Mattresses are a major investment, and consumers have many choices when choosing to buy a mattress. Before purchasing one, however, it’s important to ask a few key questions regarding mattress warranties and what you should be able to expect as far as performance, quality, and refunds or replacements.

Before buying a mattress, find out:

  • Who provides the best structural support and foundation?
  • Who has the best hassle-free customer support?
  • Do mattress companies offer no-questions-asked refunds?
  • Who offers the longest warranties, and what is covered in each type of warranty?
  • What are the differences between prorated and non-prorated warranties, and which one is better?
  • How do you file a mattress warranty claim, and what voids or nullifies a mattress warranty?

This guide will answer these questions and more so consumers looking for a mattress for personal use can learn what kind of warranty they’re getting and where to get the best warranty from.

What is a warranty, and why is it important?

Warranties were developed to remove doubt from the minds of consumers. A warranty is a guarantee that a business’s product will act or perform in a certain way, for a certain period of time, under certain conditions. This allows consumers to purchase products without the fear that they may malfunction or not meet promised performance specs, on the manufacturer’s commitment that the product will be repaired or replaced should any issues arise.

When it comes to mattress warranties, this is generally what you can expect:

  • That your mattress will be replaced for you at no charge if something goes wrong that is not your fault (basically, if something goes wrong as a result of structural or production shortcomings).
  • That you can claim this replacement for a specific amount of time after your purchase has been completed.
  • That this commitment is being given to you from the manufacturer of the mattress itself, not the point of sale or vendor from whom you purchased the mattress.

Having these kinds of warranties are important because:

  • Mattresses are expensive! So it is important that you get a product worth your money, and that your investment is protected.
  • If something goes wrong that is not your fault, you aren’t set back the entire cost of the mattress. You are instead given a replacement on the manufacturer’s dime.

As mentioned above, warranties are used to assure customers of quality and give consumers peace of mind.

What is covered in a mattress warranty?

Mattress warranties only cover production or manufacturing defects. For example, your warranty would be valid and you would be covered if something were to go wrong with the structure of your mattress as a result of normal, proper use in a way intended by the manufacturer (like using the mattress for its intended purposes while having a firm foundation with adequate support).

Production and manufacturing defects include:

1. Anything wrong with the structure of the mattress (if it is misshapen, has missing stitches, or if there are size inconsistencies greater than an inch)

2. Excessive sagging (usually defined as being between ¾ and 1 ½ inches of sagging in the absence of any pressure being applied)

3. Unexpected damage, such as a spring popping out, or edges tearing where they shouldn’t

What’s NOT covered in a mattress warranty?

As mentioned above, mattress warranties cover production and manufacturing defects, because these are things that can be directly linked to shortcomings that the manufacturer is directly responsible for. This means that virtually everything else is NOT covered by mattress warranties, including:

  • Normal wear and tear
    • This means scuffing, deterioration, blemishes, corner threads coming out, or handles becoming slightly loose as a result of using the mattress for its intended purpose of being slept on
    • While normal wear and tear that happens as a result of normal, regular use of the mattress is not covered, other defects or shortcomings such as handles that are completely torn, coils that stick out, and squeaking ARE covered by most warranties
  • Sagging is covered by most manufacturers during the warranty period, with any sagging greater than 1 ½ inches covered by virtually every manufacturer
  • Damage such as bent border wires or torn mattress fabric that can result from either the transportation of the mattress, using an improper frame, or rough use such as jumping on the mattress
  • You are not given a guarantee that you will continue to like your mattress with the passage of time as much as the day you bought it
  • Bedding that is sold “as is” or floor models that are sold with any type of pre-existing damage
  • Body indentations less than 1 ½ inches (in some cases no more than .75 inches)
  • Unexpected lumpiness
  • The mattress exerting pressure on your body where you feel there shouldn’t be any
  • Inadequate support according to your personal preference

The last three reasons are directly responsible for decreased satisfaction over time as a result of regular use, and are why most people change their mattresses. Disputes occur because people think these should be covered under warranty, but they are not.

What voids a warranty

Mattress manufacturers offer warranties to give you peace of mind before you buy a mattress from them, but they still draw the line somewhere. Here are a few things you should avoid doing so that your mattress remains under warranty.

So while removal of the tag is illegal for manufacturers and sellers, consumers can, in fact, remove the tag. However, the reason why removing it will void your warranty is because the tag ensures that the manufacturer can trace specific products, and without a tag, there is no way to tell two different mattresses apart.

  • Stains will void your warranty. Liquids such as coffee or carbonated sodas can cause mattress foam to deteriorate or disintegrate faster than normal. Also, drink stains are very unhygienic, meaning no one would want to buy such a product should it be returned by you to the manufacturer. Waterproof mattress protectors (such as these ones) are a great idea, and they help prevent not just stains caused by outright spills but even perspiration stains that develop slowly over time.
  • Improper support such as a non-matching or old box-spring, or a missing support bar will void your warranty. Putting your mattress directly on the floor will also void your warranty. Check your warranty for mattress-specific sizes that you should use, as well as for other useful support specs and recommendations.

Warranty length and mattress lifespan

You can expect, as a rule, that mattresses with longer warranties will last longer, and that mattresses with shorter warranties will not last as long as their higher-quality counterparts. However, for both high-end or long warranty mattresses, as well as for lower-end or short warranty mattresses, the actual useful life of your mattress will be LESS than the length of the warranty.

Different manufacturers have different data sets that provide this information, and the numbers are different for waterbeds, latex mattresses, futons, memory foam mattresses, and air mattresses. However, according to this 2008 study (summarized for you here), as well as consumer reviews, you can expect the following:

  • A mattress that has a warranty of 5 years is generally only usable for 4 years
  • A mattress with a warranty of 10 years is only usable for about 8
  • Most high-end mattresses (in the $3,500+ range) are usable for a full decade with proper care

When trying to calculate the life of a mattress, first select your preferred price point and scale up or down the estimates above while keeping in mind the wear and tear that you expect to put your mattress through as part of your normal usage routine.

Prorated vs. non-prorated warranties

Prorated warranty

With a prorated warranty:

  • You pay a certain percentage to have your mattress repaired or replaced
  • The percentage generally goes up over the period of a predetermined number of years
  • The older the mattress gets, the more easily it becomes damaged, so your percentage of repair and/or replacement costs goes up

The pros of a prorated warranty are:

  • Since you have some control over the use of your mattress, you can effectively ensure your mattress suffers less damage with time
  • This means repair costs will be less, and you in turn pay less at the end of the day to have your mattress repaired

The cons of a prorated warranty are:

  • You are guaranteed to have to pay something whenever you want to repair or replace your mattress

Non-prorated warranty

With a non-prorated warranty:

  • You are covered for the cost of repair or replacement for a predetermined number of years, meaning you pay nothing for repair and/or replacement during the warranty period

The pros of a non-prorated warranty are:

  • You don’t have to pay anything if you need to have your mattress repaired or replaced

The cons of a non-prorated warranty are:

  • Having your mattress transported, repaired, and brought back, which is not only a nuisance but can also be costly. Prorated warranties also have this cost, but manufacturers may be less likely to split the cost with a non-prorated warranty. Check warranty information specific to your mattress of choice for details.

Mattress manufacturers generally use a combination of both types of warranty. You can expect, for example, a non-prorated warranty to cover your mattress for the first few years, after which you are covered by a prorated warranty for the next few years until the entire warranty period is over.

How to file a warranty claim

To file a warranty claim, you’ll need to contact the customer support department of the manufacturer to issue a claim and submit either photo proof, proof of purchase, or both. It could take between one month and a month and a half to get things rolling and to have an inspection team visit your home to determine whether or not your case is sound, but otherwise the process is generally fair and straightforward.

Although you may have to pay for the inspection team’s visit yourself (as well as transportation and delivery charges), customers are often refunded if their claim goes through and their mattress is in fact determined to have been defective.

The best preventive measure is always a proactive, safety-first approach to mattress care, so be sure to use a mattress protector and be careful with liquids around your mattress. Don’t use your mattress for anything other than sleeping on or lying down on. By doing this you can save a lot of headache and heartache when it comes to voided warranties and replacement and repair costs.

Mattress warranty advice and tips

  • Because mattresses are so costly, and because having a comfortable mattress is directly linked to comfort and well-being, it is important to protect your mattress.
  • Warranties help you get the most out of your mattress, so be careful not to void your warranty. Always follow the manufacturer’s use and care instructions.
  • Depending on the size of the mattress you purchase, you will need a frame and mattress support of specific sizes. Your mattress will come with a specs sheet outlining what size and type of support your mattress requires, so be sure to purchase one within the required range.
  • It’s always a good idea to look at customer reviews before making a purchase. Reviews are a great source of first-hand usage reports and personal recommendations made by thousands of consumers just like yourself.

Additional resources for mattress warranties

There are a number of independent organizations that are dedicated to collecting various types of mattress data. Some of these organizations also conduct quality checks and tests, and they publish their findings several times a year.

  • At Consumer Reports, you can find useful customer reviews, mattress buying tips, and convenient grading scales for mattress comparisons. The site even debunks several mattress myths for you!
  • The International Sleep Products Association (ISPA) is another great resource if you are looking for specific information on anything from mattress industry projections to historical data. Here you can find a lot of information on various mattress quality standards. The site provides details on the usable life of different bedding parts as well. The ISPA was established with the stated goal of encouraging people to invest in better bedding and to promote more awareness of the relationship between bedding and overall well-being.
  • If you want  to get a general idea of how established a certain manufacturer is, or how professionally they handle everything from warranty claims to customer service, try visiting the Better Business Bureau. A BBB review, as they are called, is basically a review of company licensing, consumer experiences, accreditations, and government actions relevant to that specific company. For example, BBB’s review of Tempur-Pedic International, Inc., can be seen here. Each review gives you everything from company contact info to accreditation level, customer reviews, and complaint information.
  • Finally, at, you can find interesting information on mattress management, how and where to recycle, new programs related to mattress parts and replacement, and laws pertaining to the purchase and disposal of different types of mattresses.
