Our verdict
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
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.
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.
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) may provide more cushioning for side sleepers.
Back Sleepers
The Sleep Number ClimateCool's listed firmness of 5/10 may suit back sleepers seeking a medium-to-firm surface. Spinal alignment and hip support have not been objectively measured for this model unless documented test results appear above.
Stomach Sleepers
At 5/10 firmness, the Sleep Number ClimateCool may be too soft for stomach sleepers. Stomach sleepers may want to compare a firmer model, especially if they notice uncomfortable hip sinkage.
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.

Read the full Sleep Number ClimateCool vs. Tempur-Pedic LuxeBreeze comparison →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.

Construction & Materials Review
We document the mattress's published layer construction, materials, densities and cover fabrics from manufacturer specifications and supporting documentation.
Specification & Certification Verification
We check published specifications, certifications and material claims against the manufacturer's own documentation, and flag anything we cannot confirm.
Policy & Price Verification
