So, you’re thinking about getting a new mattress, and specifically a memory foam mattress?  Before you buy anything, you’ll want to gather some information about memory foam, and especially about the quality of the mattress and also how long it will last.  Or perhaps you are looking at replacing your existing memory foam mattress.

Either way, you’ve come to the right place!  This article will explain how long memory foam mattresses typically last, as well as the factors that can influence longevity, so you can make sure you treat your memory foam mattress with the best care.

Memory Foam Longevity

  • Memory foam material was originally developed by NASA back in the 1970s to protect test pilots during flights and in the event of a crash, and improve seat cushioning.  So, the initial application of the material was for pretty heavy duty situations!

  • Memory foam mattresses are typically made with high quality materials and methods, and thus last at least as long as other common types of mattresses, including innerspring and hybrid mattresses.

  • The main characteristic of memory foam mattresses that keeps them going for a long time is their density.  Typically, high quality memory foam mattresses will feature a density of around 4 lbs./ft3.  Compared to other foam mattresses like polyfoam, memory foam typically has a higher density, and will thus last longer.

  • If you notice that one mattress is significantly less expensive than the others, it’s likely that it’s density is markedly lower, and will therefore sag and lump up more easily and be less durable.

  • If you’re big and tall and have a higher than average body weight, you should consider getting a higher density memory foam, around 5 lbs/ft3.  This will ensure your mattress will last as long as possible.

  • Each memory foam mattress should come with a warranty, usually spanning 5-10 years or somewhere in between.  With good care though, your mattress can last for even longer than the warranty period.

What Determines How Long a Memory Foam Mattress Will Last?

As mentioned above, density is a big factor when it comes to memory foam longevity.  Usually, more dense memory foam will last longer.  In addition to this, however, how you treat your mattress will also determine how long it lasts.

How Do I Know When to Replace My Memory Foam Mattress?

  • Sagging on one side or in one part of the mattress
  • The mattress has developed lumps, ridges or bumps
  • If you notice yourself feeling more and more allergy symptoms, your mattress may be saturated with allergens
  • Body impressions on the memory foam last much longer than they did originally, or don’t go away at all
  • Recent difficulty falling asleep or staying asleep on the mattress

Memory Foam Durability

Because most memory foam mattresses are made with durable, high quality materials, they tend to last for a fairly long period of time, typically between 8-10 years.  Nevertheless, it’s still certainly worthwhile to know how to properly care for your mattress, and how to spot the signs of a worn out mattress.
