Sleep Number ComfortNext Review (2026): The First Genuinely Smart Bed in the Lineup

Who the Sleep Number ComfortNext is for

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, plus app controls, nightly sleep insights and ResponsiveAir, which is designed to make automatic pressure adjustments.

• Great fit: Buyers who want the adjustable-firmness idea plus the data and automation it was always sold with.
• Build: 12″ tall, ComfortNext collection.
• Smart features: Full Sleep Number app: ResponsiveAir automatic firmness adjustment, nightly sleep score and insights.
• Terms: 100-night In-Home Trial with mattress returns handled through Sleep Number Customer Service; original shipping/home-delivery fees are not refunded and return shipping is the customer’s responsibility. For mattresses purchased March 23, 2026 or later, Sleep Number currently lists 2 years of full warranty coverage plus 8 additional years of limited coverage, and HSA/FSA eligibility on the mattress.

Yawnder earns a commission if you buy through our links. It does not change the price you pay or what we write. Sleep Number is not stocked in our San Diego showroom — this review is based on published construction and pricing, Sleep Number’s own owner documentation and our category testing of adjustable-air beds.

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. All use adjustable air, but control systems, automatic features and return terms can vary by model and seller.

Check the controls before buying: Sleep Number says select ComfortMode mattresses support Responsive Air using the remote. Its ComfortMode guide associates the feature with the Core Control system. Ask which system is included in your exact configuration; the collection does not use Wi-Fi or the Sleep Number app. Responsive Air is designed to maintain a chosen setting, and the manufacturer says it may need to be turned on.

How it performs, category by category

ResponsiveAir

Sleep Number says ResponsiveAir responds to movement and adjusts the air chambers to maintain the selected setting. We have not independently tested how the system performs overnight.

Pressure relief

Comfort depends on your body, position, and chosen firmness. Try the mattress at home or in a store, paying attention to your shoulders and hips. Yawnder has not measured pressure relief on this model.

Cooling

Sleep Number describes built-in cooling materials. The mattress does not provide active temperature control; we have not measured its temperature performance.

Sleep tracking

The Sleep Number app provides sleep insights without a wearable. Treat the information as a wellness feature, not a medical diagnosis; we have not tested its accuracy.

Motion isolation

Partners can adjust the air chambers independently. We have not measured motion transfer, so test the mattress with a partner if movement is a concern.

Edge support

We have not measured edge support on this model. Sit and lie near the edge in your preferred setting to judge whether it feels secure.

Editorial assessment of ComfortNext

This assessment uses published specifications and category experience. Yawnder has not tested this exact model and does not assign it performance scores.

Methodology: Yawnder has not instrument-tested this exact Sleep Number model. These observations are an editorial interpretation of manufacturer documentation and our experience evaluating adjustable-air mattresses; do not compare these estimates to our measured mattress data.

Pros and cons

What we like

• ResponsiveAir is designed to maintain your selected setting.
• 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 materials are built in, but the mattress does not actively regulate temperature; we have not tested its cooling.
• 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 control; Responsive Air on select configurations), ComfortNext (app, ResponsiveAir and the Tri-Brid micro-coil builds) and Climate (active temperature control). Here is where the ComfortNext sits.

ComfortMode and ComfortMode Lux prices checked Oct. 28, 2026; other lineup information last checked Oct. 4, 2026. Official sources: Sleep Number ComfortNext guide and Sleep Number Returns & Exchanges. ComfortNext supports the Sleep Number app and Responsive Air. Prices and promotions change frequently, so use the live Sleep Number listing rather than assuming a fixed discount percentage.

Where this model fits

• Versus ComfortMode Lux: At the prices listed above, ComfortNext adds app controls, sleep insights and an extra inch. Select ComfortMode configurations can also offer Responsive Air; check the exact control system.
• 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.

Before you buy

As of October 28, 2026, Sleep Number lists the queen ComfortNext mattress at $2,999, before promotions or a base. It is 12 inches tall. The standard ComfortNext combines foam and adjustable air; the Lux and Ultra add microcoils. Compare the full cost with the foundation or adjustable base you need.

ComfortNext uses the Sleep Number app and ResponsiveAir to adjust firmness as you move. A separate remote is optional; check phone compatibility, home Wi-Fi, power access, and the current remote price before ordering. Two sleepers can set their own firmness. Try your usual positions and sit near the edge to judge comfort for yourself; Yawnder has not tested this exact model’s pressure relief, edge support, motion transfer or cooling.

For purchases directly from Sleep Number, the mattress has a 100-night in-home trial. Contact Sleep Number for authorization before a return; original delivery charges are not refunded and return shipping is the customer’s responsibility. A one-time exchanged product is final sale with no new trial; adjustable bases are also final sale. Terms may differ through another seller. See Sleep Number’s product page, ComfortNext guide, and return policy.

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 available on ComfortNext, Climate and select ComfortMode configurations; ComfortMode uses a remote to control it.

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?

Does it track sleep without a watch?

The verdict

Editorial verdict. ComfortNext is the model most people picturing a Sleep Number actually want. ResponsiveAir is designed to maintain your setting and the app provides sleep insights; whether those features justify the price depends on your preferences. It is expensive for the materials, and that is the trade you make for a bed that two people can share at different firmnesses.
