After sleeping on the same mattress since 2008, Vancouverite Lindsay Nieminen had enough of the lumps. Comfort was her top priority, and she was willing to pay for it.
“It was time for an upgrade. Since switching, I’ve noticed I wake up without feeling sore in my back and hips. It was absolutely worth the $2,000 price tag,” she says.
It’s a familiar problem. But in a market saturated with sleep claims, coil counts and cooling covers, knowing what actually warrants that kind of investment is harder than it sounds. Walk into any mattress showroom or website, and you’re met with a barrage of claims. Pressure relief, spinal alignment, copper-infused foam, cooling gel covers, coil counts — the promises and claims stack up quickly. Some of it is real, but a lot of it is noise.
“Coil counts and cooling covers are showroom language,” says Jack Dell’Accio, founder of Canadian brand Essentia Organic Mattress. “If it doesn’t improve your sleep architecture, it’s marketing.”
What actually affects sleep quality, as supported by research, is how well a mattress redistributes pressure and whether its materials allow your body to regulate temperature through the night.
Essentia Organic Mattress founder Jack Dell’Accio warns against being overresponsive to marketing tactics, when it comes to buying a mattress.
“Proper spinal alignment prevents stiffness, pressure relief reduces discomfort and tossing, and breathability helps you stay cool and in deeper sleep. Everything should support those fundamentals.
If it doesn’t improve comfort, it’s often just noise,” says Van Kutrowski, manager of Retail & Product Experience at Endy.
Pressure pinpoints
Mattresses that reduce pressure points, such as shoulders and hips, and keep the spine in neutral alignment are linked to less joint and muscle pain, fewer nighttime awakenings and improved perceived sleep quality.
A 2008 study in the Journal of Chiropractic Medicine found that participants who replaced their mattresses (average age: 9.5 years), reported a 55.3 per cent improvement in sleep quality and a 48.9 per cent reduction in back pain.
A 2015 systematic review in Sleep Science confirmed that mattress design directly influences sleep comfort, pain levels and spinal alignment. While most research suggests medium-firm mattresses suit the widest range of sleepers, optimal firmness ultimately depends on each individual’s body type, sleep position and pain points.
Taking temperature
Humans sleep best when our core body temperature drops slightly at night. Sleeping too hot can disrupt that process.
Research published in Physiology and Behavior found that a mattress drawing heat away from the body measurably increased slow-wave sleep, the deepest, most restorative stage, compared to a conventional mattress. Overly warm mattresses don’t just feel uncomfortable. They reduce the time your brain spends in the sleep stages that restore physical and cognitive function.
How a mattress handles heat depends on its materials. Traditional memory foam mattresses tend to trap heat because they contour closely to the body and limit airflow, though newer designs aim to reduce this. Innerspring and hybrid mattresses often sleep cooler, thanks to air circulating through their coil layers. Natural latex, with its more open structure, is generally less heat-retentive than memory foam, while materials like wool can wick moisture and help regulate surface temperature.
When is it time to upgrade your mattress?
You probably already know if your mattress is working against your sleep. But at what point does an upgrade make a measurable difference?
Watch for signs like waking up tired after a full night, persistent morning stiffness or sleeping noticeably better in a hotel or guest bed — though these symptoms can also point to menopause or sleep apnea. If you’ve ruled those out, or your mattress is more than eight to 10 years old, it may be time for a replacement. Many manufacturers offer generous return and exchange policies.
“At that point, a mattress change is not a comfort upgrade,” says Dell’Accio. “It’s a performance decision, the same way an athlete would evaluate anything else in their recovery that’s producing poor results.”
