How often should you replace your mattress?

Under normal conditions, mattresses should be changed every 6 to 8 years. Of course, this is a general guideline and not a one-size-fits-all solution. There are several factors that influence when to replace the mattress. The average mattress lasts between six and 10 years, but many people can and do so for longer because of its cost.

The truth is, there's no single way to know how long each mattress will actually last. There are many factors that influence this fluctuating number of years, such as the type of mattress, the quality of its materials and the way it is cared for. Next, we explain how often you should replace your own mattress and how to ensure its longevity, as well as some ways to extend the life of your existing bed. Most mattresses with inner springs or with pocket springs need to be changed every four to six years.

There are higher quality options, such as Silentnight and Dreams, and they are guaranteed to last a little longer because they use better quality wire and construction methods. The Better Sleep Council (opens in new tab) recommends changing your mattress every seven years. You'll find slightly different advice from expert to expert, but most agree to let a period of between six and ten years go by, depending on how often the mattress is used and the quality level of the mattress. If you see or feel the springs going through the mattress cover, it's time to change it.

While widespread opinion (and the mattress manufacturing industry) say that a bed's mattress should be changed at least every eight to ten years, the decision isn't that simple. There are simply no strict guidelines on when a mattress should be replaced, as there are many variables that contribute to the wear and tear of a mattress. However, an uneven mattress will cause aches and pains, and it's a clear sign that it's time to change it. Over time, the mattress will begin to naturally adapt to your body weight and your sleeping position, but large valleys, crevices, grooves or saggy areas that prevent you from achieving proper spinal alignment are a sign that you should replace the mattress.
