What factors you should consider while selecting memory foam mattress that lasts long?

We already discussed that memory foam mattresses are the most durable in the market. Let’s begin with the factors that influence memory foam mattresses’ lifespan.

1. The density of the mattress

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.

Here a quick chart for you to refer to check the durability of memory foam mattresses:

  • HD (High Density): More than 5 Per Cubic Foot
  • MD (Medium Density): Anywhere between 3.5 to 5 Per Cubic Foot
  • LD (Low Density): Less than 3.5 Per Cubic Foot

*Note: Low-Density mattresses break down sooner. You also need to remember that density is not related to the firmness of the mattress. High-density foams sustain their shape despite the softening with time.

2. Thickness and Layers

A mattress that is dense, thick, and firm has the best support. However, people often have this misconception that the thicker the mattress the longer its durability compared to the thinner one.

For instance, two mattresses of the same thickness and same height may differ in lifespan. It is due to a change in density.

You also need to understand how much body weight can a mattress hold. Select the thickness as well as layers respectively.

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.

4. Warranty

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.

Along with the warranty, comes a set of instructions to follow. Any after-care steps that are

Tips to extend the lifespan of a memory foam mattress

2. Rotating the Mattress

As you continue to use memory foam mattresses, these soften with time. If you want to stretch the life cycle of the mattress, some brands will ask you to rotate the mattress at least once a month.

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

Try checking out the double-sided or flippable mattresses as well. Such mattresses are manufactured with different firmness on either side. Thus, you may use it on either side to use the firmness as per your preference.

Aftercare to stretch the lifespan of memory foam mattresses

2. Clean the foundation and mattress

The foundation of your mattress relies on your platform, bed, or box spring. If you have framed your bed that is sturdy with center support, your mattress will have a longer life.

A firmly supported mattress prevents sagginess for long. Moreover, you must also clean the mattress and foundation. Follow processes like vacuum cleaning, spot cleaning, and deep cleaning to extend the life of your memory foam mattress.

Flip the mattress over in time to sustain its firmness. Certain manufacturers as we stated specially design different firmness on either side. By rotating at intervals you can extend your memory foam mattress’s life.

You need to save the mattress from the mischievous kids at home. They are habitual of jumping in bed. This can break down your memory foam sooner than you had expected.

Jumping on a mattress can not only spoil its quality, but also ruin the spring, foam, and foundation of the mattress.

Let your mattress get exposed to sunlight. The sunlight will help get rid of the bedbugs, moisture, and unpleasant smell.

  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?

    1. 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!
