That's a whole different level of shadiness I've found out with only a bit of digging... Most have partially pro-rated warranties. So, if it says 25 years, it might have a 15 year pro-rated portion, so if there is a problem after 12 years, only a portion of the cost is covered.
Not to mention all the fine print and exclusions. Any kind of stain/surface wear, not covered. Using it on a slat type bed, instead of a box spring, not covered. Didn't follow the instructions and have it flipped every 6 months and cleaned every year, not covered. Sagging, but less than the 2.5in minimum depth, not covered... can't find the original bill 10 years later, not covered.
Even if it is covered, apparently you need to pay for pickup/shipping, which isn't easy on a giant mattress....
...warranties are the red herring in a product like this. They know nobody ever claims a warranty, so it's pretty useless. More marketing nonsense!
