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.

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.
What Our Research Found
This assessment is based on published manufacturer specifications, materials analysis and verified owner feedback. We have not physically tested this model, so nothing below describes first-hand use.
The ComfortNext is where Sleep Number's 2026 lineup gets seriously impressive.
At 12 inches, it has the profile of a premium traditional mattress, but with the adjustability that traditional mattresses can't match.
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.

Sleep Position Analysis
Side Sleepers
The Sleep Number ComfortNext's softer feel (5/10) may provide more cushioning for side sleepers.
Back Sleepers
The Sleep Number ComfortNext's listed firmness of 5/10 may suit back sleepers seeking a medium-to-firm surface. Spinal alignment and hip support have not been objectively measured for this model unless documented test results appear above.
Stomach Sleepers
At 5/10 firmness, the Sleep Number ComfortNext may be too soft for stomach sleepers. Stomach sleepers may want to compare a firmer model, especially if they notice uncomfortable hip sinkage.
Combination Sleepers
The Sleep Number ComfortNext is an adjustable airbed, so responsiveness depends on the pressure you set rather than on foam or coils. Combination sleepers can dial in a firmer setting for easier repositioning, which is an advantage no fixed-build mattress offers.
Which Sleep Number ComfortNext Model Should You Buy?
The ComfortNext is where Sleep Number's lineup adds active temperature management — a multi-zone pressure-relief stack and a temperature-regulating layer over the standard dual-air core. It's the entry point for buyers who sleep hot.

Choose the Brooklyn Bedding ThermoBalance if: You want excellent passive cooling at less than half the price.
Read the full Sleep Number ComfortNext vs. Brooklyn Bedding ThermoBalance comparison →The temperature layer, explained
The ComfortNext's active temperature layer moves air through the comfort stack to carry heat away from the sleeper — a middle step between passive cooling covers and the Climate360's full active heating-and-cooling system. It cools; it doesn't warm.
In practice it takes the edge off for moderate hot sleepers. Severe night sweaters should look at the ClimateCool or Climate360, and cool-sleeping buyers should save $1,400 with the ComfortMode.
Multi-zone pressure relief
Above the air chambers, the ComfortNext adds zoned foam that's softer at the shoulders and firmer under the lumbar — a meaningful upgrade for side sleepers that the ComfortMode line lacks.
Combined with the adjustable air, this makes the ComfortNext the most position-versatile bed in the mid-lineup: set the air for overall firmness, and let the zoning fine-tune pressure points.
