Withings Sleep Analyzer review: advanced sleep tracking made easy

Samuel Gibbs


The Withings Sleep Analyzer is a sleep tracking mat that’s simply easy to live with (...) The data it produces is good and the way it’s presented in the excellent Health Mate app is easy to follow and track across days

Very powerful & helpful tool to improve your Health! For a limited cost, you get like a real Pro ’s equipment that ‘s help you balance you life on the right side for your health. For some’s one who cares about it, it is a must.



The sleep analyser is really useful at recording my sleep even though I get up and down to feed my baby son. I also am reassured by the sleep apnea detection .



Being a patient of acute sleep apnea, and having to wear a CPAP to sleep, I was missing statistical and realtime data on how effective my sleep was. This device and app has changed the way I understand my sleep quality. It give me data that then allows me to adjust my mask or replace it. It is a powerful tool to understand sleep quality. Use it and you will not be disappointed.



I was diagnosed with obesity and I was told snoring could be a sign of sleep apnea, so I was suggested to get a monitor. After reading online I found Withings, and love it, it is just perfect, easy to use/install, and the app is just as pretty as can be.



Pure magic. Have no idea how that measures all the data through a thick mattress, but it works and works good. The only things is that sometimes if I lay still watching TV before falling asleep it detects those moments as a light sleep. I can edit it later though.



Useful addition to my collection of health and wellness tools. It helps me to understand if I'm really getting enough sleep, or I'm feeling tiered when I wake up in the morning because of something else - maybe my lifestyle.

I've been using Sleep Analyzer and the Body+ scale. Middle-aged, I'm in good health with a normally active life-style and I've tried a few devices to monitor some body functions (smartwaches mainly). The Withings products are no doubt the best, the ones that seem the most trustworthy in terms of measurements and reliability of data. The company seems to be primarily a health monitoring company and not one that primarily makes watches, or provides computers or email services of what have you. Monitoring health is at the heart of this business and so naturally, they do it well and the tools are easy to use. In fact, my next smartwatch might just be the Withings one (especially if they make a sport-focused model) rather than one of the traditional brands.



Product itself is fabulous! Easy setup, then hands off from there on.App... Could use some work... Basic info is reasonably easy to access, but cluttered with other health stats, and buggy. In theory should be able to integrate with other stuff, but is proving difficult



We purchased the withings scales , sleep mat ,watch ,that all link together via the app .well worth whatever my husband paid for it excellent bit of kit, i suffer with restless leg syndrome ,+ sleep apnea ,the app + mat ,tell me how many times I've got up in the night +detects how bad my apnea was ,could not be without it now.



It is a great piece of kit. Easy to install and it just works. Helps me understand my sleep patterns and automate my home.

I received this as a gift as I had been looking but could not justify the cost. Really pleased with this gift as it gives great insights into your sleep and provides advice on how to improve sleep scores

Sleep analyzer is the best X-mas gift for long time. It has given me new insights to my sleeping, and what is the most important, it has really made me think about sleeping rhytm and other things that effect on sleeping quality. For me this device is fantastico :)



The Withings Sleep Analyser has learnt me much more about my sleep than I could possibly imagine. With the sleep analyser I can now determine the most suitable time of the day to take my medicine, thus minimizing the negative effects on my sleep.

Straight forward installation and easy to just sleep and everything syncs to the app



Easy to install, easy to use and easy to share results with medical practitioner. Showing why I'm tired during the day and sharing this with doc



One of the best bits of tech kit I've bought. Awesome data the morning after the sleep before.

Another great Withings health product to add to my weighing machine and blood pressure monitorVery easy to set up and access information and really useful in trying to change habits to improve our sleep It diagnosed sleep apnea in my wife which I am getting checked out

I've sued withing products for some time (scales, bp monitor) and found the sleep analyser a great addition. The device is very easy to setup and makes tracking sleep quality a breeze. The data helps form a picture of my sleep and trends over time. I share the information gathered with my sleep specialist and it assists him (and me) in the treament of insomnia.100% recommended.



Really easy to install and one starts getting useful insights immediately. I've started doing some sleep hygiene and started going a bit earlier to bed to try to get 7+ hours of sleep, which with a <1 year old baby can be challenging. But overall I've improved my sleep score already! This is great outcome for such invisible product!
