The Sleep Number ClimateCool smart bed is a premium, app-connected model built for hot sleepers who want active cooling and adjustable firmness on both sides. It sits in the luxury tier and makes the most sense for couples with different comfort needs. It is less appealing if you want a simple mattress that does not rely much on app-based features.

Product Overview
| Mattress | Overall Score | Pros | Cons | Ideal For |
| Sleep Number ClimateCool smart bed | 4.3/5 | Active cooling, adjustable firmness, strong personalization | High price, app reliance, edge feel changes at softer settings | Hot sleepers, couples, back sleepers, and side sleepers who like to tune the feel |
Final Verdict
If you want cooling you can feel and the ability to tune firmness by side, this bed offers a highly personalized sleep setup. In our testing, the cooling stayed noticeable well past bedtime, especially on warmer nights. The main tradeoffs are the price and the fact that scheduled temperature control works through the app.
Who It’s For
- Hot sleepers chasing a cooler surface feel
- Couples who want different firmness and cooling on each side
- People who like adjusting settings over time for comfort
Who It’s Not For
- Shoppers on a strict budget
- Anyone who dislikes app-driven features
- Those who want a classic, no-tech mattress experience

How We Tested It
Our testing started with a baseline Sleep Number setting for alignment, then ran cooling both manually and on a nightly program to compare the surface feel at bedtime with the middle of the night. We graded support, cooling, pressure relief, motion isolation, responsiveness, edge support, and firmness changes with short mobility drills, partner-movement checks, and repeated nights of sleep. We also tracked how the bed felt as we moved from softer to firmer settings.
Our Testing Experience
Sleep Number ClimateCool smart bed
Our Testing Experience
In our testing, the biggest change was how quickly heat stopped building under the shoulders and hips. We adjusted the setting upward until lower-back support felt steadier, then softened it slightly to see where side-sleeping pressure eased without losing alignment. Marcus, who sleeps hotter and has a heavier build, paid close attention to hip support; Jenna and Ethan focused on motion transfer, getting in and out of bed, and how stable the edge felt when the settings were farther apart.
What we liked
- Cooling feels active, not just cool to the touch
- Adjustable firmness makes support easier to dial in
- Comfort is easy to fine-tune when your body feels different from week to week
Who it is best for
- People dealing with night sweats or stubborn heat buildup
- Couples with different firmness preferences
- Back and side sleepers who want tunable support
Where it falls short
- Luxury pricing is the biggest barrier
- Scheduled cooling relies on the app
- Softer settings feel less secure at the edge

| Adjustable firmness on each side | Scheduled cooling depends on the app |

How to Choose the ClimateCool
Choose this bed if passive cooling covers have not been enough, you want to fine-tune support for back or side sleeping, or you share a bed with someone who wants a very different feel. Skip it if you want a simpler mattress, rarely adjust settings, or are trying to keep costs down.

Limitations
This bed makes the most sense when you use its features. If you are not going to adjust firmness or cooling, a lot of the value goes unused. People who want a classic, low-tech mattress may find the app workflow and added system complexity frustrating. If you need a consistently firm perimeter for frequent sitting or mobility support, softer settings may not feel secure enough.
ClimateCool vs. Alternatives
Why choose this bed
- Active cooling you can control on each side
- Adjustable firmness that makes support easier to refine over time
- Smart programs that automate nighttime cooling
Alternatives to consider
- A simpler cooling mattress if you want less setup and fewer app features
- An adjustable model if firmness tuning matters more than active cooling
- A contouring foam bed if pressure relief matters more than temperature control
Pro Tips for ClimateCool
- Start a little firmer than you expect, then soften in small steps until pressure points ease.
- Give each new setting a few nights before changing it again.
- Use a preset cooling schedule for several nights before building a custom one.
- If cooling feels too cold, shorten the timer before lowering it for the whole night.
- Keep both sides closer together if motion sensitivity is a priority.
- Avoid very soft settings if edge stability matters.
- Turn on Responsive Air if your support needs shift from night to night.
- Use breathable bedding so the cooling effect is not muted.
- Recheck your settings after body or routine changes.
FAQs
Does the cooling feel real, or just cool to the touch?
It felt active and sustained. In our testing, it managed heat buildup instead of only feeling cool when you first got into bed.
Can two partners use different cooling levels?
Yes. Cooling is controlled independently on each side, so one sleeper can run it colder while the other stays closer to neutral.
Is scheduled cooling optional?
Yes. You can turn cooling on manually or use a nightly SmartTemp program so the bed runs automatically.
Does changing firmness affect the feel of motion transfer?
Yes. In our use, motion was easier to notice when the two sides were set much farther apart.
