How Long Do Mattresses Last? The Results May Shock You!

Mattresses are pretty expensive — one quick glance at our buyer’s guide will confirm this fact. This is why many people do not replace them – not even after many years of use.

They do not want to spend a lot of money on a new one. Besides, now you can delay the process of buying a new one if you do an excellent job at maintaining your existing one.So, how often should you replace your mattress?

It doesn’t matter which type of bed you have. Most of them are ready for replacement within ten years to ensure a good night’s rest (old mattresses can hurt your sleep quality). Besides, it can last beyond ten years on average, if the owners maintain it properly.

Also, many different factors affect a bed’s lifespan. You can extend its life expectancy by following a few easy steps in the text below. We prepared and wrote down some tips to boost its longevity.

Frequently Asked Questions

Click on a question below to view the response.

Can you give me the retail price on any Kingsdown mattress set?

Approved Kingsdown dealers set their own retail prices and some of them have pricing online. Please check our retailer locator for a store near you.

Can I sleep on the reverse side of a one-sided bed?

We do not recommend it because the surface on the underside of a one-sided mattress was not designed for sleeping. Sleeping on the underside of the mattress should not cause structural damage to the mattress but you may experience body impressions.

How much body impression should I expect on the surface of my mattress?

Body impressions up to 1.5” are considered normal and desirable in luxury mattresses. Our mattresses are designed to conform to your body over time while still delivering correct postural support.

To quote the Better Sleep Council on body impressions:“Many of today’s top-quality mattresses use extra-plush foams and fibers to create comfort layers designed to cradle your body and relieve pressure. In the first few weeks you sleep on a new mattress with extra comfort layers, you will likely notice some body impressions on the surface. These impressions are normal. They indicate that the comfort layers are conforming to your body as they are supposed to do, and shouldn’t be considered a sign that something is wrong with your new mattress.”

Please refer to your Mattress Care and Warranty booklet for any rotation instructions that may apply to your Kingsdown mattress.

I have had my bed a few months and I already have body impressions. Will the body impressions get worse over time?

Materials in your sleep system will settle most within the first weeks of ownership. You should expect some degree of body signature, but deeper impressions should not occur. If they do, please contact the dealer where you originally purchased your sleep system.

My bed has an odor. Where does this come from?

The foam that is used in the manufacturing process can produce off-gassing but this should dissipate within a week. This only occurs when the mattress comes straight through production and is sent directly to the customer. Kingsdown does not warehouse inventory, our beds are produced as they are ordered from our retail partners. We recommend airing the mattress out for a few days. If the odor persists, please contact the retailer where you originally purchased your sleep set.

How often should mattresses be replaced? How long do they last?

Mattresses wear out on different timetables due to numerous factors such as how the mattress is used (guest room, master bedroom, doubled as a trampoline for the kids, etc.), whether it’s cared for properly and the quality of the mattress itself. Another important consideration is how your personal comfort preferences or lifestyle and body might change over the years. We encourage you to assess your mattress after eight years and, depending on use, care, and your answers to the questions below, consider a replacement:

  • Are you sleeping better or worse than you did a year ago?
  • Are you waking up feeling stiff and sore?
  • Does your mattress have visible signs of wear and tear?
  • Would a new mattress improve your sleep?

The industry standard is to replace your sleep system every 8-10 years.

What is the best mattress that you manufacture?

When it comes to mattresses, there is no “one-size-fits-all” solution. We are all built differently and have different comfort preferences, so why would the same mattress be "best" for all of us? To determine the mattress that’s best for you, we recommend using our proprietary diagnostic system, bedMATCH™. All Kingsdown mattress are crafted with care by employee-owners, and tested for quality and accurate postural support before they leave our facility.

Do I need to buy a new box spring when I buy a new mattress?

We highly recommend purchasing a new box spring with your new Kingsdown mattress. Our mattresses and box springs are made to work together as a cohesive unit. When a new mattress is placed on an old box spring, the old box spring does not allow the mattress to perform to its design capabilities for pressure relief and postural support.

What type of warranty do you have on your product?

The specific model that you purchase determines your sleep system’s warranty. You may download warranty information here. For information on your warranty, please contact Consumer Relations at 1-800-800-1353, Tuesday-Friday from 10:00am-2:00pm EST.

How often should I rotate my mattress?

The recommendation is to rotate after the first month of ownership and then four times per year, as the seasons change. Rotating your mattress allows the cushioning and insulation materials to be evenly and properly distributed, providing maximum comfort and longevity. Not all Kingsdown sleep systems require rotation; please refer to your Mattress Care and Warranty booklet for further details.

Will my sheets fit? Where do I find sheets?

It’s important to remember your Kingsdown sleep system will require sheets that fit loosely. Tight fitting sheets can create a “drum” surface on your mattress. If your sheets are too tight, this can cause a “roll to the middle” effect. If you’re in the market for new bed linens, we recommend Dream World Design. They manufacture bed linens to fit all Kingsdown sleep systems. You can contact them at 1-800-955-1322 or visit their website.

It looks a lot taller/higher than the bed I have now. Will it fit my bed?

It’s always a good idea to measure where your new mattress will strike your headboard. However, all quality mattresses are thicker and plusher today to allow for pressure relief and a better night’s sleep. Studies have shown that pressure is the biggest sleep thief at night. If your mattress is cutting off proper circulation and creating pressure points, you will awaken with aches and pain from tossing and turning. Have you ever noticed that your arm was numb or that you hip was still asleep even after you awoke? That’s a good indication that your mattress isn’t supporting or conforming to you properly.

What can I do if the mattress is too high for my bed?

The last thing you want to give up is the comfort and support of your Kingsdown mattress. There are several possible solutions to making your new Kingsdown mattress work:

  • Use a low profile bed frame that is designed to lower your sleep system approximately 4”
  • Consider using an extra-low profile box spring
  • Talk with your sleep professional in the store and he or she may have other solutions they can suggest

Do your beds generate heat? What can I do to control the heat?

We have had some questions regarding heat. Different body chemistries react differently. Our sleep systems can generate some heat but this is due to the fact that our systems conform to your body and you tend to sleep longer in one position without adjustment, which is what you want. We suggest that you purchase a 100% cotton mattress pad or a thermally sensitive pad that will help wick away moisture. Using lighter weight bed linens is helpful as well.

Should I still use my big fluffy pillows?

The first thing you should consider after buying a new bed is purchasing new sleeping pillows. This is the most important accessory to your new sleep system, and the smaller the better! A queen or king size pillow, though it may look nice when the bed is made up, is too large of a pillow for most people to sleep with. A big fluffy pillow, in conjunction with your conforming sleep surface, can cause improper postural alignment. We recommend a pillow that supports your neck and head in a natural way, keeping your spine aligned. When you buy a new mattress, give yourself two to three weeks to allow the bed to start conforming to your body, and to allow your body to adjust to proper postural support.

It feels softer than what I have been sleeping on – should I be concerned? New sleep technology, combined with new foams and fibers, means you no longer have to suffer on a hard, uncomfortable mattress. Kingsdown mattresses support your body properly while also providing a comfortable sleep surface that relieves pressure points.

How Long Do Mattresses Last?

Mattresses aren’t exactly cheap, most people replace them very infrequently and consider buying a new one either a chore or a burden. It’s easy to delay or prolong this process simply by taking proper care of whichever type you own. As a general rule, most should be replaced within ten years for best results in sleep and health, however, the average life of a mattress can last beyond ten years or more if taken care of properly. While it is true that how long one lasts depends on different factors, you can easily increase its life expectancy by undertaking a small number of simple steps. Here is a look at a few of the factors that can decide how long should a mattress last, and possible ways to increase its lifespan:

Table of Contents

1. The Type

What type do you have? For instance, is it air, innerspring, memory foam or latex? Each one has its own life expectancy; air and innerspring being the shortest, memory foam being mid length, while latex types are known to last the longest.

  • Air mattresses will over time either develop leaks or generally become less effective at retaining air pressure. If they have a built-in pump that becomes faulty, this too can lead to premature replacement. Overall, the average air mattress life expectancy is placed at five years.
  • Spring mattresses are good for sharing couples who like a springy and bouncy surface, but unfortunately, due to the inner core being thin metal wire, this type does tend to sag and lose its support even if flipped and rotated regularly. Even ones which have been well cared for will most likely need replacing within 7-8 years.
  • Memory foam mattresses are less prone to sagging but not invincible. They too require rotating, and foam does eventually lose its support but after a long while. This type should be good for at least ten years if kept ventilated, clean, and rotated.
  • Latex mattresses are the creme de la creme and tick all the boxes for quality and longevity. The naturally hypoallergenic and anti-microbial properties add to the durable nature of latex rubber foam to combine a core which can last up to 15 years.

2. Regular Cleaning

Another important factor which determines mattress life expectancy is to do with cleaning.Howdo you clean it? Do you clean itregularly? Do you give it to aprofessionalcleaner? It’s essential that you clean your mattress regularly to prolong the life. If you do not, it won’t last long at all. This is due to the invisible bacteria, mildew, and mattress mold that can slowly eat away at the materials involved. Moreover, it may be better if you could have it cleaned professionally from time to time, as mattresses are home to bacteria and germs in plenty, which might not get adequately cleansed with household cleaning products and methods.

3. Amount of Use

As you can imagine, anything that is used more will last less. However, there are two things that need to be kept in mind. Whichever type you own, it wouldn’t last as long in cases of extreme use, for example sharing couples who use for 10+ hours per day, and secondly on the other hand, if it has been left unused and uncleaned for prolong periods of time. Mattresses that are moderately used, where people sleep on it for around 7-8 hours a day, and then cleaned regularly are the ones that have the longest life.

4. The Cleaning Products

The question of how long do mattresses last really is to do with many supporting factors, but quite often depends on the cleaning methods used to clean them. For instance, in case of blood stains, you might have to use hydrogen peroxide to get rid. Too much of this chemical (and other heavy duty stain removers) would lead to a reduction of mattress life as these are not made to withstand such chemical uses.

5. Proper Precautions

It is always nice to have kids around the house. However, if your kids want to use your bed as a trampoline, it seriously isn’t a good idea. You would rather have them play elsewhere since this can seriously damage your bed. Imagine you have an innerspring, the springs will become too soft and compressed in no time at all and will leave you with a creaky and sagging surface. Additionally, whether it’s latex or memory foam, soon there will be indentations which are beyond repair. To prolong its life, you can also rotate and flip it from time to time, but that’s only if it’s double-sided and permits you to do so. You could perform this every few months for the duration of its life, which will significantly improve how long a mattress can last.

When Do You Know You Cannot Use Your Mattress?

Usually, mattresses that are over seven years old do not provide the comfort and support you need on the bed. Once you see there are signs of the surface and support wearing out, or you’re feeling uncomfortable in the bed when you are sleeping on it, you would be better off changing it. Some of the common visible signs of wearing are sagging, holes and tearing. If you cannot get a full night’s sleep and feel that you’re having a better slumber elsewhere than your bed, you need to start looking for a replacement.

You might buy the most expensive mattress, but if you do not care for it properly, it might not even last ten years. On the other side, ones which are taken care of correctly are known to last more than 15 years.

How Long Should A Mattress Last?

Your mattress is one of the most hard-working items of furniture you’ll own.

Mattresses can seem expensive when considered as an upfront cost, but when you think about them as an investment, they start to make more sense.

Perhaps because we aren’t awake for most of the time we spend on our mattress, we don’t give it much consideration. But to state the obvious, we do spend roughly a third of our time lying down on one.

In fact, one of the defining characteristics of a good mattress is that it goes unnoticed. Being aware of where your body meets your mattress at night, is a sign that you might have picked the wrong one or it’s time to replace it.

Find out how long mattresses should last in this post and you’ll discover if your mattress is too old and decide whether it’s time to look for a new one.

How long does a mattress last?

General advice is that a mattress will last between 7 and 10 years before it starts to decline and becomes uncomfortable.

But knowing if your mattress is too old can be difficult to notice until it’s too late. If getting out of bed is painful and you’re waking up with new aches in your neck, shoulders, and back, it might be a sign that your mattress is no longer supporting you.

A mattresses lifespan is not only determined by the support it gives but whether it has become a haven for dust and allergens. If you find yourself sneezing in bed more than you do in other parts of your home, and your mattress is reaching the 10 year mark, it might be time for an update.

If you’re about to invest in a mattress and you’re sensitive to allergens such as dust, or just want to increase your new mattress’s lifespan, consider getting a custom made lambswool mattress or using a mattress protector which is easy to clean.

Different types of mattress have different expected lifespans, however, with futon and air mattresses typically lasting a much shorter amount of time, while deep filled, pocket sprung mattresses tend to last longer.

Factors in mattress longevity

Aside from the type of mattress you choose, there are a range of other factors that go into determining how long your mattress will last.

How much do you use your mattress?

The more you sleep on a mattress, the more you’ll compress the springs or cushioning. Over time this will decrease the supportiveness of the bed and start to cause issues with comfort and quality of sleep.

A mattress that is slept on every night will understandably age a lot more quickly than one that’s not, so it’s likely that your spare room mattress will last much longer than the one in your bedroom.

Spend time maintaining your mattress

Apart from protecting your mattress from liquids and allergens with a mattress protector, and cleaning your mattress, flipping it every season will allow it to wear evenly. It will also give each side of your mattress time to recover between seasons, meaning you’ll get more use out of it.

You should look to flip your mattress over every 3-6 months, but you can also rotate it 180° (so that the bottom is now the top) more regularly to give it even more longevity and keep wear even.

How much weight will your mattress hold?

If you share your bed with a partner, your cumulative weight is likely to decrease the lifespan of your mattress. The heavier the weight on a mattress, the more it is compressed and, eventually, damaged.

So, if you find it’s time to replace your mattress, keep a few of these factors in mind before and after you make your purchase. Because they will help extend the lifespan of your most hardworking piece of furniture.

How Long Should A Mattress Last?

When buying a mattress, there is a lot of emphasis on how long it will last. You want something that you can use for years on end without having to make a trip to the store. Getting a mattress is an investment like any other, and you should thus get something that gives you value for its money.

Now, with mattresses, the issue of how long they will last is quite complicated. Thus, it is best to look at it in terms of how long you can derive comfort and support from it. In this way, you can estimate when it will be necessary to get another one and whether the subsequent purchase will give you your money’s worth.

Estimating a mattress’s life span is not only about money spent on the initial purchase. But instead, it also concerns your comfort levels. As the mattress comes to the end of its lifespan, you will notice that it will be quite uncomfortable and you will thus not get much rest at night. Additionally, this discomfort could earn you many trips to the doctor. And all this would lead to added medical bills, which you can avoid by taking the longevity of the mattress into account.

Back pains can result from a lot of things, including injuries from sports. However, did you know that mattresses can also be a cause of the same? A recent study shows that worn-out mattresses are to blame for some of the aches that people bear. If you have trouble falling asleep or wake up tired, consider changing your mattress and see whether there will be a change in your sleep patterns.

Now that you have seen the importance of having a sound mattress, let us get into the different types available in the market and how long they will serve your needs:


Mattresses should serve you for many years before you get a replacement. Some are good for five years, others ten and others for three. The lifetime depends on the material in place. The better the quality of the material, the more the mattress can last.

Most products on the market will serve you for about seven to ten years. After this, you get a replacement. But if you get the best in the market, you can have the mattress for ten years or more. It is important to note that though a material affects the lifespan of the mattress, the care given to the same will affect its durability.

It is recommendable that you should change your mattress every decade or so unless it is in good condition and can do with a few more years of use.


  • How long does a latex mattress last?

These mattresses are of exceptionally high quality, and they are the best choice for anyone looking for a product that will serve them for many years. On average, they last for fifteen years and could last longer with maintenance practices in play. They have the added feature of replaceable layers. In this way, if the layer wears out, you can replace it with another. Alternatively, you can flip the layers to allow them to wear out evenly, thus giving you comfort.

  • How long should a memory foam mattress last?

These mattresses are excellent in that they adjust to the shape of your body. Thus, you enjoy your sleep more. As compared to other mattresses in the market, they are less prone to sagging. However, that is not to say that it cannot happen. Under standard care practices, the mattress should serve you for a decade. You can add to its lifespan by flipping it to ensure that wearing out takes place evenly.

  • How long does an innerspring mattress last?

These mattresses will serve you for about seven to eight years. They feature thin coil springs which make them quite comfortable, especially in the early years. The disadvantage to these springs is that they eventually lose their strength, and they start sagging, thereby causing discomfort.

These mattresses do not feature springs, and they thus have more durability when compared to the conventional types. They can last for about seven to nine years. However, you can increase this lifespan by ensuring that proper maintenance practices are in play.

These mattresses go by this name as they borrow something small from the different types. For one, they have pocketed coils which offer support in the form of an innerspring system. Additionally, they have a soft layer such as what you would find in a latex or memory foam mattress. They are quite comfortable. The downside to them is that they wear out at a fast rate as compared to other products on the market.

They can last for as many as six years before it is time to make a replacement. However, some may last longer as it depends on what material is in the support core.

This mattress is suitable for anyone looking for a firm feel. When you fill the mattress up, it becomes rigid and quite comfortable. What’s more, these mattresses are portable, and you can use them on trips. The downside to them is that the air starts leaking after continued use of the mattress, and this makes them flop. What’s more, the built-in air pumps also get damaged over time, and this makes their use impossible. On average, you should expect five years of service from these products.

Now, this is the mattress you should get if you do not plan on using it often. It has low durability and can last for about five years with care practices in play. In most cases, you will find that a replacement is necessary within three to four years.

What influences the lifespan?

There are many factors that you should consider when thinking of how long a mattress will last. The guide above may point to three years. However, you should consider that this period is concerning what is standard. Here are some considerations to make:

  • Use

The more you use the mattress, the more wear and tear it will experience. Thus, where you rarely use a mattress, you can approximate that it will last longer than indicated in the guide.

Where you are heavy, you will exert a lot of pressure on the mattress. As a result, wear and tear will occur at a much faster rate as compared to if a lightweight person lay on it. Thus, for heavy people, the lifespan will be short, and the vice versa also holds.

You should watch out for what you place on the mattress. Suppose you use heavy and sharp objects around or on it, you will expose it to damage. The same goes for people who love eating and drinking on their mattresses. Doing so can lead to spillages, which would weaken the support core.

How often do you clean your mattress? Well, the presence of dust mites, bacteria, and other organisms will weaken the structure of your mattress. Thus, a mattress that gets cleaned often will last longer as compared to one that is not.

Is a replacement necessary?

There are many pointers as to whether you need a new mattress. Take an example of where you feel uncomfortable on the bed while lying on it. Or where you wake up with aches and stiffness. Sometimes, the need is more apparent. An excellent example, in this case, would be where you saw the effects of the wear and tear. It could be tears, holes, sagging, bumps, lumps, and other physical changes.

It could also be that when you sleep elsewhere, you feel more rested than you do in your bed. If that is the case, consider getting a new mattress. If the need is not that apparent, you could improve the state of your mattress by using the following tips:

  • Sagging

Suppose the mattress sags on one side or in the middle; there is a quick fix to this. Flip it over as this will allow even wear and tear.

Suppose the mattress smells of chemicals and fresh materials, you can air it out or wait it out. The odor is as a result of the chemicals used in the factory, and the smell should fade away in a few days. There is the alternative of using baking soda on it and vacuuming it out later.

If you notice dust mites and bed bugs on your mattress, you need to clean it. Also, take note that this is an indicator of poor hygiene. Thus, be sure to take measures to prevent such occurrences in the future. Vacuuming is a great way to get rid of these organisms. Alternatively, you can seal them in using a mattress cover. In this way, they will be unable to increase in numbers and will not crawl to the surface.

You can further increase the lifespan of your mattress through the use of a mattress protector and mattress topper. Additionally, ensure that you clean and flip it often. Using a warranty is not a guarantee of longevity. It is always best to go with materials. All the best!
