Quick verdict
Verdict: Editorial take — ComfortMode does one thing well and is honest about the rest.
Short answer: ComfortMode is the cheapest way into a Sleep Number in 2026 — $1,999 for a Queen, 10 inches tall, hybrid foam-over-air with built-in (passive) cooling materials. The catch that most reviews skip: the whole ComfortMode collection is deliberately offline. No Wi-Fi, no app, no SleepIQ score. A remote adjusts firmness; some configurations also support automatic Responsive Air. Confirm the control system before ordering.

- Great fit: Couples who want two firmness settings in one bed on the smallest possible budget.
- Build: 10″ tall, ComfortMode collection.
- Smart features: Remote-controlled firmness; no Wi-Fi, app or sleep tracking. Select configurations support Responsive Air through the remote.
- Terms: 100-night In-Home Trial; 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
Firmness range
Adjustable air chambers let partners select different firmness settings in a queen. The feel of any number is subjective, so try several settings in your usual positions rather than assuming a number corresponds to a particular firmness.
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.
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.
Noise and mechanics
The mattress uses an electric pump and air hoses. Ask for a demonstration of the pump and check that hoses and the power connection remain accessible.
Editorial assessment of ComfortMode
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
- Cheapest genuine dual-firmness bed Sleep Number sells — Queen at $1,999.
- Simple: a remote, two numbers, no app account to maintain.
- Same 100-night In-Home Trial framework as the current lineup; for mattresses purchased March 23, 2026 or later, Sleep Number lists 2 years of full warranty coverage plus 8 additional years of limited coverage.
- HSA/FSA eligibility may reduce after-tax cost for eligible buyers, but the actual savings depend on your plan and tax situation.
What we would change
- No app, no Wi-Fi, no sleep tracking — if you wanted the data, this tier is the wrong one.
- Only 10 inches, so pressure relief at low firmness numbers is thin.
- Passive cooling only.
- Air-bed edge support and a noticeable centre seam.
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 ComfortMode sits.
| Model | Collection | Height | Smart features | Queen list |
|---|---|---|---|---|
| ComfortMode (this review) | ComfortMode | 10″ | Remote; select configurations support Responsive Air | $1,999 |
| ComfortMode Lux | ComfortMode | 11″ | Remote; select configurations support Responsive Air | $2,499 |
| ComfortNext | 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 |
ComfortMode and ComfortMode Lux prices checked Oct. 28, 2026; other lineup information last checked Oct. 4, 2026. Official sources: Sleep Number ComfortMode guide and Returns & Exchanges.

Where this model fits
- Versus ComfortMode Lux: $500 more buys an extra inch, 25% more cooling material and real hip support. If you sleep on your side, pay it.
- Versus ComfortNext: At the prices listed above, ComfortNext adds app controls, sleep insights and two inches. Select ComfortMode configurations may also offer automatic Responsive Air; check the control system before comparing.
- Versus a $1,999 coil hybrid: a conventional hybrid offers a different feel and construction. Try both, including their edges, before choosing; we have not compared these models in testing.

Before you buy
As of October 28, 2026, Sleep Number lists a queen ComfortMode mattress at $1,999 and the ComfortMode Lux at $2,499, before any promotion or base. The standard model is 10 inches tall; Lux is 11 inches. Check the current price and the cost of a compatible foundation or adjustable base before ordering.
ComfortMode uses a remote rather than the Sleep Number app. For a queen, partners can choose different firmness settings; try several settings in your normal sleep positions and check the feel where the chambers meet. Ask which remote and control system are included, and confirm electrical access and base compatibility.
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 and return policy.
Frequently asked questions
Does the Sleep Number ComfortMode have an app?
No. Sleep Number states that the ComfortMode collection does not support Wi-Fi connectivity or app use. Firmness is set with the remote. Sleep tracking starts at the ComfortNext collection.
How much is a Queen ComfortMode?
Our page tracks Sleep Number’s published list price, but promotions change frequently. Check the live Sleep Number listing for the current Queen price rather than assuming a fixed percentage discount.
Is ComfortMode good for side sleepers?
Side-sleeper comfort depends on body shape and firmness setting. Try it in your usual position, paying attention to shoulder and hip pressure; Yawnder has not tested pressure relief on this model.
Does it sleep cool?
Sleep Number lists built-in cooling materials, but this model does not actively regulate temperature. We have not tested its cooling performance.
What is the warranty?
ComfortMode ships with a 100-night In-Home Trial; 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.
The verdict
Editorial verdict. ComfortMode does one thing well and is honest about the rest. If two people in the bed disagree about firmness and the budget is $1,600, it earns its place. If you came for sleep tracking, cooling or plush pressure relief, every one of those lives further up the lineup.
