Temperature is one of the biggest silent sleep disruptors. If your body gets too warm or too cold, you’re more likely to wake up and spend longer in lighter sleep stages.
Climate360® is Sleep Number’s top-tier answer to that problem, pairing real temperature control with adjustable support and built-in biometric tracking.
Unlike most “cooling mattresses” that rely on passive foams or gels, Climate360 actively cools or warms the bed surface and lets each sleeper set their own climate.
Sleep Number positions it as a full system, not just a mattress, and current pricing reflects that premium category.
Active dual-zone climate control
Climate360 can heat or cool each side of the bed independently, with a wide temperature range that covers both hot and cold sleepers.
This matters for couples with opposite comfort needs, but it also helps solo sleepers whose temperature shifts during the night.
You can set a steady temperature or schedule changes. For example, some users prefer stronger cooling during the first half of the night, followed by a mild warm-up before waking.
It may take a few nights to fine-tune your ideal schedule, but once dialed in, the bed maintains that micro-climate consistently.
Adjustable firmness + responsive support
Beneath the comfort layers, Sleep Number’s air chambers let you set firmness on a 0–100 scale. That gives more precise control than standard soft/medium/firm categories.
The system also includes Responsive Air® technology that detects movement and subtly adjusts support when you change positions.
In practice, this can help:
- Side sleepers who need more shoulder and hip pressure relief.
- Back sleepers who want consistent lumbar support.
- Combination sleepers who shift often and don’t want to wake to readjust.
Built-in SleepIQ® tracking
Climate360 includes SleepIQ® sensors that track sleep without a wearable. It measures motion patterns and biometrics such as breathing and heart rate trends, then produces a nightly SleepIQ score plus longer-term insights in the app.
The value isn’t just the score. It’s the ability to connect changes in climate or firmness to actual sleep outcomes over time. Data-focused sleepers can test what settings keep them asleep longer and adjust based on results.
Integrated adjustable base
The bed ships with a full adjustable base as part of the system. You can raise head and foot areas independently, save presets, and use a Zero Gravity position intended to reduce pressure on the lower back and aid circulation.
Because the climate and firmness features are split by side, the base movement is also designed to limit motion transfer between sleepers. That helps if one person likes to sit up to read while the other stays flat.
Price, trial, and warranty
Climate360 sits at the top of Sleep Number’s lineup. Typical pricing falls in the high premium range depending on size and configuration, and sales can lower the total.
The bed includes a 100-night trial and a long limited warranty consistent with other 360-series models.
Who Climate360 fits best
This system is most convincing when temperature or shared-bed compromise is the real problem.
- Hot or cold sleepers: If you regularly wake overheated or chilled, active control is more dependable than passive “cooling” foams.
- Couples with different needs: Dual-zone temperature and firmness remove the need to meet in the middle.
- People managing discomfort: Adjustable firmness plus responsive support can reduce pressure-related wakeups.
- Sleep-data enthusiasts: SleepIQ makes it easy to verify what’s working.
Limitations to weigh
The biggest drawback is cost. This is a luxury system, and the price reflects its integrated tech. It’s also tech-dependent. App controls are central, so power outages or Wi-Fi issues can limit features until restored.
Finally, because the base is integrated, you’re buying a full setup, not a mattress you can separate later. That’s great for performance, but it matters if you move often or have a tight bedroom layout.
Bottom line
Climate360® is one of the few beds that treats temperature, support, and sleep tracking as one coordinated system.
If thermal discomfort is breaking your sleep or you and a partner can’t agree on comfort settings, it offers a clear, science-aligned solution.
If your sleep issues are mild or budget is a priority, a simpler adjustable-firmness bed or passive-cooling mattress may be the more practical step.
