Testing Mattress Toppers in Canada

How We Test Mattress Toppers for Canadians

We test all of our Mattress toppers using the same mattresses. This helps us determine what benefits we are getting from the mattress topper and which are from the mattress itself. We test for feel, cooling, and additional support. 

Additionally, we look at the composition of the mattress topper, its available sizes, and a host of other features that help us determine how it will work for you.

Our Selection Process for Mattress Toppers in Canada

We select mattress toppers that perform well across multiple categories. We look at how our testers felt about the topper and compare their feedback to our testing data. Once we have both sets of data, we can recommend the options that we felt stood out to us.

Our goal is to make sure that we recommend options that will work well for most Canadians. That’s how you know you’re getting only the best options we could find.

• Materials: 9/10
• Waterproofing: 9/10
• Size Options: 10/10
• Feel: 9/10
• Fit: 9/10

Highlights

• Hypoallergenic materials

“This Mattress topper has kept my mattress looking great for months. Even though I sweat a lot, there’s no visible staining on my mattress.”

— Slumber.ca Verified Mattress Topper Review (Silk & Snow Mattress Topper)

Materials

This mattress topper is made with polyester and polyethylene. The polyester creates a smooth, comfortable top that is soft to the touch. The polyethylene layer helps add waterproofing without being too crinkly. This layer creates a barrier for liquids, dust, allergens, and dirt. The polyester also helps wick away moisture, so liquids like sweat won’t pool on top of this waterproof barrier. 

This Mattress topper is 100% machine washable at home. There are some additional care instructions, but it isn’t difficult to wash. 

Waterproofing

The Silk & Snow Mattress topper is fully waterproof. It uses moisture-wicking materials to keep stains off your mattress, especially when it comes to sweat stains. The waterproofing works by wicking moisture away from the source rather than allowing liquids to pool on the surface. This also makes it easier to clean spills and accidents without creating a bigger mess.

Performance

The Silk & Snow Mattress topper performs well in most of the categories we tested. While it won’t add any additional comfort to your mattress, it also doesn’t hinder the mattress’s ability to keep you cool or offer support. In fact, this cover can help you sleep cooler overall, since it has cooling properties for those who sleep hot. It doesn’t hold on to excess heat, moving it away and wicking away moisture to reduce sweating. 

Size and Other Options

The Silk & Snow Mattress topper comes in six standard mattress sizes. These include Twin, Twin XL, Full, Queen, King, and California King. We recommend checking the dimensions of this protector against the dimensions of your mattresses. While these sizes are standardized most of the time, it’s best to make sure that the Mattress topper will fit.

Who is the Silk & Snow Mattress Topper For?

• Those with allergies. This Mattress topper works to protect against liquid spills and dust, but it also blocks out allergens.
• Canadians who sleep warm. If you usually wake up hot at night, this Mattress topper can help keep you cool by wicking away moisture and reducing heat.
• Users who want a lengthy sleep trial. The Silk & Snow Mattress Topper has a 100-night sleep trial, so you can try it before you discover if it works for you.

Who Should Avoid the Silk & Snow Mattress Topper?

• Those who want to change the feel of their mattress. This topper works perfectly for its intended purpose, but it doesn’t add any support or comfort to the top of the mattress.

Alternative Option

If you want a mattress topper that will change the feel of your mattress as well as offer protection, consider checking out the Silk & Snow Organic Mattress Topper or the Casper Comfy Mattress Topper. These use layers of foam to create additional comfort and support, rather than just adding a layer of protection.

Best Organic – Silk & Snow Organic Mattress Topper

Best Organic
The Silk & Snow Organic Mattress Topper uses organic latex and organic cotton to create its unique, comforting feel.

• Materials: 10/10
• Waterproofing: 5/10
• Size Options: 10/10
• Feel: 9.5/10
• Fit: 9/10

Highlights

• Fully organic materials
• Two firmness options to adjust how your mattress feels
• 100-night sleep trial to try it out

“The mattress topper felt great. We chose the Firm version to keep our mattress more supportive, and it worked a treat.”

— Slumber.ca Verified Mattress Topper Review (Silk & Snow Organic Mattress Topper)

Materials

The Silk & Snow Organic Mattress Topper includes a topper and a cover. The topper is made with 100% Global Organic Latex Standard (GOLS) certified Dunlop latex. This is a natural latex that isn’t created with chemicals. It comes from a family-owned latex manufacturer located in Sri Lanka, because Silk & Snow is dedicated to providing the highest possible materials. 

The cover for the topper is made with 100% GOTS (Global Organic Textile Standard) certified cotton. This is a fully organic cotton that feels smooth to the touch. It’s grown sustainably and meets strict organic certification standards. 

Waterproofing

This topper isn’t waterproof. The cover and the topper are made with materials that can easily be soaked in the event of a spill. While the cover can protect the topper and your mattress from dirt and wear, you may need to use a waterproof mattress protector if you want to prevent sweat staining and spills from affecting your mattress.

Performance

Aside from waterproofing, this mattress topper performed extremely well for our testers. The dense foam has two different firmness options, which can help change how your mattress feels. The Medium option makes your mattress softer and relieves pressure, while the Firm version keeps your mattress supportive. There is a price difference between them because of the density of the materials. The Firm version costs more.

Otherwise, most of our testers said they liked how this topper felt and how well it worked to reduce strain. It significantly changed the feel of their mattresses, leading to more comfortable sleep when installed correctly. In most cases, it also helped testers sleep cooler than their mattress alone.

Size and Other Options

The Silk & Snow Organic Mattress Topper is available in two firmness options, including a Medium and a Firm option for those looking to change the comfort or support level of their mattress. It’s available in six standard mattress sizes with dimensions that match standard sizing. 

Here are the available sizes and their dimensions, so you can figure out which will fit best on your existing mattress.

• Twin: 75″ x 38″ x 2″
• Twin XL: 80″ x 38″ x 2″
• Full: 75″ x 54″ x 2″
• Queen: 80″ x 60″ x 2″
• King: 80″ x 76″ x 2″
• California King: 84″ x 72″ x 2″

The topper itself is 2″ deep, so it will add this much to your mattress depth. Keep this in mind for your sheets, as some sheets can only fit mattresses up to a certain depth.

Who is the Silk & Snow Organic Mattress Topper For?

• Canadians who want to change the feel of their mattresses. The two firmness options (Firm and Medium) allow you to change how your mattress feels for better support or pressure relief.
• Those who sleep warm. Cool latex and breathable cotton mean this mattress topper sleeps a little cooler than others.
• Eco-conscious Canadians. This mattress topper is made with eco-conscious, sustainable materials that give you a little more peace of mind.

Who Should Avoid the Silk & Snow Organic Mattress Topper?

• Canadians who want a waterproof protector. This mattress topper is comfortable, but you may need a mattress protector as well for waterproofing.

Alternative Option

If you want a mattress topper that offers more waterproof properties, you may want to choose the Silk & Snow Mattress Protector instead. Of course, using both together is a much better option. This way, you’ll get the waterproof properties of the mattress protector with the comfortable boost offered by the mattress topper.

Best Memory Foam – Casper Comfy Mattress Topper

Best Memory Foam
This memory foam mattress topper makes your mattress more comfortable through three inches of premium, perforated foams.

• Materials: 10/10
• Waterproofing: 6/10
• Size Options: 10/10
• Feel: 9.5/10
• Fit: 8/10

Highlights

• Protects against sweat and light moisture
• A full 3″ thick for pressure relief
• Easy care cover can be washed at home.

“This topper is thick and comfortable. I can’t believe how much it changed how our mattress felt.”

— Slumber.ca Verified Mattress Topper Review (Casper Comfy Mattress Topper)

Materials

The Casper Comfy Topper uses two foam layers inside a comfortable knit cover. The two foam layers include a top layer of responsive foam and a bottom layer of memory foam. Both are aerated, with hundreds of tiny holes to increase airflow. This helps with breathability and increases the topper’s cooling properties. 

The cozy knit cover is made with a blend of materials. It’s 86% polyester, 10% cotton, 2% rayon, and 2% spandex. This allows it to stretch perfectly over the foam insert without having too much extra fabric.

Waterproofing

Whiel this mattress topper isn’t waterproof, it does have some light protection against moisture. The cover is breathable and protects the foam (and your mattress) against stains from sweat or light moisture, though it won’t hold up to larger spills.

Performance

The Casper Comfy Mattress Topper is one of the thickest mattress toppers on our list. At 3″ tall, it uses a 1.5″ layer of responsive polyfoam, followed by a 1.5″ layer of pressure-relieving memory foam. The result is a topper that helps you sleep more comfortably, whether you move around a lot at night or need better relief for pressure points. 

Our testers loved this extra thickness. They said it really changed the way their mattress felt, adding much-needed comfort, breathability, and leaving them with fewer pressure points overall. It was particularly useful on older, broken-down mattresses. 

Size and Other Options

The Casper Comfy Mattress Topper comes in all six standard mattress sizes. This includes Twin, Twin XL, Full, Queen, King, and California King. Because this topper doens’t attach to your mattress in the normal ways, it’s important to keep the dimensions of the topper in mind. It is made to work with all Casper mattresses. If you don’t own a Casper mattress, here’s how the size breaks down:

• Twin: 74″ x 37.5″ x 3″
• Twin XL: 79.5″ x 37.5″ x 3″
• Full: 74.5″ x 52.5″ x 3″
• Queen: 79.5″ x 59.5″ x 3″
• King: 79.5″ x 75.5″ x 3″
• California King: 83.5″ x 71.5″ x 3″ 

Who is the Casper Comfy Mattress Topper For?

• Hot sleepers. This mattress uses aerated foams (including memory foam) to create better breathability throughout. This leads to much better cooling properties.
• Canadians who need pressure relief. This 3″ topper offers extreme pressure relief, particularly for side sleepers or those looking to add softness to their mattress. 
• Those who prioritize easy care. It’s easy to zip off the cover of this topper and throw it in the washing machine when it needs to be cleaned.

Who Should Avoid the Casper Comfy Mattress Topper?

• Those who want to choose their topper’s firmness. If you want to choose how a topper makes your mattress feel, this might not be the topper for you. It has a single firmness option.

Alternative Option

This is a thicker foam topper meant to change the feel of your mattress. If you want choices in how a topper will make your mattress feel, look into the Silk & Snow Organic Mattress Topper. If you want a waterproof protector that doesn’t affect how your mattress performs at all, consider the Silk & Snow Mattress Protector.

Comparing the Best Mattress Toppers in Canada

FAQs

How many inches of a mattress topper is best? 

A mattress topper that is meant to change how your mattress feels should be at least 2″ thick. Thicker mattress protectors can be better for those who want a softer mattress, or those who sleep on their sides.

How do I pick the right mattress topper?

First, you have to determine how your mattress feels. If your mattress is too soft, a firmer mattress topper can help increase support and reduce sinking. However, a mattress that is too firm may benefit from a plush mattress topper. Determine what you need from a mattress protector before you get started.

How thick should a mattress topper be for a side sleeper?

We recommend a mattress topper that is at least 3″ thick for side sleepers. This provides the additional pressure relief necessary to keep side sleepers comfortable and well-aligned.

Which is the most comfortable mattress topper?

The Casper Comfy Mattress Topper is the most comfortable mattress topper on our list. This option is 3″ thick and uses layers of aerated polyfoam and memory foam to create extra contouring and relief for uncomfortable pressure points. 

Do mattress toppers protect against dirt and spills?

A mattress topper will protect your mattress against dirt, as they create an additional barrier between your mattress and your body. However, they may not be waterproof. Some have waterproof properties, but if you need to keep your mattress and your topper dry and clean, we recommend pairing the mattress topper with a mattress protector.

Can you use a fitted sheet over a mattress topper?

Yes, you should use a fitted sheet over your mattress topper. This keeps it in place and prevents too much movement. Make sure to choose sheets that have deep enough pockets to cover both the mattress topper and your mattress.
