Non-wearables like mats, mattress covers, and pods
If you're looking for a sleep-tracking device that doesn't need to be worn, you might want to consider a mat, mattress cover, or pod. These non-wearables offer a convenient way to track your sleep without having to remember to put on a device every night.
One option is a sensor-packed mat that slips underneath your mattress, such as the Withings Sleep Tracking Mat. This type of mat tracks your movements, breathing, and heart rate throughout the night. It can also detect snoring or other sounds and alert you to potential breathing problems that could indicate sleep apnea. The Withings Sleep Mat proved surprisingly bad at determining sleep stages but did quite well with sleep efficiency. However, it's important to note that bed trackers like this one may sometimes pick up other people or pets sleeping in your bed.
Another option is a mattress cover, such as the Eight Sleep Pod 4 Cover and Hub. This cover has numerous sensors to track temperature (ambient and body), heart rate, heart rate variability (HRV), respiratory rate, movement, and sleep stages. Each morning, it gives you a sleep score out of 100 and offers charts showing your sleep stages, health metrics, sleep latency, and consistency. The Pod 4 improves on previous versions by being quieter, more comfortable, and adding manual controls.
For those who want a more comprehensive system, the Chilipad by Sleepme is a non-wearable sleep tracker that works with a Dock Pro Sleep System to provide real-time, AI-driven temperature adjustments to create your ideal bed climate. The tracker fits seamlessly at chest level on your mattress and tracks sleep metrics including heart rate, respiratory rate, and sleep staging. It syncs your data with Apple Health and Google Health Connect for actionable insights. The Chilipad tracker is also low-maintenance when it comes to cleaning, with a removable and machine-washable sensor cover and a sensor pad that can be easily wiped down.
Finally, if you're looking for a device that can track your sleep without any contact at all, the Google Nest Hub 2nd Gen uses radar to track your sleep. It also has a microphone to detect snoring, sleep talking, and other nocturnal sounds. However, it's important to note that this device has been known to overestimate REM phases and miss periods of wakefulness.

How smart movement trackers monitor sleep
Sleep tracking devices can be a useful tool to help you recognize patterns in your sleep habits. They can be used to determine whether you feel more sluggish sleeping from 10 pm to 6 am or from 11 pm to 7 am, whether you sleep better when your bedroom is cooler, or whether your sleep is disrupted if you have caffeine after lunchtime.
Sleep tracking wearables are usually in the form of rings, watches, or other fitness trackers that you can strap to your wrist. They can also come in the form of a sensor-packed mat that you slip underneath your mattress, or a mattress cover that regulates your temperature.
Sleep trackers can monitor a range of metrics, including:
- Heart rate
- Heart-rate variability (HRV)
- Body temperature
- Blood-oxygen rate
- Menstrual cycles
- Sleep cycles
- Total sleep time
- Sleep efficiency
- Resting heart rate
- Restlessness
- Sleep latency (time to fall asleep and get up)
- Sleep consistency
- Respiratory rate
- Sleep stages (awake, REM, light, and deep)
- Movement
While sleep trackers can be a useful tool, they can also be inaccurate due to their reliance on actigraphy, a technology that measures movement. For example, in some tests, sleep trackers assumed that the tester was sleeping when they were awake but lying still. For medically accurate sleep-tracking data, a polysomnography (PSG) test is the best way to go. This is the gold-standard sleep study method, which records brain waves, heart rate, blood oxygen level, respiration, and movement.

The accuracy of smart movement trackers
The Oura Ring, a competitive sleep tracker, has been reviewed as one of the more accurate fitness trackers. The ring has three hospital-grade sensors: infrared photoplethysmography sensors for heart rate and respiration, a negative temperature coefficient (NTC) sensor for body temperature, and a 3D accelerometer for movement. The Oura Ring 4 has smart sensors that allow more accurate and continuous data capture. It also has improved comfort and flattened sensors that make it easier to wear over time.
The Withings Sleep Analyzer, on the other hand, has been questioned for its accuracy as it assumes that the user is trying to sleep if they are lying still in bed, which can skew the sleep score. The Google Nest Hub 2nd Gen has also been found to consistently overestimate REM phases and miss periods of wakefulness.
For medically accurate sleep-tracking data, a polysomnography (PSG) test is considered the gold standard. PSG records brain waves, heart rate, blood oxygen level, respiration, and movement, and the data is interpreted by a healthcare professional. A 2017 study found that the Fitbit Charge 2 detected sleep onset with 96% accuracy but overestimated time spent asleep by 9 minutes on average. The Fitbit detected light sleep with 81% accuracy, deep sleep with 49% accuracy, and REM sleep with 74% accuracy.
While sleep trackers can provide useful insights into sleep patterns, it is important to take the numbers with a grain of salt and consult a healthcare professional for any serious concerns about sleep quality.
