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 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.

How long does a mattress last?

My mattress is getting on in years. In fact, Bill Clinton was in his first term as president when I last bought a new one. Is it time for me to replace my mattress?

You’ve probably logged more than 30,000 hours in your bed, and your mattress has likely become less comfortable and less supportive. But there’s no set formula for determining when you need to replace a mattress. It might be time to buy one if:
•You regularly wake up tired or achy—you make Oscar the Grouch seem as cheerful as Mr. Rogers.
•You tend to sleep better away from home, than in your own bed. Are you planning unnecessary business trips or looking for any reason to go on a weekend getaway?
•Your mattress looks or feels saggy or lumpy—it needs go on the Abs Diet.
•You’re over age 40 and your mattress is five to seven years old. Remember, your body tolerates less pressure as it ages. As if getting older weren’t tough enough . . .

A mattress can be an expensive investment—we’ve tested models that cost in excess of $4,000—but if you treat your new one properly, it could easily last 10 years. Our advice:
•Don’t let your kids use your bed as a trampoline.
•Rotate your mattress. If you have a single-sided mattress (you sleep on only one side), rotate the mattress from end to end—that is, move the mattress 180 degrees. The foot of the mattress is now at the head, and vice versa.
If you have a double-sided mattress, rotate it as above, then turn it over so the bottom is now on top.
Perform these steps every two weeks for the first three months you have your new mattress, then once every two months thereafter. You’ll find illustrated instructions on a number of different Web sites.
• Use a bed frame that has a center support.

How Long Do Memory Foam Mattresses Last?

Table of Contents

Thelifespan of a memory foam mattress dependson the type of memory foam, number of layers, thickness, and density of layers, foundation layer properties, and construction strength.There are three types of memory foam namely the traditional, air cool, and gel. Traditional type is more suited if your body mass index is higher than normal and you want firm support for your spine and body. Gel memory foam has thetherapeutic propertiesfor healing lower back pain and aligning the spinal cord in a straight line. Air foam is forcontrolling your body temperaturewithin standard values and cooling your skin.

How Foam Density Effects The Life of a Mattress?

Density is a measure of weight per cubic foot. Low-density mattresses support 1.5LB per cubic foot. Medium density mattresses support 2-3LB per cubic foot. High-density mattresses can support 4 to 6 LB per cubic foot or even more. They have a high resistance to stress factors. It is because they distribute your body weight across the length X width and depth through the other supporting layers. Hence, the stress on individual layers will be relatively less.

Tensile Strength

Tensile strength is a measure of stretching limits. It is directly proportional to the elongation threshold when your body weight is placed on it. High-density mattress elongation could be hardly 10% to 15% of its original dimension. Medium density mattress elongates to 25%-30% of its original dimension. Low-density mattress elongates to 40% or more. Hence,reaching the breaking point takes more time for the high-density mattress compared to the other two types.Here, our research has been focused only on the memory foam layer. When it is supported by others like comfort layer, transition layer, spring layer, and base layer, elongation probability of memory foam layer gets reduced further. Hence,it can carry more weight per cubic foot and last longer than the other two types.

ILD Rating

Weight required for compressing 4” memory foam by 25%. Higher ILD rates can mean more weight capacity and extended lifespan.It also means the mattress is firmer in its construction.It also means the mattress can support your body weight without sinking in. However, it may not be practical to keep this factor always high since it can affect softness factor. Hence, the modern mattresses have introduced an additional layer of Gel memory foam over the polyurethane (PU) memory foam. ILD rating of gel foam is relatively low. But it transfers the weight onto the PU layer. Gelprovides softness for your body, while PU provides firmness. Combination of these two factors increases the comfort level while sleeping.

Rebound Pressure

It is called resilience. You might have seen children jumping and dancing on memory foam mattress in your home.They bounce on the mattress due to the rebound pressure offered by the foam.If this factor is higher, pressure relief points on the mattress can work more efficiently. Me top two memory foam layers can carry weight without experiencing an excess of stretching. It can also mean better body contour support which in turn increases coziness and comfort factors.

Thermal Conductivity

Heat absorbing gel memory foam mattress doesn’t retain it with its layers. It is due to increased risk of rupture within a few years. So, the design principles follow two methods of dissipating this heat.Transfer to the base layer or conversion into another form of energy for providing pressure and pain relief for your body while you sleep.The first form of transfer puts extra stress on the base layer. It can transfer heat onto bed frame if it is made of metal. When placed on a wooden bed frame, the heat gets trapped within the base layer. Since it has no way of retaining it longer, it transfers heat back to the top layer. This type of thermal circulation can also significantly reduce the lifespan of the mattress.

Hence,the best method is to convert heat into energy for pain and pressure relief.The sectional memory foam mattress consists of many horizontal sections from head to your feet. It can transfer the heat to the feet and legs section to induce faster and deeper sleep. Hence, the heat gets utilized. It also transfers part of the heat to the abdomen and hips section.If you sleep on back posture, it can help relieve lower back pain.Gel memory foam uses this heat for relieving the stress and eliminating fatigue factors from your body.

Shock Absorption

Low-density mattress can absorb shocks from abrupt posture change only for short duration. Then the cells start breaking down. You may have to change the foam layer frequently. Our experiments with a body weight of 198LBs and above showed significant differences in reaching breakdown point with time.High-density memory foam mattress with multiple layers can absorb shock better.By keeping the rebound pressure high, it is possible to reduce the impact of shocks on the foam layers.

Foam Construction

By increasing base foam thickness to 6” it is possible to provide better support for your body while resting. Transition foam of 3” and memory foam of 3” with gel memory foam of 3” thickness can increase the lifespan of mattresses at least by 5 to 6 years. It is not only due to weight distribution, but also support for different sleeping postures. If you are a side sleeper,the top gel memory foam can adjust its cells around your body to give you maximum support and comfort.PU foam can distribute your body weight around your body with spinal cord acting as a balancing point. Hence, the probability of losing your balance and changing to a back or stomach posture will be almost zero.

If you are a back posture sleeper, the density of PU memory foam will be higher, while the density of gel memory foam can remain the same. This sort of construction can also increase lifespan. If you happen to be a stomach sleeper,the thickness and density of transition and comfort layers have to be more.We have considered the BMI factor from an upper limit of the standard range to the low to high obesity levels. Practical experiments have shown that any mattress which can support higher BMI can certainly extend its support for normal BMI also.

Preventive Maintenance to Increase The Life of Your Memory Foam Mattress

The finest range of quality memory foam mattresses can have a long life when you can follow certain simple preventive maintenance procedures.They can protect your mattress from mold and mildew, dust and dirt, germs and microorganisms.Maintenance keeps your mattress free from moisture and dampness due to sweating.

Vacuum

Vacuum your memory mattress once a week to remove dirt and particles. Make sure you have used the upholstery attachment to regulate pressure.If the mattress has a zipper, you can open it and vacuum the internals also.Such cleaning is highly useful for assembled mattresses.

Spray

You can use antifungal and anti-infectious sprays to eliminate the harmful elements from your memory foam mattress. But you have to make sure they are free from moisture and dry off naturally.

Clean

Cleaning agents without moisture content such as vinegar can help in removing stains. You may also use the off the shelf products after reading the ingredient specifications.

Drying the memory foam mattress in the open air without exposing it to the direct sunlight is one of the simplest and safest methods after cleaning. It will also eliminate the pungent odor of the spray

How Long Do Memory Foam Mattresses Last – Summary

BMI VS Mattress Density

If your BMI is within the healthy range and you sleep alone, you may opt for amedium density mattress with three foam layers. If you are a couple with healthy BMI, you can opt for thesame type of mattress with high resistance for motion transfer.If your BMI is anywhere near the stage of obesity, it is better to opt for a high-density mattress.

Best Practices

Make sure you check the above-listed parameters in detail before placing an order. Then you can select the best mattress that supports your sleeping posture, Body Mass Index (BMI) and usage pattern. If you constantly change your posture during sleep, it is better to opt for Hybrid /composite mattress with four to five layers of foam. The top layer being Gel memory foam and the layer beneath that being PU foam.You can opt for a mattress company which gives you a free trial period of at least 15 nights.Then you can evaluate the mattress quality and durability.

How Long Does A Mattress Last? When Is It Time For A New One

Table of Contents

It is usually pretty easy to tell when it’s time to replace an innerspring mattress because they become squeaky, less responsive, and may even start to poke you in areas where the coils have worn down considerably. However, with all of the different materials and innovative mattress designs available on the market today, it can be hard to remember what we should expect from your mattress as far as its lifespan is considered. So we ask the question, how long does a mattress last?

Many different mattress companies are offering warranties with their products that can last for 10 years, 20 years, or even a lifetime. This has often made me wonder, can a mattress last 10 years? Can a mattress last 20 years? I highly doubt they can last a lifetime. Considering people spend a third of their lives in bed, on average, this just didn’t seem possible to me. So if you are like me and have also asked yourself the same questions, continue reading to find out what I learned!

The Lifespan of Your Mattress

Not all mattresses are alike, but even the most durable mattress will not last forever. The expected lifespan of different types of mattresses relies on a few factors.

First, we will discuss the different types of mattresses individually because the material used in construction largely determines the lifespan overall.

After that, we will examine the traits that should be considered regarding the lifespan of all types of mattresses.

This combined information will enable you to make an accurate assessment and determine if it’s time for you to upgrade your current bed, or not.

1. The Materials Used

The most important thing to consider when evaluating the mattress lifespan is, what materials were used to to make the mattress? Different materials deteriorate faster than others.

Ultimately, this is the key trait to think about when asking “How long does a mattress last?” When comparing memory foam vs spring or any other material used, the type of mattress you have will reveal the most accurate estimate of how long it will last.

a. How long does a memory foam mattress last?

We recommend replacing your memory foam mattress after no more than 10 years.

Memory foam was invented by NASA to sustain extreme force and high levels of pressure. As a result, it is extremely durable and makes an excellent shock-absorbent material that is usable in many different products, like mattresses.

When purchasing a memory foam mattress, it is important to keep the thickness and density of the foam in mind. A higher density will provide a more durable level of support. A density level of 3.5 to 4 lbs./ft³ will provide the support necessary for most people. If you are a heavy person or have a large frame, aim for a density level of 5 lbs./ ft³ or more to prevent premature wear and tear.

You will know it’s time to replace a memory foam mattress when it starts to sag and show an indentation of greater than 2 inches. It will also be less responsive and take longer to decompress after years of extended use, alerting you to the end of its healthy use.

b. How long does a latex mattress last?

We recommend replacing your latex mattress after no more than 10 years.

Latex mattresses are very durable and will last you a long time, especially if you get one with a high-density level. Natural latex is more durable and has more elasticity than synthetic latex so it will typically last longer. Synthetic latex mattresses are more affordable so you may want to consider hybrid latex options that blend both types to provide the consumer with a lower price.

Some latex mattresses open up with a convenient zipper and you can replace the top layer which will allow you to lengthen the bed’s lifespan by several years.

You will know it’s time to replace your latex mattress when it sags, loses its resiliency, or becomes uneven on the surface.

c. How long does a pillow top mattress last?

We recommend replacing your innerspring mattress after no more than 8 years.

Generally speaking, a pillow top or an innerspring mattress will need to be replaced more frequently than other types made from foam or latex. The individually wrapped coils inside tend to wear unevenly causing large dents and sagging after continued use, especially if you always sleep in the same location on the mattress.

If you prefer innerspring mattresses, often they are more affordable, get one with a higher coil gauge. The higher the gauge number, the thicker the coils. Thick coils denote longer-lasting durability and a firmer feel overall. Another way to maximize the lifespan of an innerspring mattress is by purchasing one with a pillow top or euro top on it. This will provide an extra layer of comfort and prevent premature sagging to some extent.

2. Frequency of Use

Second, consider how often the mattress is used. The majority of people spend every night in their bed. However, if you are considering replacing a mattress in a spare bedroom, or if you travel a lot, you will want to consider how often it gets used. If it frequently is empty then it will last for many years longer than the mattress you sleep in every night.

Couples who do not live together and frequently spend time sleeping at their partner’s house should add some additional years to their bed’s lifespan. Of course, this could pose other issues which we will address in the next section.

3. Body Type and Number of Sleepers

Third, consider your body type and whether or not you sleep with a partner. If you have a large body type, are tall, or overweight, how long you should keep a mattress will noticeably decrease. The more pressure that is applied to the mattress, the faster it will start to show wear and tear. The materials deteriorate as they are used and the more pressure that is applied, either by yourself or with the additional weight of your partner, the faster it breaks down.

The breakdown of materials happens the fastest in the top comfort layers. They are the softest and most responsive layers but are unfortunately the most susceptible to compression and deterioration from excessive weight as well. When this happens the inner layers of the mattress may remain firm and supportive but without the top comfort layer or layers functioning properly, you will start to notice some of these negative side effects over time: improper back and spine alignment, less comfort, decreased pressure point relief, and increased firmness overall.

If you have a large body type or are overweight, you may want to consider purchasing the best mattress for heavy people as these cater specifically to your requirements. Buying a more specific mattress will enable you to keep it for much longer without sacrificing comfort or longevity.

4. Maintenance

Fourth, look back and consider how you care for your mattress. The amount of effort you spend caring for your mattress will also affect the lifespan. I know it seems pretty obvious but most people could increase their mattress cleaning regimen in multiple ways to help boost the longevity of their mattress. The more you clean your mattress and preserve the original integrity of the materials, the longer it will serve you before it starts to show natural wear and tear.

Make Your Mattress Last Longer

Here are a few easy things you can do so your mattress lasts longer. Take a look at these easy tricks that you may, or may not already be doing which will ensure you are giving your mattress the best opportunity to perform on a high level, and for an extended period.

  • Use a mattress protector, especially if you have kids.Preventing liquid from penetrating the inner layers of the mattress will keep it clean and prevent rapid degradation of the materials.
  • Wash your sheets frequently.They serve as a barrier which protects the mattress from dead skin cells and spills.
  • Don’t eat in bed.I know you think you can be careful but don’t test it. It can be very difficult to get food completely out of the material on your mattress.
  • Don’t let your pets sleep in your bed.Instead, get them their own. There are many reasons why pets shouldn’t be allowed in your bed. An example is that pets can drool and shed which only adds to the breakdown of materials while simultaneously creating an odor that is near impossible to get rid of.
  • Clean and deodorize it.Sprinkle baking soda on the surface of your mattress occasionally, let it sit for about 30 minutes to an hour, and then air out or vacuum it up. The baking soda will naturally extract and absorb and moisture from within and leave it smelling fresh.

How Long Does A Box Spring Last?

Do box springs wear out? They sure can! For the most part, you will know if your box spring wears out because the frame will give and no longer provide your mattress the even support it needs to maintain comfort. Often it will drastically sag on one side or in a particular corner leaving you with a slanted surface that is no fun to sleep on. If a box spring gets wet it could develop mold or bacteria which is another sure sign that it is time to dispose of your mattress and replace it. You can try to air it out but if it is not dried fast enough, then it might need replacing. You can simply get a different kind of frame like a platform bed that is functional without the need for a box spring.

Signs That You Need A New Mattress

Now that you know the estimated life expectancy of the most common types of mattresses, it’s important to remember that these are just guidelines. Regardless of what the estimates say, there are a few signs you should look for that will indicate it’s time to replace your old mattress.

Let’s have a look at some signs that mean you need a new mattress:

  • Sagging, lumps, and/or indentations:If your old mattress has visible sagging, indentations greater than 2”, or it becomes lumpy you should consider upgrading to a new one.
  • Sore and achy muscles:If your muscles and joints are sore or ache in the morning that is a good sign it’s time for a new mattress.
  • You sleep better in another bed:If you find you sleep better in another bed, like in a hotel or at a friend or lovers, it could be a sign you need a new mattress.
  • Poor quality of sleep:If you wake up feeling tired and less refreshed than normal because your quality of sleep is poor it could be time to get a new mattress.
  • Water damage:If your mattress gets wet you will most likely need to replace it. With some mattresses, you can air it out or it can be dried out in a rapid fashion so you can avoid replacement but often this is not the case. Small spills can usually be cleaned up but wet mattresses are said to be the best breeding ground for bacteria and mold which can be harmful to your health so it should be taken very seriously.

In Conclusion

How often you should buy a new mattress depends on what type you have, and how you choose to use it. Aside from the most determining factor, the material used, you must also consider how often you use the mattress, whether or not you sleep with a partner, your personal body size, and the amount of effort you spent on preventative care like light cleanings and frequently washing your sheets.

So, how long does a mattress last? Generally speaking, our best guess is about ten years, minus some years for the variables previously outlined in this article. Most often, it will be easy for you to notice changes in your mattresses integrity and overall structure that signal it will not last for much longer.

The most important thing is that you get a good night’s sleep and wake feeling rested and rejuvenated in the morning. If this ceases to be the case and you have had your bed for a long time, it’s most likely time to purchase a new mattress.
