Withings Sleep Analyzer in the test ›Macerkopf

Sleep disorders can be a real problem, and many don’t even know they suffer from them. Headaches and decreased concentration and performance are just a few of the symptoms that can occur due to a sleep disorder. The Withings Sleep Analyzer should remedy this or get to the bottom of sleep. We took a closer look at the clinically proven sleep tracker and show you how you can set up your own small sleep laboratory.

Improve your own sleep

In contrast to most other sleep tracking devices, the Withings Sleep Analyzer is not worn on the body. The sensor mat fits under the mattress and then no longer needs to be moved. Once it is properly placed, you can start monitoring sleep quality.

Thanks to the combination of two powerful sensors that register audio signals and movements, the sleep analyzer should not only measure the sleep quality precisely, but also help to improve sleep.

The noise sensor measures audio signals such as snoring and sleep apnea. Sleep apnea is a condition in which people experience breathing interruptions during sleep. Untreated sleep apnea is associated with a number of health risks and can significantly affect quality of life and well-being.

The pneumatic sensor registers movements such as respiratory rate and heartbeat as well as body movements. In combination, the sleep quality can be determined from the recorded data. With the help of the results, you learn at which points you can improve your sleep and thus your own health.

Setup process

In principle, the sensor mat is easy to set up. But there are a few things to consider. So the device needs a socket. However, the cable is relatively well sized with a length of 2.80 meters. If things get tight, an extension cable helps.

The mat should be placed approximately at the height at which your heart is in the lying position. The sleep sensor should not be placed under the head or at the bottom of the bed. It may take a few tries to get the perfect placement. Ultimately, we didn’t pay too much attention to the position and were very happy with the results. However, you should make sure that the mat does not pick up the signals of the adjacent partner. The sensor mat is so thin that you can’t feel it through the mattress and of course you can’t see it.

Practice use

The Sleep Analyzer uses the Health Mate app, with which all other Withings devices are also connected. The synchronization takes place via WLAN directly into the Withings cloud. During the sleep phase, the mat puts the radio on pause so that we do not sleep on a transmitter.

Sleep tracking is the focus of the mat. The recorded sleep pattern provides information about how much light, deep, and REM sleep we get per night. After combining this information, we get an evaluation of the sleep quality, which is also calculated based on the total duration of sleep and the time in the recovery phases.

The Health Mate app shows in detail how good the sleep quality was in the past night. Here you can even see the exact percentages of the sleep phases, in addition to the recommended length for each phase. The app lists the information on snoring and sleep apnea, which are recorded with the integrated microphone, separately. If you don’t feel comfortable with the audio recording, you can simply deactivate it in the Health Mate app.

The great thing about our new sleep laboratory is that it not only provides sleep statistics, but also offers advice on how we can improve our sleep values. These tips will not be new to those who have already worked intensively on the topic, but all those who have not yet read the relevant literature will benefit from the help.

It is also interesting to record the heart rate, which is continuously saved as an average value. It works without a cuff or electrodes. Withings uses a ballistocardiogram for this. This is a record of the body movements that are triggered by the mechanical activity of the heart.

Smart home integration

But that’s not all the sensor mat can do. It is also suitable for IFTTT (If This Then That) actions. So a lot can be automated with the Sleep Analyzer. An account with the online service IFTTT is required. Connections to other devices that also support IFTTT can be established via its server.

Once set up, the coffee machine switches on, for example, when the system notices that we have got up. In the test, switching on the bedside lamp automatically when you lay down in bed proved to be extremely convenient. IFTTT generally offers a variety of possible uses, which you can also configure yourself.

So far, smart home integration has only recognized when someone is lying on the sensor mat or getting up. In the future we would like that sleep phases can also act as switches. Then it would be possible, for example, to switch off the lights or the television automatically when we fell asleep.


Even if the Withings Sleep Analyzer does not protect against snoring or bad sleep, the sensor mat has presented us with a surprisingly comprehensive analysis of the sleep patterns. The data can then help to understand a problem or to become aware of one. The app supports us with background information and recommendations. The setup was straightforward and the system is easy to use.

We were not able to compare the measurement results with a sleep laboratory, but the data recorded in the practical test left a thoroughly conclusive impression. According to the manufacturer, the sleep analyzer was developed in collaboration with sleep doctors from the Béclère hospital in Paris and tested extensively using data from polysomnography analysis (PSG), the standard for sleep diagnostics.

We see the smart home integration as a gratifying bonus. The Withings Sleep Analyzer is available at Amazon for 129.95 euros.
