Mattresses can and often do have their warranties voided due to the use of an improper foundation / frame and the presence of staining, soiling or fluid penetration.
Improper Foundation / Frame
An improper foundation / frame can result in premature wear and sagging of the mattress. Read your warranty’s foundation / frame guidelines and follow them to the letter. Mattress companies do not give leeway on this issue; your foundation / frame either meets their warranty guidelines or it doesn’t.
Staining, Soiling And Fluid Penetration
These can fully void a mattress warranty. Even if the staining, soiling or fluid penetration is not near a defective area, such as where sagging is located, the warranty will probably not cover the sagging.
Beware: Non-prorated vs Prorated Period
Many mattress owners realize too late that their warranty sounds more impressive than it actually is.
The whole story is that non-prorated coverage (coverage for which there is no cost to the owner to repair / replace the bed) often ends after just a few years. If something goes wrong with the airbed after this time, coverage is prorated which means the owner will often need to pay at least 20% of repair costs.
Therefore, make sure to read the fine print of a mattress warranty.
Normal Wear Not Covered
Mattresses are discarded for a variety of reasons, but the main reason not surprisingly is usually related to a loss of comfort and support that occurs through normal wear.
As is true for virtually all product warranties, normal wear is not covered under mattress warranties; only faulty workmanship / materials as defined by the manufacturer are covered. These defects are problems that can be objectively measured or observed
It Will Cost You
Making a warranty claim can be expensive to the mattress owner.
There can be a fee to have someone come to your home to inspect the condition of your mattress to determine if it is eligible for warranty coverage. If it is eligible, there will be a fee to take the defective mattress away and to ship a new or repaired mattress to you. Given the heavy weight of many mattresses today, this fee may be substantial.
In addition, depending on the age of the mattress and the warranty terms of peroration, you may have to pay a percentage of the replacement or repair costs.
The main complaint people have with their mattress is sagging – especially in regard to innerspring beds in general and to a lesser extent memory foam, latex and air mattresses.
Owner experience data suggests that even moderate sagging can and often does result in less comfort and support. It may also cause back pain, especially for side and stomach sleepers. As a result, mattress shoppers should pay special attention to how sagging issues are covered by the warranty. Most warranties will cover sagging only when the problem becomes severe enough, that is, when it reaches a certain depth.
