Sleep Number Mattress Reviews (2026)

Sleep Number is worth considering when two people want different firmness levels but do not want separate mattresses. Its 2026 reset makes the choice simpler: seven current beds now span basic remote-controlled adjustability, app-connected comfort, and active temperature control. Our firsthand findings come from the retired c2, c4, p6, and i10 generation, so this update keeps those observations separate from the new lineup. The main appeal of a smart bed remains easy to understand, especially for couples: each side can feel different. The tradeoff is a higher price, more powered parts, and less edge stability when the air setting is very low. Shoppers who mainly want firmness control should start with the simpler adjustable mattresses in the range before paying for sleep data or temperature features.

The Current Lineup at a Glance

Mattress Published Queen starting price Key design feature Main drawback Best fit
ComfortMode $1,599 10-inch foam-and-air design; remote control; no app Thinnest comfort build Budget-minded shoppers who want straightforward firmness control
ComfortMode Lux $2,099 11-inch remote-controlled design with more comfort material $500 more without smart features People who want more pressure-relieving cushioning without an app
ComfortNext $2,999 12-inch foam-and-air smart bed with five-zone comfort material Large jump from ComfortMode Lux Shoppers who want an app-connected smart mattress without microcoils
ComfortNext Lux $3,999 13-inch Tri-Brid design with 1.5-inch microcoils, foam, and air Premium price before an adjustable-base upgrade Couples who want a more responsive comfort system
ComfortNext Ultra $4,499 14-inch Tri-Brid design with a 2.4-inch microcoil section Smaller practical gain over Lux than the price suggests Buyers comparing luxury mattresses with deep cushioning
ClimateCool $5,499 12-inch smart bed; active cooling; integrated base included Expensive if active cooling is not essential Persistent hot sleepers who want an active-cooling mattress
Climate360 $9,999 13-inch heating-and-cooling bed with smart adjustable base Highest price and most complex system Couples with different temperature preferences and a luxury budget

These figures are published starting prices, not guaranteed checkout totals. Promotions, delivery, size, and base choices can change the final price. ClimateCool starts with an integrated base, while Climate360 includes a smart adjustable base, so neither package is directly comparable with a mattress-only price.

Which Sleep Number Mattress Makes the Most Sense?

ComfortMode is the strongest value in the lineup. It gives each side independent firmness control for $1,599 and includes a remote, making it the clear choice when adjustability matters more than sleep tracking.

ComfortMode Lux is the better non-connected option for sleepers who want a little more cushioning. The extra inch is useful, but the $500 step makes sense only if the base ComfortMode feels too lean near the shoulders and hips.

ComfortNext is the most sensible entry point to Sleep Number's connected range. Its app, sleep insights, and five-zone comfort material add more than novelty, although shoppers who do not plan to review sleep data can save substantially with ComfortMode Lux.

ComfortNext Lux is the most meaningful construction upgrade. Its 1.5-inch microcoil section gives it a different support structure from ComfortNext, which makes the $1,000 increase easier to understand than a simple increase in foam thickness.

ComfortNext Ultra is for buyers who already know they want the deepest ComfortNext build. The larger 2.4-inch microcoil section and 14-inch profile are real changes, but Lux should satisfy most people considering this part of the range.

ClimateCool is the focused choice for persistent overheating. Its active system tackles heat more directly than cooling foam or fabric, and the starting package includes an integrated base. Occasional hot sleepers can get better value elsewhere.

Climate360 makes sense only when separate heating and cooling plus full base articulation will be used regularly. It is the most capable package, but its $9,999 starting price is difficult to justify if adjustable firmness is the main goal.

How the Seven Mattresses Differ

Model Height Control Sleep insights Temperature system
ComfortMode 10 inches Remote No Temperature-balancing materials
ComfortMode Lux 11 inches Remote No More cooling material
ComfortNext 12 inches App; optional smart remote Yes Passive cooling material
ComfortNext Lux 13 inches App; optional smart remote Yes Passive cooling and added airflow
ComfortNext Ultra 14 inches App; optional smart remote Yes Most passive cooling material in the collection
ClimateCool 12 inches App; optional smart remote Yes Active cooling, advertised up to 15°F cooler
Climate360 13 inches App; optional smart remote Yes Active heating or cooling, advertised up to 15°F either way

Sleep Number settings run from 0 to 100, with 100 the firmest. Queen and larger configurations can save a different setting for each side. ComfortMode keeps control on a physical remote, while ComfortNext and Climate models add connected controls and sleep information.

What We Tested—and What We Have Not

Our original mattress testing covered the c2, c4, p6, and i10 generation, which is no longer the current shopping lineup. We rated support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability on a 5-point scale. Overnight notes were paired with repeated checks such as sitting near the edge, changing positions slowly, tracking partner movement, and trying several air settings.

Those legacy beds showed the category's central strengths and weaknesses. Firmness changes were easiest to feel beneath the hips and lower back, partner movement stayed well contained, and the perimeter felt less steady at softer settings. The seven current mattresses were not part of that test, so we have not carried old scores forward or turned specifications into performance grades. A current model will receive a 5-point score only after completing the same process, including our firmness checks.

A Closer Look at the Current Sleep Number Lineup

The profiles below explain what changes from one model to the next. They are based on current designs and policies rather than a new hands-on test, so recommendations focus on features, price, and likely use—not unearned performance scores.

ComfortMode

What the specifications show

ComfortMode is a 10-inch foam-and-air mattress controlled by an included remote. It skips Wi-Fi and app features, leaving adjustable firmness, basic cushioning, and temperature-balancing material as the main reasons to buy it.

What we liked

  • It delivers Sleep Number's core two-sided firmness adjustment at the lowest price in the range.

  • The remote keeps everyday changes simple and avoids making a phone part of the bedtime routine.

Who it is best for

  • Shoppers comparing mattresses under $2,000 who want different firmness levels on each side.

  • People who value a simpler system more than sleep tracking or automatic adjustments.

Where it falls short

  • It has the shallowest comfort system in the current lineup.

  • There is no app, sleep reporting, or active temperature control.

ComfortMode Lux

What the specifications show

ComfortMode Lux adds an inch of height and more comfort and cooling material while staying remote-controlled. It is the logical non-connected upgrade for someone who likes ComfortMode's simplicity but wants a more substantial surface.

What we liked

  • The deeper build should provide more room for pressure-relieving cushioning before the air chamber becomes noticeable.

  • It keeps separate firmness control without adding Wi-Fi, sleep data, or another account.

Who it is best for

  • Side and combination sleepers choosing between the two ComfortMode beds.

  • Couples who want a less lean comfort layer but still prefer physical controls.

Where it falls short

  • The $500 increase buys a modest physical upgrade rather than a new control system.

  • ComfortNext is the next step if sleep insights matter.

ComfortNext

What the specifications show

ComfortNext is the first app-connected model in the new range. Its 12-inch foam-and-air build uses five-zone comfort material and adds Responsive Air, personalized sleep insights, and optional smart-remote control. It does not contain the microcoils used in Lux and Ultra.

What we liked

  • It combines the deeper comfort system with the connected features that define Sleep Number's smart range.

  • The five-zone layer is a practical step up from simply adding uniform foam.

Who it is best for

  • People who will use sleep information to fine-tune firmness and bedtime habits.

  • Mixed-position sleepers who want more cushioning than the ComfortMode pair provides.

Where it falls short

  • The starting price rises by $900 over ComfortMode Lux.

  • Its temperature features are passive, and its construction lacks the microcoil response of Lux and Ultra.

ComfortNext Lux

What the specifications show

ComfortNext Lux is the first Tri-Brid model, combining air chambers and foam with a 1.5-inch section of individually wrapped microcoils. That coil section sits around the midsection to add support and durability beneath the hips and lower back.

What we liked

  • The microcoils create a clear construction difference from ComfortNext rather than adding thickness alone.

  • Its 13-inch profile balances a deeper comfort system with less bulk than Ultra.

Who it is best for

  • Back and combination sleepers who want more response through the center of the bed.

  • Couples who want app-connected adjustability but prefer a less foam-dominant build.

Where it falls short

  • The $3,999 starting price does not include every adjustable-base option.

  • Sleepers buying mainly for cooling still need to consider ClimateCool.

ComfortNext Ultra

What the specifications show

ComfortNext Ultra expands the Tri-Brid idea to a 14-inch profile with a 2.4-inch microcoil section and the deepest comfort build in the collection. It keeps the same connected firmness controls and sleep insights as ComfortNext Lux.

What we liked

  • It is the fullest ComfortNext design without moving to a temperature-control package.

  • The taller microcoil section gives the upgrade a clearer purpose than extra foam alone.

Who it is best for

  • Shoppers seeking a luxury mattress with deep cushioning and adjustable firmness.

  • Couples who want Sleep Number's most substantial non-Climate model.

Where it falls short

  • Its $4,499 starting price is only $1,000 below ClimateCool's package price.

  • Anyone already satisfied with Lux may gain little from the extra inch and larger coil section.

ClimateCool

What the specifications show

ClimateCool actively draws warm air away from each sleeper and is advertised to make either side feel up to 15°F cooler. The 12-inch smart bed includes an integrated base at its published starting price, along with firmness adjustment and connected sleep features.

What we liked

  • Active cooling addresses persistent heat more directly than cooling fibers or foam.

  • Each side can have its own firmness and cooling program, which is useful when only one partner sleeps hot.

Who it is best for

  • Persistent hot sleepers comparing the best cooling mattresses.

  • Couples who want active cooling but do not need Climate360's heating or full smart-base package.

Where it falls short

  • The $5,499 starting price is hard to justify when overheating is occasional.

  • The cooling system adds powered parts, setup, and operating noise that passive beds do not have.

Climate360

What the specifications show

Climate360 is a complete smart-bed package rather than a mattress-only upgrade. It can actively cool or warm each side by up to 15°F and includes a smart adjustable base with separate head and foot positioning.

What we liked

  • Independent heating and cooling directly addresses partners with opposite temperature preferences.

  • The included base brings firmness, temperature, and sleep position into one control system.

Who it is best for

  • Couples who will regularly use separate temperature programs and base positions.

  • Luxury shoppers who want the broadest Sleep Number feature set in one purchase.

Where it falls short

  • The $9,999 starting price is almost double ClimateCool's package price.

  • It is excessive if separate firmness is the only feature that matters.

What Changes as Prices Rise?

Mattress Status Construction Comfort emphasis Temperature approach Hands-on score
ComfortMode Current Foam and air Basic contouring Balancing material Not tested
ComfortMode Lux Current Foam and air Deeper comfort layer More cooling material Not tested
ComfortNext Current Foam and air Five-zone support material Passive cooling Not tested
ComfortNext Lux Current Microcoils, foam, and air Hips and lower back Passive cooling and airflow Not tested
ComfortNext Ultra Current Microcoils, foam, and air Deepest ComfortNext build Most passive cooling in range Not tested
ClimateCool Current Smart bed with integrated base Whole-body contouring Active cooling Not tested
Climate360 Current Smart bed and adjustable base Whole-body contouring Active heating and cooling Not tested

“Not tested” is deliberate. A 5-point score should come from direct, repeatable evaluation, not a conversion of product specifications or marketing claims.

Which Sleep Number Mattress Fits Your Needs?

Begin with your normal sleeping position, the amount of surface cushioning you need, and whether you will use connected features. The air system changes underlying firmness, but it cannot replace a thick comfort layer. Lowering the air setting may reduce shoulder pressure, yet it can also let the hips sink farther and make the edge feel weaker.

ComfortMode is the value pick, while ComfortMode Lux is the better starting point for people who want more cushioning but no app. Side sleepers should focus on comfort-layer depth instead of assuming a very low air setting will provide enough pressure relief. Back sleepers and combination sleepers who want more response should compare ComfortNext Lux with the standard ComfortNext.

ClimateCool earns its premium only when active cooling solves a nightly problem. Persistent hot sleepers are the clearest fit. Climate360 is a different decision because its price also buys active warming and a smart adjustable base. Compare the full packages, not just the mattress names.

Quick picks

  • Lowest entry price: ComfortMode

  • More cushioning without an app: ComfortMode Lux

  • Lowest-priced connected model: ComfortNext

  • Best construction upgrade: ComfortNext Lux

  • Deepest non-Climate build: ComfortNext Ultra

  • Active cooling: ClimateCool

  • Separate heating, cooling, and base articulation: Climate360

What to Know Before You Buy

Adjustable firmness is useful, but it does not make every model feel alike. At very soft settings, the air-supported structure can become easier to notice and the perimeter may feel less stable. A deeper comfort system softens that sensation, but it also raises the price and changes how quickly adjustments are felt.

  • ComfortNext and Climate features depend on power, compatible devices, and a working control system. Pumps, hoses, sensors, and bases also add more possible service points than a conventional mattress.

  • Temperature claims describe controlled product performance, not a guaranteed change for every sleeper or bedroom. Room temperature, bedding, and the mattress pad all affect the result.

  • The 100-night mattress trial does not make adjustable bases returnable. A mattress received through the one-time exchange becomes final sale and does not receive another trial.

  • Current purchases carry a 10-year limited warranty: two years of full coverage followed by eight years of limited coverage. Read the cost-sharing terms, not only the headline length.

  • Sleep Number entered a court-supervised sale process in 2026, and a court approved the sale of its operating business to a Sleep Country Canada subsidiary in July. Sleep Number said stores, online orders, deliveries, and warranty service were continuing. Buyers should still save every order document and the policy issued on the purchase date.

  • The seven current mattresses have not completed our hands-on test process and do not have Dweva performance scores.

How Sleep Number Compares with Adjustable-Air Alternatives

Saatva Solaire is the closest direct adjustable-air alternative. Its 13-inch mattress provides 50 firmness settings on each side in Queen and larger sizes, and the $4,599 Queen base price includes remotes, in-room delivery, and setup. A 365-night trial and lifetime limited warranty are stronger headline policies than Sleep Number's, but Solaire does not offer Sleep Number's sleep insights or active temperature system. It competes most directly with ComfortNext Ultra.

Airpedic 650 and Airpedic 850 emphasize mechanical customization. Their six-chamber systems create three adjustable zones on each side, allowing the lumbar area to be changed separately from the head-and-leg zones. That is more granular than one firmness adjustment per sleeper and suits people focused on zoned support rather than sleep tracking. Promotions change often, so compare the Queen checkout price, delivery, and any base as a complete order.

Personal Comfort takes the familiar dual-air approach and offers 45 firmness settings, separate-side control, a 120-night trial, and a 25-year limited warranty. The trial requires at least 45 nights before a return can be approved. Its broad range can undercut or exceed ComfortNext pricing, so comfort-layer depth, controller features, and return costs matter more than the number of settings alone.

How to Dial In Your Sleep Number Setting

  • Begin near the middle of the firmness range and change the setting by five or 10 points at a time.

  • Keep each comfortable setting for three to five nights. One evening rarely shows how your back, hips, and shoulders will respond over time.

  • If you use an adjustable base, choose the head and foot position first. Then fine-tune the mattress because articulation changes how your weight is distributed.

  • Keep the same pillow and bedding while comparing settings so several variables do not change at once.

  • For shoulder pressure during side sleeping, lower the setting slightly. Raise it again if the hips sink too far or the lower back feels unsupported.

  • Price the complete order before paying, including the mattress, required or optional base, delivery, remote, and every final-sale item.

FAQs

Are the Sleep Number c2, c4, p6, and i10 still current models?

No. They belong to the previous smart-bed lineup and no longer appear among Sleep Number's seven current shopping options. Official support information remains available for owners.

Did the new models directly replace the c2, c4, p6, and i10?

No. Sleep Number reorganized the range around comfort depth, connected features, microcoils, and temperature control. Compare the current specifications and complete package price rather than treating one new bed as an exact successor.

Does changing the Sleep Number setting really change support?

Yes. In our legacy-model testing, the clearest change appeared beneath the hips and lower back. A higher setting reduced midsection sink, while a lower setting eased shoulder pressure for some side sleepers. The comfort layers still determine how that change feels at the surface.

Is the 100-night trial straightforward?

The mattress receives a 100-night trial, but the full order may not. Adjustable bases, display products, and upholstered furniture are final sale. A mattress obtained through the one-time exchange also becomes final sale and does not receive a new trial.

How long is the current Sleep Number warranty?

Current mattresses have a 10-year limited warranty with two years of full coverage and eight additional years of limited coverage. Older beds may have different terms based on the purchase date.

Is Sleep Number still operating after its 2026 sale process?

Yes. When the court approved the sale of Sleep Number's operating business in July 2026, the company said online and in-store sales, deliveries, and warranty service were continuing. Keep the receipt, warranty, and return policy supplied with any new order.

Our Testing Team

Chris Miller

Lead Tester

Chris oversees the full testing pipeline for mattresses, sofas, and other home products. He coordinates the team, designs scoring frameworks, and lives with every product long enough to feel real strengths and weaknesses. His combination-sleeping and mixed lounging habits keep him focused on long-term comfort and support.

Marcus Reed

Heavyweight Sofa & Mattress Tester

Marcus brings a heavier build and heat-sensitive profile into every test. He pushes deep cushions, edges, and frames harder than most users. His feedback highlights whether a design holds up under load, runs hot, or collapses into a hammock-like slump during long gaming or streaming sessions.

Carlos Alvarez

Posture & Work-From-Home Specialist

Carlos spends long hours working from sofas and beds with a laptop. He tracks how mid-back, neck, and lumbar regions respond to different setups. His notes reveal whether a product keeps posture neutral during extended sitting or lying, and whether small adjustments still feel stable and controlled.

Mia Chen

Petite Side-Sleeper & Lounger

Mia tests how mattresses and sofas treat a smaller frame during side sleeping and curled-up lounging. She feels pressure and seat-depth problems very quickly. Her feedback exposes designs that swallow shorter users, leave feet dangling, or create sharp pressure points at shoulders, hips, and knees.

Jenna Brooks

Couple Comfort & Motion Tester

Jenna evaluates how well sofas and mattresses handle real shared use with a partner. She tracks motion transfer, usable width, and edge comfort when two adults spread out. Her comments highlight whether a product supports relaxed couple lounging, easy repositioning, and quiet nights without constant disturbance.

Jamal Davis

Tall, Active-Body Tester

Jamal brings a tall, athletic frame and post-workout soreness into the lab. He checks seat depth, leg support, and surface responsiveness on every product. His notes show whether cushions bounce back, frames feel solid under long legs, and sleep surfaces support joints during recovery stretches and naps.

Ethan Cole

Restless Lounger & Partner Tester

Ethan acts as the moving partner in many couple-focused tests. He shifts positions frequently and pays attention to how easily a surface lets him turn, slide, or return after short breaks. His feedback exposes cushions that feel too squishy, too sticky, or poorly shaped for real-world lounging patterns.
