Mattress Breakdown

If you’ve shopped for an all-foam mattress in Canada, you might’ve come across Novaform, Casper, and Douglas. Each is a 3-layer foam mattress with good performance in edge support and motion isolation categories, and some cooling features. However, some of them perform better than others in certain areas.

The Novaform ComfortGrande Plus Advanced mattress is American-made and only available through Costco. It comes in just two sizes—queen and king—with prices starting at $699. Although it comes with a longer-than-industry-average 20-year warranty, it doesn’t include a sleep trial.

The Casper mattress is the most expensive option in this mattress comparison, starting at $999 for a twin size. It’s sold by Casper Canada and Sleep Country Canada. The model we received was made in Canada, but according to a Casper agent, their mattresses can be made in Canada or Vietnam. Casper mattresses come with a 100-night sleep trial and 10-year warranty, both industry-averages, but return and refund policies depend on where you purchase.

Finally, the Douglas Original mattress is designed and made in Canada by a Canadian company. Prices start at $599, and you can find the mattress online or in-store at GoodMorning retail locations. Douglas mattresses, which are available in a full range of sizes, including RV, come with a 365-night sleep trial, 15-year warranty, and a free bedding bundle with your purchase that includes a cotton sheet set, duvet cover, down alternative duvet, pillow(s), pillow protector(s), and a mattress protector.

Mattress Performance Results

 

Firmness

When tested by third-party engineers (commissioned by us), both Douglas Original and The Casper fell into our medium-firm category—the same as each one advertises. The Douglas mattress had a firmness score of 6.7/10, while The Casper earned a 6.0/10. Medium-firm mattresses tend to work well for side, back, and stomach sleepers alike.

In comparison, the Costco Novaform mattress earned a firmness score of 5.3/10. This slightly softer rating places it in our medium category. This mattress will likely still work for back and side sleepers, or lighterweight sleepers, but others may find they crave a little more support.

Edge Support

Strong edge support isn’t typically what foam mattresses are known for. However, all 3 mattresses in this review performed well in this area.

Novaform earned the lowest edge support score of the bunch with a 7.3/10. Douglas outperformed the Novaform with a very good 7.8/10 edge support score. Finally, The Casper earned an excellent edge support score of 8.5/10. Any of these mattresses should help you feel supported when sitting or sleeping near the edge of your bed.

 

Motion Isolation

Motion isolation refers to a mattress’s ability to reduce motion transfer from one side of the bed to the other. It can be an important factor to consider for couples when mattress shopping, or anyone sharing a bed with a child or pet. When comparing the Casper mattress vs Novaform, both earned very good motion isolation scores of 7.9 and 7.5/10, respectively.

But only the Douglas mattress earned an excellent score of 8.3/10 when it came to motion isolation. This could make Douglas Original a good choice if you share a bed, especially if you’re a light sleeper.

 

Bounce

Bounce in a mattress is a matter of personal preference, and we don’t factor it into our overall mattress ratings. Some sleepers will prefer the responsive feel of a spring mattress, while others enjoy the cushioning hug that foam mattresses often provide.

Douglas, Novaform, and Casper all earned below-average bounce scores, which aligns with their all-foam constructions. The Casper’s bounce score of 2.5/10 was the lowest, followed by the Novaform mattress at 2.9/10. Douglas Original’s score was slightly higher at 3.1/10, likely thanks to its responsive Elastex® foam, which should give you a little extra spring out of bed in the morning.

 

Cooling Features

Each of these 3 mattresses incorporates cooling features to help regulate temperatures throughout the night. Our mattress reviewers awarded The Casper a cooling feature score of 2.8/10 thanks to its open-cell perforated comfort layer. This should help promote some airflow throughout the mattress at night, but it might not be enough for sleepers who run warm.

The Novaform mattress also incorporates several cooling features. Its top cover is cool-to-the-touch, and it includes gel-infused foam, phase-change material, and a convoluted transition layer. These features will draw heat away from the sleeper and circulate air, which is why this mattress was awarded a 5.7/10 cooling feature score.

Douglas Original has similar cooling features to Novaform. With its CoolSense® cover, layer of ecoLight® cooling gel foam, and layer of breathable Elastex® foam, Douglas earned a 5.0/10 cooling feature score to help sleepers stay cooler at night.

Mattress Construction

Novaform ComfortGrande Plus Advanced, The Casper, and Douglas Original are all foam mattresses built with 3 layers. Each brand’s mattress is made using CertiPUR-US®-certified foams. Novaform is the tallest, at 14″, while Douglas and Casper both stand 10″ tall.

Douglas Original is designed and made in Canada by Douglas, a Canadian GoodMorning brand. Casper Canada is owned by Sleep Country Canada, but their mattresses can either be made in Vietnam or Canada, according to a Casper agent. Novaform is an American company that manufactures its mattresses in the United States. In Canada, Costco is likely the only place you’ll find Novaform mattresses.

 

Douglas Original Mattress Layers

• Layer 1: The 2″ top layer of the Douglas mattress is made of ecoLight® cooling gel foam. It’s just as durable, comfortable, and body-contouring as memory foam. This layer also has open-cell construction for extra breathability.
• Layer 2: The 2″ middle layer is made of Elastex® foam, which is latex free, for extra responsiveness and support.
• Layer 3: The 6″ bottom layer is made of motion isolation support foam. This helps dampen movements from the other side of the bed and is one reason why all Douglas mattresses have excellent motion isolation.

The Douglas mattress cover features a 360-degree zipper, making it easy to remove for machine washing. It’s made of spandex, polyester, and plant-based Infinitex® fibres that help keep you cool and dry throughout the night.

 

Novaform ComfortGrande Plus Advanced Layers

• Layer 1: The top (comfort) layer is 3″ of EVENcor GelPlus™ foam, which is designed to keep you cool and conforms to the shape of your body as you sleep.
• Layer 2: The middle (transition) layer is 3″ of premium support foam, designed with air channels to facilitate the dissipation of heat and odors.
• Layer 3: The bottom (support) layer is 8″ of support foam. This large, dense foam layer provides the mattress with the most stability and support.

Novaform’s cover is quilted with polyester for a bit of extra cushioning. The cover isn’t designed to be removed, so you’ll need to spot-clean any spills or stains with a damp cloth. It’s made of polyester, nylon, polyethylene, and spandex, and it has a cool-to-the-touch feel. Costco’s product page also describes the cover as being infused with antimicrobial protection, although it doesn’t explain what gives it this property.

 

The Casper Mattress Layers

• Layer 1: The top layer includes 1″ of Casper Signature Foam with AirScape® technology. This layer’s open-cell structure and perforations help promote airflow.
• Layer 2: The middle layer is 1.5″ of memory foam. This layer contours to your body, and helps prevent you from feeling the denser support layer beneath.
• Layer 3: The bottom layer is 6.5″ of dense ProSupport polyurethane support foam. This gives the mattress most of its structure and support, and stops you from sinking too deeply when lying down.

The Casper has a cover made from a blend of polyester, recycled polyester, cotton, recycled cotton, viscose, spandex, and polypropylene. It’s not removable or machine-washable. The company instead recommends spot-cleaning the mattress with water and a mild detergent as needed.

Delivery, Sleep Trial & Returns

Douglas

Douglas mattresses are available from the brand’s website or from its parent company’s retail locations. The company will ship to most locations in Canada for free (remote addresses may have an extra fee) in 2–10 business days. Douglas Original comes compressed in a convenient box with handles, making setup in your room of choice easier.

Your Douglas mattress comes with a 365-night sleep trial, one of the longest in the mattress industry, giving you up to a full year to try out the mattress. If you find that it works for your needs and decide to keep it, it’ll be backed by Douglas’s 15-year warranty. But if you decide to return it during your sleep trial, Douglas will arrange to pick up the mattress from your home for free. They will either donate it to a local charity or responsibly recycle it, and you’ll receive a full refund.

 

Novaform

This Novaform foam mattress is a Costco exclusive, so you’ll only find it on the retailer’s website or in select Costco warehouses. A membership is also required to make a purchase.

In-store Costco purchases need to be taken home yourself, and online purchases will ship to you for free in 3–10 business days. You won’t get a dedicated sleep trial with Novaform ComfortGrande Plus Advanced. But this mattress is eligible for return under Costco’s satisfaction-guaranteed policy, provided the store associates approve it. Online orders qualify for a mattress pick-up from your home, but if you purchased in-store, you’ll need to bring it back to the warehouse yourself, fully expanded.

If you decide to keep the Novaform mattress, it’ll be backed by Novaform’s 20-year manufacturer’s warranty.

 

Casper

If you buy The Casper mattress through the brand’s website, it should ship for free to your door in 5–15 business days. Additional fees may apply for more remote delivery locations.

Casper comes with a 100-night sleep trial, giving you roughly 3 months to decide if it’s the right fit for you. This is average for the industry. The mattress will be backed by a 10-year warranty if you decide to keep it. You can return the mattress during the trial period for a full refund, and Casper will pick it up from your home.

It’s important to note that these policies will be different if you purchase from Sleep Country, Casper Canada’s parent company. The sleep trial and warranty length will be the same. But the trial only qualifies you for a one-time exchange, which costs an extra $99. Be sure to read your retailer’s policies carefully before purchasing.
