Casper Snow Cooling Mattress Construction
The Casper Snow contains 7 layers of innovative materials designed to keep you cool and comfortable. We provide construction details in the sections below.
CoolTouch Cover
The Casper Snow cooling trend starts with the CoolTouch cover. Made from specially designed cooling yarns, the cover draws heat away from your body. According to the Casper website, the soft knit cover pulls away heat 20% faster than a mattress without the cover.
Casper Signature Foam with Cooling Phase Change Material
A 1” layer of Casper Signature Foam is enhanced with innovative cooling materials. Cooling PCM (phase change material) and AirScape® Technology promote air flow and draw away heat. The result is a foam layer that keeps you cool and won’t retain heat.
Casper Signature Foam with AirScape® Technology
An additional layer of Casper Signature Foam with AirScape® Technology allows even more air circulation. This 1.5” foam layer provides soothing and cooling comfort.

HeatDeleteTM Bands
Nestled between the layers of Signature Foam is a series of Cooling HeatDeleteTM Bands. These innovative bands keep you cool for 12 or more hours by continually drawing heat away from your body.
Premium Memory Foam with Zoned SupportTM
The next layer performs double duty by relieving pressure and targeting support. Two inches of Premium Memory Foam includes three areas of enhanced support to maintain spinal alignment and relieve pressure. The mattress is softer under your shoulders and firmer under your hips, waist, and lumbar area.
Pocket Coil Layer
A layer of 6” individually wrapped or pocketed coils provides edge to edge coverage and support. The polypropylene-wrapped steel coils are reinforced around around the perimeter to of the mattress to provide edge support. The pocket coils allow air circulation, keeping you cool all night.
The coil layer contains hundreds of springs, ranging from 458 in the twin size Casper Snow mattress to 990 in the California King size.
Foam Encasement Tub
A 7” layer of firm foam encases the coil layer. This foam encasement tub enhances edge support to prevent sagging and make it easier to get in and out of bed.
Your Choice of Mattress Size
There’s a Casper Snow mattress size to fit your home and sleep preferences. The mattress is available in the following dimensions:
- Twin XL: 38″ W x 80″ L x 12″ H
- Full: 53″ W x 75″ L x 12″ H
- Queen: 60″ W x 80″ L x 12″ H
- King: 76″ W x 80″ L x 12″ H
- California King: 72″ W x 84″ L x 12″ H
Casper Snow Firmness Level
The multiple layers of foam combine with the steel coil layer to provide a medium feel. That makes the Casper Snow a great choice for side sleepers and lighter weight sleepers. It’s also a good solution for couples who have differing comfort preferences.
Mattress in a Box
After you purchase your Casper Snow mattress, it is rolled and compressed to fit in a shipping container. The mattress is delivered to your door in a box, even if you’re at work or running errands. Casper ships its mattresses for free to most of Canada.
Casper Snow Cooling Mattress Review: Pros and Any Limitations
After our research and review, our team believes that the Casper Snow mattress offers many pros. We’ll also let you know about any limitations we found.
Advanced Cooling Technologies
From AirScape® Technology to HeatDeleteTM bands, the Casper Snow mattress offers advanced cooling capabilities. The materials pull air away from your body and allow airflow to carry heat away from the mattress. Thanks to the HeatDeleteTM bands, the mattress stays cool for 12 hours or longer. That’s enough time for a restful, comfortable sleep.
Even the steel pocket coils and soft knit cover help keep you cool. Both layers promote air flow and prevent heat retention. If you tend to sleep hot, we think you’ll be impressed with the cooling technologies in the Casper Snow mattress.
Zoned SupportTM and Pressure Relief
We’re impressed with the balance of pressure relief and support in the Casper Snow, even within a single layer. The 2” Premium Memory Foam provides pressure relief and support where you need it most. Under your shoulders, softer foam relieves pressure. The memory foam is also reinforced to provide Zoned SupportTM for your hips, waist, and lower back. Side sleepers may find this targeted support and pressure relief especially comfortable.
We like how the two layers of Casper Signature Foam provide additional pressure relief. The 6” reinforced pocket coils offer ample support as well as contouring and responsiveness. All of the layers work together to create a medium feel that cradles your shape while maintaining alignment.
Nontoxic Materials
We think Canadians will like what’s not in the Casper Snow hybrid as much as what’s in it. The Casper Snow contains foams that are CertiPUR-US certified free of toxic chemicals. You can rest easy knowing that you are sleeping on memory foam that does not contain ozone depleters, formaldehyde, VOCs, and other harmful chemicals.
Wait After Unboxing
After you remove the Casper Snow from the shipping box and unroll the mattress, be prepared to wait for the mattress to fully expand. It can take anywhere from a few minutes to a few hours for the mattress to reach its full size. There may be a slight odour or “off-gassing”, which is normal with a mattress in a box. The odour should dissipate after a few hours in a well-ventilated area.

100-Night Sleep Trial
It can take at least 30 days to adjust to a new mattress, especially if you’ve had your old mattress for many years. When you buy the Casper Snow cooling hybrid, there’s no rush to decide if it’s the best cooling mattress for you. The mattress comes with a 100-night sleep trial to give you plenty of time to literally sleep on it.
Casper asks that you try the mattress for 30 days before making your decision. If you’re not happy with your purchase, you can return it for free 31 to 100 days after you receive the mattress. Casper will arrange a free pickup and issue a full refund. Whenever possible, they will donate your returned mattress to a local charity.
10-Year Limited Warranty
Casper backs its product with a 10-year limited warranty. The warranty covers manufacturer defects, such as cracked foam or visible indentations greater than 1 inch. It does not cover defects caused by improper handling or use.
If a Casper Snow mattress is found to have defects that are covered by the warranty, Casper will repair or replace the mattress. Warranty terms can change at any time, so make sure you read the warranty before buying a mattress.
Casper Snow Mattress Review: Concluding Thoughts
Casper has included advanced technologies and materials in the Snow hybrid mattress. From the Premium Memory Foam with Zoned SupportTM to the AirScape® Technology, the mattress offers support, pressure relief, and temperature control. Plus, the foams are certified free of formaldehyde, VOCs, and other toxic substances.
With the Casper Snow cooling mattress, temperature control is the star attraction. In your search for the best cooling mattress in Canada, you want to find a sleep surface that stays cool all night. That’s exactly what we found when we researched the Casper Snow. Thanks to the HeatDeleteTM Bands, the mattress stays cool for at least 12 hours. Canadians who sleep hot will also appreciate the Cooling Phase Change Material and AirScape® Technology.
The Casper Snow offers Canadians a medium feel that is not too soft and not too firm. With Zoned SupportTM and targeted pressure relief, the mattress cushions and soothes as it maintains spinal alignment. Support and comfort complement each other in the Casper Snow hybrid.
We like how Casper stands by their product with a 100-night sleep trial and 10-year limited warranty. After purchasing the Casper Snow mattress, Canadians can try the mattress risk-free for 100 nights before making a final decision. The warranty covers defects caused by poor workmanship or materials. Thanks to the sleep trial and warranty, you can have peace of mind about your mattress purchase.
