Which Is Better: Novaform, Casper, or Douglas?

Novaform and Casper are well-known foam mattress brands available in Canada. But while these mattresses are popular, they both lack some features that are available in other competitor mattresses, like machine-washable covers. It’s also important to know that their sleep trial and warranty lengths are only industry average. If you’re comparing Casper vs Novaform while shopping for a foam mattress, we recommend also checking out Douglas.

Only Douglas offers multiple cooling features, excellent motion isolation, a 365-night sleep trial, a 20-year warranty, and a free bedding bundle with your purchase—all at an affordable price of $799 for a queen size.

Overall Ratings

Edge support and motion isolation are factored into our overall mattress ratings. These scores are shown in green (scores of 5.0+), yellow (3.0–4.9), or red (2.9 and below). Firmness, bounce, and cooling features are a matter of personal preference and aren’t part of our rating system, so these scores are shown in grey.

Mattress Breakdown

Novaform ComfortGrande Plus is sold through Costco in Canada and requires a paid membership to purchase. While this memory foam mattress has good motion isolation and a 20-year warranty, it doesn’t come with a sleep trial when purchased through Costco. It is, however, subject to Costco’s return policy. It was also included in a 2023 product recall.

The Casper is also a memory foam mattress and has some basic cooling features to balance out potential heat trapping. It lacks the zoned support found in Casper Original, the mattress’s previous version, despite being sold at the same price point. The Casper has good motion isolation and edge support but only comes with an industry-standard 100-night sleep trial and 10-year warranty. Casper has occasional sales that may get you a free accessory with your purchase.

Douglas outperforms both Novaform and Casper with top scores in edge support and motion isolation, the highest number of cooling features, and a machine-washable cover. It also has a much longer 365-night sleep trial and a generous 20-year warranty. Each Douglas comes with a free sheet set, pillow(s), mattress protector, and pillow protector(s), so you’re sleep-ready right after receiving your mattress.

To help you choose between Casper vs Novaform vs Douglas, we’ve gathered all the information you need to accurately compare these mattresses.

Note: This page features a previous version of The Casper mattress, and a discontinued version of the Novaform mattress. Newer models may vary in construction and performance.

Mattress Performance Results

Firmness

Douglas Original, Novaform ComfortGrande Plus, and The Casper are all foam mattresses with a medium-firm feel. That level of firmness is ideal whether you sleep on your side, stomach, or back, so any of these mattresses should suit a wide variety of sleepers.

Edge Support

Foam mattresses generally don’t have good edge support. Douglas Original, however, has an edge support score of 7.8/10, which is a very good score for an all-foam mattress. With Douglas, you can sit or lie closer to the edge of the bed comfortably.

In comparison, The Casper scored slightly lower, but similarly well to Douglas with a score of 7.5/10 for edge support. Novaform ComfortGrande Plus scored lowest for edge support out of all three mattresses at 3.5/10—a very low score, even for a foam mattress. You may find it difficult to sit on the edge of the bed or lie farther away from the middle on Novaform.

Motion Isolation

Motion isolation is important for a good night’s sleep, especially if you’re a light sleeper. Douglas Original beats both of its competitors with an excellent motion isolation score of 8.3/10. The Casper scored lower at 6.6/10, and Novaform ComfortGrande Plus scored just 6.5/10. If your partner tosses and turns, or if you’re easily disturbed by nighttime movements, Douglas is the best choice for a restful sleep.

Bounce

Bounce is a matter of preference in a mattress. The Casper has a 4.7/10 bounce score, which is average for a foam mattress. Novaform ComfortGrande Plus has a much lower bounce score at 3.2/10. However, Douglas Original has the lowest bounce score of all three mattresses, coming in at 3.1/10—ideal if you’re a light sleeper or don’t enjoy a very responsive surface.

Cooling Features

Foam mattresses can be known to trap heat, so most modern foam mattresses incorporate cooling features to make sleep more comfortable. Novaform, Casper, and Douglas all feature cooling technologies in their construction—but not each mattress incorporates the same number of cooling features.

The Casper earned a cooling features score of 2.5/10 due to its perforated, open-cell foam comfort layer that promotes better airflow throughout the mattress. This is the only layer with cooling features in the mattress.

Novaform ComfortGrande Plus scored somewhat higher at 3.2/10, thanks to its moisture-wicking top cover, cooling gel foam layer, and air channels carved into its middle layer.

Douglas Original has the highest cooling features score of all three mattresses at 4.2/10. It earned this score due to its CoolSense® cover, layer of ecoLight® cooling gel foam, and layer of breathable Elastex® foam. If you’re looking for a quality foam mattress to keep temperatures balanced as you sleep, Douglas is your best choice.

Mattress Construction

Douglas Original, Novaform ComfortGrande Plus, and The Casper are all foam mattresses with 3 layers each. The Douglas and Casper mattresses are both 10″ tall, while Novaform is 14″ tall. While Douglas mattresses are Canadian-owned and made, Casper has only switched over production to Canada since its acquisition by Sleep Country Canada. The version of The Casper we purchased was still made in the United States. All Novaform mattresses are also produced in the US.

Douglas 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 for extra spring and support. This is a latex-free foam with a similar level of responsiveness and support.
• Layer 3: The 6″ bottom layer is made of motion isolation support foam. This means you’ll hardly feel a thing from the other side of the bed, even if your partner is tossing and turning all night long.

Douglas Original’s cover is removable and machine washable for easy care. Made using plant-based Infinitex™ fibres, this cover wicks moisture away and helps keep you cool and comfortable throughout the night.

Novaform Layers

• Layer 1: The top (comfort) layer is 3″ of EVENcor GelPlus™ foam, which Novaform claims will 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 ComfortGrande Plus has a quilted, moisture-wicking top cover. However, this cover is not removable or machine washable. All spills or stains should be spot-cleaned only. Novaform was also included in a recall order due to possible mould exposure.

Casper Mattress Layers

• Layer 1: The top (comfort) layer includes 1″ of polyurethane foam, which uses open-cell perforations to enhance airflow. Casper says this feature promotes comfort and regulates body temperature during sleep.
• Layer 2: The middle (transition) layer is 2″ of body-contouring memory foam. This supports your body and prevents long-term sagging in the middle of the mattress. Memory foam can be known to trap heat without added cooling features to increase airflow.
• Layer 3: The bottom (support) layer is 7″ of dense polyurethane support foam. This foundational component maintains the mattress’s structure and support, ensuring that you won’t sink too far into the upper layers.

The Casper’s top cover has a zipper, but according to Casper, it isn’t meant to be removed or machine-washed. Spills or stains should be spot-cleaned only.

Delivery, Sleep Trial & Returns

Douglas

Douglas ships its mattresses for free to most locations in Canada via FedEx. An additional fee applies if you’re ordering from a remote location. Your order will ship from Alberta or Ontario and arrive in 2–10 business days, including dispatch and delivery time.

Douglas ships in a convenient box and is wrapped in two sheets of heavy-duty plastic. Once it’s unrolled and fully expanded, it’s sleep-ready on the same day it arrives.

READ MORE: How to unbox a mattress

Douglas offers a 365-night sleep trial so you can test out the mattress at home. You can return the mattress at any point during the sleep trial. If you decide to return your mattress, returns come with free pickup service and a full refund. The company will then organize your mattress to be donated upon pickup. If you keep your mattress, it’ll be backed by Douglas’s generous 20-year warranty.

Novaform

Note: The Novaform ComfortGrande Plus mattress has been discontinued and replaced with a newer model. This newer model is still available for purchase through Costco. 

Novaform sells its ComfortGrande Plus mattress through Costco, which means you need a Costco membership to buy it. This mattress may be purchased either in-person or on the Costco website. You’ll also need to bring a truck if you decide to buy the mattress in-person, since Costco only offers shipping for online orders.

If you order this mattress online, Costco will use its in-house courier service to ship it to you in 10–15 business days, including dispatch and delivery time. Like Douglas, Novaform arrives boxed and is wrapped in heavy-duty plastic. According to the FAQ on Novaform’s website, it may take up to 48 hours for the mattress to expand to its full size, although they say you can sleep on it as soon as it looks comfortable.

While Novaform offers a 90-night sleep trial on its mattresses, you won’t get one when purchasing through Costco. You will however be subject to Costco’s open ended return policy. If you decide to return the mattress, Costco only provides return shipping for online purchases. Buying in-store means hauling it back to the store yourself. Novaform ComfortGrande Plus also comes with a generous 20-year warranty.

Casper

Casper offers free shipping to most locations in Canada and should arrive on your doorstep in 5–15 business days. This is the case for mattresses purchased online or from one of Casper’s brick-and-mortar Sleep Shop locations. However, additional fees apply if you’re ordering from a remote area. Mattresses sold through third-party retailers such as Sleep Country may be delivered using different couriers and with different delivery timelines. Different trial and return policies may also apply, like Sleep Country’s exchange-only policy.

The Casper will ship to you boxed and wrapped in two layers of plastic. It should be ready to sleep on the same day it arrives.

Casper offers a 100-night sleep trial for its mattresses. You can return the mattress during the trial period, but only after the first 30 nights of the trial have passed—almost a full third of the total warranty period. Casper also ships with an industry-standard 10-year warranty.
