Are you shopping for a new mattress? Here’s everything you need to know about mattress warranties

Buying a mattress is a long-term purchase and getting one with a warranty is ideal. A warranty saves you from the cost of repairing or replacing your mattress within a specified period.

A warranty is a written guarantee from a manufacturer that promises you to fix or replace an item within a particular period after purchase. You should consider a warranty’s period, terms, coverage, and type before purchasing a mattress.  Most mattress warranties are valid for 5, 10, 15, 20 years. There are two types of mattress warranties. They differ as shown below.

Written Warranty Implied Warranty
A manufacturer or retailer gives a written guarantee that they will repair or replace a faulty mattress. The law doesn’t require mattress companies to issue written warranties.


All the states in the U.S. have legal warranty stipulations manufacturers and sellers should follow.
Brands and sellers stipulate varying conditions in their warranties. You must meet specified conditions. A warranty of merchantability ensures an item performs all its designated and essential functions to meet a customer’s expectations. A warranty of fitness also guarantees you can use an item for any or all specific purposes you agree on with the seller

What a mattress warranty covers

Mattress companies recognize the following as defects that are subject to a warranty;

  • Coils that bend, break, and burst on the side of the mattress
  • Undone seams
  • Sagging or sinking
  • Irregular bunching at the corners, especially in foam mattresses

Why is a mattress warranty important?

Mattress warranties protect you from a faulty mattress. A warranty guarantees that a mattress retailer will replace and repair flaws, defects, and faulty parts in your mattress at no extra cost.

Filing a warranty claim

If your mattress doesn’t meet the conditions stipulated in your warranty you can file a warranty claim. However, they are certain costs you may incur during the claiming process. Once you file a claim, the following steps may happen;

  1. The mattress company will inspect and evaluate your mattress to ascertain your claim. If your concerns are valid, the company will incur the cost of the inspection. In most cases, many owners foot this cost and it ranges between $40 and $60. A company may also mail a self-inspection kit that costs $30 to $50.
  2. If you file your claim during the specified period, you will be responsible for fraction of the repair costs as stipulated in the warranty.
  3. If you purchased a defective mattress, you need to pay for the shipping costs of a new mattress. Shipping fees range between $80 to $100. Some mattress sellers and companies may discount this service.

What voids your mattress warranty?

The following factors will void your mattress’ warranty;

  • Stains corrode foam and break the structural integrity of your mattress. Companies can’t remove and legally store mattresses with stains especially when they’re permanent. Therefore, non-toxic liquids like water, coffee, and water can void your warranty. Use products such as this list of best mattress toppers to protect your mattress from stains.
  • An old, damaged, misshapen bed or box spring destroys the integrity of your mattress. A warranty includes bed specifications you must follow.
  • Mattresses are compressed for shipping purposes and warranties require you to unpack them immediately. Failing to remove their packaging 2 to 4 weeks after purchase damages their integrity.
  • Selling or gifting the mattress to someone else. Warranties don’t extend to a secondary owner.
  • Removing the law tag attached to the back of a mattress. It instructs you not to remove it under a penalty of law and its proof of purchase.
  • Failing to follow a mattress rotation schedule. Manufacturers expect you to flip your mattress occasionally to rejuvenate its structure to avoid premature sagging.


A mattress warranty is an excellent option for your long-term purchase. It guarantees a reseller will repair or replace your mattress in case of damage. However, a warranty is only valid when you meet a seller’s conditions.
