The EMFIT QS was originally developed for athletes, but it makes a fantastic sleep tracker for anyone interested in improving their health and sleep patterns. Like the Beautyrest and Withings, the EMFIT QS is a contactless device; it uses a measuring strip that is placed under your mattress. This strip uses ballistocardiograph and sensitive compression sensors to take readings on your sleep data.
The EMFIT QS is more than a standard sleep tracker. It not only measures breathing, deep, REM and light sleep, heart rate, and restlessness, but also total recovery, recovery efficiency, and night heart rate variability. This device is highly effective at picking up spontaneous wakening during the night and processing the time asleep, but it does struggle to differentiate between sleeping and relaxing in bed.
While this device doesn’t offer sleep coaching, there is a great deal of data to help you to assess your sleep patterns. There are visual data representations in multiple graphs, including heart rate variability, respiration, and sleep stages. All of this data will help you to sleep better and become healthier. The device gives you detailed descriptions of your sleep quality and recovery progression to help you to make well-educated choices for workouts and other activities during the day.
There is nothing to wear, and the EMFIT QS is easy to set up. There is no need to worry about turning the device off or on, simply play the sensor under your mattress, and the QS will start measuring automatically.

The MorePro offers a variety of features to enhance functionality beyond a sleep tracker. The sleep monitor does automatically monitor you, displaying the data on the compatible app, including wake up times and periods of light and deep sleep. There is also a heart rate monitor, blood pressure monitor, and daily activity tracker to help you to develop healthy habits and a healthier lifestyle. There is even a sedentary reminder to help you stay energized, making this one of the best activity and sleep trackers.
The Beautyrest Sleeptracker is the best non-wearable device, sitting under your mattress. This provides a contactless tracker that you don’t need to wear. The sleep data is sent via a small data processor to the smartphone app that’s simple to set up. There are even app videos to take you through the setup. Once your Beautyrest is configured, it can be switched on, and it will automatically track your sleep when you’re in bed, providing accurate and consistent measurements.

One of the most impressive features of the Beautyrest is that it doesn’t mistake resting in bed for sleep. It can also identify significant periods of waking during the night.
The Beautyrest also excels other models in sleep coaching. While many trackers provide generic coaching tips, the Beautyrest provides recommendations based on your sleep data and results. In fact, the more information you provide, the higher the standard of coaching. So, it is well worth taking a few minutes to answer the questionnaires, as you will get more helpful advice based on how you sleep after less active or stressful days.

Things to Consider
Sleep tracking devices have become popular recently, particularly for those who have difficulties falling or staying asleep. These devices can measure and monitor sleep patterns, heart rate, and movement, but may also monitor snoring and other sleep disturbances. With so many different types of device, features, and systems, it can be a little overwhelming to choose the best one for you. Fortunately, we’ve compiled a buying guide to help you make your purchase decision.
Features to consider while choosing sleep tracker
Many sleep tracking systems on the market today are very highly advanced, recording sleep data and providing analytics to help you adjust your routine for better sleep. However, it is important to look for features that will fit with your lifestyle and habits. Some of the best features for most users are an alarm, heart monitor, and sleep coaching tips.
Sleep trackers generally fall into two categories; wearable and non-wearable. Wearable sleep trackers typically provide more than just sleep data; they record your physical activities throughout the day and night.
Most sleep trackers are worn on the wrist, but there are ring types like the Motiv. Most wearable sleep trackers use accelerometers to monitor your movement. This provides readings that can determine if you enjoyed a peaceful and relatively still night or slept fitfully.
Advanced wearable trackers also go a step further, evaluating your sleep quality based on the stages of different sleep cycles. This is often displayed as a graph so that you can see the times when you were most fitful or slept well.
Non-wearable sleep trackers tend to be a good option for those who don’t like wearing a device but want to monitor sleep activity. These non-contact devices tend to record sleep data using movement sensors or infrared technology. The sensors connect to a smartphone app, but some can also work with home automation systems. For example, the Withings sleep pad can integrate with your smart home systems using IFTTT. Most non-wearable sleep trackers monitor heart rate, with non-invasive measures since there is no contact with your skin.
Unlike wearable models, non-wearable trackers are designed exclusively to monitor your sleep data and will not track your daytime activities.
Wearable and non-wearable sleep trackers all tend to require an app. The data from the device is typically compiled by the app to display graphs or other visuals to help you to analyze your sleep patterns. Therefore, it is important to choose a device that has an App compatible with your smartphone. Fortunately, most sleep trackers are compatible with Android and iOS, but be sure to check whether the tracker app is compatible with your specific smartphone OS.
It is also worth bearing in mind that some sleep trackers can also display data on your PC. Although many users will appreciate the flexibility of using a smartphone, some may prefer to analyze their sleep data on their PC.
When choosing a sleep tracker, it is also important to assess comfort. Wearable trackers can often be worn throughout the day and night, so it is crucial that the device is comfortable. In fact, some manufacturers even specify that devices should be removed periodically to avoid skin irritation. Since many devices are waterproof, it can be very tempting to wear a device 24/7. When assessing sleep trackers, you need to be realistic about what you find comfortable. If you don’t tend to wear a watch, you may find a wrist design wearable uncomfortable, or it may take a little time to get used to it. Likewise, a ring wearable may be only appropriate if you are comfortable wearing rings. If you don’t like the feeling of wearing jewelry, a non-wearable sleep tracker may be more appropriate.
Night data recording
Most sleep trackers use actigraphy to measure your sleep patterns. Both wearable and non-wearable devices track your movement as you sleep, which is translated into periods of sleeping and wakefulness by the software. This provides a convenient way to study your sleep pattern without needing to visit a sleep clinic.
Wearable devices can be worn 24/7, which also allows you to track periods of inactivity and sleepiness during the day. Your movement rate may suggest times when your energy lulls that could provide insight into your sleep, rest, and dietary patterns to promote a healthier lifestyle.
Studies suggest that generally, actigraphy devices such as Fitbit are considered accurate to track sleep in a healthy adult with a “normal” sleep pattern. If you have a sleep disorder, the device may not be as accurate during periods of very disrupted sleep.
Since sleep trackers often measure movement, some less sophisticated devices may struggle to distinguish between rest and sleep stages. However, many of the devices we’ve featured here, such as the Fitbit Alta HR, are accurate at telling the difference between when you are sleeping and resting.
The price of sleep trackers can vary greatly. Generally, wearable devices tend to be more costly than non-contact trackers, but there are some reasonably priced wearable sleep trackers. For example, the MorePro Fitness is our best budget pick. This device automatically monitors heart rate and blood pressure in real time, in addition to recording your calorie consumption, steps, distance, and sleep data. The accompanying app allows you to review your stats easily, and there are reminder functions.
While the budget is an important factor, it should not be your only consideration when you make your purchase decision. It is important to look at the overall features and functions offered as you may prefer to pay a little more and get a device that has additional functionality to suit your lifestyle and habits.
To further help you to make your purchase decision, we’ve compiled some frequently asked questions.
The mattress thickness should not have an influence on the measurement of an under-mattress sleep tracker. For example, the Withings sleep mat has been tested with mattresses from 4 to 15 inches to ensure accuracy.
Generally, non-contact sleep trackers offer a more convenient solution as you don’t need to wear any devices. However, these devices tend to use sensors that may be affected by sleep partners or by frequent movement during the night. For example, some sleep mats may struggle to differentiate between lying in bed reading and sleeping.
Since sleep trackers are “wellness” devices, they are not regulated by the FDA, so claims about detecting issues like heart problems or sleep apnea cannot be substantiated. However, many sleep trackers measure heart rate, which can highlight potential issues that require further investigation.
Deep sleep is the third stage of our sleep cycle, and it occurs when the breathing, heartbeat, brain waves, and body temperature are at their lowest. In healthy adults, between 13 and 23 percent of sleep is a deep sleep. So, in a typical 8-hour night’s sleep, approximately 62 to 110 minutes would be a deep sleep. However, as we age, we tend to require less deep sleep.
If you want to track your sleep, are into fitness, and like the idea of wearing a smart device, then the Fitbit One is an excellent choice. When many people think about fitness, and sleep trackers, they immediately think about a Fitbit. The Fitbit app is excellent, and you can track your fitness, activity, and sleep, with goals and motivation. You can even log your food, workouts, and other activity to help improve your overall health. While the Fitbit does have a unique charger, there is up to a 10-day battery life.
Another wearable that we rank highly is the MorePro Fitness. This is a more budget-friendly option that still offers excellent functionality. The high definition color screen provides a bright display, and the device can be used during swimming and cold showers. You can even receive notifications, alarm alerts, and periodic reminders.
Overall, the EMFIT QS is our pick as one of the best sleep trackers. This system developed for athletes may have a steep learning curve to analyze the data, but it does provide accurate insight into your sleep patterns. The EMFIT QS measures deep, light and REM sleep, restlessness, heart rate, and recovery efficiency. The sensors are highly effective at monitoring the time spent asleep and the periods of waking during the night. This produces plenty of data that is collated into multiple graphs to help you become healthier.
