Find your best fit

Start with your buying decision

Start with these listed features, advertised feel, and seller terms, then consider how they fit your preferences. The detailed comparison below covers shared features, differences, and questions to confirm before choosing either mattress.

Literal temperature-control difference

Sleep Number ClimateCool Mattress: Active cooling up to 15° cooler on each side
Sleep Number Climate360 Smart Bed: Adjustable temperature up to 30° cooler to warmer on each side

Why it matters: ClimateCool directly addresses overheating and lets partners receive active cooling on their own side. Climate360 expands the use case in both directions: one sleeper can seek stronger cooling while the other uses warmth, and each side can follow its own setting. The upgrade makes sense for couples with opposite temperature preferences, cold sleepers who want bed warming, or shoppers whose comfort changes by season. If both sleepers mainly want relief from heat, ClimateCool solves that need at a much lower total.

Literal cooling-material and program difference

Sleep Number ClimateCool Mattress: Built-in cooling materials + active cooling
Sleep Number Climate360 Smart Bed: 52% more built-in cooling + active cooling-and-warming programs

Why it matters: Climate360 combines a larger passive cooling package with powered routines that can change the bed's temperature over the night. That is useful when you want the surface cooled before sleep and adjusted later without waking to make a manual change. ClimateCool keeps the simpler proposition: move heat away and actively cool both sides. A shopper who does not need warming or scheduled temperature changes can keep $3,749.25 without giving up active cooling.

Literal contouring and profile difference

Sleep Number ClimateCool Mattress: 12 inches; contouring relief across the whole body
Sleep Number Climate360 Smart Bed: 13 inches; ultimate contouring relief across the whole body

Why it matters: Both beds spread their contouring focus across the body rather than naming only one contact area. Climate360 adds one inch and moves to Sleep Number's highest contouring description, which benefits side sleepers and plush-comfort shoppers who want a deeper pressure-relieving surface. ClimateCool is likely the better fit when you prefer a slightly slimmer feel and are buying primarily for temperature control rather than maximum cushioning.

Which one fits you

Our buying recommendation

Buy ClimateCool when active cooling is the clear objective. It gives each side up to 15 degrees of cooling, adjustable firmness, whole-body contouring, and an included foundation while saving $3,749.25. Upgrade to Climate360 when you want a complete temperature-and-position system: stronger cooling, warming, overnight programs, maximum contouring, and an included smart adjustable base. The premium is easiest to justify for couples with opposite temperature preferences who also want articulation. ClimateCool is the confident buy when both sleepers want a cooler bed and a flat foundation is enough.

Sleep Number ClimateCool vs Climate360: What the Extra $3,749.25 Buys

ClimateCool and Climate360 both adjust firmness on each side and use powered temperature technology, but their prices do not describe mattress-only peers. ClimateCool is a 12-inch active-cooling mattress priced at $3,937.50 with a foundation included; Sleep Number says it can feel up to 15 degrees cooler on each side. Climate360 is a 13-inch smart sleep system priced at $7,686.75 with its adjustable base included; each side can be set across a range reaching up to 30 degrees cooler to warmer. The $3,749.25 premium buys warming as well as stronger cooling, deeper contouring, more built-in cooling material, programmed temperature control, and an included articulating base. Choose ClimateCool when cooling is the problem; choose Climate360 when two sleepers want separate temperature programs and adjustable positioning in one system.

Included support system and current Queen price

Sleep Number ClimateCool Mattress: $3,937.50 current / $5,250 reference; foundation included; adjustable-base options available
Sleep Number Climate360 Smart Bed: $7,686.75 current / $10,249 reference; smart adjustable base included

Why it matters

The $3,749.25 difference cannot be treated as the price of extra mattress material alone. Climate360's total includes an articulating smart base, while ClimateCool includes a flat foundation and lets you price an adjustable base separately. Climate360 is easier to justify when you already want head-and-foot positioning and would otherwise buy a premium base. ClimateCool delivers the lower complete-bed price when a flat foundation fits your setup.

Buy-with-confidence terms

Sleep Number ClimateCool Mattress: 100-night mattress trial; 30-night minimum; $250 standard-area return pickup fee; optional adjustable bases are generally final sale
Sleep Number Climate360 Smart Bed: 100-night trial covers the Climate360 Mattress and Base together; 30-night minimum; $250 standard-area return pickup fee

Why it matters

Climate360 receives a meaningful exception to Sleep Number's usual final-sale rule for adjustable bases: its Mattress and Base are covered together by the direct 100-night trial. That gives online shoppers a clearer path to test the integrated system at home. ClimateCool's included foundation follows the mattress purchase, but a separately selected adjustable base is generally final sale. Both trials begin at delivery, require 30 nights, permit one return or exchange, and make an exchanged product final sale without a new trial.

Who benefits from each mattress?

Use the differences above to match the mattress to the way you sleep. Each model has a clear reason to buy. When one costs less, choose it if it already delivers the feel, support, and temperature control you want. Pay more when the added material or feature gives you a benefit you expect to notice every night.

Choose Sleep Number ClimateCool Mattress if:

You and your partner primarily sleep hot and want active cooling on each side without paying for warming programs.
A flat included foundation suits your room, or you prefer to choose and price an adjustable base separately.
You want whole-body contouring and Sleep Number adjustability in a complete setup that currently costs $3,749.25 less.

Choose Sleep Number Climate360 Smart Bed if:

You and your partner have different temperature needs, including a sleeper who wants warmth or stronger cooling.
You want programmed overnight temperature changes instead of a cooling-only system.
You already value head-and-foot positioning, maximum contouring, and an integrated smart adjustable base covered with the mattress by the 100-night trial.
