Latest smart mattresses with built-in sleep tracking compared

Our top picks at a glance

Here is how our three picks compare. Each name links to its full write-up further down the page.

Prices last checked October 13, 2026 and may change. Ratings reflect our own testing and research. Eight Sleep prices are for the Standard Pod 6; membership is required and priced separately.

How built-in sleep tracking actually works

A mattress cannot measure your pulse the way a watch does, so smart beds listen to your body instead. The main technique is ballistocardiography: ultra-sensitive sensors in the mattress or cover detect the tiny mechanical vibrations each heartbeat sends through the body. From those vibrations, software derives heart rate, heart-rate variability, respiratory rate, and movement — enough to estimate sleep stages, sleep onset, and wake-ups with reasonable accuracy.

Sleep Number takes a different route with its air-chamber design. The 360 smart beds measure pressure changes inside the air chambers on each side of the bed, using those fluctuations to track average heart rate, average breathing rate, and body motion. Its SleepIQ system then converts that data into sleep scores and, more interestingly, automatic responses: the bed can adjust firmness overnight and, on the Climate models, run active cooling or warming per side.

Eight Sleep's approach is the most sensor-dense. The Pod is a fitted cover with a water-circulation system woven through it — the same system that heats and cools each side independently — plus biometric sensors that track heart rate, HRV, respiratory rate, sleep stages, and even snoring. Its Autopilot software uses that data in real time: cooling you down as you fall asleep, warming you slightly before your alarm, elevating the head when it detects snoring, and playing white noise through the base. It is less a tracker and more a closed loop — measure, respond, measure again.

Tempur-Pedic is the odd one out, and we include it deliberately. The TEMPUR-Adapt mattress itself contains no sleep-tracking sensors; it is a pressure-relieving memory foam (or hybrid) mattress, full stop. Tracking enters the picture only if you pair it with the TEMPUR-Ergo smart base, which includes Sleeptracker-AI sensors in the base. That honesty matters: if "built-in sleep tracking" is your requirement, the Adapt qualifies only as part of a system — which is exactly how we have rated it.

What to check before buying a smart mattress

The sticker price is only the opening bid. Run through these checks before you commit — they are where smart-mattress purchases most often go wrong.

• Price: add the membership to the mattress. Eight Sleep's Pod 6 requires an Autopilot membership from $17/month or $199/year — over five years that adds roughly $1,000 to the $2,899 Queen price. Sleep Number's Climate360 includes its tracking with no subscription. A budget mattress under $300 plus a wearable can do 80 percent of the job for a tenth of the money, so be honest about what you are buying.
• Tracking depth: decide what data you actually want. If you want sleep stages, HRV trends, and respiratory rate, you need Eight Sleep or Sleep Number. If you mainly want to know how long you slept, a far cheaper setup works — see our guide to the best sleep trackers without a subscription.
• Trial period: smart mattresses need longer trials than ordinary ones because the learning curve is real — the software needs weeks to calibrate to you. Sleep Number offers 100 nights; Tempur-Pedic offers 90; Eight Sleep offers 30 nights on the Pod, which is short for the price, so read the terms carefully.
• Warranty and returns: at these prices, the warranty is part of the product. Eight Sleep ties its warranty to the membership tier (2 years on Standard, 5 on Enhanced and Elite); Sleep Number offers a 15-year mattress warranty; Tempur-Pedic offers 10 years. Note who pays for return shipping and whether there are restocking or return fees — Sleep Number charges a $250 return fee on some models.
• Compatibility: the Eight Sleep Pod is a cover that fits over your existing mattress, so check your mattress size and type first. The Climate360 is a complete bed with its own smart adjustable base. The TEMPUR-Adapt needs the TEMPUR-Ergo base for tracking, and split-king setups add configuration complexity everywhere.

Eight Sleep's newest cover starts at $1,999 for the Solo size — but every Pod requires an Autopilot membership, so the sticker price is never the whole price.

Matching the mattress to how you sleep

Tracking is only half the product; you still have to sleep on the thing. Hot sleepers should weight the cooling side of the decision heavily — Eight Sleep's active water cooling and the Climate360's per-side climate control are in a different league from passive cooling foams, as our memory foam vs. hybrid comparison for hot sleepers explains. If pressure relief is your priority, the TEMPUR-Adapt's dense TEMPUR material remains the benchmark, and our best mattresses for back pain under $500 shows how far non-smart options go on comfort alone.

Our picks in detail

Each pick below includes a one-line verdict, the current price, and the main pros and cons from our testing and research.

Best overall

Eight Sleep Pod 6

4.5/5

The deepest sleep tracking you can buy — plus active per-side cooling and heating on the mattress you already own.

$2,899 Queen, at time of writing — Autopilot membership from $199/yr required

Pros

• Active water-based cooling and heating per side — the real fix for hot sleepers, not just breathable foam
• Tracks heart rate, HRV, respiratory rate, sleep stages and snoring, then acts on the data: temperature shifts, elevation, white noise
• Fits over your existing mattress, so you keep the comfort you like and add the tech on top

Cons

• Every Pod requires a paid Autopilot membership — add ~$1,000 over five years to the sticker price
• Only a 30-night trial, short for a purchase this expensive; water unit adds noise and bulk beside the bed

Best luxury

Sleep Number Climate360

4.4/5

A complete luxury smart bed: per-side climate control, adjustable firmness, and a smart base included in the price.

$9,999 Queen, includes smart adjustable base, at time of writing

Pros

• Active per-side cooling and warming plus 20 firmness settings — the most personalized comfort in the category
• SleepIQ tracking (heart rate, breathing rate, motion) included with no subscription, tied to automatic adjustments
• Smart adjustable base with Partner Snore response, zero-gravity position and under-bed lighting included

Cons

• Five figures for a bed — the price of a used car, with a $250 return fee if it doesn't work out
• Air-chamber feel is not for everyone; foam and hybrid sleepers should try it in a store first

Best comfort

Tempur-Pedic TEMPUR-Adapt Medium Hybrid

4.6/5

The pressure-relief benchmark — superb comfort, but built-in tracking needs the TEMPUR-Ergo smart base add-on.

$2,299 Queen, currently $2,099 on tempurpedic.com, at time of writing

Pros

• Outstanding pressure relief and motion isolation from proprietary TEMPUR material plus 1,000+ coils in the hybrid
• No subscription, no app required — it is a mattress first, with 10-year warranty and 90-night trial
• Pairs with the TEMPUR-Ergo smart base for adjustable positioning and Sleeptracker-AI sleep data when you want the tech

Cons

• No built-in sleep tracking on the mattress itself — the "smart" part costs extra via the base
• Sleeps warmer than the active-cooling options above; hot sleepers should look at the Pod or Climate360

Do you still need a wearable?

For sleep data alone, a smart mattress largely replaces the wristband. Under-mattress sensors capture the same core metrics — sleep timing, stages, heart rate, respiratory rate — with the considerable advantage that there is nothing to wear, charge, or remember. Eight Sleep and Sleep Number both produce morning reports that stand up well against mid-range wearables, and neither asks you to sleep with plastic on your wrist.

The gap is daytime. A mattress knows nothing about your workout, your steps, or your stress through the afternoon. If your interest in sleep data is really an interest in recovery and training, the wearable still earns its place — the mattress covers the night, the band covers the day. For the wearable side of that equation, see our roundup of new sleep gadgets for 2026.

One more consideration: data ownership. Your nightly heart rate, respiratory patterns, and restlessness live in the mattress company's cloud — data that is valuable to them. Eight Sleep's tracking is inseparable from its paid membership; Sleep Number's is included but still lives in their ecosystem. Read the privacy policy with the same care you read the trial terms.

The honest costs

Smart mattresses are sold on monthly-payment math, so do the total-cost math instead. A Queen Eight Sleep Pod 6 at $2,899 with the Standard Autopilot membership at $199/year costs roughly $3,900 over five years — before any add-ons like the Blanket or Pillow Cover. The Sleep Number Climate360 at $9,999 with no subscription costs $9,999 over five years, full stop. The Tempur-Pedic TEMPUR-Adapt at $2,299 (currently $2,099) costs that and nothing more — but buys you no tracking at all.

None of these is a value purchase. A quality non-smart mattress plus a cooling topper and a subscription-free tracker delivers most of the measurable benefit for well under $1,000. What the smart beds buy you is automation: temperature that adjusts itself, firmness that responds to your body, snoring answered while you sleep. For hot sleepers who have tried everything else, the Pod's active cooling does something no passive product can. For everyone else, start cheaper and upgrade only if the data tells you to.
