This guide reviews published product and support information. It is not a new instrumented test, and no smart bed can guarantee uninterrupted sleep. The exact features, sizes and prices should be confirmed with Sleep Number before purchase.
What ClimateCool does—and does not do
Sleep Number describes ClimateCool as an actively cooling bed with adjustable comfort on each side. Its Climate Collection guide distinguishes it from Climate360, which offers active core warming as well as cooling. Do not assume ClimateCool independently warms one sleeper’s core while cooling the other.
SmartTemp programs let eligible owners schedule temperature settings in the Sleep Number app; the company says each sleeper can manage their own program. The same guidance lists core cooling for ClimateCool and Climate360, while core warming is listed for Climate360. Foot warming depends on the applicable model or compatible base. Confirm the features and controls included in your particular purchase.
Cooling is not a substitute for a comfortable room, suitable bedding or medical care for persistent night sweats. Personal response varies with the room and bedding, and the cooling equipment requires power.
Adjustable firmness and sleep tracking
Sleep Number’s adjustable air system lets sleepers select a firmness setting; a higher Sleep Number setting is firmer. The company says most of its beds provide dual-side adjustment, but check the exact size and configuration. Its Responsive Air guidance says the system can make pressure adjustments to help maintain the chosen setting. That feature adjusts air pressure; it is distinct from temperature control.
Sleep Number lists app-based sleep tracking for the Climate collection. Tracking can help you notice patterns, but consumer sleep data and scores are estimates, not a diagnosis of sleep apnea or other sleep disorders. Ask which functions need an app, internet connection or account and what happens if the connection is unavailable.
ClimateCool vs. Climate360
| Feature | ClimateCool | Climate360 |
|---|---|---|
| Temperature | Active core cooling | Active core cooling and warming |
| Comfort | Adjustable air support; check size configuration | Adjustable air support; check size configuration |
| App features | Climate collection tracking and eligible temperature programs | Climate collection tracking and eligible temperature programs |
| Best comparison point | Cooling is the primary need | Core warming is also a priority |
Both are more complex than a conventional mattress. Compare the actual package—including base, installation, delivery and any accessories—rather than only the mattress headline price. See Sleep Number’s current Climate collection for available models.
What to check before buying
- Try the feel. Adjust both sides and lie in your usual sleep positions. Cooling and firmness are separate decisions.
- Confirm the package. Ask which base and controls are included, whether the base articulates, and whether foot warming costs extra.
- Check the logistics. Measure the room, doorways and electrical access; ask about delivery, setup and removal of the old bed.
- Read trial and warranty terms. Check the eligible items, required adjustment period, return or pickup costs, and coverage for the mattress, base and electronics separately.
- Ask about service. Understand repair procedures, replacement parts and what works during a power or connectivity outage.
Sleep Number’s bed-buying guide describes its mattress trial, but policies and exclusions can change. Read the terms attached to your order, especially for bases and accessories.
Common questions
Does ClimateCool heat and cool the mattress?
Sleep Number describes ClimateCool as actively cooling. It identifies active core warming as a Climate360 feature; separate foot-warming options depend on the base or model.
Can partners use different settings?
Sleep Number says each side can be adjusted and each sleeper can manage a temperature program on eligible configurations. Confirm the capabilities of the size and package you are considering.
Is sleep tracking medical grade?
Do not use a consumer sleep score to diagnose or rule out a medical condition. Discuss persistent sleep problems with a qualified clinician.
