How long does memory foam last?

Studies have shown you are going to spend about 8 hours a night sleeping for the entire life of yours, so it’s 25-30 years of snoozing to be exact. If you are going to be lying down for that long and doing nothing, it will only make sense if you do that by finding the most comfortable bed for you.

Just like, choosing any household furniture that will be going into your bedroom is an important decision to make, choosing a bed to sleep on, a mattress to use with it, which mattress topper will go with your mattress, will you need any mattress topper pad or not, how many sheets you will need to buy for your bed, these are also very important decisions to make.

You should be prepared to pay a little bit of money if you want a quality bed. For having a quality bed, you will need a quality mattress, and memory foam is a common type of mattress that people use for their comfort.

What Is Memory Foam?

Memory foam has evolved in recent years, in mattress construction technologically advanced foams are common materials. Memory foams are famous for their durability.

Polyurethane, the basic kind of memory foam is made out of polymer. You will find it in most sofas, mattresses, and car seats. It is known for providing good support, excellent pressure relief and has a high enough density.


Traditional Memory Foam: It delivers a good sleep experience by molding to your body. This particular type has one biggest disadvantage, that it retains body heat, and will make you feel uncomfortable while sleeping. To resolve this issue the other two types of memory foam were made.

Gel Memory Foam: It is the kind of memory foam that has been filled with full of gel, which has two different kinds.

The first kind just absorbs heat. The other kind is called a phase-changing material. By absorbing and releasing the heat it helps to regulate your temperature.

Open Cell Memory Foam: It is a basic memory foam with a different internal structure. This memory foam allows air inside the mattress to transfer the heat away from your body while sleeping.

Why memory foam gets softer as it becomes hotter?

The viscosity of memory foam depends on its temperature. The hotter the memory foam gets the less viscous (more flexible) it becomes.

The problem with ordinary foam is that it isn’t breathable. As, the foam isn’t ventilated, so it can’t disperse heat. This can be a real problem with your mattress. Sometimes memory foams are made from reticulated foam. They are not solid foam. An open-celled structure they have, that promotes ventilation and allows heat to disappear from your body.

Hygiene of memory foam

Apparently, bed bugs don’t like living in the foam, so high-density foam mattresses are appeared to be more hygienic. Some memory foams are manufactured with antibacterial agents and deodorants with polymer mix to improve hygiene.

Benefits of a Memory Foam Mattress

Ideal support and comfort

To give optimal spinal alignment and targeted support, memory foam contours to the shape of your body.

Generates pressure-point relief

This foam will eventually distribute your weight to reduce pressure on the heaviest parts of your body. It will promote healthier blood circulation throughout the night and will relieve the aches and pains of yours.

Controls of movements

It creates a personal sleep zone by contouring to your body, which will prevent you from feeling your partner tossing and turning. If you are often awake during the night, for this reason, buying a memory foam mattress will be a good decision for you.

Suitable for every sleep position

This product is capable of adapting to any sleep position.

Side sleepers: memory foam supports your waist to keep your spine in healthy alignment by distributing body weight away from your hips.

Back sleepers: memory foam suits to your spine, by offering excellent lumbar support.

Stomach sleepers: it supports the natural curve in your back by reducing pressure on your lower back. If you belong to the huge group of people who prefer this sleeping position and consider buying a new mattress, look no further and find the one that suits you the most.

If you keep tracking on your sleep cycles and establish a sleeping routine, you have a high chance to reach a quality jump and wake up refreshed every morning.

How Long does Memory Foam Last?

Typically, a memory foam mattress lasts longer than an innerspring mattress. From an average memory foam mattress, you should expect to get 10-15 years of support and comfort.

A superior lastingness can be attributed to the materials of memory foam. There are so many factors that will determine how long a memory foam will last.

Density: the weight of one cubic foot of material is called foam density. Any denser foam will deliver a more tightly packed cell structure. If you have a low-density mattress, it will support 1.5LB per cubic foot, and a medium-density mattress will support 2-3LB per cubic foot. A mattress of high-density can support 4-6LB per cubic foot or even more. They contain high resistance to stress factors.

Effects of foam density in the life of a mattress

Tensile strength

The strength which measures stretching limits is called tensile strength. Studies have shown, high-density mattress protracts to 25%-30% of its original dimensions and low-density protracts to 40% more. For the high-density mattress, it takes more time to reach the breaking point, compared to the other two types.

The rebound pressure

We all have seen children jumping and dancing on memory foam in our house. Due to the rebound pressure offered by the foam, they bounce on the mattress.Representing rebound pressure: siblings jumping on a mattress

Pressure relief points on the mattress can work more efficiently if this factor is higher. The top two memory foam layers carry the weight without experiencing the extra stretch. It also gives better contour support, increases coziness and comfort factors.

The thermal conductivity

The specific design principles follow two specific methods of dispersing heat. As, heat-absorbing gel memory foam mattress isn’t capable of retaining the heat, so the risk of rupture can increase within a few years.

The best method for pain and pressure relief is to convert heat into energy.

Shock absorption

Mattress with low density can absorb shocks from abrupt posture change and the cells will start breaking down. So, you will have to change the foam layer frequently. If you keep the rebound pressure high, it can reduce the impact of shocks on the foam layers.

Foam construction

While resting it is possible to provide good support to your body by increasing base foam thickness to 6”. Studies have shown, transition foam of 3” and memory foam of 3” with gel memory foam of 3” thickness, increases the lifespan of your mattress by 5-6 years.

Taking Care of Your Memory Foam Mattress

How long your memory foam will last depends on how you will take care of it.

  • Your bed base has to be supportive.
  • To even out concentrations of body weight on specific areas of the mattress you will have to rotate your mattress head-to-foot regularly. The ideal duration would be once in a month.
  • Use a waterproof mattress protector to prevent spilling liquids.


To remove dirt and particles you have to vacuum your memory mattress once in a week. To regulate pressure, you have to make sure to use the upholstery attachment.


To eliminate the harmful elements from your memory foam mattress you can use antifungal and anti-infectious sprays. But you have to check that they are free from moisture and dry off normally.


After cleaning dry the memory foam mattress in the open air without exposing it to the direct sunlight is one of the safest and simplest methods after cleaning. It also eliminates the pungent smell of the spray.

The Durability of Memory Foam

Due to the unique properties of foam, the memory foam mattress is one of the most durable types. Year after year this memory foam molds to the contour of your body and then quickly go back to its original shape after you’ve woken up.


When you are working out the quality of the memory foam is an important fact to consider. Usually, higher quality memory foam lasts longer, while lower quality foam tends to break down and deteriorate more easily.

The quality of foam should be measured by its density.


Of course, a good quality memory foam will come with a coverage of 10 years. Don’t buy imported cheap kind while picking a mattress. Yes, a good mattress might be a little bit expensive, but that’s the price you should pay for a good quality of sleep, and a good quality memory foam mattress will come with 10 years of pro-rated warranty at the least.

When it’s Time to Replace
