Sleep Number Climate Cool

What Is the Sleep Number Climate Cool?

The Sleep Number Climate Cool is an integrated smart bed system that combines Sleep Number's signature adjustable air firmness technology with an active temperature regulation layer. Unlike add-on cooling solutions (mattress pads, covers), the Climate Cool builds temperature control directly into the mattress alongside Sleep Number's dual-zone firmness adjustment.

Sleep Number, a publicly traded company with over 35 years in sleep technology, positions the Climate Cool as their premium offering for sleepers who want both firmness customization and thermal management in a single system.

How It Works

The Climate Cool uses a thermoelectric cooling and heating module embedded within the mattress layers, circulating conditioned air through channels in the comfort surface. Each side of the bed has independent temperature and firmness controls. The firmness system uses adjustable air chambers (the classic Sleep Number SleepIQ technology), while the climate layer maintains a set temperature offset from ambient.

The SleepIQ app controls everything and provides nightly sleep metrics including heart rate, breathing rate, movement, and time in bed. The system tracks your SleepIQ score over time and can integrate with select smart home platforms.

Key Features

• Integrated firmness + temperature: Dual-zone adjustable air firmness (0–100 scale) combined with active cooling and heating in one mattress
• SleepIQ tracking: Built-in biometric sensors track heart rate, respiratory rate, and sleep quality without a wearable
• Air-based cooling: Thermoelectric system circulates conditioned air rather than water, eliminating leak concerns
• No add-on required: Temperature regulation is built into the mattress, not a separate pad or cover
• Proven adjustable firmness: Sleep Number's air chamber system allows precise firmness tuning for each side

Our Testing Experience

The Climate Cool's main advantage is integration. Having firmness adjustment and temperature control in one system means one app, one setup, and no separate Hub or pad on the floor. The firmness adjustment is genuinely useful—being able to dial in a Sleep Number setting for each side is something no mattress pad can replicate.

However, the temperature regulation is less aggressive than water-based systems. The air-based cooling maintains a temperature offset (roughly 5–8°F below ambient), which is noticeable but not as dramatic as the Eight Sleep Pod's ability to reach 55°F regardless of room temperature. On a hot summer night with the room at 80°F, the bed surface settled around 73°F—cooler, but not cold. The SleepIQ tracking is solid for trends but less granular than dedicated trackers. At $2,299, it sits between the ChiliPad and Eight Sleep on price, offering the unique combination of firmness control that neither competitor can match.

The Bottom Line

The Sleep Number Climate Cool is the best option for sleepers who want both adjustable firmness and active temperature regulation in a single, integrated system. Its cooling performance is moderate compared to dedicated hydronic systems, but the combination of dual-zone firmness, built-in tracking, and climate control without a separate pad justifies its position for buyers who value simplicity and all-in-one design.
