Sleep Number 360 i10 Smart Bed Mattress Reviews (2026)

If you’re comparing smart beds and traditional mattresses, our All Mattress Reviews and Mattress Resource Hub pages are a useful place to start.

We slept on the i10 for real nights and used it during the day as part of our mattress testing process, then scored it across Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability. I focused on back and hip alignment after long desk days; Marcus Reed tracked heat buildup and edge stability; Jenna Brooks ran partner-movement checks with Ethan Cole. We also logged changes across the 0–100 Sleep Number scale to see how quickly the feel shifts and how consistent it stays once tuned.

In our at-home testing, the i10 felt most consistent once we stopped chasing a new number every night. Small adjustments helped us balance hip and lumbar support, and partner movement stayed surprisingly contained for an air-based design. The one area that never felt as solid as the center was the perimeter—fine for most sleep positions, but less reassuring for sitting or edge sleeping.

Our Testing Experience

What we liked

• Per-side adjustability made it easier to support the lower back without making the whole surface feel too firm.

• Partner motion stayed fairly contained in our couple tests, so turning didn’t trigger full-bed ripples.

• The top felt less heat-trapping than many foam-heavy beds once we settled into our preferred settings.

Who it is best for

• Couples who need different firmness on each side.

• Back/side combo sleepers who respond well to small firmness tweaks.

• Sleepers who want app-based tracking and smart comfort features.

Where it falls short

• The edge felt less confidence-inspiring than the center for sitting and edge sleeping.

• You’ll likely need a dialing-in period before it feels “right.”

• Total cost can climb quickly, especially if you add a base.

• Mattress model: Sleep Number 360 i10 Smart Bed Mattress

• Price (Queen, list price shown): $5,499 (promotions vary)

• Mattress height: 13"

• Firmness adjustability: Sleep Number setting 0–100; DualAir adjustability (each side independently)

• Support core: adjustable air-chamber technology

• Comfort materials (not exhaustive): memory foam and other comfort foam layers; temperature-balancing cover/materials noted

• Smart features: SleepIQ sensors for sleep tracking in the smart bed system

• Auto-adjust feature: Responsive Air (smart feature in Sleep Number smart beds)

• Trial: 100-night in-home trial; returns/exchanges can be initiated starting day 31 with a $250 fee ($350 in extended service areas)

• Warranty: 15-year limited warranty

• Delivery options: delivery and in-home setup options are available

Overall Score (average): 4.2/5

Choose the i10 (after you’ve covered the basics of how to choose a mattress) if per-side firmness control is your top priority and you’re willing to spend a couple of weeks dialing in a small range of settings that feels right. In our testing, side sleepers generally did better slightly softer for shoulder and hip comfort, while back sleepers often preferred firmer support to keep the pelvis from sinking. If you dislike tech friction or want a sturdier edge, a simpler mattress may be easier to live with.

If you want a different take on the same core goals, here are two common alternatives:

• Want adjustable firmness with a more traditional luxury vibe: Saatva Solaire

• Want strong cooling without air-chamber tuning: Brooklyn Bedding Aurora Luxe

The biggest trade-off with the i10 is that it’s rarely “perfect” on day one. Most sleepers will need a short period of small adjustments to find the right setting band. Edge stability is the other clear compromise: the perimeter feels less supportive than the center, especially when you sit down to get dressed or sleep right on the edge.

• Why people pick each model

  • i10: Best for per-side firmness tuning, strong motion isolation, and smart features that help keep comfort consistent

• Alternatives to consider

  • Saatva Solaire: adjustable air support with a plush, luxury finish

  • Tempur-Pedic TEMPUR-ActiveBreeze: a premium, cooling-forward smart bed experience

  • Brooklyn Bedding Aurora Luxe: a cooling-focused hybrid with a sturdier edge feel

• Make small changes (5–10 points) and keep them for a few nights before changing again.

• Hips sinking? Go a bit firmer. Shoulders feeling pinched? Go a bit softer.

• Check pillow height and neck alignment before blaming the mattress.

• For couples, set each side independently and recheck after about two weeks.

• Use edge sitting as a quick check—if it feels wobbly, avoid sleeping right on the perimeter.

• If you sleep warm, pair breathable sheets with the bed’s temperature-balancing cover.

• After heavy training or sore weeks, a slightly softer setting can ease new pressure points.

• Avoid nightly tweaking—give your body time to adjust.

• If you add an adjustable base, try a zero-gravity position on desk-heavy days.

In the center, it feels more structured than a basic air bed because the comfort foams add a more traditional mattress feel. Near the edges, it can feel less planted, especially when sitting.

It’s straightforward, but it isn’t instant. The simplest approach is to make small changes and keep them for a few nights so you can judge how your back and hips feel in the morning.

Yes—mainly because motion stays contained and each side can be tuned separately. The main couple caveat is edge space: if both sleepers sprawl outward, the perimeter may feel less secure.

Sleep Number requires at least 30 nights before initiating a return or one-time exchange, and there’s a return/exchange fee. Plan on committing to a real dialing-in period before you decide.
