Many mattress companies offer risk free trials and money back guarantees, but a warranty gives you protection against defects long after these assurances have expired. A warranty offers reassurance that if you discover a problem with your mattress, it will be repaired, replaced, or refunded.

Warranties will vary by manufacturer in details. Details include proration, sagging threshold, and length of the warranty. A 10 year warranty is standard for mattresses, though some may offer warranties as long as 15 or 20 years.

Mattress warranties offer peace of mind, but like any warranty, they come with a lot of requirements. There are many ways to accidentally void your warranty. There are also many issues that will not be covered under your warranty. In this guide, you’ll learn about these details and everything else you need to know about mattress warranties before you make a purchase.

What’s Covered in a Mattress Warranty?

Mattress warranties cover physical defects. They must be defects in the manufacturing or materials. Mattress companies will typically require an inspection and return of your old mattress before they repair or replace your mattress. Your mattress claim is likely to be covered if if you have one of these issues and your mattress warranty is still valid.

  • Sagging: Sagging is a common complaint as mattresses age. This issue can interfere with comfort and support. Warranties typically cover sagging after it reaches a certain depth.
  • Torn handles: Handles that have ripped out or broken will be fixed under warranty.
  • Seam defects: Mattress warranties will cover seams that are coming apart or broken.
  • Broken or defective coils: Mattress warranties will typically cover coils that are broken, loose, or have popped out through the fabric.
  • Broken box springs or foundations: Box springs are often replaced under warranty for many issues, including frame splits, loose beams, and broken wires.
  • Squeaks or rattles: Some mattress warranties cover unusual noises, such as squeaks or rattles. But before you make a claim, be sure it’s your mattress and not your bed frame or floor.

What’s Not Covered in a Mattress Warranty?

Anything not specifically listed in your mattress warranty will not be covered. This includes no longer liking the mattress, normal wear and tear, damage from misuse, and problems with fabric.

  • Dissatisfaction with the mattress: Most mattress companies will not accept warranty claims for customers who decide they no longer like a mattress.
  • Normal wear: Mattresses that become worn over the years from regular use will not be replaced under warranty unless they show signs of faulty workmanship or materials.
  • Damage from using an improper frame: Most mattress manufacturers sell their mattresses with a frame designed for their products. Using inadequate support for your mattress and then claiming damage under warranty will not work.
  • Stains: Mattress owners are expected to maintain the cleanliness of their products.
  • Fabric: Across the board, mattress fabric is a no go for mattress warranties.
  • Damage from moving: Border wires, fabric, andother pieces of the mattress can be damaged during moving, especially if the mattress is bent. This damage is not covered under warranty.
  • Minor sagging or body indentations: Until mattress sagging reaches a certain measurable threshold, mattress companies will not repair or replace the product under warranty. This threshold is usually between 3/4 and 1 1/2 inches.

Things That Void a Mattress Warranty

Even if you have a valid manufacturing or materials defect on your mattress, your warranty may not cover it. If there’s evidence of issues that void your warranty, even the most obvious claim will be thrown out. Usually, mattress companies look for signs of abuse and misuse when determining whether your warranty is still valid or void.

  • Stains: Practically every mattress company has a problem with stains, and they will not accept claims on stained mattresses, no matter how small. A protective mattress cover is recommended to avoid stains and save your warranty.
  • Abuse: Bending, staining, burns, cuts, or any damage that is obviously not from simply sleeping on the bed will cause your warranty claim to be denied. This includes jumping on the bed.
  • Improper support: Mattress manufacturers expect that you’ll use appropriate support for your mattress. If you don’t, you could be out of luck with your warranty, as this can lead to increased sagging. Manufacturers will also require you to follow a rotation schedule if your mattress needs to be flipped or rotated regularly.
  • Removing the law tags: Customers won’t get arrested for removing the law tag from your mattress, but it might cause a problem with your warranty. Often, an intact law tag is required for warranty claims.

Warranty Length and Mattress Lifespan

A long warranty length can be reassuring. But don’t assume that the warranty length offered by a mattress company is a promise that the mattress will last that long. Often, mattresses do not last as long as their warranties.

Typically, mattresses do not retain the same level of comfort, support, and usefulness for all of the years of the warranty. Normal wear is not covered even though defects in manufacturing or materials are. That means if your 20 year warrantied mattress becomes uncomfortable on year eight, you’re out of luck on a warranty replacement.

Pro-rated vs. Non-prorated Warranties

Prorated and non-prorated warranties are very different. Under a valid non-prorated warranty, a mattress will be replaced, repaired, or refunded 100% no matter how long you’ve owned it. With a prorated warranty, you’ll simply be reimbursed for the years you have left on your warranty.

A non-prorated warranty is clearly more valuable than a prorated one. This offers 100% protection as long as your mattress is still under warranty. You won’t have to worry about paying for a new mattress if there’s a problem with your existing one.

Some manufacturers will offer a mix of non-prorated and prorated warranties. Non-prorated coverage and prorated coverage may make up a 10 year mattress warranty.

How to File a Warranty Claim

Mattress warranty claims usually take four to six weeks or longer to complete. Usually, the warranty only covers the product. It does not include inspection fees or transportation costs associated with the warranty.

Most manufacturers require customers to contact retailers about warranty claims first. There are exceptions if you’re working with a direct to consumer mattress company or the retailer has gone out of business. In that case, you’ll deal directly with the manufacturer for your warranty claim.

To start your warranty claim, you’ll need to contact your retailer or manufacturer and fill out a claim form. Customers may be required to provide an original sales receipt and law tag along with your warranty claim form.

Customers will be contacted and pay for an inspection. This fee usually ranges from $25 to $50. Manufacturers will ask customers to send in the product if the warranty claim is deemed valid. Customers will be responsible for shipping in most cases, which is usually between $70 to $100.

Unfortunately, many mattress warranty claims are denied. There are simply more issues that void or are not covered under warranty than there are valid covered issues. Stains, even very small ones, are the most common reason why mattress warranties are denied.

Tips for Making the Most of Your Mattress Warranty

When you’re investing in a new mattress, the reassurance of a valid warranty is important. Follow these tips to make sure you’re choosing a mattress warranty you can trust and maintaining your mattress. That way, any claims you may have to make in the future will be valid.

  • Protect your mattress: Manufacturers recommend a protective mattress cover. Look for a waterproof cover. Even better: one that will lock out bedbugs, mold, and other issues that may void your warranty.
  • Never abuse your mattress: Burns, cuts, or tears will not be covered. These signs of abuse will automatically void your warranty. The most common abuse: bending mattresses during moves. Like the others, this damage is not covered under warranty. If you move, take care to keep your mattress safe during transportation.
  • Use adequate support for your mattress: Mattress companies will not cover products that have sagged if you haven’t supported them properly. Follow your manufacturer’s directions on acceptable support for your mattress model. Often, it’s best to simply buy the right support or foundation from the manufacturer at the same time as your mattress.
  • Go with a mattress company you can trust: Many new mattress companies are popping up online. We don’t yet know how well they honor their mattress warranty claims. Even established mattress companies can have warranty issues. They may have a long history of denying claims that customers believe are valid. And of course, any warranty from a mattress company that goes out of business will be worthless. Look for a company that you trust and expect to be around for a long time. Before making your choice on a mattress company, do some research on the reputation and trustworthiness of the business using resources including the Better Business Bureau, Consumer Reports, and Sleep Like the Dead.
