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.

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.
