Purchasing and Returns
Unboxing and First Impressions
The Casper mattress arrives at your doorstep as a foam mattress in a compressed, compact box, wrapped in plastic — a true bed-in-a-box experience. The mattress will be ready to sleep on right away, but we recommend letting it expand for 48 hours for ideal comfort. Overall, the unboxing process was easy and hassle-free, requiring minimal effort.
Like most foam mattress products, some mild off-gassing may occur when the new mattress is first unboxed — this is normal and typically dissipates within a few hours to a day in a well-ventilated room. Using a mattress cover or removable cover mattress protector from night one is recommended to keep the Casper in optimal condition throughout the sleep trial.

Construction
The Casper mattress is built with foam layers that combine cooling features, pressure relief, and durable support layer performance. Here is a complete breakdown of the foam layers inside this all foam mattress:
1. Cooling Eco Knit Mattress Cover (Removable Cover / Machine Washable Cover)
The mattress cover is made with sustainable recycled fibres and features advanced cooling features technology built directly into the fabric. This removable cover is fully machine washable — a machine washable cover that makes ongoing mattress hygiene straightforward. The Casper’s removable cover is one of the most practical mattress cover designs available in any Canadian foam mattress, and its eco-knit construction contributes to the mattress’s overall breathability. A fire barrier is also integrated into the mattress cover design, eliminating the need for chemical flame retardants — a meaningful advantage for sleep health and indoor air quality.
2. AirScape® Cooling Foam (Top Layer / Comfort Layer)
The top layer is AirScape® cooling features foam — a responsive, open cell foam layer featuring perforations that circulate air and create a breathable mattress surface. This open cell foam construction actively prevents excess heat from accumulating at the top layer, making The Casper one of the most breathable all foam mattress options available at this price point. The open cell structure also contributes to the mattress’s low bounce management — providing enough responsiveness to prevent the “stuck” sensation common with denser polyurethane foam comfort layer designs. The AirScape® cooling features system is a core differentiator of Casper sleep technology.
3. Pressure-Relieving Premium Memory Foam (Comfort Layer / Memory Foam Layer)
The memory foam layer beneath the AirScape® foam absorbs pressure points, reduces motion transfer, and cradles the body to help you stay asleep. This comfort layer uses Casper signature foam — a premium polyurethane foam formulation with a density of at least 2.5 pounds per cubic foot, contributing to exceptional long-term durability. The memory foam layer is the heart of The Casper’s pressure relief system, providing deep foam comfort layer contouring at key pressure points including the neck, shoulders, hips, and lower back. The two layers of comfort layer — AirScape® above and memory foam layer below — work in concert to deliver a genuinely medium firm feel that suits a wider range of sleeping positions than standard polyurethane foam designs.
4. ProSupport High-Density Base Foam (Support Layer)
The support layer base is ProSupport High-Density foam — a firm foundation of polyurethane foam that delivers long-lasting support layer performance while preventing sinking and sagging. This support layer uses polyurethane foam with a density of at least 1.8 pounds per cubic foot, providing the durable foam base needed to maintain zoned support performance over the mattress’s lifetime. The ProSupport support layer also reinforces edge support across the full perimeter of the Casper mattress — a key contributor to The Casper’s impressive edge support score.
Comfort
The Casper mattress is known for its durability and comfort, as confirmed by our in-house testing. The mattress uses high-quality memory foam foam layers to create an ideal sleeping environment that offers spot-on contouring and great support for the body. The Casper signature foam and AirScape® cooling features system combine to deliver a medium firm feel that consistently helps sleepers feel well supported across all sleeping positions.
Key areas such as the neck, shoulders, back, and hips receive excellent pressure relief and pain relief from this premium foam mattress, ensuring rejuvenating sleep. The stretchable, snug removable cover provides a soft-to-the-touch sleeping surface, while the high-quality memory foam foam layers soothe you to sleep as they cradle the body. Many users describe The Casper’s zoned support system as particularly effective for relieving back pain — with firmer foam resistance under the hips providing targeted lumbar support that is rare among all foam mattress options at this price. Our performance tests confirmed high customer satisfaction with the initial comfort and lasting medium firm feel of the Casper mattress.
Firmness
This mattress review evaluates The Casper in a medium firmness level — though it is also available in Plush and Firm. The Casper Medium ranks 7 out of 10 on our firmness scale, classifying it as a true medium firm mattress. This medium firm feel provides great support and comfort for a wider range of sleeping positions than softer alternatives. According to our performance tests, the Casper mattress is characterised as best for lightweight to average-weight back sleepers and side sleepers who prefer a medium firm surface.
For strict side sleepers or heavier individuals who prefer a medium soft surface, The Casper Plush offers additional cushioning through softer foam layers. For stomach sleepers and back sleepers who want a bit firmer surface with maximum lumbar support, The Casper Firm delivers firmer foam layers and stronger zoned support for spinal alignment. The Casper One Mattress — the one mattress variant in the lineup — is designed to suit all sleep styles with a balanced medium firm feel and enough support across all body types. The Casper Select rates at 7.0/10 on the firmness scale, making it a bit firmer than the Casper Original if extra support is needed.
Motion Transfer
The Casper is a great mattress for couples or those who want to remain undisturbed while sleeping with kids or pets. Whenever we write Casper mattress reviews, we always rigorously test mattresses for motion transfer. While minor motion transfer is noticeable, The Casper performed well during performance tests evaluating surface movement — scoring an 8 out of 10 on our motion isolation performance scale. The Casper earns a great motion isolation designation for an all foam mattress in its price tier.
The memory foam layer and AirScape® open cell foam comfort layer work together to effectively absorb motion before it can travel across the mattress surface. For those who share their mattress with a partner, the Casper can still transfer slight movement — as is common with many memory foam foam mattress designs — but if you’re a deep sleeper, the motion isolation on The Casper is more than adequate for a restful night. Our Casper mattress reviews consistently rate its motion isolation performance among the best mattresses in the all foam mattress category in Canada.
Cooling
The Casper is a great mattress for hot sleepers. The improved airflow and breathability in the mattress — driven by its AirScape® open cell foam top layer and cooling features-integrated mattress cover — deliver minimal heat or sweat retention compared to standard polyurethane foam all foam mattress alternatives. The cooling features score of 8.5/10 in our performance tests reflects how effectively The Casper manages excess heat during the night.
The cooling AirScape® foam top layer uses open cell foam perforations to actively circulate air, while the cooling technology in the eco-knit mattress cover works at the sleep surface level to prevent excess heat buildup from the very first moment of contact. This combination of cooling features — open cell foam ventilation plus surface cooling technology — is why The Casper outperforms most other mattresses in its all foam mattress class for temperature management.
For hot sleepers who require more cooling features beyond what The Casper Medium delivers, Casper Canada also offers the Casper Wave Hybrid Snow — a hybrid mattress with phase change materials in the comfort layer for maximum temperature regulation. The phase change materials in the Wave Hybrid Snow model actively absorb and release heat in response to body temperature, providing sustained cooling features throughout the night.
Edge Support
The Casper bed offers good edge support, ensuring a restful sleep even closer to the mattress edge. Individuals can lie or sit comfortably on the edge without falling or slipping off, as the ProSupport High-Density Base foam support layer reinforces long-lasting edge support overall. The Casper scores 8.5/10 for edge support in our performance tests — among the highest edge support scores we’ve recorded for any foam mattress in this price tier and a genuine differentiator from similar mattresses.
This good edge support enhances the usable sleeping surface of The Casper for sleepers who tend to sleep near the perimeter or who sit on the mattress edge to dress. The high-density polyurethane foam support layer resists perimeter compression more effectively than the foam layers found in competing all foam mattress options — making The Casper’s edge support a consistent strength across our performance tests. Most sleepers who transition from other mattresses with weaker edge support notice the difference immediately.
Sinkage and Responsiveness
The Casper offers a blend of balance and support to prevent excessive sinkage. Overall, there is low bounce sinkage on The Casper, making it easy to get in and out of bed. This mattress is highly responsive and offers supportive body contouring due to the memory foam foam layers built, resulting in quick recovery from body weight and any compression. The AirScape® open cell foam top layer plays a key role in this responsiveness — its open cell structure rebounds faster than standard polyurethane foam comfort layer designs.
Overall, The Casper has adequate support for a range of sleepers, but side sleepers or those looking for a more plush feel may want to invest in the medium soft Plush version, which features softer foam layers and deeper body contouring at the comfort layer level.
How does it suit different sleeping positions?
Side Sleepers
As side sleepers require more cushioning around the neck and shoulder area, memory foam foam mattress designs are inherently well-suited to them. The Casper is an excellent choice for side sleepers, as it outlines the natural curves of the body while delivering pressure relief for key areas. The zoned support of The Casper keeps the spine neutral and aligned, while the memory foam layer comfort layer provides contouring pressure relief at the hips and shoulders — reducing the pressure points that cause side sleepers to wake with discomfort. Casper sleep research consistently identifies side sleepers as the primary beneficiary of the medium-firm feel profile.
Back Sleepers
Back sleepers seek optimal spinal alignment, good edge support, and responsive lumbar support — and The Casper delivers on all three. With the right balance of zoned support, pressure relief, and medium firm feel, The Casper offers excellent comfort for back sleepers for a night of worry-free sleep. The Casper is characterised in our Casper mattress reviews as best for average-weight back sleepers who want a supportive mattress that cushions pressure points without sacrificing firmness. For back sleepers who prefer a bit firmer surface, The Casper Firm model provides firmer foam layers and stronger lumbar support throughout the night.
Stomach Sleepers
Although The Casper Medium has enough support to accommodate some stomach sleepers, it is not the ideal choice — the potential hip sinkage may cause discomfort and compromise spinal alignment for this sleeping position type. Stomach sleepers are best served by The Casper Firm or the Casper Original Hybrid Firm mattress, both of which use firmer foam layers and stronger support layer construction to keep the hips properly aligned during stomach sleepers-specific sleeping positions.
Combination Sleepers
Combination sleepers who change sleeping positions frequently will find The Casper comfortable and responsive across all positions. The foam composition provides balanced zoned support for stomach sleepers, back sleepers, and side sleepers alike — with pressure relief and support that adapts quickly as sleeping positions change throughout the night. The medium firm feel ensures the mattress transitions smoothly with the sleeper rather than requiring repositioning effort.
Lightweight Sleepers
With strong motion isolation and responsive open cell foam construction, The Casper reduces sleep interruptions for lightweight sleepers. The mattress performance for lighter body types is particularly strong — the foam layers contour more precisely at lighter weight loads, delivering better-than-average pressure relief and zoned support for lightweight profiles.
Heavy People
The Casper provides great support for a range of sleepers. However, all foam mattress designs can be hyper-adaptive to heavier body types, potentially causing deeper sinkage than desired. For this reason, heavier individuals who love The Casper bed should consider a Casper hybrid mattress model — such as the Casper Original Hybrid — which adds foam layers of pocketed coils beneath the memory foam layer for extra support, better edge support, and reduced sinkage for heavier sleep styles.
Should You Buy The Casper?
Overall, if you’re a side sleeper, back sleeper, or combination sleeper, The Casper offers a comfortable, supportive mattress environment to rest your best. Our in-house sleep trial and performance tests confirmed this memory foam mattress walks the walk — with impressive mattress performance results across motion isolation, cooling features, edge support, and pressure relief. Casper also boasts over 2,000,000 happy sleepers, a testament to long-term customer satisfaction with the brand’s sleep products.
With great support from high-quality foam layers and construction, this mattress is bound to make your sleep journey enjoyable across all sleeping positions. For the mid-range price point, The Casper shines as the superior choice compared to similarly-priced mattresses in Canada — such as Douglas Summit, Puffy Cloud, Emma Hybrid, and Logan & Cove Frontier Mattress.
You can buy Casper mattresses at Casper.ca or at Sleep Country Canada and Sleep Country stores nationwide. Visit a Sleep Country location to experience The Casper in person before committing — a genuine advantage for shoppers who want to test sleep styles and foam feel before their sleep trial begins.
