Nearly a third of your life is spent sleeping, and sleep quality is crucial to our health. This is affected by a lot of factors. Today, we’ll look to talk about one of those factors: your mattress quality. More specifically, it’s longevity and how it relates to your sleep quality. While I’ve only had to replace my mattress a couple of times throughout my life, clear wear and tear accumulated throughout the years, as my mattress got used more, its quality decreased, and my sleep deteriorated.

Let’s look at the factors that affect mattress longevity, outline the signs you’ll need to look out for before you replace them, and highlight tips and tricks to extend the lifespan of your mattress.

Key Takeaways

  • The lifespan of a mattress can span between 5-15 years based on several factors, but the key determinant is its type and material. 
  • The material used, your body weight, the type of mattress, your natural sleeping position and mattress maintenance practices will all affect how long a mattress would last.

How Long Does A Mattress Last?

The amount of time that a mattress lasts varies, but it mainly depends on the material of the mattress. On average, mattresses can last from as short as 6 years to as many as 10 years. However, some particular mattresses such as latex mattresses, can last up to 15 years or even more. 

You may ask yourself “How long does a mattress last?” because of how it’s manufactured, but at the end of the day, the longevity of your mattress is dependent on a number of factors affecting the physical quality of your mattress.

Why Mattresses Only Have A Specific Lifespan

Mattresses must be replaced over time because the structural integrity of the support and comfort materials for mattresses can degrade. This detrimentally affects their support and comfort over time. This is because foam deteriorates from oxidation, age, wear-and-tear, as well as chemical migration.

For instance, memory foam mattresses suffer from support loss, which is compounded by body heat and sweat. Moreover, the use of outdated mattresses has negative health consequences. Dust mites may thrive, thus producing allergens or mold from sweat, and this may cause respiratory problems. A lack of support from the mattress may also cause back and neck pain. 

With these, sleep quality deteriorates. This negatively affects one’s stress levels and overall mental and physical health, which may lead to potential health complications in the long run.Taking all this into account,you could say that mattress longevity is critical to sleep quality, your productivity, and well-being. Once you notice lumps or start to feel less rested, you might want to look into buying a new, more supportive mattress.

Factors That Affect the Lifespan of A Mattress

While mattresses are robust and built to last for several years, it’s important to understand the factors that can potentially accelerate mattress deterioration. If you understand these factors, it becomes easier in the future to make decisions regarding what mattress to choose, as well as how to maintain it. Knowledge and awareness of these conditions are key in this case.

That being said, mattress lifespan is dependent on several elements. These essentially boil down to mattress manufacturing, mattress use, and maintenance, and even the build of the person using them. By accounting for these to select the perfect mattress, you’re likely to have a higher quality of sleep.

Material and Type of Mattress

The material of a mattress is a major determinant of its durability. Different materials provide varying degrees of support and comfort. Memory foam, latex, innerspring, hybrid, and airbeds are all common mattress materials. Each material has distinct properties that appeal to various needs or preferences during sleeping.

For example, memory foam mattresses, are well-known for their contouring properties and pressure reduction. Latex mattresses are hypoallergenic and provide good support. Alternatively, innerspring mattresses provide excellent airflow and bounce, whereas hybrid mattresses mix various materials to produce a comfortable and supportive balance.

Being a side sleeper, I like to go for the latex hybrids as they’re very comfortable, last a long time, and have a lot of nice firm support without being too soft. Memory foam is good too - but I find that it does sleep hot and wear out fast.

Material quality and density are important considerations. Higher density foams and more robust components have a longer lifespan. It goes without saying that if you want to increase your mattress’ lifespan, you’ll need to invest in high-quality products with long-lasting materials.

Frequency of Use

Another important factor affecting a mattress’ longevity is its frequency of use. If a mattress is utilized every night, it will endure greater wear and tear due to tension and compression from a body’s pressure. This results in material fatigue over time, causing the mattress to be compacted and inadequate in terms of providing support.

This is seen when a mattress that is used on a regular basis will wear out faster than one that is only used infrequently, for example, in a guest room. Previously, I’ve considered placing a different type of mattress in a guest room that is of lower quality, yet affordable. Over the years, it has maintained structural integrity since it is not used as frequently.

Body Weight

Body weight can also affect mattress life Heavier people put more pressure on the mattress, causing it to compress more than a lighter person would. This compression might lead to decreased support and comfort over time.

For example, individuals with a higher body weight may choose a mattress made of thicker, more sturdy materials that can withstand more pressure over time. Furthermore, rotating the mattress more frequently may assist it to retain its support for a longer amount of time. 

Sleeping Position

The distribution of your weight on the mattress can be affected by your preferred sleeping position. Different sleeping postures place differing amounts of pressure on different parts of the body (1). Side sleepers, like me, for example, place more pressure on their hips and shoulders, whereas back sleepers distribute their weight more evenly. I’ve found that sleeping on my side helps out with body pain, as it provides better spine support and improves blood circulation. If you sleep on your side in particular, you may want to consider these best mattresses for side sleepers in Canada.

Mattress Maintenance 

Mattress maintenance is essential for extending the mattress lifespan. Proper care and attention can help prevent early wear and tear, retain the structural integrity of the mattress, and keep it comfortable and supportive. Additionally, keeping the mattress clean and well-ventilated prevents allergens and moisture from accumulating and degrading its quality over time. Overall, it also prevents unnecessary stress on the mattress materials, thereby ensuring prolonged durability.

Speaking as someone who has previously taken steps toward mattress maintenance, its effects absolutely can’t be denied. By taking the necessary steps, you will have a comfortable and high-quality sleep surface for many years by spending time and effort on mattress upkeep.

Types of Mattresses and When To Replace Them

There are numerous mattress varieties available, each with its own set of benefits for a customized sleeping experience(2). This section will help you understand when a mattress needs to be replaced. We’ll take into consideration wear and tear as well as maintenance.

The table below shows a number of mattress types, as well as their unique materials, characteristics, and average mattress lifespan indicating how often you should replace these(3). These can help you answer the question of how long does a mattress last.

Mattress TypeUnique CharacteristicsAverage Mattress Lifespan
InnerspringSteel coils are used to make innerspring mattresses, which collapse when you put weight on them. While there will be more bounce, due to coil limitation, you may need to replace them sooner.6-10 years
Memory FoamA memory foam mattress is a type of mattress consisting of viscoelastic foam. This softens and conforms to the shape of your body when subjected to heat and pressure.7-10 years
LatexA latex mattress is made of natural or synthetic latex, which is a robust and supportive material from the sap of rubber trees. It is popular for its resistance to allergens, as well as its durability, comfort, and breathability.10-20 years
HybridHybrid mattresses are made of foam and coils. The stability and bounce of an innerspring are combined with the softness of latex or memory foam.7-10 years
PillowtopPillowtop mattresses have a layer of cushioning on top of the bed that might be several inches thick. These tend to be more expensive.5-7 years
AirAirbeds are frequently constructed with foam layers, which allow them to not sag over time.2-7 years
WaterA water mattress is a water-filled bed or mattress. Its warmth promotes relaxation, soothes aching muscles, and relieves tension.10-15 years

Based on the conditions that you need, you may opt for a particular type of mattress also depending on where you’re based. If you’re a citizen of Canada and looking for a mattress made of memory foam, maybe you’d be interested in the best memory foam mattresses in Canada. Perhaps if you have a particular condition that’s giving you back pain, maybe you’d also be interested in the best mattresses for back pain in Canada.

I’ve personally been using a latex mattress for most of my life and highly attest to its breathability and durability in the long run. However, In terms of pressure relief, the memory foam mattress has performed the best for me.

While choosing the best mattress, I’ve also been advised previously that although a softer mattress can relieve pressure by conforming to your shoulders and hips, it still has to be just rigid and contoured enough to ensure that your spine is still aligned. This alignment and mix of characteristics is something that I’ve noticed that hybrid mattresses can do best.

Signs That It’s Time To Replace Your Mattress

Recognizing the indicators that your mattress needs to be replaced is critical for sustaining sleep quality and overall well-being. Here are some common indications that you should get a new mattress:

Pain and Discomfort

If you wake up with greater aches, pains, or discomfort that improves when you're not in bed, it could be a sign that your mattress is no longer providing adequate support.

Allergies or Irritation

A rise in allergies, asthma symptoms, or skin irritations may suggest a buildup of dust mites, allergens, or other particles within the mattress.

Excessive Noise or Motion Transfer

When the feeling of movement is highly prominent when another person is sleeping beside you on the mattress, this may indicate that the mattress's interior components have deteriorated.

Indentations and Uneven Surfaces

Visible depressions, bumps, or sagging areas where you sleep indicate that the mattress has lost support and is no longer supporting good spinal alignment. Although bumps in the feet area aren’t problematic, I find uneven surfaces around my back and shoulder to be deal breakers when it comes to replacing my mattress, as reduced sleep quality negatively impacts all aspects of my life. When I start feeling those indentations, I know it’s time to replace my mattress.

Disturbances During Sleep

If you're having more restless nights, tossing and turning, or waking up frequently, it could be because your mattress isn't providing enough comfort and support.

Changes in Body Weight or Lifestyle 

Significant changes in your body weight, health, or lifestyle may necessitate the use of a mattress with a different amount of support and comfort.

My Experience with With Mattress Lifespans

I’ve previously used mattresses up to the point where they are worn out - that takes about 6-8 years from what I can tell. This has led to buildup of allergy-causing fibers and dust to irritate my respiratory tract. I’ve also experienced losing sleep over several weeks due to back pain. However, this was stopped when I finally recognized these signs and replaced it. Doing so allowed me to get a good night's sleep and reduce pain.

If you see several signs in your mattress, it may be time to finally replace it. So don’t hesitate to pay a visit to the nearest mattress shop or have one straight delivered to your doorstep! If you are a resident of Canada and interested in having one delivered straight to your place of residence, you may want to consider these mattresses in a box, especially if you’re in Canada.

How To Make Your Mattress Last Longer 

Spill and Stain Prevention

A mattress cover can serve as a barrier, keeping stains and spills from reaching the mattress's surface. Stains can not only ruin the aesthetic of a mattress, but they can also promote the growth of mold or bacteria, which can harm the components over time.

Pro Tip: A mattress protector and high-quality bedding can help keep spills and dust off your mattress.

Control of Dust and Allergens 

Cleaning and vacuuming the mattress regularly can help remove dust, dead skin cells, and allergens that accumulate over time. These particles have the potential to degrade mattress materials and generate odors.

My general rule of thumb is to clean or vacuum my mattress at least once every 6 months.

Even Weight Distribution 

The manufacturer recommends rotating and turning the mattress to distribute weight and pressure evenly throughout the mattress surface. This approach keeps specific places from becoming overly compressed, which might result in drooping or uneven support.

Pro Tip: A mattress should be rotated every three to six months to distribute wear more evenly and prevent sagging in certain places.

Moisture Management

It is critical to keep the mattress dry for it to last. Moisture from perspiration or spills can infiltrate into the mattress layers, promoting mold and mildew growth and causing structural damage. In humid locations, proper ventilation and the use of a dehumidifier can assist keep the mattress dry.

To dry the mattress after spills and stains, one tip is to use baking soda. To prevent mold, vacuum and sanitize with alcohol. This has worked well for me in previous cases of preventing moisture and mildew on stained mattresses.

Following the Manufacturer's Instructions

The manufacturer provides unique cleaning recommendations for each mattress. Following these rules assures proper mattress maintenance and prevents damage that could void the warranty.

Preventing Sagging Through Support

Sagging, which is frequent in older mattresses, can be avoided with proper mattress care. Regular rotation and a solid bed frame help reduce permanent indentations and maintain the bed's stability. To minimize early deterioration and warranty voidance, a mattress requires strong support from an appropriate frame.

Aside from considering your mattress, at this stage, I also like to consider other factors in selecting my bedframe and how it will complement body size and mattress. This means looking into the size of the mattress relative to it, the appropriate platform, the headboard type, the aesthetic value, its durability, and many other factors.

Choosing Your Mattress Wisely

Choosing a mattress based on your sleeping posture improves comfort and longevity. Certain mattresses provide customized support based on your posture, weight, and health. Select a suitable type for improved spinal alignment, pressure alleviation, and sleep quality.

Consider also the size of the mattress. There are several sizes depending on the country where you are based; however, if you are in Canada, you may want to read about the different mattress sizes in Canada.

Ineffective Methods of Checking How Long a Mattress Will Last

There are a few ineffective methods of checking how long a mattress will last, which include checking only the price, warranty, and ignoring the type of mattress it is.

Price

Some sleepers only check the price of a mattress to judge how long it will last. The erroneous mistake they make is assuming that if a bed is more expensive, it will last longer. This is not always the case. Many mattresses are priced cost-effectively and are made of studier materials, outlasting expensive or high-end brands.

Warranty Length

Going off only the warranty length doesn’t always work when it comes to gauging how long a mattress will last. Yes, it is an excellent indicator, but judging by warranty alone and not looking at the material makeup can leave you with a bed that may be prone to sagging faster. Instead, always look at the warranty length, mattress materials, and density of the foams used.

Ignoring the Type of Mattress

Ignoring the mattress type can be detrimental to deciding how long a mattress will last. Assuming a latex mattress will always outlast a spring or memory foam mattress isn’t always correct. Other factors, such as the density of materials and the sleeper's weight, also play a role.

About four or five years ago, before I launched Comfy North, I had a bad experience choosing a mattress based on material alone. I had selected a memory foam mattress without considering its density or systems in place, or lack thereof, to support the middle of the bed. After a few months, it started to sag out on me. 

If I had known what I know now, I would have selected a mattress with extra firmness in the middle, such as a hybrid with reinforced zoned coils. That way, I could have avoided waking up sore and stiff.
