How the Casper Mattress is Made
The Casper Mattress is made of several layers of foam that provide comfort and support. Read the following sections to learn how the mattress is made.
Cozy Knit Cover
The comfort starts with the cozy knit cover. Made of soft, stretchy fabric, the cover enhances the cushioning effect of the foam layers.
Cooling Foam Layer
A layer of Casper SignatureTM foam provides bounce as well as a little cushioning. Made with AirScape® Technology, the foam is perforated to let air circulate. The result is a responsive, cooler mattress that doesn’t retain body heat and won’t give you that sinking feeling.
Memory Foam with ZonedTM Support
Premium Memory Foam contours to the body’s natural shape. But that’s not all. This foam layer features ZonedTM support in 3 areas to ensure spinal alignment. The Premium Memory Foam offers pressure relief and support where it’s needed most: the spine, shoulders, and hips. Your body is cradled without sacrificing support.
Firm Foam Base
Made of firmer foam, the Casper Mattress base provides support across the entire mattress. It’s a durable, stable layer that prevents sagging and enhances the lifespan of the mattress. This layer enhances the targeted support and responsiveness of the previous foam layers.
Your Choice of Mattress Sizes
Comfort and support features are one thing. A mattress must also be a good fit for your home and your sleep preferences. The Casper Mattress is available in standard mattress sizes from Twin to King. All sizes are 10” thick with the following dimensions:
- Twin: 37.5” x 74.5”
- Twin XL: 37.5” x 74.5”
- Full: 52.5 x 74.5
- Queen: 59.5” x 79.5”
- King: 75.5” x 79.5
Firmness Rating: Medium
The Casper Mattress has a medium feel that balances comfort and support. That puts it at 5 on a scale of 1 to 10 with 10 the firmest. A medium mattress provides just enough support along with just enough cushioning.
Casper Mattress Review: Benefits and Any Drawbacks
Now that you know how the Casper Mattress is made, let’s look at what it’s like to sleep on. We have researched and reviewed the Casper Mattress. In this section, we discuss what we believe are its benefits as well as any drawbacks.
Balance of Pressure Relief and Support
At the end of the day, the foam layers soothe tired pressure points and provide support. First, the Casper SignatureTM Mattress combines responsiveness with just the right amount of cushioning. Next, the Premium Foam layer contours to your shape and provides ZonedTM support in three key areas: spine, shoulders, and hips. The cozy knit cover adds a final touch of soft comfort to the mattress.
We think you’ll like how the two layers cradle your body to sleep. With targeted support, your midsection won’t drop out of alignment. Plus, the firmer foam base distributes support and adds stability over the entire mattress. This balance of pressure relief and support helps you sleep comfortably through the night and wake up without morning aches.

Works for Most Sleep Positions
It’s nice to have a mattress that is comfortable for your preferred sleep position and will still work if your preferences change. Thanks to its pressure relief and targeted support, the Casper Mattress is suitable for most sleep styles. If you sleep on your side, the foam layers will support and contour to your spine, shoulders, and hips. Back and stomach sleepers may find helpful midsection support from the ZonedTM memory foam and responsive SignatureTM foam.
Temperature Control
If you tend to sleep hot, we think you’ll appreciate the AirSpace® cooling in the SignatureTM foam layer. Unlike traditional foam layers, it won’t trap body heat. The Casper Mattress foam is perforated to allow air flow. Instead of retaining body heat, the foam lets the air carry away the heat to keep you cool and comfortable.

Not Too Soft and Not Too Firm
With a medium feel, the Casper Mattress strikes a balance between firm and soft. Couples who have differing sleep preferences may find it an ideal solution. The responsive SignatureTM foam and firmer foam base work with the ZonedTM memory foam to provide just enough contouring and support.
CertiPUR-US Safety Certification
We’ve reviewed what goes into the Casper Mattress, but we think you’ll be just as impressed with what it doesn’t have. The mattress is made with CertiPUR-US certified foams, which means that the foams are free of harsh chemicals. You can have peace of mind knowing that your mattress is made with safe materials, without formaldehyde, ozone depleters, heavy metals, and other harmful substances.
Mattress In a Box
Another thing we like about the Casper Mattress is it’s conveniently shipped in a box. The mattress is compressed and rolled to fit in a container. It arrives at your door, even if you’re at work or running errands.
The Casper website notes that when you unbox the Casper Mattress, it expands within minutes. Thanks to the mattress’s water-based adhesives and CertiPUR-US certified foams, there is little or no off-gassing or “new mattress smell.” The mattress is ready for use that night.
100-Night Trial
When you buy a new mattress, it takes time to adjust and decide if it’s a good fit. In fact, the typical break-in period for a new mattress is about 30 days. Fortunately, the Casper Mattress comes with a 100-night trial period that begins on the date of delivery. That gives you more than three months to literally sleep on it.
After an initial 30-day adjustment period, you can return the mattress for a full refund within the trial period. Casper will arrange a pickup and, if possible, will recycle the mattress or donate it to a local charity.
10-Year Limited Warranty
Even a top-rated mattress in Canada can have occasional issues. The Casper Mattress is backed by a 10-year limited warranty. During the warranty period, Casper will repair or replace a mattress that is found to have defects caused by poor workmanship or materials. Examples of covered def include cracked foam or indentations deeper than 1”.
A company may change its warranty policies at any time, so it’s always wise to read updated warranty terms before you buy.
Casper Mattress Review: Concluding Thoughts
The Casper Mattress offers many features that one would expect from a top-rated mattress in Canada. The balance of support and cushioning creates a mattress that works for most sleep styles. Our team is impressed with the way the foam layers cradle the body while providing targeted support.
The soft knit cover is the closest layer to the skin. It stretches over the contouring foam layers, which provide soothing pressure relief and support. The Casper SignatureTM foam is responsive enough to maintain spinal alignment and prevent the midsection from sinking too low. The memory foam with ZonedTM support continues the balance of comfort and support.
With a medium feel, the Casper Mattress is suitable for a wide range of sleep preferences. The mattress provides support where you need it most, yet you won’t feel as though you’re lying on top of the mattress. You can sink into the contouring memory foam yet still keep your spine, shoulders, and hips aligned. We think that side sleepers will find the pressure relief ideal. Back and stomach sleepers may also find the targeted support comfortable.
The Casper Mattress helps keep you cool, too, thanks to AirSpace® temperature control. Thanks to this technology, air circulates through perforated foam and carries away body heat. This prevents the foam from trapping heat as it conforms to your body.
All of this comfort is provided by safety certified materials. All foams in the Casper Mattress meet strict CertPUR-US standards. That means the foams are free of harmful substances, such as formaldehyde, mercury, lead, and ozone depleters. The Casper Mattress is safe for you and for the environment.
We also think you’ll appreciate the 100-night sleep trial. It gives you more than three months to decide if the Casper Mattress is right for you. Plus, if you return the mattress, a local char may benefit from it. The 10-year limited warranty is another way that Casper stands by its product.
