Sleep Number ComfortNext Review (2026)
Verdict: 8.0/10 — ComfortNext is the model most people picturing a Sleep Number actually want.
Short answer: ComfortNext is where the 2026 lineup starts being a smart bed rather than an adjustable one. $2,999 for a Queen buys 12 inches, enhanced relief for hips, shoulders and knees, built-in cooling materials over high-density foam, and — the actual upgrade — the app, nightly sleep insights and ResponsiveAir, which re-adjusts firmness while you sleep instead of waiting for you to press a button.

How a Sleep Number actually works
Every Sleep Number bed is an air bed at heart: an air chamber under each side of the mattress, inflated or deflated to a firmness number from 0 to 100, with foam and (on the newer models) micro-coils layered on top. Couples get two independent numbers on any size Queen and up.
What separates the 2026 models is what sits above the air: foam only on the ComfortMode beds, thicker targeted foam on ComfortNext, micro-coils in the Tri-Brid Lux and Ultra, and active temperature hardware in the Climate collection. Everything else — the pump, the numbers, the trial — is shared.

How it performs, category by category
ResponsiveAir
The feature that justifies the tier. The bed senses movement and re-inflates to hold your number as you shift, which is the fix for the classic Sleep Number complaint of waking up feeling like the bed changed overnight.
Pressure relief
A clear step up from ComfortMode. Twelve inches gives room for a real comfort system, and Sleep Number targets it at the hip-shoulder-knee line rather than adding generic softness.
Cooling
Built-in cooling materials plus a taller, more breathable build. Good for a warm sleeper, still not active cooling — that is a Climate-collection feature.
Sleep tracking
Biometric tracking with a nightly score and insights, no wearable required. Accuracy is fine for trends, not clinical. If you want an apnea-grade measurement, this is not that.
Motion isolation
Good. Independent chambers plus a thicker foam stack handle a restless partner well; the centre seam is still the weak point for couples who sleep close.
Edge support
Better than the entry beds because of the taller foam rail, but still short of a well-built coil hybrid.
How the ComfortNext scores
Scored out of 10 against beds in the same price band, not against the whole market.

Pros and cons
What we like
- ResponsiveAir keeps your number instead of drifting overnight.
- App, sleep score and insights with no wearable needed.
- Twelve inches with relief targeted at hips, shoulders and knees.
- The cheapest Sleep Number that delivers what the marketing has always promised.
What we would change
- $2,999 for a Queen buys a lot of conventional hybrid mattress elsewhere.
- Cooling is passive — hot sleepers still need ClimateCool.
- No micro-coils; the Tri-Brid build starts at ComfortNext Lux.
- App-dependent features mean an account, a Wi-Fi connection and firmware updates.
The 2026 Sleep Number lineup compared
Sleep Number cut its range from twelve mattresses to seven in March 2026 and reorganised them into three collections: ComfortMode (remote only), ComfortNext (app, ResponsiveAir and the Tri-Brid micro-coil builds) and Climate (active temperature control). Here is where the ComfortNext sits.
| Model | Collection | Height | Smart features | Queen list |
|---|---|---|---|---|
| ComfortMode | ComfortMode | 10″ | Remote only | $1,599 |
| ComfortMode Lux | ComfortMode | 11″ | Remote only | $2,099 |
| ComfortNext (this review) | ComfortNext | 12″ | App + ResponsiveAir | $2,999 |
| ComfortNext Lux | ComfortNext | 13″ | App + ResponsiveAir | $3,999 |
| ComfortNext Ultra | ComfortNext | 14″ | App + ResponsiveAir | $4,499 |
| ClimateCool | Climate | 12″ | App + ResponsiveAir | $5,499 |
| Climate360 | Climate | 13″ | App + cooling & warming | $10,249 |
Queen list prices as published by Sleep Number in August 2026. Sleep Number discounts almost continuously — the price you pay is usually 10–25% below list. Always check the live price.
Where this model fits
- Versus ComfortMode Lux: $900 more for the app, ResponsiveAir and an extra inch. Buy it only if the automation matters to you.
- Versus ComfortNext Lux: $1,000 more adds the Tri-Brid micro-coil layer and lower-back support at 13 inches — the biggest single materials jump in the lineup.
- Versus ClimateCool: $2,500 more, and the only reason to make that jump is active temperature control.

Frequently asked questions
What is ResponsiveAir?
Sleep Number’s system for sensing your movement and automatically adjusting air pressure to hold your firmness number through the night. It is standard on the ComfortNext and Climate collections and absent from ComfortMode.
How much is the ComfortNext?
$2,999 list for a Queen. Sleep Number has run the collection at 25% off, so check the current promotion before you buy.
How tall is the ComfortNext?
12 inches. ComfortNext Lux is 13 inches and ComfortNext Ultra is 14 inches.
Does ComfortNext have micro-coils?
No. The Tri-Brid design that combines micro-coils, foam and air starts with the ComfortNext Lux and Ultra.
Does it track sleep without a watch?
Yes. Sensors in the bed produce a nightly score and insights inside the Sleep Number app — no wearable required.
The verdict
8.0/10. ComfortNext is the model most people picturing a Sleep Number actually want. ResponsiveAir solves the real ownership complaint, the app gives the bed a reason to be smart, and 12 inches is enough mattress to sleep on properly. It is expensive for the materials, and that is the trade you make for a bed that two people can share at different firmnesses.
