Consistently good sleep is a cornerstone of health, and what you sleep on night after night can contribute towards the quality of your sleep. Buying the best mattress online for your preferred sleep position is one way to boost the overall quality and enjoyment of your slumber, but how long does the average mattress last? And how often should you change your mattress?
Well, there are different factors that come into play when answering this question. The type of mattress you buy, including what it’s made from, will have an impact on how long it lasts, as is the case with the best pillows. To muddy the waters further, different mattress brands make different claims about the average lifespan of a mattress.
Generally speaking, most standard mattresses have a lifespan of around seven to eight years. Allergens such as dust mites and bed bugs, and a build-up of bodily fluids (think sweat) and bacteria can also lead to a shorter shelf life. Speaking of sweat, if you tend to overheat during sleep, take a look at our guide to the best cooling mattress.
However, there are definite outliers in the world of mattresses, with some designed to last up to 20 years - these tend to be premium mattresses made of highly durable and allergen-resistant materials. Even the best bed toppers only last a few years by comparison, but they are a good solution if you aren't quite ready for a new mattress. Though if you are ready to buy a mattress and want the latest discounts, our best Purple mattress deals guide and our best Casper mattress deals round-up each have some fantastic offers.
As a rough indicator, these are the average lifespans for different types of mattresses:
- Innerspring: 5-10 years
- Hybrid mattress: 8-10 years
- Memory foam: 8-15 years
- Waterbed: 5-10 years
- Latex: varies, up to 20 years
It’s safe to assume that if your current mattress is showing obvious signs of wear and tear, and is uncomfortable when you lie on it, then it needs to be replaced. If your mattress is still comfortable and properly supportive of your body, but it’s covered in surface stains, you could help it last a little longer by learning how to clean your mattress properly.
Does your age factor into how often should you change your mattress?
According to the Better Sleep Council, the average mattress should be replaced every seven years. Apart from how the mattress might degrade over time, this timeframe is also suggested because our bodies change as we get older and our sleep needs change too. So the perfect mattress for us seven years ago may feel a lot different now. The truth is, each of us needs more in-bed support and comfort as we get older, so it makes sense that our mattress requirements also evolve.
Again, there are exceptions to this rule and you may find that your current mattress is still up to the job, or that you have purchased a mattress designed to last far longer than the average lifespan. If not, and you have a feeling that your mattress just isn’t up to par any more, there are 5 signs that you need to replace your mattress.
Different mattress brands and average lifespan
If you can find them, read the care guidelines for your existing mattress as they may state an average or expected lifespan based on proper care, cleaning and use - that means positioning the mattress on a proper bed base and not leaving it on the floor. As mentioned above, different mattress brands state different average lifespans for their mattresses, so let’s look at some of the more popular brands now…
These are designed to last for 10-20 years, according to Purple, and comes with a 10-year full replacement cost warranty.

How to protect your mattress
- 1. Check the manufacturers label for care advice before cleaning.
- 2. Buy a mattress protector and wash it every two months to reduce bacteria and other allergens.
- 3. Unless the manufacturer states otherwise, most mattresses should be flipped every 3-6 months to help them maintain shape and to wear more evenly.
