How to Choose a Mattress: A Buying Guide
Replacing a mattress can feel like a lot to handle: websites, stores, foam versus springs, and figuring out how much to spend. This guide makes choosing a mattress simpler by walking through where to shop, the main mattress types, the best feel for your sleep position, and when it is time to replace your mattress. For our ranked Canadian picks, see the Best Mattress in Canada guide.
To choose a mattress, start with how you sleep: side sleepers want pressure relief and a medium-firm feel, back sleepers want medium-to-medium-firm support, and stomach sleepers want a firmer surface. Then pick a type: innerspring for bounce and cooling, foam for contouring, or a hybrid that combines coils and foam for the best of both. Buy where you can test it risk-free, and replace a mattress roughly every five to ten years.
Where to shop for a mattress
Lying down in a store is no longer the only option. Mattress-in-a-box brands have won over many buyers with convenient shipping and home trials. Here is how the two routes compare.
Shop in a store if
Choose the traditional route if you want a wider variety to try in person and the option to have your old mattress hauled away. The downsides are that a showroom can feel overwhelming, and it is harder to compare prices to know whether you are getting a fair deal. If you do test in store, do not rush. Lie down for at least ten minutes in your normal sleep position and check for any pressure or pain. And in a store, shop the sales rather than paying the sticker price.
Shop online if
Buying online suits people who would rather skip the showroom. There is often better value, since online brands do not carry showroom costs, and the mattress arrives boxed at your door within days. The biggest advantage is the home trial: you can sleep on it for up to 100 nights, with free shipping and returns, so the real test happens in your own bedroom. Hamuq, for example, ships free with a 120-night trial.
How to choose your mattress type
There are three common constructions: innerspring, foam, and hybrid, as well as adjustable air beds. There is no single right material, though foam and hybrids have surged in popularity online. Here is how to choose based on what matters to you.
If you like a bed with bounce
Innerspring mattresses give that familiar springy feel. Individually pocketed coils, each wrapped in fabric, reduce the ripple effect when a partner moves, so you get support and cooler airflow with less motion transfer than with older connected-coil designs.
If you prefer a contouring feel
Memory foam and latex mattresses have no springs, which can create a contouring or sinking feel with less lift under heavier areas of the body. Judge quality by foam density and thickness. Better online foam beds layer denser foam at the base for support and lighter, cooler foam on top for comfort.
If you want a plush top
Innerspring mattresses often add a fiberfill or foam top under quilted ticking. Do not be swayed by a thick pillowtop, since it can compress over time. Look for at least 2lb density in regular polyurethane foam and at least 4lb in memory foam. Anything lower tends not to last. A firmer, well-quilted mattress plus a replaceable topper is another route.
If you like to change the firmness
Consider an adjustable air bed with two side-by-side chambers, so each partner can set their own firmness. There are also flippable foam mattresses with a soft and a firm side, as well as modular designs that let you rearrange the internal springs.
If you sleep on your side
You want a surface that supports your weight while conforming to your shape. Pocket coils offer more pressure relief than most foam beds, though a soft foam mattress or one with zoned pressure relief at the shoulders and hips also works. Medium firm is usually the sweet spot. More in our side sleeper guide.
If you sleep on your stomach
An enveloping memory foam can feel smothering for stomach sleepers. A firmer surface provides better support, so consider a firm foam, a dense innerspring, or an adjustable air bed. More in our stomach sleeper guide.
If you sleep on your back
You want something firm but not too firm: a surface that supports while giving a little, so the spine stays in healthy alignment. Most types can work; test to see what feels best. More in our back sleeper guide.
If your partner tosses and turns
Look for pocketed coils, foam, latex, or a dual-chamber air bed. Medium-firm picks tend to have good motion isolation. Keep in mind that very soft all-foam beds can feel less comfortable for a restless sleeper, since there is little pushback against movement.
If you and your partner disagree on feel
A dual-chamber air bed lets each side be set separately, and some online brands let each partner customise a side through a questionnaire. A medium-firm hybrid is also a strong compromise that suits most sleep styles.
If you sleep hot
Cooling claims can get overstated once you add protectors, toppers, and sheets. Soft foam and latex can trap body heat, especially when you sink in deeply. Innerspring and hybrid mattresses tend to sleep cooler because the coil layer allows air to circulate, and cooling toppers and sheets help further.
If you have allergies
Latex and coils are naturally resistant to dust mites and mould. Whatever type you choose, an antimicrobial, hypoallergenic cover is a smart addition.
If you have back pain
Memory foam, latex, and innerspring can each work or fall short. A combination of zoned support, coils, and some foam usually gives the best balance of support and pressure relief. See our Best Mattress for Back Pain guide for details.
If you are concerned about chemicals
Look for foams certified by CertiPUR-US and for natural materials, such as certifications like the Global Organic Latex Standard (GOLS) for latex and Oeko-Tex for fabrics. To go deeper, see our guide to organic mattress certifications.
How and when to replace your mattress
Always check the return policy. A store may offer a partial refund, while online brands often arrange a local charity pickup and a full refund. Make sure you can test a new mattress for at least a month, risk-free, so you can adjust before deciding.
Read the warranty fine print, because a long warranty does not promise a set lifespan. Staining the mattress (use a protector) or skipping a proper foundation can void it. As a rule, mattresses last five to ten years, but let the warning signs decide: waking up sore, a lumpy surface, or sleeping better elsewhere, like in a hotel, all suggest it is time. Extend the life of a new mattress with a protector that keeps out dust, allergens, and spills.
If you cannot decide what matters most
A hybrid mattress combines the buoyancy and cooling of an innerspring core with the contouring and motion isolation of foam. It is a best-of-both-worlds option that suits many sleep styles and settles many partner disagreements, which is exactly the idea behind the Hamuq Original Hybrid.
The Hamuq Original Hybrid pairs 1,200-plus pocket coils with comfort foam for support, cooling, and motion isolation. Made in Canada, free shipping, 120-night trial.
Frequently Asked Questions
Start with your sleep position and any issues like back pain or sleeping hot, then choose a type that fits. Side sleepers want medium-firm pressure relief, back sleepers want medium-to-medium-firm support, and stomach sleepers want a firmer surface. Buy where you can test it risk-free.
Stores let you try more models in person, while online brands offer better value and a long home trial. The trial is the real test, since you judge the mattress in your own bedroom over weeks rather than minutes in a showroom.
The main types are innerspring (bouncy, cool), foam (contouring), and hybrid (coils plus foam), as well as adjustable air beds. A hybrid combines coil support and cooling with foam comfort and motion isolation.
As a general rule, every five to ten years. Let the warning signs guide you: waking up sore, a lumpy or sagging surface, or sleeping better away from home all suggest it is time to replace it.
A hybrid combines an innerspring coil core with layers of foam. It blends the support, bounce, and cooling of coils with the contouring and motion isolation of foam, which is why it suits a wide range of sleepers.
