Durfi mattresses include a 10-year guarantee. 
Durfi offers a ten-year limited warranty for mattresses up to 84 x 84 x 10 inches.
If you order a custom mattress larger than this size, the warranty will only be guaranteed for five years.
The warranty covers manufacturing faults such as dents, sagging, indentation,  or stitching coming off. 
However, the warranty is not covered by accidental damage you or another person may have caused.
We highly recommend purchasing a mattress protector to protect your mattress and its warranty.
