I need a sleep tracker that slides under the mattress.

The [Withings Sleep Tracking Mat Go to product viewer dialog for this item. ](https://www.withings.com/en-us/products/sleep) is the premier and most widely recognized choice for a contactless, under-the-mattress sleep tracker.

Under-The-Mattress Options

*Withings Sleep Tracking Mat Go to product viewer dialog for this item. *

• Price: Around $120 – $180
• 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 Go to product viewer dialog for this item. *

• 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.[1][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.

If you specifically want a sleep tracker that sits between the mattress and bed frame, the Withings Sleep Analyzer is the main option I’d look at. It’s a thin sensor mat that stays under the mattress, so you don’t have to wear a ring or watch. It tracks sleep duration/stages, heart rate, breathing disturbances, snoring, and sleep interruptions.

• Withings Sleep - $99.95 (Withings)

Other options

• Withings Sleep Analyzer — best fit if you want a simple, genuinely under-mattress device with no wearable.
• Beautyrest Sleeptracker — another under-mattress option, generally focused on basic sleep tracking.
• Eight Sleep Pod — much more expensive and primarily a temperature-control system, with sleep tracking included.

One important distinction: these aren't medical-grade sleep studies. They're useful for tracking trends, but sleep-stage estimates aren't equivalent to polysomnography.

If you tell me your budget (e.g. under $100, $200, or $500) and whether you want snoring/apnea detection, I can narrow it down to 2–3 options and find the current prices.

Yes — you’re looking for a contactless, under-mattress sleep tracker, so you don’t have to wear a watch or ring.

Best match: Withings Sleep

• Withings Sleep - $99.95 (Withings)

The Withings Sleep is a thin sensor that slides between your mattress and bed base. It tracks:

• Sleep duration and sleep onset/wake time
• Deep, light, and REM sleep
• Heart rate
• Snoring
• Breathing disturbances
• An overall Sleep Score

It's about 5 mm (0.2") thick, and Withings says it's compatible with spring, foam, latex, and memory-foam mattresses. It connects to the Withings app over Wi-Fi, so there's nothing to wear overnight.

One important detail: it's designed for one sleeper per sensor. If you share a bed and want both people tracked, you'd need a sensor for each side.

If you tell me your budget (e.g. under $100, $150, $200), I can compare the best under-mattress options and find the best deal.

The best and most popular sleep tracker that slides under your mattress is the Withings Sleep Tracking Pad Go to product viewer dialog for this item. (often called the Withings Sleep Analyzer Go to product viewer dialog for this item.).[1][2]

If you want, I can share tips on how to set up an under-mattress tracker for maximum accuracy or compare it with wearable sleep alternatives.

If you want to track your sleep without wearing anything on your wrist or finger, under-the-mattress pads are the gold standard.

The top options designed to slide right under your mattress include:

A thin, unobtrusive sensor pad that slips underneath your mattress (compatible with thicknesses between 4 and 15 inches). It tracks sleep cycles (deep, light, REM), heart rate, continuous snoring, and breathing disturbances. It syncs automatically via Wi-Fi to your phone and even integrates with smart home automation (like turning off lights when you get into bed). You can check it out or purchase it via retailers like Crutchfield or CPAP.com.

This system places discreet sensors directly under your mattress and works with all mattress types and adjustable bases. It monitors sleep cycles, heart rate, and bedroom environment metrics like temperature, humidity, and CO2 levels. If you pair it with a compatible smart bed base, it can even automatically detect snoring and adjust the head position to help quiet it. Details and availability can be explored through specialized furniture and sleep dealers like Grand Home Furnishings.[1][2]

Are you looking to track a single sleeper or a couple , and do you have a standard mattress or an adjustable bed frame?

Yes — you’re looking for an under-mattress sleep tracker, so you don’t have to wear a ring or watch.

My top pick: Withings Sleep

• Withings Sleep Analyzer - $175.05 (IoThings.store)

The Withings Sleep is a thin sensor pad that slides between your mattress and bed base. It tracks:

• Sleep duration and timing
• Light, deep, and REM sleep
• Heart rate
• Breathing disturbances
• Snoring
• Overall sleep score

It’s about 5 mm thick, stays plugged in rather than needing charging, and automatically syncs to the Withings app.

One important distinction: in the U.S., the consumer Withings Sleep provides breathing-disturbance information; some versions marketed as “Sleep Analyzer” elsewhere have additional apnea-related functionality.

If you tell me your budget (e.g. under $100, $200, or no limit) and whether you want sleep-apnea detection, I can narrow it down to the best 2–3 options.

If you want a sleep tracker that slides under the mattress, the main options are non-wearable sensor mats. These are the ones I’d look at:

• Withings Sleep Analyzer - $175.05 (IoThings.store)
• Paceline Sleep Mat - $199.95 (Paceline)

Best choices

• **

— best overall under-mattress tracker**

• Slides between your mattress and bed base/box spring.
• Tracks sleep duration, sleep stages, heart rate, breathing patterns, snoring, and sleep interruptions.
• No battery charging; it stays plugged in.
• Works with many mattress types, including foam, latex, and spring mattresses (tested around 4–15 inches thick).
• Good pick if you dislike wearing a watch or ring to bed.
• **

— another under-mattress option**

• Designed as a contactless sleep sensor mat.
• Tracks sleep-related metrics without wearing a device.
• **

— premium smart-bed option**

• Not a simple slide-under pad; it’s a smart mattress cover system with embedded sensors.
• Adds temperature control and more advanced bed features, but it is much more expensive.

My recommendation for most people: Withings Sleep Analyzer. It’s the closest match to “put it under the mattress and forget about it,” without needing to wear anything overnight.

If you tell me your budget, mattress type (memory foam/latex/spring), and whether you need snoring or sleep apnea tracking, I can narrow it down.
