Mattress King Warranty Information

Sometimes, even the highest quality products may fail, show early signs of wear, or have a manufacturing defect, after all they’re all hand made. At Mattress King, we stand by our commitment to help you get your best night’s sleep. If something goes wrong with a product you purchased from us, we’re here to help guide you through the warranty process. It’s important to know that your mattress warranty is covered by the manufacturer, not by Mattress King, and the process may differ depending on the product type and brand. Because we’re in the business of giving you peace of mind, we’ve set up a list of things to help you determine if there’s a defect that is covered and to help facilitate the process.

What is covered by the Manufacturer’s Warranty?

A warranty protects your purchase from defects in manufacturing – not from damage caused by use, or by normal wear and tear. You can find specific details on what is and isn’t covered on your manufacturer’s warranty card and by this list we’ve provided below.

These warranties are non-transferable and only cover the original purchaser/current owner and must have been purchased directly from an authorized Mattress King location.

Manufacturer warranties are limited to material defects resulting from defective materials or workmanship in the product you have purchased.

Specifically, these warranties cover the following defects, provided that they arise or appear in circumstances in which you have handled, maintained, and used the product only for its intended purpose and have not subjected it to conditions likely to cause deterioration or damage beyond normal wear:

  • Deterioration causing the mattress to have a visible indentation greater than 1.5 inches that is not associated with an indentation or sag which results from use of an improper or unsupportive foundation or frame without adequate center support . Normal wear requires that a mattress be continuously supported by a matching foundation or adjustable bed base with a proper bed frame with center support legs sufficient to support the collective weight of the mattress and foundation.
  • Any physical flaw in the mattress that causes the foam material to split or crack, despite normal usage and proper handling.
  • Coil or wires that are loose or broken, coils or wires that protrude or rip through the mattress fabric.

 What is not covered by this Warranty?

  • A normal increase in softness of the foam pressure-relieving material which does not affect the pressure-relieving qualities of the mattress
  • Comfort preference
  • Physical abuse or damage to the structure and/or cover material, including but not limited to, burns, cuts, tears, liquid damage, or stains; provided, that the defect is caused by such abuse or damage
  • Body indentations: Less than minimum impressions as defined in “Warranty Coverage” above
  • Mattress damage due to an inappropriate foundation or inadequate center support
  • Normal Wear and Tear (Body impressions are a natural occurrence and are to be expected. This is due to the upholstery layers conforming to your body and do not necessarily indicate a structural defect.)

What will void my Warranty?

  • Stains and soiling, so be sure to use a mattress protector
  • Improper or unsupportive foundation; Mattresses need to be on a perfectly level platform/foundation
  • Frame without adequate center support; A frame or bed frame should have at least 5 legs supporting slates or steel crossbars
  • Missing law tag (law tag will have date of manufacturer and warranty code)

Your responsibilities

In the event of a defect that is covered under the manufacturer’s warranty guidelines, they will need the following from the customer:

  • Pictures highlighting the visual indention in the mattress; This can be easily done by pulling a string across tightly or laying a straight edge on the top surface of the mattress showing the indention that is greater than 1.5 inches
  • Picture showing that there is at least 5 legs supporting the slats or steel crossbars
  • Picture showing that the top surface is free of stains and or soiling

To submit warranty pictures, please send them to: support@imagoodking.com or text pictures to our customer service team at 405-609-9398.

For the most breathable, easy protection, we recommend using the Malouf mattress protector. Purchasing the protector will allow your investment to last the longest possible time. Putting a fitted sheet on top of your mattress will keep it clean if you aren’t interested in the protector, but it won’t prevent spills or leaks from seeping into the foam.


Whether you have purchased a Traditional two-sided mattress, or a single-sided mattress, proper rotation is critical. We recommend rotating a new mattress head to foot every 2 weeks for the first 2 months, and once every month thereafter. If a mattress is double sided add flipping the mattress into this rotation to increase its comfort life and longevity. (Note: for king size mattress rotate quarter turns if no one sleeps in the center of the bed). Body impressions due to lack of rotation will not be covered by any warranty as it is a part of proper maintenance. Keep all moisture away from the mattress. Moisture combined dead skin will make the fabric layers compress quickly, greatly reducing the life of your mattress. Purchasing a Malouf mattress protector is a simple way to insure moisture and dead skin is kept out of the mattress and they also protect against stains.


DO rotate your mattress as recommended.

DO use an appropriate frame and center support on full, queen, and king-size sets to ensure validation of your warranty.

DO let your new sleep set “air” upon removal from its plastic packaging and dispose of all plastic packaging as soon as possible.

DO keep your bedding clean and use a mattress protector, especially if children use the bed.  DO replace the foundation when purchasing a new mattress to provide the proper support for  your new mattress.

DO carry your mattress upright. It is easier to handle and less likely to damage the mattress.  DON’T expose to fire or place near flame. This mattress is not flame or fireproof and can ignite  and/or burn if exposed to fire or open flame. When ignited, some bedding materials can burn and emit smoke and hazardous gases.

DON’T remove the law tag at the end or your mattress, as this has the identification needed to  establish your warranty rights.

DON’T bend your mattress under any circumstances. Such treatment may damage the innerspring unit.

DON’T place a board between your mattress and foundation. It will diminish the longevity and  performance of your sleep set.

DON’T stand or jump on your mattress. Abuse will void all warranty

DON’T use the edge of the mattress as a chair. This will not be covered in the warranty

DON’T get your mattress wet, this may cause the upholstery layers to compress.

DON’T stain your mattress, this will void the warranty.

DON’T place a new mattress on an old box spring without checking to see if it is warped. Placing a new mattress on a warped box spring will make your new mattress conform to it and will void all warranty.
