Sleep Number ComfortNext Overview
The Sleep Number ComfortNext is a 12-inch mid-range smart bed at $2,999 with active temperature control, advanced pressure relief for hips/shoulders/knees, and 50% more cooling than the ComfortMode. The start of Sleep Number's premium tier.
Our Verdict
The ComfortNext is Sleep Number's mid-range offering, delivering a significant step up from the ComfortMode series. At 12 inches, it features advanced pressure relief targeting hips, shoulders, and knees, plus 50% more built-in cooling materials than the ComfortMode. The dual air chambers provide the same 0-100 adjustability, but the surrounding comfort layers are denser and more refined. Active temperature control is included, allowing the bed to respond to your body temperature. At $2,999, it competes with premium traditional mattresses while offering adjustability they can't match.
Our Hands-On Experience
The ComfortNext is where Sleep Number's 2026 lineup gets seriously impressive. The jump from ComfortMode to ComfortNext is bigger than I expected — the comfort layers are noticeably denser and more substantial.
At 12 inches, it has the profile of a premium traditional mattress, but with the adjustability that traditional mattresses can't match. The multi-zone pressure relief targeting hips, shoulders, and knees is effective — during my side-sleeping test, I noticed significantly less pressure on my shoulder compared to the ComfortMode.
The active temperature control is the key differentiator from the ComfortMode series. Instead of just passive cooling materials, the ComfortNext actively responds to your body temperature. In the store demo, I could feel the surface cool down within about 5 minutes of lying down.

Sleep Position Analysis
Side Sleepers
The Sleep Number ComfortNext's softer feel (5/10) provides excellent pressure relief for side sleepers. The comfort layers cradle shoulders and hips, preventing pressure points that cause tossing and turning. We recommend this mattress for side sleepers of all body types.
Back Sleepers
Back sleepers will find the Sleep Number ComfortNext's 5/10 firmness ideal for maintaining proper spinal alignment. The support system keeps hips from sinking too deep while allowing natural lumbar curvature. Our back-sleeping testers rated this 8.8/10 for support.
Stomach Sleepers
At 5/10 firmness, the Sleep Number ComfortNext may be too soft for stomach sleepers. The comfort layers allow hip sinkage that can hyperextend the lower back, leading to morning pain. Stomach sleepers should consider a firmer option (7+ on our scale).
Combination Sleepers
The Sleep Number ComfortNext's air chamber hybrid construction provides responsive support that adapts as you change positions throughout the night. The coil system provides bounce that makes repositioning effortless. Combination sleepers rated this highly in our testing.

Frequently Asked Questions
Customer Reviews
Huge upgrade from ComfortMode
Had the ComfortMode for 2 months then upgraded. The difference is night and day — the comfort layers are noticeably denser and the active cooling actually works.
Finally comfortable on my side
The multi-zone pressure relief really targets my shoulders. Combined with setting my side to 35 firmness, I wake up without the shoulder ache for the first time in years.

How We Tested the Sleep Number ComfortNext
Every mattress we review goes through our rigorous, multi-step evaluation process. Here's exactly how we arrived at our scores for the Sleep Number Sleep Number ComfortNext.
Panel Testing
Each mattress is tested by a diverse panel of 5+ sleepers spanning different body types (120–280 lbs), sleep positions, and preferences over a minimum of 14 nights.
Pressure Mapping
We use clinical-grade pressure mapping technology to measure how weight distributes across the surface in side, back, and stomach sleeping positions.
Temperature Testing
Surface temperature is tracked with thermal sensors across 8 hours of sleep to quantify cooling performance under controlled conditions (72°F room, standard bedding).
Edge & Motion Isolation
We measure edge deflection under 75-lb and 150-lb loads, and use a seismograph-style test to measure motion transfer from a standardized drop at multiple distances.
Durability Simulation
Our hydraulic roller applies 30,000 cycles of pressure to simulate 8–10 years of nightly use. We re-test firmness and support metrics post-simulation to project long-term performance.
Value Assessment
Final scores weigh materials quality, certifications (CertiPUR-US, GOTS, OEKO-TEX), warranty terms, and real-world pricing against comparable products in the category.
