Knowing when to replace a mattress can be tricky — like most things that get used every day, changes develop gradually over time and may be difficult to notice. Often, it’s not until we try a new mattress that we realize how much better we could be sleeping.

As a general rule, most sources will advise replacing a mattress every ten years. However, advances in manufacturing technology mean some of today’s higher-end units can last 15 to 20 years, or longer — and are warrantied accordingly. Provided you take some basic steps to keep your mattress clean and well-maintained, the more you invest upfront, the more use you can expect to get out of your purchase.
So, how do you known when it’s time to replace your mattress? Here are some things to ask yourself:

• Am I still getting a good night’s sleep? Waking up sore or achy can be a sign your mattress is no longer delivering the comfort you require of it. Have you been finding yourself more tired and sluggish during the day or more prone to illness? Provided other causes have been ruled out, these symptoms indicate it may be time to replace your mattress.

• Have my sleep habits changed since I purchased my mattress? Gaining or losing significant amounts of weight, sharing the bed with a partner, and illness or persistent injury to the back or neck are all factors that can affect your sleep. Replacing your mattress to reflect these changes can help you sleep more soundly.

• Is my mattress still in good condition? If a mattress is sagging, shifting or creaking, it may warrant replacement. Physical signs of mattress wear include rips, stain and lumps, foul smells and more. When traditional coil mattresses age, their ability to support your body decreases — if you feel yourself sinking into your mattress, it’s time to replace it.
Mattresses should also be replaced following a bedbug infestation, or if allergies develop that make it difficult to sleep.

Making Your Mattress Last Longer

Whether you’ve just replaced your mattress or want to take steps to increase the life of an older one, there are a few things you can do:

• Rotate it regularly: This will distribute your weight more evenly and reduce the amount of pressure on certain areas.

• Keep it clean: Mattresses should be vacuumed and deodorized as part of regular maintenance. Don’t let stains sit for long.

• Invest in a good quality cover: A machine-washable mattress cover makes cleanup easy.
