How we Build your Mattress

Sealy Express Mattress:

This super-stretchable knit cover with rayon fibers helps provide cool comfort.

Cooling, copper-fused memory foam works as a natural conductor, moving heat away from your body.

High-density gel memory foam is ideal for all sleeping positions and delivers long-lasting support.

Exclusive to our 12" model! Sleep in total bliss thanks to this high quality cushioning foam. Available in a range of comfort preferences.

A firmer foam that creates a solid foundation for better sleep.

We’re happy to report that your Sealy is both designed and assembled in the U.S.

Sealy does not include chemical fire retardants, but uses an industry-standard “fire sock.” We put each mattress through grueling flame-resistance testing, and it passed. Rest assured…

When your Sealy arrives, there may be a slight scent. Think of this like the scent in your new car or new furniture. It’s the result of the cells in the foam opening. The most important thing to know is that the scent will disappear within a day or two.

Product Care

You can spot clean your cover. The cover is not meant to be taken off or washed. If you are trying to remove a stain, dampen a cloth (do not saturate) with a mixture of water and delicate-friendly detergent. Gently scrub the spot and let air dry.

If you’re not happy with the feel of your new mattress, you have the option to return it. But we recommend sleeping on it for 30 nights—it can sometimes take a while to get used to a new mattress, especially if your old mattress was worn. But of course you can return it at any time during the first 100 nights.

You can use any sheet set designed to fit your selected mattress height. For the bottom sheet, a fitted sheet with strong elastic fitted works best.

Mattress Warranties: What You Should Know – 2018

Unbiased Research Based on Data From 4,300 Mattress Owners

Avoid The Void

Mattresses can and often do have their warranties voided due to the use of an improper foundation / frame and the presence of staining, soiling or fluid penetration.

Improper foundation / frame

An improper foundation / frame can result in premature wear and sagging of the mattress. Read your warranty’s foundation / frame guidelines and follow them to the letter. Mattress companies do not give leeway on this issue; your foundation / frame either meets their warranty guidelines or it doesn’t.

Staining, soiling and fluid penetration

These can fully void a mattress warranty. Even if the staining, soiling or fluid penetration is not near a defective area, such as where sagging is located, the warranty will probably not cover the sagging.

Therefore, it is wise to use a mattress protector / pad from the first night onward. See mattress pad reviews for the top-rated pads.

Warranty Length ≠ Mattress Lifespan

Most mattress warranties are for a length of 5, 10, or 20 years. Our research strongly suggests that in most cases you shouldnotbelieve that your mattress will last the length of its warranty with regular, everyday adult use.

Sleep Like The Dead collected data from over 4,000 owners regarding how long they kept their mattress or how long they reported that it maintained most of its original comfort and support. This data was then compared to the length of the mattress warranty.

The results suggest – as the table shows – that the useful life of a mattress is often a fraction of its warranty length, and the fraction becomes smaller as the warranty length increases.

Warranty LengthAverage Useful Lifespan
5 years4.7 years
10 years7.1 years
20 years8.2 years

Keep in mind that our findings are true only in general. In other words, individual brands, individual models, and individual mattresses may perform somewhat better or worse. (Refer to the rating page of a particular mattress for information on its expected lifespan.)

Also, our findings suggest that there is indeed somewhat of a correlation between warranty length and the quality / durability / longevity of a mattress. In other words, good mattresses usually have longer warranties, while not-so-good mattresses usually have shorter ones.


The main complaint people have with their mattress is sagging – especially in regard to innerspring beds in general and to a lesser extent foam, latex and air mattresses.

Owner experience data suggests that even moderate sagging can and often does result in less comfort and support. It may also cause back pain, especially for side and stomach sleepers. (See mattresses and pain for more analysis.)

As a result, mattress shoppers should pay special attention to how sagging issues are covered by the warranty. Most warranties will cover sagging only when the problem becomes severe enough, that is, when it reaches a certain depth.

For example, innerspring mattress warranties will often provide coverage for sagging beginning at a depth of 1.5 inches. By contrast, some memory foam mattress warranties, including Tempur-Pedic’s, will provide coverage for sagging beginning at a depth of .75 inches. In other words, innerspring bed warranties often require twice the depth of sagging that these memory foam bed warranties require before coverage kicks in.

It Will Cost You

Making a warranty claim and replacing a mattress under warranty can be expensive to the mattress owner.

There can be a fee to have someone come to your home to inspect the condition of your mattress to determine if it is eligible for warranty coverage. If it is eligible, there will be a fee to take the defective mattress away and to ship a new or repaired mattress to you. Given the heavy weight of many mattresses today, this fee may be substantial.

In addition, depending on the age of the mattress and the warranty terms of proration, you may have to pay a percentage of the replacement or repair costs.

Long Warranties Often Have A Catch

Mattress warranties with impressive length, namely 15 years or longer, usually have a catch. For example, most airbeds including Sleep Number have a 25-year warranty. This causes many owners to wrongly believe that if any manufacturer defect pops up in the next 25 years, the problem will be covered at little or no cost to them.

The whole story is that non-prorated coverage (coverage for which there is no cost to the owner to repair / replace the bed) often ends after just two years. If something goes wrong with the airbed after this time, coverage is prorated which means the owner will often need to pay at least 20% of repair costs.

Therefore, make sure to read the fine print of a mattress warranty that’s over 10 years.

Normal Wear Not Covered

Mattresses are discarded for a variety of reasons, but the main reason not surprisingly is usually related to a loss of comfort and support that occurs through normal wear.

As is true for virtually all product warranties, normal wear is not covered under mattress warranties; only faulty workmanship / materials as defined by the manufacturer are covered. These defects are problems that can be objectively measured or observed, such as sagging depth. Problems not objectively measurable or clearly observable, such as excessive softening or loss of support, are not commonly covered under warranty.

Better Business Bureau Rating

A mattress warranty is only as good as the manufacturer’s willingness to honor it. Often a mattress manufacturer’s BBB rating and or the number of BBB complaints from consumers in regard to warranty-related issues can be a good indicator of how well the company stands behind its warranty.


Protecting your investment in healthy sleep

A warranty is your protection against defective workmanship – it is not a guarantee of product life or more important, of comfort life. Even though your current bed may have a warranty of 10 to 15 years, that doesn’t mean it will provide maximum comfort and support for that long. If your body changes or your life changes, you may need a new bed.

Sealy Warranty

Sealy® warrants our sleep systems are free from any defect in workmanship or materials. We source only the best quality and finest raw materials to manufacture our sleep systems.

This promise is backed by our commitment to continually improve our products and services through the application of a quality management system, as guidelined by the ISO (International Standards Organisation) quality management principles.

Limited Warranty & Guarantee

What does a Limited Warranty & Guarantee mean?

  • A factory guarantee repair or replacement period is against faulty workmanship and faulty materials, not extending to damage caused by normal wear and tear, abuse, misuse or negligence.
  • A service warranty period is the balance of the period outside of the guarantee period where the cost of repair or replacement is borne by the customer on a pro rata basis for the remainder of the service warranty period.

How long does a Sealy mattress last?

Thinking about investing in a new mattress? When it comes to weighing up your options, an important factor to consider is how many years a mattress will last. Naturally, a product’s life will determine your return on investment. For example, if you pay $5,000 for a mattress that you keep for five years, you’re only getting half as much value compared to if you bought one that lasts for ten years. As you can see, it’s an important number to know.

Sealy Posturepedic, awarded Canstar Blue’s "Most Satisfied Customers" Award for Mattress Brands in 2018 and 2017, works with an industry-leading Research & Development team that is dedicated to designing and testing quality bedding. But just how long does a Sealy mattress last?

The Sealy Guarantee

While some customers have claimed their Sealy mattress has lasted them three decades, you can count on it to last the length of the Sealy Guarantee – that is,ten years.

This guarantee covers coils or wires in the mattress that are loose, broken, protruding or torn. It also covers the foundation if wood splits in the frame, modules compress, legs and castors fail, or foundation wires break through any fabric.

With this guarantee, you can rest assured that you will have a mattress in good working condition for the next decade.

Sealy mattresses are built to last

Sealy has invested in research and development to offer optimal sleep support and comfort to customers. This includes selecting materials that are durable, functional, luxurious, and tested to ensure the mattresses work as they should.

When looking into how Sealy mattresses are made, you will find that each state in Australia has its own mattress factory in place to meet the local demand. You won’t find any warehouses full of imported mattresses because each one is made to order. This investment into local manufacturing supports the economy and its local people; employees return the loyalty with devotion to their craft.

Once the mattresses are made, they undergo rigorous testing by the Sealy Research and Development Centre, a NATA accredited testing facility. Each mattress must comply with the stringent Australian quality standards.

This process includes testing the raw material to insure all components of the bedding meet both Sealy’s own as well as the national standards. Components undergo an initial series of tests, followed by ongoing testing to ensure consistent performance. In addition to the raw materials, Sealy tests the finished product, too. Every piece of bedding that leaves manufacturing adheres to benchmarks for durability, comfort and support.

How do you know when your mattress needs to be replaced?

Aside from being a place to sleep at night, your mattress serves another important purpose: to provide the necessary support to ensure your body stays properly aligned at night. This is critical so your muscles can relax and you get a restful night’s sleep.

Over time, the infrastructure of the mattress will begin to deteriorate. As a result, the support it offers may also decrease. When that happens, you may find it’s harder to get comfortable, perhaps start tossing and turning at night, and could even wake up with pain (often in the lower back or on pressure points).

If you are experiencing any of these symptoms, think about how many years it has been since you purchased your current mattress and inspect it for signs of sagging or deterioration.

Tips to make your mattress last longer

Know the Guarantee information

First, read the guarantee information so you understand which parts of the mattress are covered. Then, periodically check to see if any of those parts malfunction – if they do you can take action to quickly repair them. It also helps to be aware of what voids the warranty so you can take preventative action.

Moving the mattress

When you receive your mattress, carry it on its side with the help of another person. Be sure that it never gets bent. Additionally, while there are handles, they are not for lifting or carrying the mattress. They are only for positioning it once it’s on the foundation.

Don’t jump on it

Once the mattress is in place, never let anyone jump on it. While it will be soft and a bit bouncy, jumping can damage the mattress’s infrastructure so is considered abuse. If it’s damaged from abuse, the warranty will be voided.

Keep it clean and dry

Another important tip is to keep the mattress clean and dry. Purchasing a mattress protector is a great way to do this. Furthermore, a waterproof sheet or cover to go under the mattress protector is a good idea for children’s beds.

Choose a supportive foundation

The foundation also plays an important role in ensuring a mattress will last as long as possible. If the base does not provide adequate support, it can cause the mattress to sag. Sealy provides foundations which are designed to correctly support it’s mattresses, however if you are going to use a non-Sealy foundation, you will want to ensure it is in good working condition. Read more about slat foundations positioninghere.

Rotate it properly

Lastly, Sealy’s mattresses are one-sided which means they can not be flipped. However, they should be rotated head-to-toe periodically. Body indentations are normal after some time, so rotating the mattress will prolong the support and comfort it can provide.

Sealy mattresses are built to last

When you make the decision to buy a Sealy mattress, you can rest assured that it is built just for you and is made to last. Thanks to the Sealy Guarantee, you will be able to use your mattress for at least ten years – and if cared for properly, it will probably last much longer.

Mattress Warranty Guide
What You Need to Know

First, know that a 25-year mattress warranty does NOT mean that your mattress will last 25 years, but mattress companies certainly want you to believe this.

While a warranty can be a gesture of good faith on the part of the manufacturer, and an indication that the company stands behind its products, you’ll want to understand what your warranty can and cannot do for you. And there are several “gotcha” scenarios where you might inadvertently void your own warranty.

Your new mattress will probably be between 10 and 25 years in length for most manufacturers and some offer a “lifetime” warranty.

Also know that many of those super-long warranties are pro-rated after 5 or 10 years, meaning that a fee can be subtracted for the amount of time the mattress was used, in which case the warranty may not cover the full purchase price or replacement value of the mattress.

Problems Covered by a Mattress Warranty

While a long warranty might sound impressive, warranties are only designed to cover defects and construction flaws like broken springs and extreme breakdown of mattress materials. Keep in mind that true defects will likely become apparent in the first year of ownership.

Body impressions and sagging

If you’ve read some consumer-written mattress reviews, sagging and body impressions are THE biggest mattress complaint. You’ve probably been on an old mattress at some point and noticed yourself rolling into a sunken spot. The cause for this is compression of the top couple of layers of a mattress to the point where the mattress fails to come back to shape, leaving body impressions, generally where the heaviest parts of your body contact the bed.

Manufacturer warranties differ greatly by how deep a body impression must be before it triggers a warranty claim. The industry standard for innerspring mattresses is 1.5” while memory foam is typically 3/4," but there’s a lot of variation from brand to brand. And manufacturers measure body impressions in a very specific way. With no one in the bed, a string is stretched across the bed. Then the distance from the string and the lowest point of the bed is measured. The problem? You can feel the ‘sinkhole’ even if it isn’t deep enough to be measured in that specific way, so it’s worthwhile to consider buying from a company that has a body impression warranty of an inch or less. You’ll find that information within the warranty info.

Some mattresses have better than average body-indentation warranties. Examples include the King Koil World Extended Life bed (which is marketed to heavier and plus-size persons), which warrants body impressions of just ½”—that’s the best we’ve seen recently. Several have policies of ¾”, including Loom & Leaf, Spindle, Tuft & Needle, and Tempur-Pedic.

You can help prevent body impressions by rotating your mattress 180 degrees every 3 months. (Note that most mattresses cannot be flipped; check if your particular model is "flippable" and flip periodically according to the manufacturer guidelines.)

Flaws in design, materials, and construction

As a general rule, most warranty failures are the types of problems that will reveal themselves in the first few years of ownership. Examples include broken springs (on an innerspring mattress), poorly stitched seams that haven opened, broken zippers, and split/cracking foam. Be aware that in certain types of beds (like air beds, waterbeds, or beds that have remote controls or other electronics), the warranty for specific components might be shorter. Some warranties exclude the cover entirely or have a separate warranty for it.

What’s NOT Covered by a Warranty

Generally, only observable, measurable defects are covered by a mattress warranty. Some issues that are not covered include:

Changes in comfort

The fact is that all mattresses will change over time. Generally, they become softer over the years. Changes in firmness/softness are never covered by the warranty.

Loss of support

You might find over the years that a mattress is no longer reaching up to support your lumbar area, or you’re sinking in more deeply than you once did. That’s normal, and could be an indication that it might be time to replace your bed, but it’s not covered under the warranty.

Normal wear and tear

Handles can eventually break; trim or cording might become frayed, or the cover may show pilling or wear in certain spots. These are considered normal wear and tear and are typically not covered.

Warranty Gotchas

There are several ways you might accidentally void your own warranty, and they’re all spelled out in the mattress warranty. Most can be prevented, so it’s a great idea to read your warranty before you need it, and to take precautions. Mattress warranty claims can and do get rejected for these reasons:

The mattress is soiled or stained

Most manufacturers state they won’t honor the warranty if the mattress has stains–including sweat stains, spilled substances, etc.–even if the stains aren’t visible. We’ve even heard of warranty inspectors checking a mattress with a black light to find hidden stains. The solution? Get a mattress protector and use it from day one.

You didn’t use a supportive foundation/frame

The mattress must be supported properly in order to make a warranty claim. Check the owner’s manual or warranty for what types of foundations are required for your bed, as well as which are prohibited under the terms of your warranty. Check out our page on foundations.

You aren’t the original owner

Most warranties are not transferable. Especially those with “lifetime’ warranties are not valid if you aren’t the person who initially bought the mattress. The warranty applies only to the original owner, so be sure to save your receipts to prove ownership.

You didn’t buy it from an authorized seller

Think you’ve found a good deal on Overstock? Think again. If you purchase your bed from an unauthorized reseller, it will not be covered by the manufacturer’s warranty. (The retailer might offer a substitute warranty, but that’s not a given.)

You removed the tag that says “do not remove under penalty of law”

That tag (called a law label) really isn’t for you – it’s a guarantee by the manufacturer that all-new and sanitary materials were used in the mattress. It’s illegal for a new mattress to be sold without the tag. Once it’s in your home, you can remove it, but it’s a good idea to leave it on, as some warranties won’t be honored without it.

What Happens if I have a Warranty Claim?

In the event of a problem, the manufacturer will want to have the mattress inspected. Depending on the retailer, the store where you bought the mattress might help you coordinate the details of submitting your complaint to the manufacturer. Someone might come to your home to inspect the mattress, or arrange pickup. In both cases, be aware you may be on the hook for shipping or inspection fees. If your warranty claim is approved, those fees might be refunded.

If you do file a claim, document everything and keep copies of any submitted photographs or forms and note all important dates. Be sure to dig up your original receipt and be prepared to verify that the bed has been properly supported.

See our guide on Filing a Warranty Claim for more on what to do.
