## Description

Product Description        Emfit QS recovery, stress and sleep quality monitor's key feature is to track changes in user's heart-rate-variability (HRV) after each training day. Being able to analyze this important data helps user to prepare for next training day. Emfit QS helps maximize fitness potential by tracking not only HRV, but also recuperating REM and deep sleep. No more guessing when it's the right time to push yourself to the limit. The Key to Winning! The key to high-level performance and the way to the podium is often the quality and amount of sleep athletes get. Sleep is when the real training effect takes place. Sleep repairs, strengthens, and rebuilds muscles. Particularly REM and deep sleep provide energy to the brain and body. Why Heart-Rate-Variability? How do you know when to train and when you should take it easy? The answer is heart rate variability. HRV will give you a picture of your overall health, but also helps you optimize your training and maximize results. HRV can also reflect changes in stress when other physiological parameters, like blood pressure, are still in normal ranges. Non-Contact and Automatic Emfit QS offers continuous non-contact vitals measurement. There's no need to wear a straining chest band or strap anything on your wrist, and no need to remember to turn equipment on and off. Just lay down on your bed and go to sleep, and wake up in the morning well rested, relaxed and happy. Check out your sleep data, as it will be freshly at your disposal on our mobile optimized web app. Emfit QS is a powerful, non-contact sleep monitoring system which is unobtrusively installed under your mattress. It is accompanied by an intuitive web app that provides comprehensive reports about your physical recovery, stress levels, and sleep quality. Emfit QS product and web application is not a medical device and is not intended to be used for diagnosis or monitoring of disease or other conditions, or investigation of a physiological process.          Manufacturer's Description         Get complete insight to your sleep It’s essential to know the condition of your body each and every day so you can optimise your training and recovery, and achieve maximum long term results. With Emfit QS you get a complete breakdown of your sleep and cardiopulmonary body functions automatically from every night, without having to attach anything to your body. Why heart-rate-variability (HRV)? The key feature of Emfit QS is to track user’s heart-rate-variability (HRV) over entire night. After a heavy training day you can expect to see a clear rising trend at our entire night HRV data visualization. This tells you two things: first that you have been training hard enough and secondly, that you have fully recovered during the night. If you haven't been training you can expect to see a horizontal line. Downwards trend indicates stress or there might be something wrong physically. Embedded Wi-Fi - no phone needed Embedded Wi-Fi connection ensures its autonomous operation. Operation is all automatic without need to remember start/stop measurement.  Under mattress installation Emfit’s proprietary sensor is discreetly installed under the mattress. It is flexible and convenient yet designed and build using materials ensuring its long lasting operation. Warranty period is two years. Mobile optimised web application User’s sleep data is accessible over web application that is also mobile optimised. Amazingly rich data makes Emfit QS a perfect fit for athletes and fitness enthusiasts and anyone interested in their personal health and wellbeing. Avoid overtraining Overtraining is a very real threat to many athletes. It can easily ruin one's entire season, so it must be avoided! Checking on long term trends is crucial because they show what values are going wrong. Emfit QS long term trends are most detailed on market having 6 different insight pages of important data attributes. About the Startup Describe your product in 3 words.Ingenious, insightful, irreplaceableHow did you come up with the idea for this product?We wanted to solve the problem of keeping track of health, recovery and sleep in the simplest way possible without having to wear anything. We had already been doing vitals measurement from under the mattress for years, and health along with quantified self has been a rising trend, so creating a recovery and sleep monitor was just the right step for us.What makes your product special?First, it is our proprietary sensor technology. Even though we developed it already over 20 years ago, it is the newest on the market for dynamic ballistocardiogram measurement. Where competition uses piezoelectric technologies that are over 40 and even 100 years old, our sensor material produces ballistocardiogram signal with sensitivity and quality, which are the richest details about cardiopulmonary functions. This is why scientists have been excited to do and publish over 200 scientific articles using our sensor technology for various cardiopulmonary functions researches. Secondly, it is our product philosophy. We started to manufacture contact free ballistocardiogram sensors 15 years ago. As a true pioneer in this field, our experience from customers is need for durable but completely discreet solution that is totally autonomic in its operation. This became our mission and our electronics and software platform is developed accordingly. This is why we use Wi-Fi instead of Bluetooth; so there is no need for having a phone for measurement. This is why we developed our product to go under the mattress and have sturdy cabling, medical quality power supply and so on. What has been the best part of your startup experience?Emfit QS is our internal start-up. 15 years ago we were at ground zero and started pivoting our company from a sensor material manufacturer into an innovative and disruptive health care technology provider. It surely has taken all our team's energy and resources during all these years. It has been very exiting to work and collaborate with many health care professionals, get deep into customers problems, and say, living on the edge. We must thank our first customer groups, which are people with epilepsy and elders, for our existence. Working for tens of thousands of families and care institutions has been extremely rewarding. Meeting families. To get all the customer feedback and feel that we have been needed and there is meaning for what we do. Now we are trying to expand our experience into helping athletes and general consumers. Sleep is after all of greatest importance to us all.

## Questions & Answers

**Q: Does this work for 2 people in bed and track each side independently**
A: no, just one person on one side of the bed

**Q: Will this work with a Sleep Number bed?**
A: Yes definitely.  I am using a sleep number bed now.  I tried the belt two ways, under the mattress and on top of it, but under the mattress pad.  It’s more sensitive to movement on top of the mattress.  That’s my preferred mode.  Buts it’s equally sensitive to all the other metrics in either location.     Rich S.

**Q: My dog sometimes sleeps on my bed, will it throw off the data?**
A: No, it won't.

**Q: Increasing medical studies recommend naps for memory & recovery. Does this track naps?**
A: It can be set up to track or ignore naps.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A great investment
  

*by A***R on Reviewed in the United Kingdom on 19 April 2018*

This device is fantastic. As a bioengineer and personal trainer, I love how much information it provides and that it also gives the option to provide the raw data. I'm not an elite athlete or anything, but it allows me to identify problems with my sleep and identify when stress or training is taking its toll. If only more people were aware of the importance of sleep, and how duration does not necessarily equate to quality, I bet we'd live in a much more productive society.Issues: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.

    Beware import duties!
  

*by M***S on Reviewed in the United Kingdom on 19 November 2021*

This is shipped from Germany so post-Brexit will be impounded by customs on pain of an extra 20% VAT+admin fee.This should be reflected in the price (assume you are currently expected to pay VAT in Germany as well as the UK ) and potential customers buying on Amazon's UK site should be informed of customs fees.Amazon will also not help you out if you parcel is stuck in customs as this is a marketplace item.For this reason do not buy this product unless you are willing to add another £70 to the listed cost (currently £256.24 + £13.40 delivery as of 19/11/21).

    Better than wrist based devices, but not perfect by any means
  

*by A***S on Reviewed in the United Kingdom on 20 October 2018*

I should start this review by stating that I am a long time sufferer of maintenance insomnia (able to get to sleep easily but cannot stay asleep for more than an hour at a time) I have used many, MANY devices and gadgets over the years to get a better picture and understanding of my sleep habits. I've used wrist based devices, finger mounted trackers, bedside trackers, Sleep As Android etc etc. In fact, I've spent a hilarious amount of money over the years it's not even funny.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.
