Mattress Breakdown

Comparing the Novaform foam mattress to Douglas, a few things stand out. Douglas has a medium-firm feel that provides balanced support and pressure-point relief. Medium-firm mattresses are commonly thought to work for most sleepers, so Douglas should be comfortable whether you sleep on your side, stomach, or back. Douglas Original also provides comfortable cooling so that you can sleep comfortably throughout the night, with features like a CoolSense® cover, open-cell foam, and cooling gel foam.

The Douglas mattress earned higher scores than the Novaform mattress for edge support and motion isolation in third-party engineer testing (commissioned by us). It also comes with a machine-washable cover for convenient cleaning, and a sleep trial, both of which you won’t get with the Costco Novaform mattress.

In comparison, while the American-made Novaform ComfortGrande Plus Advanced has a slightly lower price tag, it doesn’t offer as much as Douglas. Novaform is only available in 2 sizes: queen and king. Its medium feel may not offer enough support for certain sleeping positions. In addition, Novaform mattresses from Costco won’t come with a sleep trial, so you’ll have to rely on Costco’s return policy. You also need a Costco membership to buy this mattress, since it’s only available online.

In this Douglas vs Novaform mattress review, we’ve gathered all the information you need to accurately compare these two mattresses.

Mattress Performance Results

 

Firmness

In third-party engineer testing (commissioned by us), the Douglas Original tested as a medium-firm mattress with a firmness score of 6.7/10, which is suitable for all sleep styles. It provides a balance between support and body-contouring comfort pressure relief.

Novaform ComfortGrande Plus Advanced, on the other hand, had a slightly softer medium feel, with a score of 5.3/10. While medium mattresses can be good for side and back sleepers, as well as lightweight individuals, stomach or heavier sleepers might prefer a firmer mattress.

Edge Support

Good edge support is important if you like sitting or lounging on the side of your mattress, sleeping closer to the edge, or having extra stability when getting in and out of bed. In testing, Douglas Original earned a very good edge support score of 7.8/10.

While Novaform ComfortGrande Plus Advanced also performed well with a score of 7.3/10, if you want the mattress with better overall edge support, you might prefer Douglas.

 

Motion Isolation

Novaform ComfortGrande Plus Advanced scored 7.5/10 for motion isolation, which is a very good score for a foam mattress. You shouldn’t notice most of your partner’s movements when they change sleep positions.

In comparison, Douglas Original scored even higher for motion isolation at 8.3/10. This is an excellent score for a foam mattress, which could make Douglas the stronger choice for anyone sharing their bed with a partner or pet.

 

Bounce

Bounce is a matter of personal preference. It measures how quickly a mattress bounces back to its original shape after pressure is applied. Foam mattresses typically have lower bounce compared to mattresses with springy coils.

Both the Douglas Original mattress and the Novaform ComfortGrande Plus Advanced received below-average bounce scores. The Novaform mattress earned a 2.9/10 for bounce, while the Douglas Original received a slightly higher score of 3.1/10.

 

Cooling Features

Many modern foam mattresses incorporate at least a few cooling features to help keep temperatures comfortable at night, and the Novaform and Douglas mattresses are no exception. Douglas earned a cooling feature score of 5.0/10, thanks to features like a cooling cover infused with Infinitex® fibres, open-cell foam for breathability, and cooling gel foam that helps regulate temperature.

Novaform ComfortGrande Plus Advanced also has a few noteworthy features to help you sleep cool at night. It has a cover that’s cool to the touch, gel memory foam infused with phase-change material, and air channels that allow airflow throughout the mattress. These elements earned Novaform a cooling features score of 5.7/10. Either mattress will help you sleep cool at night.

Mattress Construction

Both Douglas and Novaform are 3-layer foam mattresses. Each uses CertiPUR-US® certified foams. While Douglas is made in Canada by a Canadian brand, Novaform is made in the U.S by an American manufacturer.

 

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 Original mattress comes with the brand’s signature CoolSense® cover, which can be removed and machine-washed for simple cleaning. The cover is made of a blend of polyester and spandex, along with plant-based Infinitex™ fibres that help draw moisture away for a fresher, drier sleep surface.

 

Novaform ComfortGrande Plus Advanced Mattress Layers

• Layer 1: The top (comfort) layer is 3″ of EVENcor GelPlus™ memory foam with phase-change material, which is designed to keep you cool and contour around the shape of your body as you sleep.
• Layer 2: The middle (transition) layer is 3″ of support foam, designed with air channels to help dissipate heat and maintain airflow.
• Layer 3: The bottom (support) layer is 8″ of support foam. This high-density foam layer provides the mattress with stability and support.

Novaform ComfortGrande Plus Advanced features a cool-to-the-touch quilted top cover treated with antimicrobial protection. This cover isn’t removable or machine-washable, so you will need to spot-clean spills or stains. The mattress’s law label suggests using a damp cloth.

Delivery, Sleep Trial & Returns

 

Douglas

Douglas mattresses ship by ground for free to most Canadian locations using FedEx. For remote locations, some additional fees might apply. Your order ships from Ontario or Alberta and will make it to your door in 2–10 business days, including dispatch and delivery time. The mattress arrives compressed, sealed in plastic, and packed in a box, making it convenient to move to your bedroom.

Douglas offers a 365-night sleep trial to test the mattress at home. If you choose to return your mattress, Douglas will pick it up for free during the sleep trial period and issue you a full refund. Returned mattresses are either donated to a local charity or recycled, depending on what’s available in your area. If you keep your Douglas, it’s backed by a 15-year warranty, which is longer than average for the mattress industry.

 

Novaform

Novaform ComfortGrande Plus Advanced is exclusive to Costco, so you’ll need a Costco membership to purchase it. Costco will ship this mattress to online customers for free via UPS and provide white-glove delivery, including mattress placement, setup, and packaging removal. Dispatch and delivery will take 3–10 business days, and the mattress will arrive on your doorstep wrapped in plastic and rolled up in a box.

Novaform mattresses sold through Costco come with a 20-year warranty, but no sleep trial. That means there’s no guaranteed period for you to make sure the mattress fits your needs. However, you may be able to return it through Costco’s satisfaction-guaranteed policy. Shoppers who bought the mattress in person will have to bring it back to the store themselves, while online shoppers can contact Costco to schedule a return pickup—just keep in mind it can take several weeks to arrange.
