The Sleep Number Climate360 Smart Bed Mattress is a premium smart bed for couples and sleepers who run hot or cold and want active temperature control with adjustable firmness. In our tests, the climate system made a real difference across the night, but the bed asks more of you than a standard hybrid and the edge felt softer than we wanted for frequent sitting.

Product Overview
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Sleep Number Climate360 Smart Bed Mattress | 4.2/5 | Active cooling and warming, adjustable firmness, and strong couple-side customization | Learning curve, softer edge feel, and more system noise than a standard mattress | Couples with different temperature preferences and sleepers who want a more adjustable setup |
Final Verdict
You buy the Climate360 for control. It gives you temperature on each side, firmness that can be changed as needed, and an included adjustable base that makes the bed more useful for reading, winding down, and recovery. Our testing showed that the climate features worked better than the passive cooling materials we usually see, but the bed is not especially simple, and the perimeter still feels softer than the best traditional hybrids.
Who It's For
- Couples who want different temperatures on each side
- Hot sleepers who wake up overheated
- People who read, recover, or spend time in bed and want adjustable positions
Who It's Not For
- Anyone who wants a fully plug-and-play mattress
- People who rely on a very firm perimeter for daily sitting
- Shoppers who prefer one fixed feel with almost no setup
How We Tested It
We used the Climate360 through multiple nights instead of locking in one preset and calling it done. Our full mattress testing process covered Support and Pressure Relief in both side and back sleeping, then repeated those checks after longer reading and lounging sessions. We also tracked firmness changes as we adjusted the bed, checked Cooling by looking at how quickly heat cleared and how stable the surface felt overnight, and ran Motion Isolation, Responsiveness, and Edge Support tests with partner movement, repeated position changes, and seated edge use.
Our Testing Experience
The first few nights felt more like learning a system than breaking in a mattress. We spent time dialing in the Sleep Number setting, testing a bedtime temperature routine, and switching from warming into cooling once we were settled. After that adjustment period, the bed felt much more intuitive. The climate effect was not just cool-to-the-touch at the start of the night; it stayed noticeable when we woke up warm and wanted the surface to recover faster.
Marcus pushed the cooling harder than anyone on the team and liked how well it cut down on that sticky, heat-held feel. Jenna and Ethan paid the closest attention to couple sleep. Once both sides were dialed in, movement stayed fairly controlled, but the middle felt less natural when the firmness settings were too far apart.
What We Liked
- The climate effect stayed noticeable through the night instead of fading after first contact.
- Adjustable firmness made it easy to fine-tune support from night to night.
- The base presets made reading and wind-down time genuinely more comfortable.
Who It Is Best For
- Couples with different temperature preferences
- Sleepers who wake up too hot or too cold
- People who want one bed to handle sleep, reading, and recovery
Where It Falls Short
- The edge compresses more than we would like for daily sitting.
- Setup and routines take more patience than a standard mattress.
- Large firmness gaps between partners can make the middle feel awkward.

Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.4/5 | Once tuned, it kept our hips and lower back aligned well. |
| Cooling | 4.6/5 | The active system cleared heat faster than most passive designs we test. |
| Pressure Relief | 4.1/5 | Good once dialed in, but not as instant as a deep memory-foam feel. |
| Motion Isolation | 4.2/5 | Partner movement stayed fairly contained when both sides were set close together. |
| Responsiveness | 4.0/5 | Easy enough to move on, though not especially springy. |
| Edge Support | 3.9/5 | Secure for sleep, but softer than ideal for seated edge tasks. |
| Durability | 4.0/5 | Coverage is solid, but the added tech raises more long-term service questions than a simple mattress. |
| Overall | 4.2/5 | Excellent climate control and customization, with a clear complexity trade-off. |
Choosing Climate360
Choose the Climate360 if the climate features are the point, not just a bonus. The bed makes the most sense for shoppers who want active temperature control, adjustable comfort, and a base that adds real day-to-night versatility.
If you are a lighter side sleeper who wants more automatic pressure relief, the Tempur-Pedic TEMPUR-ProAdapt is the cleaner comparison. If adjustable-air comfort matters more than active climate tech, the Saatva Solaire is the simpler alternative. If you mainly want temperature tech without replacing your mattress, an Eight Sleep cover makes more sense.
Limitations
This bed rewards hands-on owners. If you are unlikely to use routines, presets, or regular adjustments, part of the value disappears. It is also only average for daily edge sitting, and big differences between both sides can create a split feel through the middle. If you want a mattress that feels settled from night one with almost no setup, this will probably feel too involved.
Climate360 vs Alternatives
Why Choose It
- You want dual-zone active cooling and warming.
- You need adjustable firmness that can change with your comfort needs.
- You want an included adjustable base instead of building that setup separately.
Alternatives to Consider
- Saatva Solaire Mattress: adjustable-air comfort with less climate tech to manage.
- Tempur-Pedic TEMPUR-ProAdapt Mattress: deeper contouring with a more traditional mattress feel.
- Eight Sleep Pod Cover: tech-driven temperature control if you want to keep your current mattress.
Pro Tips
- Start cooling or warming about 30 minutes before bed so the surface is ready when you are.
- Use Foot Warming briefly at bedtime, then switch to cooling or a sleep routine once you settle in.
- Keep both sides fairly close in feel if you share the bed and want a smoother center section.
- Save one base preset for reading and one for sleep so you do not keep hunting for the same position.
- Keep your bedding breathable so the climate system can do its job.
- Give yourself about a week before deciding whether your final setting is right.
- Expect some system presence when the climate layer is working; it is noticeable, but not loud.
- If your body feels different after travel or a tough training week, revisit your settings instead of assuming the mattress changed.
FAQs
Does it feel cooler all night or just at first?
In our tests, it felt like active heat management rather than a brief cool-touch effect. The difference showed up most when we woke up warm and the bed cleared that heat faster than most passive cooling beds do.
Is it good for couples who move a lot at night?
It can be, as long as both sides are set reasonably close to each other. We found that movement stayed fairly localized, but the middle felt less natural when the two sides were tuned too far apart.
Is the edge firm enough for daily sitting?
It is usable, but not one of this bed's strongest areas. If you sit on the side every morning to get dressed, you will probably want a mattress with a firmer perimeter.
Is it hard to find the right settings?
The first few nights take patience. Once we treated it like a routine instead of a one-time setup, it became much easier to live with.
Does the adjustable base change the feel?
Yes. Elevation changes how pressure is distributed, so we needed slightly different settings for reading, winding down, and flat sleeping.
