Withings Sleep - Sleep Tracking Pad Under The Mattress With Sleep Cycle Analysis

I really want to like this product, it is simple to set up, the initial sync with the phone and app works the first time, the software updates are trouble-free, but initially, the sleep tracking failed. I had it for a week and it successfully tracked a full night’s sleep only twice and failed to track any sleep once. It most often tracked about 3 hours of sleep. I suspect that the device is also timing out, and failing to recognize that a trip to the bathroom or to get a glass of water is not the end of a night’s sleep and is failing to link the remainder of the night or tossing out the initial period and crediting the second and longer period. Edited 5/23/2018 Product support suggested a lower and more centered position. This did not resolve the issue until I reset the pad and recalibrated. The pad is now positioned about sternum level and seven inches from the side of the bed. (queen size bed occupied by two, so centering is not an option) It now appears to be starting and stopping with my observed sleep periods. If you are diligent you can get the pad to record correctly. Most likely you will need to position the pad lower than implied in the instructions and six to ten inches in from the edge of the bed. Edited 10/6/2018 Five months later and I still really like the pad. Consistent tracking every night, and periods out of bed long enough to make a cup of chamomile tea are included in the same night's sleep period. Edited 8/5/2019 We added a second pad for the opposite side of the bed. Both pads record distinct sleep patterns for both occupants of the bed. Obviously, I have remained happy with the performance.

Not sure how to judge this without doing a comparative test with other systems, which I have not. On its own it seems to be working well and providing feedback on my sleeping patterns, which is why I bought it. Tells you how often you are in light, medium or deep sleep, or if you are "awake" - each of which is helpful I guess to judge the quality of your sleep. It gives an overall score for your sleep each night, which is a decent way to judge your overall quality of sleep. It also tracks snoring and heart rate, which are also good to know. I don't like the fact that it may be listening to me at night, which is how it tracks the snoring, but they promise that recordings are not stored! For my own privacy I hope that is true!!! Wish I could turn that part on or off, and that I could get access to those recordings to hear what they sound like and to ensure they are deleted on their system - as I think they are stored on a cloud somewhere. That part is scary to think about, but I am taking their word that they delete it. I also don't like that if you lie in bed and watch TV before bed it counts that as part of your sleep. If I do that it counts that as "light sleep" if I don't move during watching TV in bed. It says I got X hours of sleep but that includes any time you spent laying in bed for any reason (i.e., watching TV, reading, etc.) before doing to sleep. Overall though it does what I intended so I'm giving it five stars. They could certainly make improvements but so far it's been great at giving me an assessment of my sleep and sleeping patterns overall. They want you to link it to other health apps and trackers and such so that's built into their app. For me that just takes up space because I only use this for sleep tracking. I would delete those parts if I could, as it just gets in the way of seeing how I did with my sleep. I am very pleased with the product overall and assume that future versions will be even better.

This is completely useless when it comes to tracking your sleep to find any problems which you may have to correct. I say this because most of the data is made up out of thin air. How can I say this you may ask. Well, I use two other sleep trackers. A Wellue wrist sleep O2/heart rate monitor which is dead on accurate. I know this because I took it to the doctor's office with me last time and wore it while they took my vitals and the readings were identical to the doctors machine. I also use the Snorelab app on my phone which records all my snoring and interruptions. This thing didn't match what I was seeing on those two other monitors at all. Here's a typical example of what this thing recorded for me last night. First, the main data area shows your Awake, Rem, Light, and Deep sleep times. There are two problems with this "data". First, only a Polysomnograph can tell you this as it connects electrodes to your head to measure brain activity. Last I checked this thing didn't have electrodes to connect to my head, so this "data" is being completely made up using whatever formula they have set in the app. Lastly, the data shown is completely wrong. I was awake most of the night last night, I have really bad insomnia, the reason I know I was awake is that every half hour I'll say the time out loud so that Snorelab can record it and I can go back and listen to it. Last night I didn't fall asleep until a little after 4am. Yet this this says I was asleep within 10 minutes and that I was asleep all night with no interruptions for 8 hours, even though I got up once and went to the bathroom. Second, the snoring sensor on this thing doesn't work. my Snorelab app says I snored for 2 hours and 9 minutes and I can listen to myself snoring as well as rattling off the time every half hour until 4am. Yet this thig says I didn't snore at all, zero, zilch, zippo. How can I believe that when I can hear myself snoring for over 2 hours in the Snorelab app? Thirdly, there's an area for "Breathing disturbances" which is completely useless as it only says "Few". What the heck is "Few", 1, 3, 5, 10? It would be nice if they could tell you how many and at what time but I know why they don't. Here to the data is made up. I got "Few" last night but my Wellue says I had none as it would show an O2 drop if your breathing was interrupted. I believe the Wellue, as I have mentioned it's dead on and lets you know when you move also. The last part is the heart rate area. This thing consistently measures a heart rate that's about 5bpm higher than my dead on Wellue monitor, but at least it sort of works unlike all the other things its supposed to measure. Another bad thig with this device is that you are required to have a wifi connection as it sends the data to their servers and then to your phone. This is completely needless, why can't I just have the data on my phone? That's what my Wellue monitor and Snorelab app do. They send straight to my phone via Bluetooth, no internet required. Here to I know why they do this, they collect your data. That's why the app needs the following permissions: This app has access to: Device ID & call information read phone status and identity Camera take pictures and videos SMS receive text messages (SMS) Identity find accounts on the device Contacts read your contacts find accounts on the device Phone read call log read phone status and identity Wi-Fi connection information view Wi-Fi connections Calendar read calendar events plus confidential information And that's just some of them. Why on earth would they need my call logs, contacts, and calendar events to track my sleep? Needless to say, this POS is going back for a refund. P.S. For all you people that give this a glowing review here's a little challenge for you. Go lay down for 2 hours without sleeping then check to see how long you were sleeping. I actually did that once in the middle of the day and it logged it as a nap. apparently I fell asleep in 0 minutes and slept for two hours. When in fact I was awake the whole time watching TV.

I've been using the Withings Sleep Tracking Pad for a couple of months now and overall, I think it's a really solid product. The setup was easy, all I had to do was slide it under my mattress, add it to the Withings iPhone app, and forget it's there. It tracks all the important metrics, heart rate, sleep cycles, and snoring without requiring me to wear anything, which is exactly what I was looking for. I removed one star from my review because the US version has less functionality compared to the European version. The EU version, called the "Sleep Analyzer," has sleep apnea detection but the US version does not, as it is still pending regulatory approval. It's not a deal-breaker, but I hope the missing feature will be available here at some point, especially considering the price point. Still, the data it provides is robust and has helped me identify trends in my sleep patterns. It syncs reliably over Wi-Fi, and the Withings app gives you a clear breakdown every morning. I also use a Withings smart scale and blood pressure monitor, and together they make a very comprehensive and seamless health tracking system. If you're already in the Withings ecosystem, this fits perfectly. It's not perfect, but it's close and for anyone who wants to better understand their sleep without wearing something on their wrist, it's hard to beat.

Ok, I do not ordinarily write reviews unless I am very impressed and this sleeping mat really impressed me. I have tried a variety of sleeping mats/sensors in the past and the single biggest problem with them all (other than this one) is that they require you to use your phone to record the sleeping data. With other mats, you need to remember to open an app on the phone and you need to store all the data on your phone, which gets very annoying after a short while. Not with this mat, the sleeping mat communicates with Withings directly over wifi and all your sleeping data is stored on their website. Your phone is just used to view the data whenever you want, you can delete the withing app from your phone and it will not erase the data. The other important thing about a sleeping sensor is the accuracy, a sleeping mat/sensor is no good if it is not accurate, and this one is meeting my accuracy standards. You do need to be careful where to put the sensor (they say under the sternum) but once you do that, then you don't need to worry about placement ever again, or even need to think about the sensor ever again. It just records your sleep every day without you ever having to think about it. This point is not to be under estimated, I have 10 years of daily weight data stored on the Withings website, because I use their weighing scale. And no, I am not giving them 5 stars just because I own their weighing scale, I would simply not bother writing a review if I was not truly impressed with the product. I am going to come back and update this review after 1 year, the true value of a good sleeping sensor is in being able to consistently produce a good measurement every day. Update after 1 month: 1. Robust: I have used it for a little bit less than 1 month now, and I have a reading from every day. This is a first for me, my previous sleeping sensors never made it so far. 2. Accuracy: Accuracy is not super good but not super bad either. If you lie still in bed and do not move, this sensor will put you down as "REM", and the other deeper sleep settings can be fooled too. I think i have to leave the bed or sit upright for it to think that i am awake, otherwise it thinks that i am asleep. If the sensor is able to measure my heartrate and i don't move much, it has me down as asleep. Not complaining to be honest, I am not sure how much better someone else can do either. 3. Speedy reading: Typically i get the results as soon as i get out of bed, within 5 mins. On a few occasions, it has take longer. Sometimes as long as 6 hours. I think the sensor tries to connect to the website, if it is not able to connect, waits for a few hours before retrying. Not sure exactly what happens in the few instances. But I have always managed to finally get a reading from the previous night, even with those delayed instances. I see a lot of negative reviews and I feel that this could be a cause of concern. When you don't see the results right away, you get nervous that the sensor could be broken. 4. Five Stars: Yes, I still give this product 5 stars despite everything. Competitors take note, this is the first time that a sleeping sensor has been able to track my sleep for as long as a month, and the data is stored safely in Withings website. I don't think any other sleeping sensor competitor can say they do as good a job, including the mighty Apple. I am afraid that making a good sleeping sensor is so hard, that people might simply think it is not worth the effort.

I purchased this sleep mat first week July 2023. It has been under the bed in continuous use for very nearly 24 months. I also have a Withings electronic scale which is another very helpful home health tool. I also used a SamsungWatch Pro as a part of an integrated home health monitoring solution. Note that Withings also produce a very good health watch (Scan Watch) which is well regarded. The correlation between the Samsung smart watch and the sleep mat is consistent in trend, but not absolute measurement. Also, be aware that sleep measurement is actually quite difficult, and to expect enormous accuracy from any of these devices is a bit unrealistic. What it does do, and both solutions do quite well is track your total estimated length of sleep. Thus, the measurements are in a sense relative to the measurement system used, in this case the Withings sleep mat. The Withings sleep mat however, has the advantage of a more comprehensive set of vital measures. These taken together with the sleep metrics can be very helpful in understanding your body's sleep dynamics, daily variance and rhythms. The latest version of the software, which is perhaps the most significant release in 2 years really upped the Withings sleep mat game. The results are night and day (pardon the pun) different. As such, I would recommend not considering reviews over 3-4 months old as these will likely be with an older software version. The new software tracks the same things as before, but now includes things like heart rate variance, motion and enhanced breathing disturbance. As such, it now presents a much more comprehensive view of your sleep pattern as it relates both to several vital measures and the more fundamental sleep/activity times. This is actually very helpful as it tends to give you a better perspective of the overall sleep pattern. Now results are always difficult to assess with a product like this. So first. The product. It has worked flawlessly for nearly 24 months without issue. So top marks for reliability. The software has been upgraded and is substantially improved over the 2023 version. So top marks for continued product development and enhancement. Noting that Withings does not charge any fees for the software use or upgrade. Top marks. The personal results are highly dependent on whether you choose to use this product as feedback not on your sleep - that is somewhat uncontrollable - but rather your sleep habits. If you take heed of the very useful feedback and hints, you can start to make small adjustments over time that - like any training - incrementally improve your sleep behaviors. Example, one of the most significant factors is the time you turn-in, and the time you get up. Minimizing variance here will result in improvements to your score. When I started using the sleep mat I was achieving routinely low 70's. After 20+ months I now regularly hit mid-80's and low 70's represent my bad days. In fact this year I have started to be able to hit high 90's with a couple of notable 100's. The impact of this is more energy, better mental acuity/clear thinking and significantly less fatigue. Also note that when your score drops something is going on. Perhaps you have an early flight, new medication, or simply did not take the necessary steps to prepare for bed the night before. A quick check on your phone and you can quickly put 2+2 together and take action - if needed. After all life happens., and thats the thing be aware that the score is not a critique on you, but rather a guide to help you improve it. Sleep is fundamental to well being, so if you have an illness the score will likely drop (unless there is an impacted sleep element in the medication.) Thats okay, because you should realize you may need more rest, and perhaps take a little time out of your schedule to make up for the loss. If you have a smart watch it is easy to cross-correlate measurements and get a sort of digital second opinion. Rarely have I seen complete 180 between results - unless for example I am not wearing said watch. In the end you will get out of this product what you put in. If you have no intent to make a change, and it is idle interest, then a smart watch may suffice. However, if you want to really start modifying your behavior and are looking for coaching and guidance this product is for you. No product can guarantee any kind of health benefit as there are too many personal variables beyond its control or frankly sometimes yours. So this product is highly recommended to anyone that needs to monitor their sleep behavior, and body vitals with an intent to take personal action on the results. A restful sleep is possible, it may take longer than you expect. But it really is possible. Finally, the real question does this product represent value for money or is it simply a nice to have. The way I would rationalize that is what is a more energized, less fatigued self worth to you? Or put another way, let's say you get 1-3 hours more useful, more enjoyable time per day that seems a huge upside relative to the modest investment made in this product. In two years at 1 hour a day more rested (say) that represents 8.7 weeks at 12 hours a day over two years for an original investment of $120. So on that basis, for this customer, this product represents excellent value for money. But thats a personal opinion.

Tried wearables with limited success. Gave up on them and tried this sub-mattress device. Great decision! Once I properly placed and calibrated this pad, I began getting very useful sleep data that 1. Allowed me to develop a consistent understanding of trend and pattern data in my sleep cycles 2. Accurately tracked the number of times I woke up, length of time to fall back to sleep, if I got out of bed (always to use the bathroom in my case) and how often I get up, when I sleep deeply (slow wave) during my sleep cycles. 3. Understand which meds, products and sleep hygiene steps impact sleep positively, negatively or not at all. I'm using the Withings pad to understand how supplements affect my sleep based on amount and time of evening they're taken. This pad, at least in my case, provides just enough accurate and detailed information on my sleep cycles that I can test making adjustments in my life to determine if they're helping to improve my sleep. My hopes are high that this product will help me to identify lifestyle and supplement changes that result in better sleep and hopefully healthier wellness as a result. So far, I highly recommend it. 5-MONTHS REVIEW: Been using the Withings sleep tracker for 5-months, and I'm more impressed than I originally was. I've been able to measure the impact of various sleep hygiene activities and supplements on my sleep score with great effect, allowing me to understand what works best for me, individually. While I've made great strides in getting better sleep, its still a work-in-progress as its only been 5-months with my Withings. I really am confident that the sleep data is accurate most of the time as it often matches my anecdotal experience after waking. I've found it to be of lesser accuracy only about 10% of the time, which is exceptional compared to my experience with wear-ables. I can't say enough how much I love the Withings Sleep product, and I've recommended it to friends. Honestly, the Withings pad is a bargain at under $100 US, as wear-ables costing 3X as much are far less useful for measuring and adjusting efforts for better sleep. Knowing what I know now, I'd pay much more for this product simply because the value is there in every way.

My Withings Sleep mat is back in its pretty box and ready to send back to Amazon before the 30 day return window expires. I tried very hard to make it work, and 30 days was not enough. As many other users have reported, I saw an initial ten days of believable sleep data reported on the iPhone, and a subscription is NOT required for that. On the eleventh evening, we both laid on the instrumented side of the bed for a while. That night, the sleep report showed missing hours of sleep. The next night showed only a little sleep. The next night showed no sleep at all. I lept into test engineer mode. The home router showed the Withings Sleep mat was 'off' and had no IP address. Hmmm. I set up a wifi access point on my laptop to wireshark it. The first night was misspent with the mat asking for DHCP from a wrong DHCP server ip address and getting rejected. What I do not know of networking fills many books, but the next night I got lucky and captured traffic. When there is no sleeper, the mat remains quiet. When a sleeper is present, from time to time throughout the night, the mat uses DHCP to get a new IP address, uses DNS to find ws.withings.com, sends TLS3.1 encrypted traffic, and releases the DHCP lease. Inscrutible. I considered the acoustics. Ballistocardiography measures the recoil of the body when the heart shoots blood downward. According to a 1951 pdf, "MOTION OF THE THORAX DURING THE HEART CYCLE", q.v., the thorax converts head-to-toe signal into dorso-ventral and lateral signals, both equally at about 40% strength, and the best signal is opposite the xiphoid, or bottom of the sternum. My mattress is a 73" wide Ikea Myrbacka, 3" of memory foam over 6" of other foam, and very heavy, on a slatted bedframe. The signal is a time varying scalar, and the mat bladder is like an eardrum, so I created a soundbox around it using two 2x4 foot thin plywood sheets sandwiched with 3/4" sticks on the two long sides, and a further 1/4" taken up by papers to leave the mat in about a 1/2" space minus whatever the plywood sags. That night I also discovered the Withings App checkbox [x] "Increase Sensitivity", and it captured the sleeping partner in the absence of the targeted sleeper. So I reduced it to 2x2 foot. I also know that many firmwares run a while, and fall over. So I added a smart outlet to cycle power to the mat daily at midday. I considered to place the mat above the mattress, but my wife would not lay on it. I also considered to slice the mattress foam to embed the mat in it, but my wife would not allow it. In a last ditch effort to see success, I did a factory reset and placed it under only a pillow under my thorax, and it captured only intermittent data. Valuable diagnostics can be had from the Withings.com login, and from a free IFTTT.com account. I easily created two applets there to send email upon in bed and out of bed events. In one night, I counted 143 each of in-bed and out-of-bed events! Reviewing the online sleep data, there is no sleep recorded for any evening hours before midnight on any night except on the fateful eleventh night, neither before nor after that day, but the iPhone does correctly show sleep both before and after midnight. I cannot fathom the failure mode, but with 50% of 5 star reviews and 20% of 1 star reviews, Withings had better try to solve it. The next shiny thing in my sights is a Google Nest Hub Gen 2 with a radar chip to detect sleeping, and I already installed a free SleepScore App to try out.

Les mesures sont précises, les nuit bien analysées. Les phases de réveil sont bien visibles. Et même les petites siestes sont prises en compte !! Se fait vite oublier, et les résultats mis à jour quotidiennement. Juste une petite remarque, les résultats ne sont pas affichés immédiatement car envoyé en wifi aux serveurs Nokia. Etant donné qu'ils sont envoyés lorsqu'on est plus au lit (pour éviter une exposition aux ondes je suppose), il faut bien attendre une petite heure après le levé avant de pouvoir lire les résultats de la nuit. Super produit en tout cas !

I’ve had various sleep trackers, from Sense which required a simple sensor on the pillow but sadly went out of business so their cloud stopped working, and Beddit (now owned by Apple) which is actually probably better than this but there are some caveats (it requires Bluetooth and the Beddit App open). Nokia’s efforts don’t require anything complex, the sensor goes under the mattress - I have a Simba and it’s perfect. You then get into bed and that’s it, just forget about it. It tracks heart rate and sleep quality through the night and simply uses WiFi to send this to the cloud, finally being displayed in the Nokia Health app. If you have an iPhone it can then send the sleep data (but not heart rate data) to Apple Health. Your data belongs to you, and this is important. It’s not locked away like Fitbit does. In terms of accuracy, I find it really quite good. It senses bed time perfectly, and it can tell the difference between sitting on the bed and getting into bed. Sleep detection seems amazing, it’s not always sleep time when getting into bed, and the app reports time to fall asleep. Sleep duration, and depth are tracked also. Of course! Detection of waking up in the morning is good, but it can be a bit hit and miss with getting up time. I do like to laze in bed some days, which probably confuses it. It’s not quite as good as time to sleep detection, but it’s still great - but again there is nothing to do. Just get up and it’s done. It cannot be more simple. All in all, this is highly recommended. It’s excellent value for money.

I bought this immediately after finding it. The idea of getting my sleep tracked without having to wear something was exactly what I was looking for. I watched a video review prior to buying which helped to anticipate how accurate the measurements would be. Overall, it gets my sleep patterns pretty right on, and I sleep with a partner in the bed as well as a dog sometimes. Very impressed that they can detect sleep start and end, heart rate, and sleep depth through maybe 10" of mattress.

Excelente medidor de la calidad del sueño. Recomiendo ampliamente este producto y revisar los demás que ofrece Nokia/Withings. Yo tengo la báscula, el medidor de presión, el termómetro y este dispositivo de medición del sueño y puedo contar que son unos excelentes dispositivos.

My first one lasted five years. Let's hope I get the same or more out of this one.
