Best King-Size Mattress Canada: Our Top Picks (2026)

A standard king-size mattress measures 76″ wide by 80″ long. This is generally enough room to fit two adults, as well as any kids or pets who want to pile into the bed.

If you and your partner have different sleep needs, you can try a split king instead. This type of bed is actually two twin XL mattresses, each measuring 38″ wide by 80″ long. A split king lets you combine different types of mattresses while still sleeping beside your partner. You can even use a split adjustable bed to fully customize your sleep experience.

If you’re over 6 feet tall, consider another variation on the king-size mattress: the California king. This mattress measures 72″ wide by 84″ long, meaning it’s four inches longer and four inches narrower than a standard king. It’s ideal if you have a taller body, or if you need extra room at the foot of the bed for your pets.

Mattresses fall into many different categories. Each has different characteristics that are a good fit for a variety of sleep styles. Here are just a few types of mattresses:

• Hybrid: Hybrid mattresses like Logan & Cove combine innerspring layers with foam or latex for a perfect pairing of contour and support. They tend to have better edge support and lower temperatures than memory foam, but this comes with reduced motion isolation for a slightly less peaceful sleep. (Shopping for a hybrid?

• Cooling Gel Foam: Some sleepers find normal memory foam too hot, so cooling gel foam mattresses like Douglas can be a great alternative. This type of mattress combines memory foam with cooling gel to keep temperatures comfortable while you sleep.
• Innerspring: Innerspring mattresses support your weight with metal coils. This makes the mattress bouncy and provides good edge support, but you might find this type of mattress less comfortable if your body needs more contouring.
• Memory Foam: Memory foam mattresses like Octave “hug” your body to relieve pressure and keep your spine aligned. They often incorporate zoned support, which can help relieve sore joints and provide other health benefits. In fact, the brand states that 86% of customers suffering from back pain said Octave helped reduce their pain.
• Latex: Natural or synthetic latex mattresses can relieve pressure in any sleep position. They have a reputation for comfortable temperatures and can last longer than other types of mattresses. However, latex mattresses can also be more expensive and may not be ideal for some people with latex allergies.

When you’re choosing a mattress, it’s important to consider more than just how comfortable it is. There is a whole range of factors to keep in mind, which we list below. (And when you’re ready to buy, make sure you buy a mattress online vs. in store.)

• Budget: Set a budget for your new mattress and stick to it. You might even be able to make this budget go further by finding limited-time deals and promotions online.
• Construction: Figure out what type of mattress you want, whether it’s foam, hybrid, or innerspring. There are pros and cons for each construction style, and knowing what you want will help narrow down your options.
• Firmness: Choose a mattress with the right firmness level for your sleep style—that is, whether you sleep on your side, back, or stomach. For example, side sleepers often want a softer mattress, while back sleepers may prefer something firmer. (Did you know that a medium-firm feel is ideal for most sleep styles?

• Pressure-Point Relief: Got achy joints? How about a sore back? If you do, look for a mattress with enhanced pressure-point relief so you sleep better at night. Octave Vista comes with five body-contouring support zones to aid in your body’s natural recovery and help you wake up pain-free the next day.
• Motion Isolation: Pay close attention to motion isolation if you share your bed with a partner, kids, or pets. The higher the isolation score, the less you’ll notice movement from the other side of the bed.
• Edge Support: Are you in the habit of sitting or sleeping near the edge of the bed? Look for a mattress with good edge support so you feel supported in any position.
• Bounce: If you have trouble getting out of bed in the morning, you might prefer a mattress with extra bounce. (Your inner child will enjoy it, too!)
• Contouring: Contouring materials like memory foam help support your body in all the right places. That said, too much “hug” can cause overheating and make it hard to move, so find the level of contouring that’s best for your body.
• Temperature: Speaking of overheating—if you’re a warm sleeper, look for a mattress that promotes airflow and reduces heat. Look for a mattress with cooling gel foam and other cooling technologies.
• Responsiveness: A responsive mattress allows you to change positions without feeling stuck. Often found in hybrid designs, a responsive mattress can help you enjoy certain activities in bed even more.
• Noise: Nobody likes a squeaky or crinkly mattress. Get a quiet night’s sleep with a mattress made from noise-quieting materials like foam or latex.
• Company Policies: Get details about the manufacturer’s sleep trial, return policy, and product warranty so you know what you’re getting into.
