Density is the easiest way to measure the lifespan of a memory foam mattress. The highest PCF foam (per cubic foot) stays the longest whereas low-density mattresses reduce the density and durability of the product.

The same applies to medium-density foams. High-density mattresses are costlier due to more layers and extra longevity of the product. However, if you are looking for durability, this is the one to look for.

3. ILD

ILD stands for Indentation Load Deflection. It is often referred to as IFD (Indentation Force Deflection) as well. In this process, a small test is conducted by pressing the mattress through a machine to check the foam’s firmness.

It is a standard test that is generally conducted for all types of memory foam mattresses.

Mattresses that have undergone the ILD test let you understand the feel and performance of the mattress along with the durability.

Based on the lifespan of the mattress, the manufacturing company offers a warranty. A warranty period helps you understand the average life of a mattress.

Companies that announce a lifetime warranty on their memory foam mattresses mean that you can relax on them for at least 20 to 25 years with comfort.

The process has to be repeated for a year. You will also find good quality mattresses that do not require rotating at all.

  1. You are right about a mattress being an important decision! You spend roughly 1/3 of your life on that thing. Memory foam mattresses are great and durable, but not for everyone. We got one and now regret it. It’s comfortable and has lasted for several years, but it doesn’t offer the back support we were hoping for. Now I wish we had spent more time in the store, testing different models. Don’t let the price tag fool you!

    Whether you go with box springs or memory foam or a hybrid, be sure to test a mattress out. Rest in it for as long as the store will let you before committing to one. And if you’re a couple, both of you should get in there for a test rest. You may disagree on everything and end up getting a model that lets you individually adjust each side’s firmness.

    Do you sleep on a memory foam mattress? Do you find it a major upgrade compared to your last mattress?

      Yes I do sleep on memory foam mattresses AND also a pillow. It took me long to “make the switch’ but I am super happy I did and from now on, I’ll only be buying memory foam for comfort and a good rest.

      Money well spent definitely! 🙂 I can’t reccommend memory foam enough!
