Best King Size Mattresses in Canada

While most mattresses on the market come in a king size option, not all are made with the same features and benefits. Besides the size, it’s important to examine your own sleeping preferences, like temperature control, if you co-sleep, and what position you tend to sleep in when choosing a new mattress.

Our team of experts tested countless king mattresses when narrowing down our top recommendations. We chose mattresses that had excellent motion isolation, various firmness levels and pressure relief properties. We looked at the following features when choosing our favourite king size mattresses in Canada.

Mattress Construction

Hybrid and all-foam mattresses are the most common types of mattresses in Canada, and we looked at the best of both kinds when researching. Constructed differently, these mattresses offer unique benefits from one another.

Hybrid mattresses are designed with multiple layers of foam that sit on top of a pocket coil foundation. The layers of foam tend to be thinner, and often, the mattress offers a plush and quilted top. Due to the design, you typically cannot wash the cover of these mattresses, but they do offer excellent cooling and pressure relief.

All foam mattresses are made from thicker layers of foam that are stacked and fused together. These mattresses tend to cost less than hybrid options and often have a removable and machine-washable cover. The ease of care of all-foam mattresses is a huge selling point, as are the temperature control and motion isolation properties.

Sleeping Position

Most Canadians have a preferred sleeping position, and identifying that before making a new mattress purchase is key. Our experts tested mattresses that are best suited for all different types of sleepers according to firmness levels.

Back sleepers will usually gravitate towards a firmer mattress, usually at a 7 or higher on the firmness scale in order to be the most comfortable. Stomach sleepers usually need a softer surface and should look at a mattress with a plush pillow or Euro Top or one that ranks at a 6 or lower.

Side sleepers, or those who may co-sleep with someone who sleeps differently than them, will want to look for a mattress that is medium firm. Choosing a king mattress that is a 6.5 or so on the firmness scale is a great balance and won’t be too hard or too soft.

Pressure Relief

Aching joints and sore pressure points are a common occurrence, especially for side sleepers or those with chronic joint issues. We looked for mattresses offering top-of-the-line pressure relief when recommending the best king-size mattresses in Canada.

Mattresses with pressure relief properties will often have more adaptive and responsive foam layers that cradle and soothe joints. Cooling gel foam and latex layers do a great job of aiding in pressure relief and can be found in many of the mattresses on our list today.

Temperature Control

Those who sleep hot often have to deal with waking up hot, sweaty and overheated. Our experts know that a mattress with poor temperature control can lead to sleepless nights and discomfort. We looked for king size mattresses that offered superior cooling properties in order to get the best sleep possible.

For those who sleep slightly warm, choosing a king size mattress with minimal temperature control measures will be enough to stay comfortable. Canadians who sleep hot or live in warmer climates, though, will want to select a mattress with more cooling features in place. Good cooling mattresses will have icy cold covers and cooling gel foam layers in order to reduce high heat and moisture.

Eco-Friendly & Organic Materials

Eco-conscious Canadians will love that organic and environmentally friendly mattresses are becoming increasingly popular. While often more expensive, these mattresses are typically made from sustainable and natural materials.

Our experts looked for the best king size organic mattresses on the market and chose one with excellent construction. Made with organic cotton, natural wool and recycled materials, eco-friendly mattresses stand out as some of the best you can buy. While beneficial to the planet, an organic mattress is also a great option for those with allergies or sensitivities to chemicals and adhesives.

Motion Isolation

Those who co-sleep with restless partners or active pets may find themselves struggling to get a full night’s sleep due to their movements waking them up throughout the night. Our team of researchers looked for king size mattresses that helped to stop motion before it could be transferred and disruptive.

Couples will want to choose a king size mattress that has built-in motion isolation in order to get restful sleep. These mattresses usually have layers of transition foam that help to absorb motion. Many hybrid mattresses also offer additional motion isolation with their support bases, but some high-quality all-foam mattresses also offer this.

Edge Support

Edge support, a feature that is often overlooked when choosing a new mattress, is something highly worth considering if you sleep near or on the edge of the bed. A good edge support system prevents sinking and sagging that can occur over time due to repeated sitting and sleeping.

Our experts tested multiple beds over time in order to find ones with great edge support systems. Crafted from strong steel coils that surround the perimeter of the mattress, these support systems help the mattress keep its shape year after year, regardless of where you happen to sleep on the bed.

Sleep Trials

Choosing to buy a bed-in-a-box mattress online means losing the ability to test them out in person. A great sleep trial policy, however, can ensure that you can test the mattress out for yourself risk-free.

Our team made sure that all of the king-size mattresses we recommended came with excellent sleep trial policies. These sleep trials range from 100 to 365 nights and allow for a full refund if you are not happy with them.

Typically, you must own the mattress for 30 nights before starting a refund in order to fully test the mattress out. If you aren’t happy after that time period, contact customer service to have them arrange a time to come and pick up your mattress for donation or recycling. After pickup, they will issue a refund back to the original form of payment, which can take a couple of weeks. 

Warranty Policies

A good warranty will ensure that you have some coverage in case of any issues with your mattress down the road. Each mattress that our team chose as our top king mattress comes with a warranty upon purchase.

Mattress warranties typically range from 10 to 20 years and cover issues like manufacturing defects, zipper and fabric flaws and large indents. They won’t cover damage caused by the user, spills, stains or sagging due to being on an improper frame.

To make a warranty claim, you will need to be the original owner, register the product (if applicable) and keep the receipts and tags on the mattress.
