Sleep is paramount to peak performance – both physical and mental
It is essential to get enough sleep, but sleep should also be structured properly and contain enough REM sleep for the recovery of the mind, and DEEP sleep for the recovery of the body. EMFIT QS+ACTIVE records total amount and structure of sleep, the percentages of recuperating REM and DEEP sleep.
EMFIT QS+ACTIVE also records heart rate, breathing rate, and movement activity during the entire night. Overall, it enables you to find sleep affecting patterns and improve them. Results of training or lifestyle changes can be studied with the long-term trends feature.
Ensure you recover enough at night
EMFIT QS+ACTIVE is a powerful and automatic sleep and recovery tracker that will help you take control over your health and wellness, giving you more energy to shine in everything you do.
There’s absolutely nothing to wear and no need to turn equipment on and off. When you go to sleep it automatically starts measuring and in the morning after you leave the bed, the data is available for deep insight from your smartphone, tablet or computer.
Heart-Rate-Variability Shows Your Recovery and Readiness
EMFIT QS+ACTIVE is the world’s most sophisticated ballistocardiograph. With incredible resolution, it records heart contractions, breathing and body movement bio-signals.
EMFIT QS+ACTIVE is the only contact-free health monitor on market that can provide recovery and readiness analysis based on whole night heart-rate-variability. This is why professional athletes, triathlonists, cyclists, football players and other sports enthusiasts have chosen to use EMFIT QS+ACTIVE.
Medical grade under-mattress sensor
The electro-active material itself is self-biased and does not use any power. Only the small electronics placed on the floor uses electricity and has the wireless WI-Fi transceiver. Under-mattress placement ensures longevity for many years use without need to regular replacement.

Setup was super simple. I was able to connect it to WiFi simply by pressing the button on my router, then using a paper clip on the Emfit QS. My sleep info gets sent to the internet automatically and reliably and it is always there in my browser when I wake up. The only problem I had with setup was I have a very thick mattress with no box so I basically had to slice my mattress open and put the sensor in under the mattress pad.
It gives you a lot of information, from which you can piece together how you're sleeping. However, as I found, you cannot rely 100% on the total sleep and sleep stage classification. The accuracy of these numbers is questionable. For instance, my child was lying in my bed reading for 2 hours and apparently not only did he get 1.5 hours sleep, but he got 1/2 hour of REM sleep! Pretty good for being awake!
Having said that, I have reason to believe the toss & turn data is accurate since the sensor for this is pretty basic so you can use this data to clearly figure out when no sleep is happening and do the math to figure out your total sleep. So in order to keep track of my sleep I need to analyze the data, add up the numbers, and keep a separate spreadsheet. Not everybody's willing to do this, but it works for me (so far).
I am planning to buy a Fitbit Alta HR so I can compare results.
The next question people ask is: are the metrics accurate? I also wear an Oura Ring 24/7. It, like the Emfit QS, tracks all the metrics mentioned above. When comparing the results of the two devices, while not matching exactly, show a very clear correlation. They are identical in the sense that when one shows a lower HRV or high HR, the other device has recorded the same trend. Then you have to look at the results provided by the QS and compare it to what you think should be happening, I've found they gel. For example, I was in a bad bike vs car accident in April 2018 that knocked me out of triathlon training for about 5 months while I recovered. During that period the Emfit recorded much high HRV values while recording high resting heart rate values as I lost fitness and aerobic conditioning. Weeks after returning to training, HRV numbers began to drop while my resting HR lowered as well.
I have tried several different sleep trackers and HRV/HR measuring tools. This and my Oura Ring are 1 and 1a on the list of effective devices. If you are looking for a hands-off biohacking/recovery measuring/sleep tracking tool I would highly recommend this.
Let me cover some of the negatives. I had, and others have reported, some connection issues with their home WiFi. I did find it quirky when I first set it up and had difficulty getting it to connect. Once connected though, I have had no drops and there has not been a single night that data was not recorded. Next, there is no option to place it in airplane mode. There is no internal memory to record during the night and then upload the data later. The device it constantly reaching out to your WiFi every six seconds and uploading data while you sleep. For some concerned about having a WiFi signal that close to you every night, this may not be the device for you. Having said that, the Emfit QS does come with a long power cord and a transmitting device that you can place up to six feet from your bed. Nevertheless, a semi-easy update to this device would be a 2.0 model with internal memory that can turns itself off, record your data all night and then turn on and upload the recorded data once you out of bed. Lastly, if you spend a lot of time in your bed, say watching TV or reading before you sleep, the device night confuse it with you attempting to fall asleep unsuccessfully. I read for at least 30 minutes before I turn the lights off. I found that if I just get out of bed to check if the doors are locked after reading, the device recognizes my sleep patterns enough that it does not record the extra time.
A couple of other side notes. I have a Tuff N Needle memory foam mattress. It provides no difficulty in getting any bio-metric signals through it. It also does not pick up my wife's signals when she sleeps, even if we are up against each other.
Overall it has proved to be a solid device that provides good, valid sleep and recovery data.
Update: This device has competition with the Withings (formerly Nokia) sleep tracker which is significantly cheaper. I have both. One advantage of the Emfit device is being able to download data, so you can try your own analysis on the raw data if you're into that sort of thing. Another advantage is being to view data on a browser, so you can use your PC. And Emfit has the capability to show the data being collected at the moment (referred to as "Live Monitor". This is useful as an indication whether my mom is asleep or not and how good of a sleep she is currently getting. With the Withings sleep tracker, you can only see the data after it's been sync'd which I assume is when the sleep period is over. However there are some things annoying about the Emfit device as well. One is that it will only save data if the period is at least 2 hours long. If my mom takes an afternoon nap for 1 1/2 hours, I would like to know about it but Emfit won't save it. There is a "timeline" but without the details of the sleep data being saved for periods less than 2 hours, I have no way of knowing how good of a sleep she got during the nap.
Update 2: We've had the device since June. However I only noticed recently that sometimes (often?) the Live Monitor is not working. I've tried posting on their support portal but it requires approval before putting it up in the forum. After a couple of days, can it still hasn't been approved. I wonder if there support portal is being monitored which questions what kind of support the product receives.
Top international reviews
The comedy of most of these systems is they offer very little understanding of proper sleep requirements, usually relating to deep sleep. You actually require a lot less 'deep' sleep than you might be led to think and people can sometimes get a bit panicky when a device says they'e only had an hour of deep sleep. Your sleep is made up of various 'phases' including deep, REM and light sleep and the actigraphy based devices will simply estimate what phase you were in based on how little or how much you were moving. This is quite unreliable and does not offer meaningful feedback.
The Emfit QS is very easy to set up, the app is only used once on your phone to connect it to your wifi and after that it's a fire-and-forget system. Physically the device sits under your mattress and is slim enough not to cause any worries about it damaging the underside of your mattress or you being able to feel it. I have not had any trouble with the thickess or construction of my mattress which is quite bulky and has a latex topper. The Emfit QS connects to its base transmitter by a long cable, which you are supposed to leave near the edge of your bed so it can guarantee a good wifi signal. Obviously being mains powered it needs a socket nearby to operate.
The beauty of this device is that you literally do not have to do anything at bed time to 'use' it. Nothing. You go to bed, you get up and it does its thing transparently. The Emfit QS automatically transmits your sleep data once it has detected you've left the bed for a preset length of time in the morning. You then go to the website to look at your data. There is no phone app to go with this at all, it is all done through the website. I haven't found this to be any detriment to be honest as the website is very well laid out and offers much greater clarity for reviewing detailed graphing than a phone would. The data is processed around 5 minutes after you leave bed so by the time I've scraped myself together and gone for morning ablutions I can look at my sleep data.
The data itself is quite thorough indeed, a range of graphs and charts are shown to you indicating various things such as heart rate, breathing rate, movements and some more complicated data to do with recovery and ANS (Autonomic Nervous System) The data is well set out and relatively easy to understand and gives your night's sleep an overall score. Trends are easy to analyse on the website where you can look at a whole year's worth of data. I have correlated the heart rate data against other devices and found it to be reasonably accurate for a device that is not actually in contact with your body. I have found that data can get a bit misleading if you are prone to tossing and turning a lot, the heart rate and breathing can sometimes go astray or could lead you to believe you have signs of apnea as the breathing reading often drops quite low in conjunction with a rise in heart rate which is in fact usually just a wonky reading as you move around the device's detection range.
The majority of sleep 'gadgets' simply use actigraphy and maybe heart rate to analyse your sleep, which is in fact a very poor method that produces very misleading results. Seriously, don't even bother looking at your fancy Fitbit sleep data (had three of them; junk), it's not worth a toss I promise you. The Emfit QS uses ballistocardiography which is a more accurate system for estimating your sleep habits and as such does tend to be more useful than most available devices.
However, and this is where it falls down, I also use an EEG based device by a French company called Dreem which naturally gives FAR more accurate readings since it is monitoring brainwave patterns. My form of insomnia can mean that my awakenings are in fact quite short and I quite often forget I even woke up and the Dreem unit pretty much nails these every time. The Emfit QS....does not. In fact, it very rarely EVER knows that I woke up at all and will score me highly for a night's sleep where I woke several times and the Dreem unit scores me much lower since it can see what my brain was doing. The Emfit QS seems to score you very highly for simply being in bed for 8 hours and not moving much while controlling your breathing, all the while you could be staring at the ceiling.
All said and done, I can say that the Emfit QS is a good, if VERY expensive, device for those that want a generally more accurate idea of their sleep health than most wrist based devices offer. If you are looking for something that will track down and monitor specific sleep events/problems, this isn't reliable enough to do that unless like me you're using it alongside other more accurate equipment.
I should state I did not receive the Emfit QS for review so this is an entirely unbiased review.
I've got the WiFi model, which was very easy to set up and can store the data onboard if you, like me, turn WiFi off at night. So, on rising, the information automatically uploads, to then be viewed on your device(s) of choice. Sleeping with a partner does not distort readings either - the tech and installation guidelines deal very effectively with that potential issue.
If you don't know about HRV, then you should. It's probably one, if not the most important metric we should all be taking notice of in this instant gratification mindset (modern life) we all get sucked into.
I am so impressed, I've bought another, for my partner.
Haven't yet tried using another WiFi network or my phone hotspot, but I've only had it a week.
The tech support is second to none - 3 cheers to Heikki!
I tried this and initially thought it was working, but then realized the heart rate detection was erratic and the breathing rate monitoring wasn't even there.
I then tried laying directly on the sensor and the HR data was accurate and the breathing rate appeared on my phone screen.
I am still deciding whether to return it for refund or purchase a mattress topper to place it under. It may well work properly if you have a foam mattress or just a really thin sprung mattress.
It's a pain to set up (will probably vary based on network provider/ router firmware) but got there in the end and now it connects within a minute every time I turn it on.
The reason I purchased this is I am a keen cyclist of 12K miles a year and regularly riding 100+ miles, and wanted to understand more about how I am sleeping and how my body has recovered during training (trying to prevent over training) as well as pre and post event recovery.
Für die Auswertungen der Daten gibt es keine App, sondern ausschließlich eine Website. Die passt sich aber den Smartphone- und Tablet-Formaten an, so dass man gut damit zurechtkommen kann.
Zu den einzelnen Auswertungen gibt es kurze Erklärungen, die aber nicht immer umfassend genug sind. Z.B. gibt es in Grafiken oft Balkenfarben, die keine Legende haben und deren Bedeutung man nur erraten kann.
Das große Problem ist die nächtliche Datensammlung - die hat bisher so gut wie nie funktioniert. In fast allen Nächten brach die Aufzeichnung entweder irgendwann ab (z.B. letzte Nacht ab 03:08 keine Daten mehr, warum auch immer), oder bei nächtlichen Unterbrechungen von zwei- bis drei Minuten wurde zwar das Verlassen des Betts, aber die Rückkehr in dasselbe entweder garnicht oder erst viel später erkannt. Das führt nun dazu, dass die Gesamtzeit im Bett und die Gesamtschlafzeit nicht stimmen, und damit dann fast alle Auswertungen unbrauchbar sind.
Ich habe das mit verschiedenen Positionen unter der (übrigens ganz normalen) Matratze probiert, ohne nachhaltigen Erfolg.
Der Support hat anfangs freundlich und blitzschnell geantwortet. Eine Aussage war, dass es bei einer Gerätecharge zu vielen Reklamationen kam, und man deshalb versuche, dies über Änderung der Sensitivität nachzujustieren - und dass mein Gerät aber nicht davon betroffen sei. Seit einigen Tagen, in denen ich nun noch Fehlerberichte und Screenshots an den Support sende, kommt leider keinerlei Antwort mehr.
Die Idee verdient eine bessere Bewertung, finde ich. Nun hilft aber die interessanteste Auswertung nichts, wenn Daten fehlen - und wenn der Support dann nicht einmal mehr Lösungsvorschläge aufzeigt, ist das Gerät für mich nicht verwendbar. Leider!
The only thing missing is any way to overlay this with sports data from another provider (personally would like to see google fit) Without this integration it's difficult to action the data provided
