Casper Snow Hybrid Review: Cooling Performance Tested (2026)
Casper's premium cooling mattress uses HeatDelete bands and a phase-change material cover to actively pull heat away from your body. It is one of the most technologically advanced cooling solutions in the passive mattress category.
Quick Verdict
One-sentence verdict: The best passive cooling mattress for night sweats, combining HeatDelete bands with PCM technology for active heat removal without a powered system.
Who This Mattress Is For
Good fit
- Night sweat sufferers who want the most advanced passive cooling
- Side and back sleepers between 130 and 230 lbs
- People who want phase-change material for active heat absorption
- Casper brand loyalists upgrading from the Original or Wave
- Couples where one partner runs hot (Snow handles partner temperature independently)
Not ideal
- Stomach sleepers who need firm support (5.5/10 may be too soft)
- Sleepers over 230 lbs who need extra support
- Budget shoppers (at $1,995, it is the second most expensive passive option)
- People who want firmness options (Snow is one-firmness only)
Cooling Technology Breakdown
HeatDelete Bands
The HeatDelete bands are Casper's most significant cooling innovation. These are strips of highly conductive material embedded within the foam layers that function like heat sinks in a computer. They draw thermal energy away from the sleep surface and channel it toward the mattress edges and the coil layer below. This creates directed heat flow rather than relying on passive absorption alone.
Phase-Change Material (PCM) Cover
The Snow's cover is infused with phase-change material that transitions between solid and liquid states at approximately 80 degrees Fahrenheit. When your body temperature pushes the cover above this threshold, the PCM absorbs the excess heat as it changes state. This creates a noticeable cooling effect at the surface, which is the first point of contact with your body. PCM is one of the most effective single cooling technologies available.
AirScape Perforated Foam
Beneath the cover, the AirScape foam layer features thousands of perforations that increase airflow through the comfort layer. Standard memory foam is a dense, closed-cell material that traps heat. By perforating the foam, Casper creates channels for air movement that would not otherwise exist. This works alongside the HeatDelete bands to move heat downward toward the coil layer.

Frequently Asked Questions
Is the Casper Snow good for night sweats?▾
The Casper Snow is one of the best mattresses for night sweats caused by sleeping too warm. The HeatDelete bands actively pull heat away from your body, and the PCM-infused cover absorbs excess warmth. If your night sweats are medically caused, a mattress alone may not be sufficient, but for heat-related sweating the Snow is one of the most effective options.
What are HeatDelete bands?▾
HeatDelete bands are Casper's proprietary cooling technology. They are strips of highly thermally conductive material embedded in the foam layers. They work like heat sinks in a computer, drawing warmth away from your body and channeling it toward the edges and coil layer below where it can dissipate. This provides active heat management beyond what passive gel foam alone can achieve.
How does the Casper Snow compare to the Brooklyn Bedding Aurora?▾
Both are top-tier cooling mattresses. The Aurora scores slightly higher (9.2 vs 9.0) and costs $300 less for a queen. The Aurora offers three firmness options while the Snow comes in one. The Snow uses HeatDelete bands and PCM that may work better for night sweats specifically. Choose the Aurora for firmness flexibility and value, the Snow if night sweats are your primary concern.
Is the Casper Snow too soft for back sleepers?▾
At a 5.5/10 firmness, the Snow works for most back sleepers between 130 and 230 lbs. Back sleepers over 230 lbs may find it too soft and should consider the WinkBed Firmer or Brooklyn Bedding Aurora Firm. Stomach sleepers may also want more support than the Snow provides.
