A warranty of 10 years is one way that you can gauge the durability of a memory foam mattress and how much its manufacturer is willing to back up its product.
In judging a warranty, at least 5 years of that 10-year warranty should be non-prorated, meaning you will get 100% of the repair or replacement taken care of for the first 5 years of the warranty. A prorated warranty means that after a designated number of years, the manufacturer will pay a portion of the mattress replacement or repair. A 10-year warranty that has 5 years non-prorated and 5 years prorated means that for the first 5 years, you are covered 100%. For the second 5 years, you will pay a predetermined portion of the replacement or repair.
At Healthy Foundations, our Healthy Foundations 10″ Memory Foam Mattress has an unheard of non-prorated 10-year warranty!
For any memory foam mattress warranty, make sure you read all the details and fine print and stay away from any memory foam mattress that has less than a 20-year warranty.
