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

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.

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 informationread phone status and identityCameratake pictures and videosSMSreceive text messages (SMS)Identityfind accounts on the deviceContactsread your contactsfind accounts on the devicePhoneread call logread phone status and identityWi-Fi connection informationview Wi-Fi connectionsCalendarread calendar events plus confidential informationAnd 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.
