How Often Should You Replace Your Mattress?

A good night’s sleep is important to our physical and mental health. One of the best ways to get better sleep is by having a good mattress. But how often should you replace your mattress and what happens when you hold onto it for too long? We spoke to a cleaning expert to learn more, including tips on how to make the mattress you already have last longer.

How Often You Should Change Your Mattress

It’s recommended to change your mattress every 7 to 10 years, according to Rechelle Balanzat, cleaning expert and CEO of JULIETTE in New York City. One major factor to consider is that “mattresses can lose their ability to provide comfort and support over time which can lead to poor sleep quality, back pain, and other discomforts,” Balanzat explains. “A new mattress ensures optimal support for your body, promoting better sleep and overall health.”

An old mattress can also impact your hygiene. “Mattresses accumulate dust mites, dead skin cells, sweat, and other bodily fluids over the years,” says Balanzat. “This can lead to an unhealthy sleeping environment, contributing to allergies, asthma, and other respiratory issues.”

Changing your mattress also ensures a flat and comfortable surface while you sleep without any uncomfortable lumps. Balanzat adds that new mattresses offer improved technology. “Mattress technology and materials continually evolve, with new designs offering better support, comfort, and durability,” she says. “Upgrading to a newer mattress can provide benefits not available in older models.”

Signs You Need to Change Your Mattress

Balanzat says any visible sagging or indentations in the mattress can be major signs it’s time to be replaced. “If your mattress has noticeable dips, lumps, or sags, it can no longer provide proper support,” she says. “This can lead to discomfort and poor sleep posture.”

Another key sign to watch out for is any unpleasant smells coming from your mattress. “Over time, mattresses can absorb odors from sweat, spills, and other sources,” says Balanzat. If your mattress is stinky or your allergies or asthma have worsened, it’s time for a replacement.

Lastly, check your mattress for any noticeable wear and tear. “Any visible damage such as tears, holes, or fraying fabric are signs that your mattress has reached the end of its lifespan,” says Balanzat.

Tips on Helping Your Mattress Last Longer

• Use a mattress encasement. Balanzat says a full mattress encasement will help increase the longevity of your mattress. “Invest in a high-quality, zippered mattress encasement that fully encloses your mattress,” she says. “This will protect it from dust mites, bed bugs, spills, and stains.”
• Use a mattress protector. It’s also a good idea to add a waterproof mattress protector on top of the encasement which helps add “an extra layer of defense against spills and accidents, making it easier to keep your mattress clean,” Balanzat says. The mattress protector and encasement should be cleaned regularly following the manufacturer’s instructions for proper care and washing.
• Invest in good sheets. Balanzat explains that high-quality, breathable sheets are also ideal and should be changed often to help reduce the transfer of body oils, sweat, and dirt to the mattress cover.
• Get a sturdy bed frame. A supportive bed frame will prevent sagging and structural damage.
• Rotate and flip your mattress regularly. Remember to rotate your mattress every three to six months and if it is double-sided Balanzat states it’s important to flip it as well to ensure even wear.
• Adjust the humidity. Your bedroom environment can also impact your mattress. This means if you live in humid climates, use a dehumidifier. Balanzat explains this will help “prevent moisture buildup and reduce the risk of mold and mildew.”
