Pros
-
Accessibly priced at $699 for a queen size - 20-year limited warranty is longer than the industry average
- Costco has a generous return policy with full refunds and pickup for online orders
- Very good edge support and motion isolation scores
Cons
-
Cover is not machine-washable (spot clean only) - Doesn’t come with a sleep trial
- No zoned support for spinal alignment or pressure relief
- Sold exclusively through Costco, meaning you’ll need a membership to buy
Product Overview
The Novaform ComfortGrande Plus Advanced is a 3-layer, 14″ tall gel memory foam mattress made in the USA. It comes with a decent number of cooling features to help keep temperatures comfortable throughout the night. Plus, in third-party engineer testing that was commissioned by us, Novaform earned very good scores for both motion isolation and edge support.
At $699 for a queen-size, Novaform is priced lower than some other competitor foam mattresses. It comes with a 20-year limited warranty and can be returned through Costco’s standard return policy, which includes pickup and a full refund. All that said, the mattress doesn’t come with a dedicated sleep trial, and you’ll need a Costco membership to buy it. Costco will pick up returned mattresses purchased online, but not ones bought in-store.
If you’re weighing your options, the Douglas Original is a strong alternative. The Canadian-made Douglas also features gel memory foam and a cooling cover, but earned better edge support and motion isolation scores than Novaform. It comes with a longer 365-night sleep trial, a free bedding bundle, and free return pickup right from your house, all for a competitive price of $799 for a queen size. You don’t need a membership to buy a Douglas, either.

Novaform Mattress Construction
The Novaform ComfortGrande Plus Advanced is a combination foam mattress with a medium feel. It stands 14" tall and is built with 3 distinct foam layers. Novaform performed well in edge support and motion isolation tests, and has below-average bounce.
In Canada, this model is only available for purchase in queen and king sizes, priced at $699 and $899, respectively. It's also sold exclusively through Costco, so you'll need a membership to buy one.
Mattress Layers
The Novaform ComfortGrande Plus Advanced is built with 3 layers of foam. Like many memory foam mattresses, each layer has its own properties and works with the others to create an overall sense of support and comfort.
- 1st Layer: 3" of EVENcor GelPlus™ memory foam designed to relieve pressure and wick away heat for a cooler sleep surface.
- 2nd Layer: 3" of transition foam adds support between the soft comfort layer and the firm base, helping reduce motion transfer and improve stability.
- 3rd Layer: 8" of high-density base foam provides support and durability to the overall mattress structure.
Mattress Cover
The Novaform mattress has a quilted, textured white cover with a soft feel and a subtle wave pattern. Its navy blue sidewalls and matching accents give it a clean, modern look. The cover isn't removable or machine-washable, so you'll need to spot-clean it if there's a spill. It's infused with antimicrobial protection and feels cool to the touch. There are sturdy handles on the sidewalls that make it easier to move the mattress around.
Mattress Testing
To ensure our mattress reviews are thorough and trustworthy, we buy the products ourselves and have them tested by independent licensed engineers (commissioned by us) with no stake in the results.
These third-party engineers apply a consistent testing process to every mattress using a detailed framework. Every mattress is tested the same way, whether it's foam or hybrid. Because these types perform differently, we rate them on separate scales to ensure the scores are fair and meaningful.
We believe independent testing is essential to producing reliable and meaningful comparisons. That's why all test results are reviewed and signed off by an APEGA-certified engineer, operating under a strict code of ethics.
We use the testing results and over 40 criteria to build our scoring methodology.
Tests and reviews without this level of professional oversight may be more prone to errors and unintended bias.
Delivery & Other Policies
When you order the Novaform ComfortGrande Plus Advanced from Costco Canada, it'll arrive compressed in a box and shipped directly to your home. Delivery typically takes between 3–10 business days, and shipping is free. The mattress is an online-only option from Costco, so you won't find it in person at a warehouse.
Costco offers a generous return policy that lets you return the mattress at any time for a full refund, so long as it's in decent condition. If the mattress isn't the right fit, you can contact Costco to schedule a free pickup; no need to re-box the mattress or bring it to a store. However, you'll need a Costco membership to make the purchase or initiate a return.
The mattress includes a 20-year limited warranty that covers defects in materials and workmanship, such as excessive sagging or foam breakdown.

Frequently Asked Questions
Is Costco recalling the Novaform mattress?
Yes. In 2023, FXI Inc., the maker of Novaform mattresses, voluntarily recalled approximately 48,000 ComfortGrande and Serafina mattresses sold at Costco due to the potential presence of mould. This issue was linked to how the mattresses were stored in their packaging before sale. The recall impacted a limited batch, and there have been no follow-up recalls since.
If you'd prefer to buy from a company with stronger customer satisfaction, Douglas Original might be a better fit. Its parent company, GoodMorning.com, is rated "A+" on the BBB with a 4.9/5 customer review score. Douglas itself is rated "Excellent" on Trustpilot based on hundreds of verified reviews.

All the content on our site, from product reviews to comparisons, is intended to provide general information to help guide your mattress search. We work with independent third-party engineers to test all mattress products we purchase, and we use the test results alongside public data to inform our reviews and comparisons.
The product details in each review reflect how the mattress performed at the time we purchased and tested it, as shown by the "Published" date.
Since brands can update their materials, pricing, or availability over time, we also note when the product was originally purchased, either directly in the article or on our disclaimer page, to maintain clarity and transparency.
If you see an "Updated" tag on a page with a more recent date than the published date, it simply means we've made editorial changes. It does not necessarily indicate any update to the mattress or its test data.
Finally, unless otherwise stated, any mention of where a mattress is made refers specifically to the product we received and tested.
