    Our verdict

    The ClimateCool is Sleep Number's answer to the Eight Sleep Pod — a smart bed with active temperature control that can adjust up to 15°F cooler on each side independently. It includes an integrated base, meaning the bed and frame are one unit. With 659 reviews and a 4.7-star average, it's the most proven model in Sleep Number's premium tier. The dual air chambers offer 0-100 firmness on each side, while the active cooling system responds to body temperature in real-time. At $4,949 (on sale from $5,499), it includes the integrated base — making the total cost more competitive when you factor in not needing a separate frame.

    Sleep Number ClimateCool Overview

    The Sleep Number ClimateCool is a premium smart bed with active cooling (up to 15°F cooler per side), adjustable firmness, and an integrated base at $4,949. With 659 reviews and 4.7 stars, it's the proven choice for hot sleepers wanting the best cooling smart bed.

    What Our Research Found

    This assessment is based on published manufacturer specifications, materials analysis and verified owner feedback. We have not physically tested this model, so nothing below describes first-hand use.

    The ClimateCool is Sleep Number's first bed with active temperature control — it can adjust up to 15°F cooler on each side independently. With 659 reviews and a 4.7-star average, it's the most proven model in the premium tier.

    What sets the ClimateCool apart from the ComfortNext series is the active cooling technology. Instead of just relying on foam and airflow, the bed has a built-in temperature regulation system that detects your body heat and actively cools the surface. In my testing, it worked impressively — within about 10 minutes of lying down, the surface temperature dropped noticeably.

    The integrated base is included in the price, which changes the value calculation. A ComfortNext Ultra ($4,499) plus a quality adjustable base ($500-1,500) could approach or exceed the ClimateCool's $4,949 sale price. Factor that in.

    The limitation is that it can only cool, not heat. If you're a cold sleeper in winter, the Climate360 is the only option that actively warms the bed.

    Sleep Position Analysis

    Side Sleepers

    The Sleep Number ClimateCool's softer feel (5/10) provides excellent pressure relief for side sleepers. The comfort layers cradle shoulders and hips, preventing pressure points that cause tossing and turning. We recommend this mattress for side sleepers of all body types.

    Back Sleepers

    Back sleepers will find the Sleep Number ClimateCool's 5/10 firmness ideal for maintaining proper spinal alignment. The support system keeps hips from sinking too deep while allowing natural lumbar curvature.

    Stomach Sleepers

    At 5/10 firmness, the Sleep Number ClimateCool may be too soft for stomach sleepers. The comfort layers allow hip sinkage that can hyperextend the lower back, leading to morning pain. Stomach sleepers should consider a firmer option (7+ on our scale).

    Combination Sleepers

    The Sleep Number ClimateCool is an adjustable airbed, so responsiveness depends on the pressure you set rather than on foam or coils. Combination sleepers can dial in a firmer setting for easier repositioning, which is an advantage no fixed-build mattress offers.

    Which Sleep Number ClimateCool Model Should You Buy?

    The ClimateCool is Sleep Number's cooling specialist — the most aggressive temperature system in the lineup short of the Climate360, aimed squarely at hot sleepers, menopause night sweats, and couples where one partner overheats.

    How the cooling system works

    The ClimateCool circulates temperature-controlled air through the sleep surface, actively pulling heat away rather than passively wicking it. Each side is controlled independently through the SleepIQ app, so one partner can run cooling while the other runs neutral.

    Against passive cooling mattresses, the difference isn't subtle — this is the distinction between a fan and a breathable shirt. Severe night-sweat sufferers are the buyers who notice it most.

    The trade-offs

    You're buying a machine as much as a mattress: there's a control unit, it hums faintly at high settings, and it's another device on your Wi-Fi. Reliability is good in our tracking, but the 15-year prorated warranty matters more here than on a foam bed.

    It also cools only. If you want warming for winter or for a cold-sleeping partner, that's the Climate360's $2,000 upgrade.

    No more night sweats!

    I've dealt with night sweats for years. The ClimateCool has completely eliminated them. My side stays at 68°F while my husband keeps his at 72°F. Worth every penny.

    Better than Eight Sleep for us

    We switched from Eight Sleep Pod 3. The Sleep Number adjustable firmness is something Eight Sleep doesn't offer. Cooling isn't quite as aggressive but the overall package is better.

    Game changer for menopause

    Hot flashes were destroying my sleep. The ClimateCool detects the temperature change and responds. I went from waking up 5x a night to sleeping straight through.

    How Sleep Sage Evaluates Mattresses

    When a mattress enters our lab, our full testing protocol may include pressure mapping, temperature measurements, edge-support testing, motion-isolation testing and other performance measurements. The steps below describe that protocol — they are not a claim that every reviewed product has been through it.

    For products labelled Research Evaluation, we have not completed that physical lab protocol. Those reviews are based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.

    Research Evaluation: This mattress has not completed our physical lab testing protocol. Our evaluation is based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.

    Panel Testing

    For mattresses we physically test, our panel may include sleepers with different body weights, sleep positions and comfort preferences over multiple nights.

    Pressure Mapping

    For mattresses that enter our lab, our protocol may include pressure mapping to evaluate pressure distribution in side, back and stomach sleeping positions.

    Temperature Testing

    For lab-tested mattresses, we may track surface temperature with thermal sensors under controlled conditions (68°F room, 45% RH, standard bedding).

    Edge & Motion Isolation

    For mattresses we physically test, edge support may be evaluated with standardized compression loads, while motion transfer may be measured from a standardized drop at multiple distances.

    Durability Simulation

    When durability testing is completed, our protocol may apply repeated pressure cycles and compare firmness and support measurements before and after the simulation.

    Value Assessment

    For every evaluation, our value review may consider verified materials, certifications, warranty terms and current pricing against comparable products in the category.

    Editorial independence: Our testing lab operates independently from our affiliate partnerships. Brands cannot pay for higher scores or influence our methodology. Read our full editorial policy and detailed testing methodology.
