Some things you want to last forever—that first bite of a chocolate chip cookie or a hug from a good friend after a long, difficult day.
One thing we definitely wish could last forever? The comfort of a memory foam mattress. But like all good things, the lifetime of a memory foam mattress is not infinite. So how long do memory foam mattresses last? While most mattresses last only around seven years, the mattress lifespan of memory foam material can last for 10.1
But many factors can affect a memory foam’s mattress longevity and, most importantly, your sleep health.
How to Ensure Longevity for a Memory Foam Mattress
When answering “how long do memory foam mattresses last?” we have to consider the care element. Think of your memory foam mattress like a sleek new car with all the bells and whistles. If you take it for regular tune-ups and keep it clean, you’ll get plenty of mileage out of your vehicle. But if you treat the “Maintenance Required” lights on the dashboard as a suggestion, you might be parting ways sooner than the manufacturer intended.
The same goes for a mattress. How you treat your mattress can ensure you enjoy many long, dreamy years together. In which case, consider:
- Rotating it – Rotating your mattress helps distribute your weight evenly across the mattress’ surface. This can help prevent a sagging mattress or avert lumps from forming. Not sure how often to rotate a mattress? Every two or six months, rotate your mattress 180 degrees so your head will be where your feet used to be. Then, in another few months, rotate it again.
- Using a mattress protector – As soon as you buy a new mattress, buy a quality mattress protector to keep it company. Your mattress protector safeguards your new mattress from stains, dirt, dust mites, and bacteria that could impact its lifespan. To that end, our Waterproof Mattress Protector does a phenomenal job of keeping your mattress safe from stains, spills, and dirt while keeping you safe from potential irritants. Plus, it’s machine washable, making it even easier to keep your memory foam bed clean.
- Washing your bedding regularly – A mattress is only as clean as the bedding you use. By regularly washing your sheets, blankets, and mattress cover, you can help keep your mattress spring-time fresh even as it reaches the winter of its lifespan. Want some mattress cleaning tips?

- Using a strong frame – Your mattress supports your blissful journey to sleep. But what’s supporting it? A strong bed frame can help prevent sagging, lumps, and bumps in a mattress for the long term. Our bed frames come in a variety of shapes and styles, so you can find the perfect match for your memory foam mattress. Not sure which frame is right for you? Check out our guide to help you learn how to choose a bed frame for your needs!
- Airing it out – On bright, dry days, let your foam layer mattress breathe. Strip your bedding, turn on a ceiling fan if you have one, and give your mattress a few hours to air out. This will help prevent odor buildup as well as dry out any excess moisture that your mattress may have absorbed while asleep. Moisture can lead to mold and bacteria, so giving your mattress some time to air out will benefit both you and your mattress in the long run, and can contribute to greater mattress longevity.
Wondering, are memory foam mattresses hot and if that is a contributing factor to excess moisture in your mattress? The answer depends on the quality of your memory foam mattress.
What Affects the Lifespan of a Foam Mattress?
The lifespan of a mattress is heavily influenced by its materials, construction, and foam density. Simply put, not all types of mattresses are created equal—different brands use different materials, leading to varying durability. Casper prioritizes high-quality materials to produce longer-lasting mattresses. Here’s what affects how long yours will hold up:
1. Foam Quality: Not All Are Created Equal
High-quality memory foam mattresses with premium materials stand the test of time, while cheaper alternatives tend to break down faster.
At Casper, every layer of foam undergoes extensive in-house and third-party testing to ensure long-lasting comfort and support. From dry and wet heat compression set testing to ASTM F1566 rollator testing, our materials are put through the paces to simulate 10 years of consistent use—so you can rest easy knowing your mattress is built to last.

2. Your Body Weight & Sleep Style
Your body weight affects how a mattress wears over time. Heavier sleepers may experience a sagging mattress sooner, while lighter sleepers might get a few extra years. In contrast, lighter individuals may find their memory foam mattresses last longer. Likewise, side sleepers might see more wear in hip and shoulder areas.
3. Temperature & Humidity
Memory foam is sensitive to temperature. Excess heat and moisture can cause it to break down faster. A cool, well-ventilated bedroom can help extend its lifespan.
4. Care & Maintenance
Neglecting your mattress? Expect a shorter lifespan. A little TLC—rotating, cleaning, and using a mattress protector—goes a long way. Check out our blog for expert tips on mattress maintenance!
How to Tell When It’s Time for a New Memory Foam Mattress
As much as you may love your memory foam mattress (especially if you got it from us), sometimes, you need to look for the signs to know when it’s time to move on. Even a quality mattress can reach its age limit.
- Your mattress sags – If the surface of your mattress looks like it has an imprint of a sleeping snow angel, it’s definitely time to upgrade your old mattress as this is one of the most obvious signs you need a new mattress. When you can see dips or you-shaped pockets in your mattress, this means the mattress can no longer provide the support and pressure relief you need, which can result in neck, shoulder, hip, or back pain.
- Your mattress is more than ten years old – Age might be a state of mind for people, but for mattresses, it’s a solid way to determine whether it’s time to start browsing for a new bed. After ten years of wear and tear, absorbing sweat, oil, skin cells, dirt, and grime, and possibly a few jumping-on-the-bed-sessions, it’s time to let your old mattress retire.
- You’ve noticed you’re having allergy or asthma flare-ups – Memory foam mattresses, like every mattress type, can accumulate quite a bit of dust and dander over the years (even with the best of care). Unfortunately, this can directly impact your sleep health and you may wake up feeling sniffly or wheezy every morning. If that’s the case, your memory foam bed is ready to join the big bedroom in the sky.
