How Long Does A Memory Foam Mattress Last?

The important consideration when buying a memory foam mattress is the lifespan of the product. These mattresses can for a longer time than other mattresses. However, you’ll make a better decision if you consider several factors including the quality of the product, the density, and ease of care.

How Long Does A Memory Foam Mattress Last

The density, as well as the core of the mattress, predict the longevity of the mattresses. The denser types offer you with a perfect feel and provide you with the best performance. The denser the mattress the longer it will last.

So the higher density lasts for a longer period when compared to the low-density mattress. Most people, however, usually prefer to sleep over the medium density mattress. These models last for a longer period i.e. around 8-10 years. The lifespan of low-density mattresses can be as short as 4-6 years.

The second most important aspect regarding the longevity of the mattress is the density of the support base (core foam) used in the mattress. The core or support foam is usually the foam at the bottom of the mattress. If the mattress is reversible, the core level may be in the middle of the mattress.

First, the density of the core foam is not comparable to the density of memory foam. It will be easy to become confused if you don’t understand that the memory foam layers and the core foam layer are made from different types of foam. Memory foam is designed to compress and return to its original shape. Core foams are usually made from polyfoam which is not memory foam.

A low-quality support base reduces the longevity of the mattress. Classification of core foam can be confusing because the terms relating to them have not been well-defined. “High Resilience” (HR) refers to a type of polyfoam that is considered higher quality than polyfoam that cannot be called “High Resilience.” You may see polyfoam referred to as “highly resilient.” Be aware that “highly resilient” refers to the bounce and does not refer to the support the foam provides. We provide more clarification in this article, Clarifying Confusing Mattress Terms.

High-resilience memory foams are considered ideal with a core density beginning at 2.5 pounds. Low-density cores rated at less than 2.0 pounds can quickly break down, compress and get softer with time resulting in compromised longevity and support.

Although it is fair to say that lower density foams will break down faster than higher density foams, we don’t have published information that tells us that a mattress with twice the density will last twice as long. We only know that one will last longer but not whether that relationship is linear or compounded by other factors.
