Dr.-Dimitar-Marinov-Profile-Picture-Bedroom-Style-Reviews

If you’re trying to find out how long a mattress will last then you’ll get different numbers depending on the website that you visit – with mattress retail sites often exaggerating the figures and trying to lead you to believe that a mattress will last as long as its warranty length.

So how long do mattresses really last?

Most regular spring and cheap polyfoam mattresses can last 5-7 years on average. High-quality memory foam mattresses can last 5-8 years. Hybrid mattresses can last 6-10 years. Organic/natural latex mattresses can last 6-12 years.

The rest of this article reveals how long different types and brands of mattresses will last, as well as the 5 factors that influence how long a mattress will last, 3 ways to make your mattress last longer, and the 5 signs that you need a new mattress.

Most Mattresses Last 5-7 Years On Average

Mattresses last 5-7 years on average – which typically falls short of the industry standard 10 – 25 year warranty length because lengthy warranties are often used as marketing tools that only cover you in the case of defects and not regular wear and tear.

Instead, the true lifespan of a mattress will vary depending on the qualities of the materials used, the design, how well you look after the mattress, the weight being placed on the mattress, and other subjective factors.

To help ease the confusion, I have listed how long different types and brands of mattresses are expected to last based on their qualities below:

Mattresses Lifespan Varies By Type

Although the average lifespan of a mattress is 5-7 years, some mattresses may last longer or less than this depending on the design of the mattress and the materials used.

Below is a detailed breakdown of how long each type of mattress is expected to last:

1: Regular Mattresses Last 5-7 Years

A regular mattress that’s made from springs and/or polyfoam should last 5 to 7 years.

2: Spring Mattresses Last 5-7 Years

A spring mattress with a continuous, Bonnell, or offset coil support core should last approximately 5-7 years, whilst a spring mattress with individually wrapped pocket coils may last slightly longer due to the way in which it can disperse your body weight more evenly and reduce the effects of wear and tear.

3: Hybrid Mattresses Last 6-10 Years

Hybrid mattresses make for some of the longest-lasting mattresses and may last up to 6-10 years or more with the right care if the materials are of high quality and the mattress is well designed.

4: Foam Mattresses Last 5-7 Years

Regular foam mattresses made entirely from cheap polyfoam are typically some of the shortest lasting mattresses and may struggle to last longer than 5-7 years and still provide a comfortable and supportive sleep surface.

5: Memory Foam Mattresses Last 5-8 Years

Memory foam mattresses that feature high-density memory foam in the upper layer and polyfoam in the lower support core can last up to 5-8 years if the design is good and the materials are of high quality.

6: Latex Foam Mattresses Last 6-12 Years

Mattresses made entirely from latex foam that have a high organic or natural latex foam content are some of the most durable and long-lasting mattresses that you can buy and can last up to 6-12 years or more with the right care.

7: Pillow Top Mattresses Last 5-7 Years

Pillow top mattresses typically last between 5 and 7 years depending on the quality and design of the pillow top, the upper comfort layers, and the support core – with poor quality pillow-top mattresses typically compressing easily, becoming lumpy, and wearing out faster.

8: Box Spring Mattresses Last 5-10 Years

Mattresses with a box spring may last between 5 and 10 years or more depending on the type of mattress being placed upon the box spring (hybrid, spring, foam, etc) and the quality of the box spring frame itself.

9: Air Mattresses Last 3-5 Years (Infrequent Use)

An air mattress that’s used infrequently may last up to 3-5 years, whilst an air mattress that’s used every night or very regularly may only last a few months before it develops a leak.

10: Crib Mattresses Last 3-5 Years

A crib mattress will last approximately 3-5 years with the right care, with crib mattresses that are waterproof and/or are resistant to mold having the potential to last the longest due to their ability to resist degradation more effectively.

11: Futon Mattresses Last 5 Years

A traditional futon mattress that’s placed directly on the floor and used regularly may last up to 5 years, with modern fold-out futon mattresses that work with a frame potentially lasting longer than 5 years if the mattress and the frame are in good condition.

12: Horsehair Mattresses Last Up to 80-100 Years

Some of the finest quality horsehair mattresses may last up to 80-100 years due to the exceptional qualities of the materials, with prices starting at a few $1,000s and topping out at the $200,000 mark.

13: Mattresses in a Box Last 5-12 Years

Mattresses in a box can last between 5 and 12 years or more depending on the type (latex, hybrid, memory foam, etc) and the quality of the materials used.

14: Water Beds Last 5-10 Years

Water beds made from PVC may last for up to 5 to 10 years or more with the correct care.

15: Double Sided Mattresses Last 5-7 Years

Double-sided mattresses typically last approximately 5-7 years depending on the materials and the design – with the double-sided feature not being an exclusive guarantee that the mattress will last any longer than a single-sided ‘no-flip’ mattress.

16: No-Flip Mattresses Last 5-7 Years

No-flip single-sided mattresses can last up to 5-7 years or more depending on the materials used and the design – with the single-sided design not being an exclusive guarantee that the mattress won’t last as long as a double-sided mattress.

5 Factors That Affect How Long a Mattress Will Last

The 5 key factors that influence how long a mattress will last are the design, material quality, body weight of the sleeper, frequency of use, and the firmness of the mattress.

Below is a more detailed explanation of each factor.

1: Design – Hybrid and Latex Mattresses Last Longer

Hybrid spring-latex and all-latex-foam mattresses are typically the most durable mattress designs (approximately 6-12 years), whilst all-polyfoam and regular spring mattresses have the shortest expected lifespan (around 5-7 years), and good quality memory foam mattresses lasting around 5-8 years on average.

2: Material Quality – High-Density Foams Last Longer

Whilst the design of the mattress can be a guideline for the expected lifespan of the mattress, this is only true if the materials used to actually make the mattress are of good quality.

The table below grids the qualities that you should look for when selecting a mattress for maximum longevity:

Mattress TypeIdeal Qualities
HybridIndividual pocket coils + high-density memory foam or organic/natural latex foam top layer
SpringIndividual pocket coils + high-density foam top layer
Memory foamMinimum foam density of 4-5 PCF
Latex foamHigh organic or natural latex content (with little or no synthetic SBR latex)
PolyfoamMinimum foam density of 1.5 – 1.7 PCF

3: Body Weight – More Weight Wears Out a Mattress Faster

The more weight that a mattress is exposed to, the greater the risk that the mattress materials will wear out and thus reduce the lifespan of the mattress.

If you weigh more than 230 lbs then as a general rule, you should go for a hybrid mattress that’s at least 10-12 inches thick with at least a minimum firmness rating of medium (consider medium-firm or firm if you’re a front or back sleeper to help maintain good posture) to guard against excessive material compression and potentially maximize the lifespan of your mattress.

4: Frequency of Use – Less Use Increases Longevity

If you use a mattress every night, then you should expect its lifespan to shorten relative to a mattress of equal quality that’s used less frequently – such as a mattress that you only use occasionally in your guest room.

5: Firmness – A Firmer Mattress May Last Longer

It’s possible that a firmer mattress may last longer than a softer mattress of equal material quality because the increased surface tension may help to guard against excessive material sinkage which may otherwise lead to faster material degradation and a mattress that doesn’t last as long.

However, you should NOT buy a firm mattress just because you think it might last longer – firmness selection is more important relative to how comfortable you’re going to feel in the mattress in the context of your body weight and dominant sleeping position.

Selecting the right mattress firmness isn’t an exact science, but if you’re a front, back, or side sleeper in the 130 – 230 lbs range (around 80% of sleepers) then a medium level of firmness should be comfortable for you.

You may wish to consider a medium-soft, soft, or extra-soft mattress if you’re a lighter weighted side sleeper under the 130 – 150 lbs range for more pressure relief and comfort.

Conversely, if you’re a heavier weighted front or back sleeper over 200 lbs then you may prefer a medium-firm, firm, or extra-firm mattress to help maintain ideal posture.

3 Ways to Make a Mattress Last Longer

To make your mattress last longer, you should rotate it every 3 months, use a compatible frame, and apply a mattress topper.

More details below:

1: Rotate Your Mattress to Distribute the Weight

Rotating your mattress 180 degrees every 3 months can help to extend the life of the mattress because it distributes your body weight more evenly across the surface of the mattress to help lessen the risk of indenting and sagging that could make the mattress uncomfortable and shorten its lifespan.

If you sleep as a couple with different body weights, regular mattress rotation is especially important because it helps to even out the pressure that your mattress is being exposed to over time.

However, unless you have a double-sided mattress, you should NOT flip your mattress because turning over a mattress with a single-side design means that you’ll be sleeping on the uncomfortable support core which can lead to mattress damage and will almost certainly void the warranty.

2: Use the Correct Frame for Even Support

You should always buy a compatible frame to go with your mattress to ensure that the mattress is well supported and therefore less likely to degrade due to uneven pressure being placed on the materials that may cause degradation and a reduction in the life expectancy of the mattress.

Using the correct frame can also cure a noisy mattress, increase comfort, and prevent aches and pains.

3: Apply a Mattress Topper to Cushion Your Weight

Putting a mattress topper with the correct firmness relative to your sleeping style over the top of the mattress can help the mattress to last longer because, in addition to protecting the mattress from spills and stains, it can cushion your body weight more effectively to combat material degradation.

You can also use a mattress topper to temporarily fix a broken mattress with springs poking through the top if you’re not currently able to buy a replacement mattress.

5 Signs That You Need a New Mattress

The 5 signs that you need a new mattress is that the mattress is more than 5-7 years old, the mattress is sagging, you’re waking up in pain, your allergies are worse, and other beds feel more comfortable.

More details below:

1: Age – Mattresses Older Than 5-7 Years Need Replacing

Most mattresses will need replacing every 5-7 years if they are being used every night.

You may be able to continue sleeping in your mattress for longer than this but you should watch out for the other tell-tale signs listed below that your mattress really does need replacing.

2: Sagging – Worn Out Mattresses Lose Their Shape

If your mattress exhibits a sag of 1-1.5 inches or more across the surface of the mattress then this is a sign that you need to replace your mattress because it could be causing bad posture.

More concentrated indents can also lead to pressure points and discomfort.

The video below shows you how to identify a sagging mattress easily:

3: Pain – Worn Out Mattresses Can Cause Discomfort

If you’re waking up with back pain or stiffness in your body that eases off as the day progresses and then returns the next morning, then this is a strong indicator that your mattress has worn out and is no longer suitable for your body type and sleeping position.

In a study where 59 subjects with minor musculoskeletal sleep-related pain who were sleeping on a mattress with an average age of 9.5 years switched to a brand new, moderately priced, medium-firm mattress, back discomfort was significantly reduced (with gradual improvement over 4 weeks) and sleep quality also increased [1].

4: Allergies – Worn Out Mattresses Harbor Allergens

If you are experiencing sneezing, red eyes, and/or a stuffy nose when lying down on your mattress then this could be a sign that allergens like dust mites have built up inside the mattress.

You may be able to resolve this by washing the cover, replacing the sheets, or using a hypoallergenic mattress protector.

But if this doesn’t fix the issue, then it may be the case that the support core is packed with allergens and a new mattress is required.

5: Other Beds Feel More Comfortable

If you notice that you sleep more comfortably in a different bed – such as a hotel mattress for example – then this could be a sign that your mattress has worn out and needs replacing.

Related Questions

Below are the concise answers to some of the questions related to how long a mattress will last.

Do Mattresses Last As Long As the Warranty?

Most mattresses will NOT last as long as the warranty because the average lifespan for a mattress is 5-7 years whilst the average length of a mattress warranty is 10 years.

Will a Firm Mattress Last Longer?

A firm mattress may last longer than a softer mattress because the increased surface tension may help to combat material compression and increase durability which may increase the lifespan of the mattress – especially when used by heavier weighted sleepers over 230 lbs.

Can a Mattress Last 20 Years?

It’s unlikely that the average mattress will last 20 years and still be comfortable – most mattresses will last 5-7 years on average, whilst some high-quality hybrid and latex foam mattresses may last up to 10 years or slightly longer.

Conclusion: Most Mattresses Last 5-7 Years

Despite the often exaggerated claims made by mattress companies, most mattresses will need replacing after 5-7 years – with some higher quality models potentially lasting for up to 10 years or a touch longer.

Make sure that you don’t judge the potential lifespan of a mattress based on the length of its warranty because warranties only cover certain defects and replacements/repairs will not be issued for regular wear and tear.

If your mattress is more than 5-7 years old, is sagging, is causing you pain, and/or is making your allergies worse then the best course of action is to buy a new mattress.
