Withings Sleep Analyzer / Sleep — my top pick. It slips under the mattress and tracks sleep duration/stages, heart rate, breathing, interruptions, and snoring. It doesn't need to be worn or charged. Current product listings show it around $100–$170, depending on seller.
Beautyrest Sleeptracker — another under-mattress option, particularly interesting for couples who want separate sleep tracking.
The [Withings Sleep Tracking Mat ](https://www..com/en-us/products/sleep) is the premier and most widely recognized choice for a contactless, under-the-mattress sleep tracker.
Can you recommend a sleep monitor that goes underneath the mattress?
Emfit QS — more aimed at people interested in HRV/recovery and detailed biometrics, but considerably less mainstream.
Eight Sleep — excellent if you also want the bed to heat/cool each side, but it's a much more expensive mattress-cover system rather than a simple pad you slide underneath.
If you just want “put it under my mattress and forget about it,” I'd buy the Withings. It has been consistently recommended as one of the strongest mattress-based trackers, and the official technology uses a pneumatic sensor underneath the mattress to detect breathing, heartbeat and movement.
If you tell me your budget (e.g. under $100, $200, or $300) and whether you need sleep-apnea detection, heart rate/HRV, or just basic sleep tracking, I can narrow it to the best 2–3 choices.
Placement: Slides flat directly under your mattress (compatible with 4 to 15-inch thick mattresses) and sits over the bed slats or box spring.
Key Features: Tracks sleep cycles (deep, light, REM), continuous heart rate, snoring detection, and breathing disturbances/signs of sleep apnea. It connects via Wi-Fi and syncs automatically to your phone.
*Livindi Bed Sensor *
Price: Around $130
Placement: Placed very close to the surface (often under the bottom sheet or very thin layer).
Key Features: Primarily built for monitoring resting vitals like real-time heart and respiration rates, as well as out-of-bed movements. Note that it requires a companion tablet system and ecosystem for full remote tracking.[2][3]
If you'd like, let me know:
What specific metrics you care about most (sleep apnea detection, heart rate, or just sleep cycles)
What kind of mattress you use (foam, innerspring, adjustable bed)
I can help you confirm compatibility or look for alternative smart home setups.
My top recommendation is the Withings Sleep Tracking Mat. It sits underneath your mattress, so you can monitor your sleep without wearing a watch, ring, or wristband. It’s a good choice if you want something you can set up once and leave in place.
The main things I’d look for are sleep duration, nighttime awakenings, breathing and heart-rate trends, snoring detection, and whether there’s a recurring subscription fee.
My top picks
1. Withings Sleep
(Best overall)
Official price: $199.95
Tracks sleep stages, duration, heart rate and snoring.
No charging and no mandatory subscription for basic sleep history.
Aimed at people interested in heart-rate variability (HRV), overnight recovery and training readiness.
More specialized than a basic sleep tracker.
Check current availability and pricing before choosing it.
Which would I choose?
I'd start with the Withings Sleep for straightforward, everyday sleep tracking. Its standard U.S. model is a wellness tracker, though, not a substitute for a medical sleep study or a diagnostic device for sleep apnea.
One question so I can narrow this down: What do you most want the monitor to tell you?
The Withings Sleep Tracking Mat is the top recommendation for a non-wearable, under-the-mattress sleep monitor , generally priced around $130 to $200.[1]
Design : A thin, discreet pad that slides underneath your mattress (compatible with thicknesses between 4 and 15 inches) at chest level.
Tracking Features : Monitors sleep cycles (deep, light, and REM), sleep duration, heart rate, snoring, and breathing disturbances.
Connectivity & Sync : Automatically syncs data via Wi-Fi to your smartphone app every morning so you can review your daily Sleep Score.
Smart Home Integration : Includes IFTTT compatibility, allowing you to trigger automation like turning off lights or adjusting the thermostat when you get into or out of bed.[1][2]
If you'd like, let me know:
Do you need a monitor for an adult or an infant?
Are you looking for specific features like smart home integration or medical-sharing reports?
I can help narrow down alternative options that fit your exact needs.
If by sleep-tracking mat you mean something that sits under your mattress so you don't have to wear a ring or watch, the Withings Sleep Analyzer is the one I'd look at first.
No subscription, which is a significant advantage for a device you may use for years.
Reviews in 2026 generally find it unobtrusive and useful for identifying sleep patterns. WIRED reported that its readings tracked closely with a smartwatch during testing.
It doesn't change the feel of your mattress once installed.
The other option worth considering
If you want sleep tracking + active cooling/heating of your bed, the Eight Sleep Pod 5 is much more sophisticated. It tracks metrics such as sleep stages, HRV and respiratory rate while independently regulating temperature on each side of the bed.
Eight Sleep Pod - $3,595.00 (Eight Sleep)
The tradeoff is price and subscription requirements; the Pod 5 is in the several-thousand-dollar range, whereas the Withings is primarily a sleep-monitoring device.
Bottom line: If your goal is “I want the best practical under-mattress sleep tracker without wearing anything”, I'd choose Withings Sleep Analyzer. If your bigger goal is “I want to optimize my entire sleep environment, especially temperature”, look at Eight Sleep.
If you tell me your budget (e.g. <$200, $500, $2,000+) and whether you care about sleep apnea, snoring, HRV, or temperature control, I can narrow it down further.
When it comes to non-wearable, under-mattress sleep tracking mats, the undisputed gold standard on the market is the [Withings Sleep Tracking Mat ](https://www.crutchfield.com/I-rGPSc1AF7/p_238703935/Withings-Sleep.html) (also known as Withings Sleep / Sleep Analyzer). Because most consumers prefer smartwatches or smart rings for tracking, the under-mattress category is niche, but Withings dominates it completely by offering a set-it-and-forget-it experience.[1][2]
The Top Choice: Withings Sleep Tracking Mat
Design & Comfort: It is a thin, discreet pad that slips entirely under your mattress (compatible with thicknesses between 4 to 15 inches) at chest level. You don't have to wear anything on your wrist or finger.[1][2][3]
Sleep Metrics: It tracks deep, light, and REM sleep cycles, total sleep duration, interruptions, and how long it takes you to fall asleep or wake up.[1][2]
Vitals & Health Tracking: It monitors your continuous overnight heart rate and detects snoring as well as breathing disturbances (helpful for screening indicators like sleep apnea).[1][2]
Connectivity & App: It automatically syncs via Wi-Fi to the Withings app every morning, giving you a daily Sleep Score and long-term trends you can even export into a PDF report for your doctor.[1][2][3][4]
Smart Home Integration: It features built-in IFTTT support , meaning you can program your bedroom lights to dim when you get into bed or have your smart thermostat adjust when you get up.[1][2]
If you're looking into mats because you dislike wearables, would you also be open to considering smart rings or smart bands , or do you specifically need a contactless, under-mattress solution?
