Memory foam was designed by NASA to provide accurate pressure relief and superb durability in the seat cushions of rocket ships. The same traits make memory foam an ideal material for mattresses. This brings us to the question – how long do memory foam mattresses last?
Thanks to its superior quality, most of these beds come with a long warranty period ranging from five years to a lifetime. But, can it truly withstand wear and tear for 10 years or even a lifetime? How long does a Tempurpedic mattress last considering its generous warranty?
This article explores the average lifespan of a memory foam mattress and the signs to look out for if your bed is in need of a replacement despite its warranty. So, is it time for you to get a new mattress? Let’s find out!
Does Memory Foam Wear Out?
How can a tough foam that is crafted for rocket ships deteriorate? We all have heard the saying ‘nothing lasts forever’. Well, memory foam is no exception, as well as other mattress types. Though known for its robustness and longevity, a memory foam mattress also weakens and breaks down over time.
A memory foam bed made of higher quality materials and with above-average foam density should withstand your body weight and pressure longer than those with less expensive composition. However, both will eventually warrant replacement. Keep this in mind when shopping for a new mattress and remember that a more expensive option will most likely last longer.
How Often Should You Replace a Memory Foam Mattress?
It’s pretty obvious when an innerspring mattress has reached the end of its useful life because the coils start to squeak and poke uncomfortably. However, it may not always be so apparent with a memory foam mattress. So, how long do memory foam mattresses last?
As a general rule of thumb, your bed’s warranty should serve as an initial indicator of its durability. However, the lifespan of a memory foam mattress would also depend on two other important factors: support and cleanliness.
Does this type of mattress sag? Absolutely, and this condition implies that you’ll have to look for a new bed soon. When a mattress sags, it signifies that the foam density has degenerated and the bed has lost its bounciness. Hence, your body will leave visible hollows on the surface. Consequently, the compromised structure will most likely cause you discomfort by forcing your spine into an unnatural position. Additionally, if your sleeping companion is a bit heavier than you are, your body will roll onto their side while asleep, further straining your spine. Most mattress warranties will cover a replacement if a noticeable dip greater than three inches appears within the allotted time frame.
Aside from taking measurements, waking up with body pain or becoming increasingly restless during the night is another indication of a defective mattress. Also, if the top comfort layer of your mattress develops lumps or a noticeable change in firmness, it may indicate a significant deterioration.
For a mattress to last a bit longer, cleanliness is likewise essential. Not only to improve overall health but also to prevent the growth of bacteria that will eventually cause damage to your foam. Sweat, dirt, and dead skin cells naturally accumulate within the layers of your mattress which often encourage dust mites and mold. That’s why we recommend replacing your old bed every 8-10 years, even if it boasts a lifetime warranty.
Large spills or smudges caused by pets or children can be cleaned. However, if it happens quite frequently, the foam density can be compromised. One way to make a foam mattress last much longer is to use a bed cover or mattress protector to keep it clean.
Is It Time for a Replacement?
So, how long do memory foam mattresses last? Usually, they remain in useful condition for 8 to 10 years. However, if the bed develops any kind of pungent smell or deep indentations, you may want to replace it a bit sooner than 10 years.
Is memory foam the best mattress? When it comes to mattress foam, it is one of the most fantastic and highly durable. Still, choosing the best is ultimately up to your personal preferences. For most, particularly those with back problems, a memory foam mattress brings a better night’s sleep. If it’s time for you to get a new bed, we recommend one that incorporates this type of foam into its structure. Waking up feeling refreshed every day is definitely worth the investment.
