How Your Mattress Warranty Works

One of the most common questions I’ve been asked about mattress warranties is, “What exactly is a mattress warranty for?”

Intuitively, you would think, “It’s a mattress.  What could possibly go wrong?”

And the answer is…not a whole lot, really.  But, once in a blue moon something does go wrong.  That’s where the warranty comes in.

Before I show you what a mattress warranty does cover, I’ll first tell you what they don’t cover.

  • A mattress warranty does not guarantee that you’ll “like” the mattress…
  • It does not guarantee that you’ll still think it’s comfortable 10 years later…
  • It does not cover damage caused by jumping on the mattress, or damage caused by moving…
  • Size discrepancies of up to plus or minus 1 inch
A warranty is in place to cover manufacturing defects, or if something structurally goes wrong during normal use while using a proper foundation and bed frame with a center support.

For example, you get a new mattress and a month later, it’s sinking 3 inches in the middle of the bed.  You’re using the matching foundation and you have a proper bed frame, but for some reason the mattress has collapsed.  In this situation, the mattress is most likely to be determined to be defective, and the manufacturer would typically replace it.

Or, lets say after having your mattress for a year, a spring pops out.  (Highly unlikely…but anything is possible.)  They would replace it.

So, typical issues covered include:

  • Seams coming apart
  • Sagging greater than the manufacturers allowable amount
  • Structural failure (ie, a coil malfunctions or pops out of the bed)

Non-Prorated vs. Prorated Warranties

Mattress warranties are typically a combination of a non-prorated and prorated terms.  So, in a hypothetical 15-year limited warranty example, the first 10 years might be non-prorated, and the next 5 years prorated.  During the first 10 years, you wouldn’t have to pay anything out of pocket if your mattress were defective.  After the first 10 years, you would have to pay a percentage to have it replaced any time during the next 5 years, with the percentage increasing each additional year until year 15.

One thing to keep in mind is that the way mattress warranties work, is that if the mattress gets stained or soiled in any way, the warranty is voided.  So, if you spill a cup of coffee on your bed and it stains your mattress, the warranty is now voided.  This is because of health issues related to bedding and the way the laws work.  It’s completely ridiculous, but it’s how the manufacturers have been able to set them up.

This is why it’s critical that you protect your mattress from the very beginning with a stain-proof mattress protector.  A good protector will not only protect your mattress warranty, but it will prevent mold, mildew, dust mites and other allergens.  Read my article on protecting your mattress here.

What You Need To Know If You File A Warranty Claim

Expect the process to be fairly slow, somewhere between 4 to 6 weeks to get it all sorted out.  Most of the time they’ll have an independent inspection company come out to your house to take measurements of your mattress.

They are unbiased, they do not favor the manufacturer or the customer, they simply follow the warranty guidelines.  They have special tools that they use to measure impressions in the mattress, and usually you’ll have to schedule a date and time for them to come out to your place.

You may have to pay for this service out of pocket and that fee varies, but that fee is often refunded back to you if your mattress is determined to be defective.  Of course, this depends on what brand you purchased, where you purchased it from, etc, so I suggest you find out in advance before making a purchase.

If you purchased a mattress online, you may be responsible for shipping fees.


  • Warranty issues with mattresses are fairly rare
  • Make sure you protect your warranty by using a mattress protector
  • Always make sure your mattress is placed on a proper foundation with a center support that reaches the ground

  • Great information for shoppers Sean. We’ll post this on Sleep Geek and recommend that RSAs print this blog post and offer it to customers. This industry needs transparency and clear information about warranties is a big piece of that puzzle.

  • These warranties are often legally unenforceable. My law firm is currently assembling a class action against mattress companies that hide behind warranties of legal questionability. Every case is different so we can’t always guarantee success, but we have achieved some excellent results in the past. You can check out for more info.
