of half a gallon. That's a pretty broad range, but a healthy bladder's capacity in an adult is normally 300 to 400ml. I try to drink 96ounces of water every day, so I should expect to excrete 1200 to 3000ml a day. This will likely be on the higher side on more sedentary days. That means that I should expect to urinate no more than ten times in 24hrs. That sounds like a lot, but there are times I will use the bathroom several times an hour if I am trying to drink a gallon in a day, so I will definitely be measuring output to gauge capacity. I did this back in 2010, and if I remember it correctly, I was able to occasionally hold 500ml. But I know there are times when a single output seems to be relatively much less than the urgency feeling. So here's the real question the journal should answer: is my insomnia causing my overactive bladder, or is my overactive bladder causing my insomnia?
My New Bed:
I've seen some forum reviews complaining that the Oura Ring is much more accurate than the Pod Pro Cover (PPC), while others say their data is almost identical. I always assume most people lack common sense, so my initial assumption is that the bed was not set up properly. And by that I mean, the coverings or fitted sheets that they placed on top of the PPC were likely loose or too thick, therefore interfering with the sensors' abilities to do their job properly. Initially, I only put a mattress protector over the mattress to protect it from leaks. I chose the COHOME Protector ($34 each, for king) because the pocket on it fits on the shallower side, reducing the possibility of bunching on my 11" T&N. Once I had installed the PPC, I decided to add a second one on top of that to prevent dander and mites getting into the grid area which cannot be cleaned. These covers a thin and fit rather tight, which should allow the PPC more accurate readings. For sheets, I chose Threadmill Home 100% ELS Cotton Sheets ($70 for king) which fit up to a 16" deep mattress, so there wouldn't be a lot of bunching. To allow the sensors to work best, I figure a tightly fitted sheet is optimal, so added Dericeedic Sheet Straps ($12 for four). I do not have pets and will be diligent in making my bed every morning to protect it from the few mishaps I have read about online: poking holes in the PPC bladder. My twenty-five pound ZZZhen Wieghted Blanket that I bought for my california king ($125 in 2019; 80"x87") fit on my new king bed very well.
Note: I will be referring to the sides of the bed as the Eight Sleep does, where you are looking at the bed from the foot of the bed.
The Eight Sleep Pod Pro Cover:
* After a few nights on the bed, I am realizing that the Active Grid takes away from the comfort of my Tuft & Needle Original. The mattress is no longer able to "envelop" around me, so it makes it feel firmer than it is. This is especially evident when I occasionally sleep on my side and wake to shoulder joint aches. Maybe the Mint would be a better choice, but it still won't "hug" like foam with the Pod over it. Then still, if you buy a softer mattress to help this, then return the Pod, you might now be stuck with too soft of a mattress. This could cause all sorts of long term issues and/or wasted money. Maybe the best option here would be to use your current mattress or buy the Eight Sleep mattress so you can return the whole thing, and then you could buy something else?
The priming directions are a bit confusing as well. The app kind of leads you through the process. For my king, I ended up using 1.5gallons of distilled water with 1/8cup of hydrogen peroxide. After filling the tank with water, I initiated the first priming phase. About 10mins later, the unit stopped making noise and the tank was near empty: this was the end of the first phase. Confused, I refilled the tank and tried to figure out what to do next. That's when I got the delayed notification that the first phase was over, then I figured out that it was now time to move on to the "temperature phase" of the setup, for some reason. I believe the temperatures are set relative to ambient (apparently they are not, but this isn't detailed anywhere), so you choose +/- the degrees you want the bed to be relative to the room. Right now, it's basically a guessing game. Once you set up these very basic parameters, it then instructs you to begin the second priming phases. The app told me this would take up to ninety minutes and I could walk away. However, it took at least two hours and I had to monitor the water level, filling it a few times (I just kept the lid loose and added while it ran).
Mattress rotating/flipping: Tuft & Needle recommends that owners rotate their mattresses every six months. This will require the enitre Eight Sleep system to be removed and remounted.
Notes: I work for the fire department, so I am at the station for 24hrs, every third day and sleep there overnight. My times will be in the military format (ex: 2245 = 10:45pm). Eight Sleep recommends consistency for quality sleep, so I will be trying to be in bed by 2200 and set my alarm around 0630. Below each "Night #" I will list the four in-app temperature parameters that I set for that night. The ambient temperature (Fahrenhiet) and humidity level (percentage) will be at the time of me getting into bed, and according to the Hub unit. I sleep on the right side of the bed and am currently single, so no partner influence on data. While checking on some information, I noted that Eight Sleep claims that members experience 13% fewer wake-ups. Seriously?! That means if I normally wake five times a night, I will only wake four and half times, now? I hope this is a global average that includes perfect sleepers, that never had this issue, skewing the average way down.
*** SLEEP LOG ***
Night 1 (Jan 27 - Jan 28, 2021):
Note: The app recommends setting the bedroom's ambient temperature between 60*F and 70*F. It says this is what studies have shown to be optimal for sleep, and I am aware of this. However, none of the studies that I've read were using a cooling mattress. I will try to keep the house around the 68*F to 70*F mark because I feel the PPC should be doing most of the work.
Night 2 (Jan 28 - Jan 29, 2021):
Regarding HRV (Heart Rate Variability), the app makes no attempt to explain what my numbers indicate other than it telling me I can do a “typical” day of physical and mental activity (whatever “typical” means), nor does it tell me what number I am trying to achieve or how to do so. There is a “Discovery” article link on the app that assists a little. Apparently, as the algorithm measures my trends, it will have a better reference of my goal and make suggestions (like the Sleep Fitness info suggests). However, there is no information regarding when this might occur, which is another issue I have with this system: most features are vague. Referencing the Whoop site’s stats of its users, my HRV of 64-65ms is at the male average of 64ms while the average for my age group is 48ms. According to their site, as we age, our optimal HRV normally decreases. A higher HRV usually indicates being more healthy, but we should track trends since optimal HRV can vary greatly among individuals, with some elite athletes having an HRV below the norm.
Night 3 (Station HR42):
Night 4 (Jan 30 - Jan 31, 2021):
This all got me thinking: this bed is great for people that sleep through the night. However, what about those of us with not-perfect sleep, which this bed is very heavily marketed to? How am I supposed to take advantage of the temperature if the bed is only smart enough to run one series of temperatures in eight hours? I would think that someone like me would need the series to automatically adjust a little for when I wake up so I'm not trying to fall back asleep while feeling too cold (which has happened twice) or too hot? Which begs another question: when exactly does the Final temperature go into effect? Furthermore, the app implies that the overnight temps should influence my choice for the app's temperature settings, which are already difficult enough even without the weather's fluctuating temperatures. This has me wondering why the Active Grid doesn't instead have a sensor to detect body heat and then make adjustments according to that metric for more consistency, greater accuracy, and less user error? It's very vague, but their site implies that there is a body heat sensor. So, are my settings relative to body or ambient temperatures? And if it is body, then why does outdoor temps matter? I think I will be calling Eight Sleep sometime this coming week to voice my concerns, plus request a longer trial period since I am a first responder and away from this bed every three nights. At the moment, this thing is destined for a return and refund. A friend of mine brought this to my attention: Eight Sleep claims that the bed will help those of us with sleep issues. Now, not only is the unit failing to improve my sleep, but the data and app are implying that am getting good sleep. Total failure.
Note: from now on, I will date these like the Eight Sleep app, which stamps them according to the morning I wake up.
Night 5 (Feb 1, 2021):
Every morning, the app asks how accurate the Sleep Stages chart looks, and every morning I tell them how inaccurate the results are in detail. Not one person in the company has reached out to me about these issues. So, I decided to send an email to email@example.com (Jan 31 at 4:17pm) requesting a user manual because the whole temperature choosing system is vague. I also commented on the poor Time Slept calculations and the HRV contradiction.
Night 6 (Station HR42):
Looking through the Eight Sleep site's reviews today (all being incredibly positive), I am noticing a trend: most of these are from couples who are using the bed to solve the "I run hot, she runs cold" dilemma. Ugh. Not a lot of mentioning of sleep quality. Saving marriages should be Eight's marketing focus, rather than leading us to believe that the bed can improve sleep.
Night 7 (Feb 3, 2021):
Yesterday, I sent another email (Tues. Feb 2 @ 11:53am) to Eight's customer service advising them that I was reviewing the unit and asking them to take a look at this webpage, then let me know if my unit is malfunctioning since it was failing to do what their site claims. I got the auto-reply saying most emails will be answered within 12hours. So far (Wed. twenty hours, at this entry), there has been no response. Nor have I gotten a timely response back from my reply to Saidy (the same email address; 48hrs since I sent it) asking her to make sense of the Time Slept miscalculations and to clarify the importance of outside temperatures within a climate controlled house.
Eight still doesn't seem interested in my problems, so I will [harrass] them by phone another day. I am not fond how these bed covers can negatively impact my otherwise comfortable mattress, but chiliSleep makes a weighted blanket. Unfortunately, they only offer them in 45"x80" with a single temperature zone. I emailed chiliSleep today about their blanket, purely for comfort during the warm summers in Florida. I asked if they had plans for a dual-zone king blanket, which could use two chiliPAD or two OOLER units. Waiting on a response. I know BedJet makes a dual-zone sheet, but I'm looking for a weighted blanket. I'm also not sold on the BedJet's tech due to sheet bunching possibly preventing airflow, especially at the price they are asking for them.
I just want to add that I made the decision to try the Eight Sleep based on this interview with the CEO of Eight Sleep (Matteo Franceshetti), this video review, and this page that outlines the "sleep fitness technology" that is supposed to make you sleep better. I used this link to get $250 off the cover.
Night 8 (Feb 4, 2021):
Night 9 (Station HR42)
This morning, I woke to an email from Eight's Saidy that arrived at 0200 overnight. She apologized for the delayed response and said she "would be happy to have my case reviewed by the Engineering team to make sure the sensors were working as intended." She requested that I give the team permission to access the device remotely. I replied with a thank you at 1120 (Feb 5), and gave them typed permission to review my data.
I also got a reply from chiliSleep saying they only had the one chiliBlanket size, but would forward my idea to management. I have to assume that someone in the company has already thought of this, so I will take the possibilty of a soon-to-be-released dual-zone king chiliBlanket as "extremely unlikely."
Night 10 (Feb 6, 2021):
Follow-up email from Saidy stating that the engineers were running tests and she will check-in within the next few days. She said to contact her with any other questions or concerns in the meantime.
Feb 13, 20121: On Feb 7, I realized I needed to replace my Grand Cherokee, so I have been distracted with that and my sleep schedule has been affected from staying up late to research vehicle options. I was already in a downward spiral for Time Slept, and this kept that going. At this point, I stopped bothering to use the Wake Up feature of the Eight. Also, I may have slept wrong and started to experience neck and shoulder pain that has continued throughout the week - I may need adjusted. I am six days behind in this diary...
Night 11 (Feb 7, 2021)
Night 12 (Station HR42)
Night 13 (Feb 9, 2021)
Saidy from Eight Sleep contacted me the evening of February 9 to let me know that engineering needs feedback in the app regarding the data accuracy. I didn't bother to email her back for two reasons. One being I had my mind on other things and the other being that I have been doing this since day one. They should be able to figure it out from the old data. In any case, I did. But that has me thinking: what are they doing on their end? Either the sensors work or they do not. Unless, they are going to tweak my sensors ...and that has me wondering why and how? Why doesn't this thing come properly adjusted? How many people are using it with poorly set sensors? In any case, the bed seemed to become more accurate in the following days (still not close to perfect). However, this did nothing to improve my sleep and was only able to prove how accurate my own calculations were for the previous two weeks.
Night 14 (Feb 10, 2021)
Today is February 13, 2012 and I had planned to continue to log the remainder of the week (and finish out the two remaining weeks of my trial). But after that last paragraph, I really don't see the point. The bed is a failure. Granted, my bed is cool, but that alone has not helped to change my sleep in any way. It actually may have hurt it because in my naivety, I was setting it too cold (because I was led to believe this is what I needed from their website) and this caused me to have difficulty returning to sleep. Maybe a person that doesn't have broken sleep can benefit from this bed, but that doesn't seem to work in my situation. Furthermore, the bed has done nothing insightful to guide me to better sleep ...certainly nothing I didn't already know from years of battling with sleep-maintenance insomnia. Plus, I think I would be happier sleeping directly on my comfortable mattress without the firming interference of the Eight Sleep Pro Pod Cover.
