Offered by most mattress manufacturers, a warranty helps protect you from defects in your new mattress. It is an indication that the manufacturer is willing to fix certain flaws in the design, materials, and construction of the mattress for a certain period of time. However, a warranty is not a guarantee of durability, nor does it offer protection against general deterioration in comfort or normal wear and tear.
Most high-quality mattress manufacturers offer warranties lasting between 10 and 20 years. But since warranties do not protect against the general loss of comfort that happens naturally over time, warranty length does not necessarily correlate with mattress durability. Put another way, you should not assume that the length of the warranty indicates how long the mattress will last before its comfort and/or support begins to deteriorate.
A mattress warranty typically covers flaws in the design, materials, and construction of the mattress. As a general rule, warranty failures are the types of problems that tend to reveal themselves in the first few years after you purchase your new mattress. In a traditional innerspring mattress, common examples include broken springs or open seams. For beds with more components (such as air beds, adjustable beds, or waterbeds), individual components such as motors and remote controls may be addressed separately. It is best to check your warranty policy in advance to see whether any specific components are excluded or covered differently from the main warranty terms.
Problems with the mattress that do not fall into the category of defects in the manufacturing or materials are generally not covered by the manufacturer’s warranty. Unfortunately, it can often be difficult to distinguish a quality issue in your mattress from your preferences. If your mattress feels uncomfortable because it’s too hard or too soft, those aren’t considered defects and won’t be covered by a warranty.
If you think you have a warranty claim, your first step should be to consult your original receipt. Depending on the retailer, the store where you bought the mattress may be able to help you submit your complaint to the manufacturer. If your problem is covered by the warranty, the manufacturer will likely want to have the mattress inspected, which will involve someone coming out to examine the condition of the mattress. Note that mattress warranties are known for their fine print, and it is generally difficult to make a successful claim.
Some warranties become void under certain conditions, such as if the mattress is soiled, if certain tags are removed, if the owner does not have the original receipt and/or warranty forms, or if it the mattress is used with an unauthorized or faulty foundation or frame. Be sure to check your warranty to understand any such limitations.
If your problem is covered by the warranty, your warranty may be prorated, meaning that a fee can be subtracted for the amount of time the mattress was used. In this case, the warranty may not cover the full purchase price or replacement cost of the mattress.
