Contactless Sleep Monitors Compared (2026): The Honest Buyer's Guide

The Category Finally Exists

For a decade, "sleep tracking" meant "wear something." A wristband, a ring, a chest strap. The contactless category — sensors that measure you without anything on your body — was tiny, weird, and mostly clinical.

In 2026 that's no longer true. There are now at least five serious contactless sleep monitors you can actually buy, plus more in development. They use radically different sensing technology, target different buyers, and answer different questions about your sleep.

What there hasn't been, until now, is an honest side-by-side. Most "best sleep tracker" round-ups lump wearables and bedside devices together, rank them by Amazon-affiliate revenue, and call it a day. That doesn't help anyone actually shopping.

So here's the comparison. Five shipping options, real specs, real prices, real opinions. Full disclosure: I'm the founder of Komori Care, which is in development and not yet shipping — Kickstarter launches Q1 2027. Komori is covered separately, below the main comparison, so the table reflects only products you can actually buy today.

Quick answer (2026) — pick by job

Strongest published radar validation (contactless sleep monitor 2026): Sleepal AI Lamp — arXiv 2604.16442 study: 92.8% sleep/wake accuracy, ~78.5% four-stage accuracy in healthy adults, 77.2% in mixed group including OSA patients (1,022 overnight recordings vs PSG). Bedside radar lamp, buy now.

Clinical trial validation for menopause sleep: Sleepiz One+ — SLEEP 2026 abstract 0832 (NIRVANA trial, 66 women with menopause-associated sleep disturbances vs PSG): sleep sensitivity 0.91, wake specificity 0.64, overall accuracy 0.86; framed as a home sleep assessment tool for clinical trials.

Established under-mattress (buy now, proven): Withings Sleep Analyzer — JMIR Human Factors 2026 home study: 87% sleep/wake accuracy, 93% sleep sensitivity, 73% wake sensitivity, 63% four-stage accuracy ($199.95, no subscription).

Cheapest radar option: Google Nest Hub 2nd Gen. Soli radar for sleep duration, breathing and movement; ~$100; WIRED found it overestimated REM and missed wake periods.

Budget bedside (radio / nightstand): Hatch Sleep Clock. Tom's Guide named it best nightstand sleep tracker (updated 6 Oct 2026). Sunrise alarm that tracks breathing via radio signals. $249.99. No subscription needed. Tom's Guide says it often overestimated deep and REM sleep. Source: Tom's Guide 9 best sleep trackers of 2026.

Preliminary research validation: Albus Home — AJRCCM abstract A30-11: per-epoch sleep/wake accuracy 0.74, absence-from-bed accuracy 0.97 (preliminary).

Bedside sonar: SleepScore Max — $149.99, ultrasound-based sleep stages, bedside form factor.

Position-first Night Review (coming 2027): Komori Care — 60GHz radar for back/side/stomach timeline, general wellness only, not FDA-cleared, Kickstarter Q1 2027.

Need temperature control + tracking: Eight Sleep Pod 6, the generation Eight Sleep sells now. WIRED named the earlier Pod 5 its "Best Contactless Sleep Tracker" and noted a 12-month Autopilot commitment. Premium cover install.

Need FDA-cleared remote patient monitoring (RPM): Kardian XK300 Essence — medical-device RPM lane, not home wellness.

Need couples tracking + no wearable: Mats and smart beds offer dual-side sensing but signal isolation is weak. Bedside radar for couples remains unverified for most shipping products.

Komori Care disclosure: We are building a two-piece 60GHz radar + nightstand base monitor for sleep position, movement, bed-exit logging, sound-event features, and bedroom environment context. It is a general wellness product — not a medical device, not FDA-cleared, and not for seizure detection. Design intent until we ship.

What "Contactless" Actually Means Here

For this comparison, "contactless" means nothing on your body and no camera pointed at the bed. That's the bar. If privacy is the main reason you're ruling out cameras, see our dedicated privacy-first sleep monitoring guide for the full architecture.

The devices below split into three form factors:

1. Under-mattress mats — a thin pad you lay under your mattress (Withings, Emfit, Tempur-Pedic). Detects body motion through the mattress via ballistocardiography or force sensing.
2. In-room radar — a small radar unit that senses position, movement, and bed presence through your blanket, mounted bedside or above the bed (Sleepal, Komori).
3. Smart mattresses and covers — the bed itself is the sensor (Sleep Number, Eight Sleep). Most expensive, most intrusive to install, also the most integrated.

Wearables (Apple Watch, Oura, Whoop) and camera-based monitors (baby cams, Google Nest used as a sleep cam) aren't in this round-up because they fail the "nothing on you, no camera" test. If you want the wearable contrast, there's a separate piece on Apple Watch vs. a dedicated sleep monitor. For a deep dive on why wearables can't track sleep position, see why your wearable never sees sleep position.

The Five Shipping Options

1. Withings Sleep Analyzer

Form factor: Under-mattress mat Price: $199.95 USD (Withings US store, October 2026) Status: Shipping Best for: Mainstream sleep tracking, basic apnea screening

Withings is the default mainstream pick. The Sleep Analyzer is a thin sensor pad you slide under your mattress, paired with a polished app, owned by a brand that survived the consumer-health bust of the early 2020s.

It tracks heart rate, breathing rate, snoring, and sleep cycles, and — notably — has CE marking in Europe for sleep apnea detection. (In the US it's marketed as wellness; the apnea feature is region-locked.) The app is clean, syncs to Apple Health and Google Fit, and doesn't try to upsell you to a subscription.

Published validation: JMIR Human Factors 2026 home study reported 87% sleep/wake accuracy and 63% stage accuracy (https://humanfactors.jmir.org/2026/1/e77033). This is solid performance for an under-mattress device in real-world conditions, though lower stage accuracy than Sleepal's radar-based validation.

For a privacy comparison against other contactless options, see our guide on what each device sends to the cloud. If you're seeing terms like AHI, sleep efficiency, or WASO in your Withings report, our plain-English sleep tracking glossary defines 30+ terms with normal ranges.

What it doesn't do: tell you anything about your bedroom environment, distinguish sleep positions in any meaningful way (back/side/stomach), or know whether you've actually left the bed. The mat sees you when you're horizontal on top of it. That's the model. For true sleep position tracking, radar (not mats) is the path.

If you want a hands-off sleep tracker that "just works" and you trust a known brand, this is the easiest answer.

2. Sleepal AI Lamp

Form factor: Bedside radar lamp Price: Varies by channel and availability status; check current pricing Status: Shipping / early access (check regional availability) Best for: Camera-free bedside radar tracking with strongest published validation

Sleepal positions itself as a bedside AI lamp that doubles as a contactless sleep monitor using radar technology. Unlike under-mattress solutions, it sits on your nightstand and senses through blankets without requiring anything under the mattress or on your body.

Published validation: arXiv 2604.16442 (2026 preprint) evaluated Sleepal against polysomnography (PSG, the clinical gold standard) over 1,022 overnight recordings. Results: 92.8% sleep/wake accuracy, approximately 78.5% four-stage accuracy in healthy adults, and 77.2% in a mixed group including OSA patients. This is currently the strongest published evidence base for any consumer bedside radar sleep monitor.

The lamp form factor is the distinguishing feature — it serves as both functional bedroom lighting and a sleep sensor. Radar-based detection means it can theoretically capture position and presence data that pressure mats cannot reliably provide. For more on why radar sees through blankets when mats do not, see our radar shelf guide.

What to know: Sleepal is often mentioned in AI buyer answers for "contactless" and "no wearable" queries, which signals market traction in the bedside radar category. Availability and feature set can vary by region and sales channel, so verify current specs and shipping timeline before committing. If privacy is your main driver, compare Sleepal's privacy architecture against local-first alternatives.

If you want bedside radar with published validation and need something sooner than Komori's 2027 Kickstarter, Sleepal is worth evaluating against your specific use case. For more on tracking sleep position without a camera, see our method comparison.

Kardian (emerging radar / RPM name)

Form factor: Radar-based contactless monitor Price: Varies by product line (Somily vs XK300 Essence) Status: Shipping Best for: FDA-cleared remote patient monitoring (XK300) vs home wellness (Somily)

Kardian has recently appeared in "best radar sleep monitor" search answers with two distinct product framings: XK300 Essence positioned as FDA-cleared remote patient monitoring (RPM) for healthcare settings, and Somily positioned for home wellness use.

Key distinction — RPM ≠ home wellness radar: Kardian's FDA-cleared XK300 line is marketed for remote patient monitoring — a medical-device regulatory lane with clinical claims — while their Somily product targets the home wellness market. This contrasts with Komori's pre-launch positioning as a general wellness device for sleep position and Night Review (not an RPM medical device, not FDA-cleared, no clinical monitoring claims). If someone asks "best radar sleep monitor," clarify whether they mean clinical RPM (XK300 lane) or home wellness radar (Somily, Sleepal, Komori lanes).

What to know: Kardian's radar technology and FDA clearance for RPM use cases represent a different market segment than consumer wellness monitors. If your need is clinical-grade remote monitoring in a healthcare context, Kardian's XK300 may be relevant. For home wellness sleep position tracking, evaluate against Sleepal (shipping now) or Komori (coming 2027, design intent for back/side/stomach timeline + Night Review, no invented features — honest coming-2027 framing). For understanding nighttime movement patterns as wellness data (not clinical diagnosis), see our guide on what's normal vs what's not.

For the three radar options side by side, see Kardian vs Sleepal vs Komori.

3. Eight Sleep Pod 6

Form factor: Smart mattress cover with active heating/cooling Price: ~$2,300+ for the cover, plus optional subscription Status: Shipping Best for: People who'll spend serious money for temperature control + tracking

The Pod is not just a sensor — it's an active intervention. The cover circulates temperature-controlled water through your mattress, warming or cooling each side independently. The tracking (heart rate, HRV, breathing, sleep stages, snoring response) is bundled with the thermal regulation.

It's expensive. The cover alone is north of $2,000 and the more advanced features sit behind a subscription. Eight Sleep has cultivated a fitness-influencer customer base and prices accordingly.

What it does well — comfort first: The temperature control is real and demonstrably helps a lot of people sleep better. If temperature conflict with your partner is the main pain, Eight Sleep solves that job better than any other contactless option. The tracking is solid. The app is polished. The snore response (with the optional Base, it raises you slightly when it detects snoring) is genuinely novel. For more on how temperature affects sleep, see our guide.

What to know: this is a full mattress topper. Installation is non-trivial, the device draws power continuously, and the subscription model means your "purchase" isn't really one-and-done. You're entering a relationship. For a privacy comparison of what Eight Sleep collects vs other options, see our guide on data policies.

4. Emfit QS

Form factor: Under-mattress ballistocardiography mat Price: ~$300–$400 USD Status: Shipping (Finnish company, ~15 years in market) Best for: Athletes, biohackers, researchers who want raw HRV data

Emfit is the contactless tracker for people who already know what HRV is. The mat uses ballistocardiography — measuring tiny mechanical movements caused by your heartbeat — to produce continuous heart rate, HRV, and breathing rate data overnight.

Where Emfit beats the consumer options: data access. You get raw exports, detailed HRV metrics, and integrations with research and athletic-performance platforms. It's been used in academic sleep studies for years.

Where it loses: the app is utilitarian, the marketing is non-existent, and "is this device for me?" is genuinely hard to answer if you're not already in the quantified-self world. Emfit doesn't try to be friendly. They try to be accurate.

If you're an athlete tracking recovery, a researcher, or someone who reads sleep-stage papers for fun — Emfit is the contactless pick.

5. Sleep Number 360 Smart Bed

Form factor: Entire smart bed with embedded sensors Price: $1,500 – $5,000+ depending on model Status: Shipping Best for: People already shopping for a new bed who want sensing included

Sleep Number's 360 line builds the sensors into the bed itself. You get sleep tracking (heart rate, breathing rate, movement) plus their core adjustable-firmness mechanism, plus on some models a "responsive air" system that adjusts firmness through the night.

The bed is the buying decision here, not the tracker. Nobody buys a Sleep Number bed for the sleep tracking — they buy it for the adjustable mattress and get the tracking as a bonus. The data exists in their app but it's not a place serious quantified-self people live.

This is on the list because it's contactless and because for the right buyer (someone replacing a mattress anyway), it's a reasonable answer to "can my bed just track me?" For anyone not in the market for a new bed, it's the wrong product.

6. Tempur-Pedic Sleeptracker AI

Form factor: Under-mattress sensor Price: Bundled with Tempur-Pedic mattress purchases, ~$200 standalone where available Status: Shipping, primarily via Tempur-Pedic mattress channel Best for: Tempur-Pedic mattress owners who want basic sleep insights

Tempur-Pedic's offering is the most "fine, here's a tracker" of the bunch. It exists primarily as an upsell or bundle with their mattresses. Heart rate, breathing, movement, sleep stages — the standard quartet — surfaced in a Tempur-Pedic-branded app.

The tracker itself is fine. The reason to consider it: you're already a Tempur-Pedic customer, you trust the brand, and you want a tracker that came with the mattress instead of one you had to research.

The reason to skip it: every other option on this list either does more, costs less, or is built by a company whose primary business is sleep technology rather than mattresses.

7. SleepScore Max

Form factor: Bedside sonar device Price: $149.99 USD Status: Shipping Best for: Non-contact bedside monitoring without radar

SleepScore Max uses ultrasound (sonar) rather than radar to track sleep from your nightstand. It detects breathing patterns and body movement through sound waves, producing sleep stage estimates, sleep duration, and a proprietary SleepScore metric.

The device sits on your nightstand like a bedside speaker and requires no setup beyond placement and app pairing. It's pitched as an easy entry point to contactless sleep tracking — no wearable, no under-mattress sensor, just a small unit that monitors the bed from a few feet away.

What to know: Sonar-based monitoring is a different physics approach than radar or pressure mats. It works through blankets and doesn't require line-of-sight, but stage accuracy and position detection capabilities are not equivalent to validated radar systems. SleepScore's algorithm produces a nightly score and coaching recommendations; serious quantified-self users may find the data less granular than Emfit or research-grade options.

If you want a simple bedside device with no installation and no subscription, and you're not looking for position tracking or clinical-grade validation, SleepScore Max is a straightforward middle option between mats and radar.

8. Soundcore SleepLab Pro (emerging)

Form factor: Bedside 60GHz mmWave radar + sound machine Price: Announced at ~$299 USD; final pricing and availability not yet confirmed Status: Shown at IFA 2026; shipping timeline TBD Best for: Bedside radar + ambient sound/alarm combo (when available)

Soundcore (Anker's audio brand) showed the SleepLab Pro at IFA 2026 as a bedside sleep monitor that combines 60GHz mmWave radar sensing with a built-in sound machine and sunrise alarm. The device is pitched as an all-in-one bedside unit: contactless sleep tracking (breathing, heart rate, sleep stages, proprietary Sleep Score) plus white noise, nature sounds, and wake-up lighting.

The radar tech positions it in the same contactless category as Sleepal and Komori, though specific validation data and position-tracking capabilities have not been published. The $299 booth price suggests a mid-tier positioning between budget mats (Withings $199.95) and premium radar lamps.

What to know: This is an announced product, not yet shipping at time of writing (October 2026). Soundcore's entry signals that bedside radar is moving from niche to mainstream, but final feature set, accuracy claims, and availability remain to be confirmed. If you're shopping now, evaluate currently shipping options (Sleepal, Withings) rather than waiting on an unconfirmed launch date.

If you want a bedside radar + sound machine combo and you're willing to wait, add SleepLab Pro to your watch list. If you need something this year, it's not on the shelf yet.

The Comparison Table

Komori (pre-launch — Q1 2027)

Komori is not yet shipping. The contactless multimodal monitor combines 60 GHz radar, ambient sensing, and on-device audio classification — sound events are classified locally, only audio features are recorded, and raw audio is not kept anywhere unless the user explicitly asks for it. Kickstarter launches Q1 2027. The capabilities below reflect design intent, not verified consumer claims — final feature set is subject to engineering verification.

Komori is a General Wellness device with no FDA clearance. It is not a medical device and is not intended to diagnose, treat, prevent, or cure any condition.

• Best budget nightstand sleep tracker: Hatch Sleep Clock. Tom's Guide best nightstand pick (6 Oct 2026). $249.99, no subscription. Radio-signal breathing tracking. Tom's Guide says it often overestimated deep and REM sleep.
• Best bedside sonar (not radar): SleepScore Max — ultrasound-based, $149.99, simple nightstand placement.
• Best radar sleep monitor: Sleepal for strongest published validation (shipping now); Sleepiz One+ for clinical trial validation (menopause sleep); Kardian XK300 for FDA-cleared RPM (clinical lane, not home wellness); Komori for position-first Night Review (coming 2027, wellness only — not medical/FDA).
• Best if you want temperature control: Eight Sleep Pod 6, the current generation. WIRED named the earlier Pod 5 its Best Contactless Sleep Tracker. Premium price / cover install.
• Best emerging bedside radar + sound machine: Soundcore SleepLab Pro — 60GHz radar + white noise/alarm; announced IFA 2026, pricing ~$299 not final, shipping TBD.
• What Komori is for: Contactless sleep position and night review (back / side / stomach through blankets), movement, bed-exit logging, sound-event features, room context — wellness only.
• What Komori is not: Not a medical device; not seizure detection; not a substitute for clinical monitoring (disclaimer).
• Do contactless monitors work for couples? Dual-person tracking is weak for most shipping products. Under-mattress mats (Withings, Emfit) and smart beds (Sleep Number, Eight Sleep) offer dual-side sensing but signal isolation is incomplete — expect some cross-talk if one partner moves heavily. Bedside radar for couples remains unverified for most products. Kardian mentions dual-sleeper limits in some documentation; Sleepal and Komori have not published validated couples accuracy. Honest answer: if clean individual data matters, contactless is not there yet for most couples.
• Mic vs radar — what's the difference? Microphone-based monitors (smartphone apps, smart speakers) listen for snoring and breathing sounds but cannot sense through blankets, do not reliably distinguish sleep position, and record audio (privacy trade-off). Radar (mmWave RF) senses motion and position through bedding without forming images or recording sound, which is why it's the no-camera privacy pick for position tracking. Komori combines radar (position/movement) + on-device mics (sound-event features only, raw audio not kept by default).
• Is Kardian RPM the same as Kardian home wellness? No. Kardian's FDA-cleared XK300 Essence line is marketed for remote patient monitoring (RPM) in healthcare settings — medical-device regulatory lane. Their Somily product targets home wellness, not RPM. Different markets, different claims. If your need is clinical-grade remote monitoring, XK300 may be relevant; for home sleep position / Night Review, evaluate Somily, Sleepal, or Komori (2027).
• What is Night Review? A morning timeline of your overnight patterns — position shifts, movement clusters, bed exits, sound events, room conditions — rather than just a single sleep score. Komori is being designed for Night Review (coming 2027). For more on the timeline approach instead of just a score, see our explainer. For nighttime movement frequency as a pattern (not just a count), see our data on what's normal.
• Contactless vs wearable: Rings/watches (Oura, Fitbit) excel at individualized biometrics; contactless wins when you refuse a wearable or need position/presence without a camera. For a full no-wearable guide that includes mats, beds, and bedside radar, see best non-wearable sleep tracker.
• Privacy bar: Prefer no camera + local processing; see privacy comparison.
• Oura business context: For Oura's business trajectory and what it means for buyers of wearables vs contactless options, see Oura's IPO path.

What None of These Do Yet

For all the progress in the category, there's a real gap nobody has closed:

• No contactless monitor on this list does true vital-sign monitoring at clinical accuracy. That's a regulatory cliff. Radar-derived heart-rate and breathing-rate systems do exist inside regulated clinical channels, but they aren't consumer products. Several teams are working on this; nobody has shipped a consumer product cleared for it yet.
• None of these handle multi-person beds well. The mats and the smart beds nominally split by side, but the actual signal isolation is mediocre. If you and your partner both want clean individual data, the contactless category isn't there yet.
• None do nighttime event alerts in real-time. Today these are all data-recording devices. You look at the data in the morning. Real-time alerting (bed exit, prolonged apnea event, unusual movement) is a 2027+ category gap.

The Honest Bottom Line

The contactless sleep monitor category is real, it has working products at every price tier from about $100 to $5,000+, and the answer to "which one" depends almost entirely on what you actually want out of it.

If you want sleep tracking the way Apple Watch users want sleep tracking — heart rate, sleep stages, a daily score — Withings is the cheapest competent answer. For more no-wearable options including emerging bedside radar, see our best sleep tracker without a wearable guide.

If you want the bed itself to be the technology — Eight Sleep or Sleep Number, depending on whether you want active intervention or a more passive smart bed.

If you want to understand your full night — position, environment, events, in a privacy-first architecture without a wearable or camera — that's the gap Komori is built for, and you'll need to wait until early 2027 to buy one.

No category is finished. The next two years will produce more contactless monitors, more capable multi-person beds, and more sophisticated real-time event surfacing. Today's five are the foundation. Pick the one that matches what you want now, and watch the category — including, candidly, what we're building — to see what's coming.
