These days, it's difficult to prevail in a mattress warranty claim. The deck is stacked against the consumer, when it comes to this.
Stains on the mattress, of any kind, will automatically void the warranty.
We would prefer that you use a waterproof mattress protector to start with, so that you don't have stains to deal with.
We carry the best we've ever come across and use it at home. Made by Danican, it sleeps cool, won't shrink, and fits easily to any mattress up to 18" thick.
However, we have information for you on how to clean those stains, so that they won't stop you from having your mattress exchanged.
We have not tested these, at home, but we were told that they work, it will help level the playing field between you and the manufacturer.
