The coldest Casper, and the softest: six cooling bands over a plush 14-inch hybrid
The Casper Snow Max is the cooling flagship and the most cushioned bed Casper makes: fourteen inches, a plush 3 out of 10 (Casper's own Medium-Soft), with six aluminum graphite HeatDelete bands and Zoned Support Max with Align+ over a flex coil core. It is built for the hot sleeper who also wants to sink in, two things that usually fight each other, because soft beds wrap the body and trap heat. This one is engineered to do both at once.
Three-phase cooling, double the bands of the standard Snow
Where the standard Snow runs three HeatDelete bands, the Snow Max runs six, plus more phase-change material and the QuickCool cover. Casper calls it three-phase Snow Technology, and the stages stack: the QuickCool cover feels cool the instant your skin meets it, phase-change material in the comfort layer pulls heat as you drift off, and the six aluminum graphite bands give trapped heat a path out of the bed for twelve-plus hours. The flex coil core moves air through the mattress instead of letting heat pool the way an all-foam bed can. The surface feels soft on contact and stays cool through the night: you sink in, but not through.
Seven-zone Align+ support under all that cushion
The plush needs real support, so the Snow Max uses Zoned Support Max with Align+: seven support zones, firmer where your hips need to stay level and more giving where your shoulders drop in, so the soft surface still keeps your spine aligned. It is plush done with engineering, not just more foam. The flex coil core anchors it and firms the edge. If past soft beds have left your back sore, this is the part to lie down and feel for, and the part the Mattress Overstock team will show you first.
Who it suits, and who should skip it
The clearest fit is the hot side sleeper who wants plush: maximum cooling plus a deep surface for the shoulder and hip. It also suits anyone who loves luxury softness but has been burned by sleeping hot, since this is the one Casper bed that does both. Heavier side sleepers do well because the coil core carries weight under the deep foam, so you sink in, not through. Couples get coils that isolate movement and a firmer edge that keeps the whole bed usable. If you sleep best on a firm surface, though, a 3 out of 10 will read too soft, and a firmer model in the lineup is the better call.
Snow Max, Snow, or Dream Max?
The standard Casper Snow is a cooling medium at twelve inches with three HeatDelete bands; the Max is softer, taller at fourteen inches, and cooler still with six bands and more phase-change material. If you sleep hot and want plush, the Max is the one. If you want plush without the cooling premium, compare the Dream Max: both are tall, plush hybrids, but the Snow Max layers the six-band cooling on top. It sits tall, so plan on deep-pocket sheets (fourteen inches and up). See the full Casper lineup.
Living with it over time
The foams are CertiPUR-US certified, and the Snow Max carries Casper's 10-year limited warranty against manufacturing defects, honored on every bed Mattress Overstock sells as an authorized dealer. It works on a platform, a slatted base (roughly three-inch gaps or less), a solid foundation, or an adjustable base.
Ten minutes beats ten reviews
The flagship is the one to test against its siblings. The Snow Max is on the floor across the five Mattress Overstock showrooms in Kentucky (Lexington on Nicholasville Road, Richmond, Georgetown, London, and Somerset), next to the Snow and the Dream Max so you can feel the steps, no appointment needed. Because every associate on the floor earns the same no matter which brand you choose, the guidance is honest and never pushed. The 100-night trial holds at full length when you buy from a local authorized dealer, delivery and setup are free, and the old mattress leaves with the team.

What makes this mattress different
Six Aluminum Graphite Cooling Bands
Six HeatDelete bands shuttle trapped heat out of the bed for 12-plus hours, double the standard Snow's three. The coolest system Casper builds.
Three-Phase Snow Technology
Cooling bands, extra phase-change material, and the QuickCool cover work in sequence: cool on contact, then cool all night, not just at lights-out.
Plush 3/10, Medium-Soft Feel
Casper's softest mattress and its own Medium-Soft label. A deep, luxurious surface your shoulder and hip settle into.
Zoned Support Max with Align+
Seven support zones firmer under the hips, softer under the shoulders, so the plush surface still keeps your spine level.
QuickCool Cover
A knit cover infused with phase-change material that pulls heat the instant your skin touches it, over the deep comfort layers.
Flex Coil Core, Reinforced Edge
Responsive coils carry weight under the soft foam, move air through the bed, and firm the perimeter so you use the whole surface.
100-Night Home Trial
The same 100-night trial Casper offers, held at full length when you buy from a local authorized dealer.
10-Year Warranty, CertiPUR-US Foams
Casper's 10-year limited warranty on manufacturing defects, honored on every bed Mattress Overstock sells; foams are CertiPUR-US certified.
The coolest, plushest Casper, layer by layer
From the top down, the Snow Max stacks Casper's most aggressive cooling over a deep plush surface and a coil core:
- QuickCool cover. A knit infused with phase-change material that feels cool the instant your skin meets it.
- Six aluminum graphite HeatDelete bands. Double the standard Snow's three, they give trapped heat a path out of the bed for 12-plus hours, the first stage of three-phase Snow Technology.
- Deep zoned comfort foam with extra phase-change material. A plusher comfort layer than the Snow, with more cooling material worked in so the surface stays soft and cool together.
- Zoned Support Max with Align+. Seven support zones tune firmness across the bed, firmer where your hips need to stay level, softer where your shoulders drop in, so a soft surface still holds your spine straight.
- Flex coil core. Responsive coils carry the plush layers, move air through the bed, and firm the edge.
- Durable base. Anchors the coil unit and squares the perimeter.
Fourteen inches, plush (3 out of 10, Casper's own Medium-Soft), backed by the 100-night trial and Casper's 10-year warranty. Casper does not publish every layer thickness for this model, so the architecture is described, not measured.
The plush, coolest Casper, and who should skip it
Hot side sleepers. The headline fit. Six cooling bands and the QuickCool cover handle the heat while the deep surface cradles your shoulder and hip. If you sleep hot and side, start here.
Plush-and-cool seekers. Soft beds usually wrap the body and trap heat. This is the one Casper engineered to stay cushioned and cool at the same time, so luxury softness no longer means waking up sweating.
Heavier side sleepers. The flex coil core carries weight under the deep foam, so you sink in, not through, and the surface keeps its plush feel rather than bottoming out.
Couples. Individually wrapped coils isolate partner movement and the reinforced edge keeps the whole mattress usable, so one person turning over does not wake the other.
Combination sleepers who like soft. The coils give the soft surface enough lift to turn and reposition easily, instead of feeling stuck the way an all-foam plush bed can.
Firm sleepers and most stomach sleepers, look elsewhere. A 3 out of 10 will read too soft, and stomach sleepers tend to sink at the hips and wake up sore. A firmer model in the Casper lineup is the honest call, and the Mattress Overstock floor will point you to it.

Frequently asked questions
How soft is the Casper Snow Max?
Plush, about 3 out of 10, which is Casper's own Medium-Soft label and the softest bed in the line. Zoned Support Max with Align+ keeps it aligned underneath, so soft does not mean unsupported.
Is it the coolest Casper mattress?
Yes. It runs six aluminum graphite HeatDelete bands, double the standard Snow's three, plus extra phase-change material and the QuickCool cover. Casper calls this three-phase Snow Technology, and it is the most cooling system the brand builds.
What is the difference between the Snow Max and the standard Snow?
The Snow is a cooling medium at 12 inches with three HeatDelete bands. The Snow Max is softer, taller at 14 inches, and cooler, with six bands and more phase-change material. Choose the Max for plush plus maximum cooling.
How does the cooling actually work?
In three stages. The QuickCool cover feels cool on contact, phase-change material in the comfort layer pulls heat as you fall asleep, and six HeatDelete bands give trapped heat a path out of the bed for 12-plus hours. The coil core adds airflow on top of all of it.
Is a bed this soft still supportive?
Yes. Zoned Support Max with Align+ uses seven support zones, firmer under the hips and softer under the shoulders, and the flex coil core holds the plush surface up. If past soft beds have left your back sore, this is the part to lie down and feel for.
How tall is it, and will my sheets fit?
Fourteen inches. Plan on deep-pocket sheets rated for 14 inches and up so they tuck and stay put.
Do I need a special foundation or base?
No. A platform, a slatted base with roughly 3-inch gaps or less, a solid foundation, or an adjustable base all work.
Snow Max or Dream Max?
Both are tall, plush hybrids. The Snow Max adds Casper's three-phase cooling on top. If you sleep hot, choose the Snow Max. If cooling is not a priority, the Dream Max is the plush all-rounder for less.
What is the trial and warranty, and how do returns work?
You get the same 100-night trial Casper offers, held at full length when you buy from Mattress Overstock as an authorized dealer, plus Casper's 10-year limited warranty on manufacturing defects. If it is not right, Mattress Overstock exchanges it for store credit toward a bed of equal or greater value rather than a cash refund.
