Mattress lifespan is a term which describes how long a mattress can continue to be in its same shape, give the same comfort and continue to give the same support, very close to when it was new.

It is how long a foam mattress can last. As we all know, mattresses deteriorate after some point time, and that the lifespan of any mattress depends on various factors like the quality of its material, care, manufacturing quality etc.

A poor-quality mattress can deteriorate in a very less amount of time, say in one or two years, while a good-quality mattress can last for more than twenty years. The mattresses having an innerspring core last for about ten to twelve years. All the mattresses that are now being made recently are two layered in order to increase their lifespan.

Considering the rigorous use of a mattress, its lifespan can reduce, therefore, presently, some of the mattresses are being provided with a separate topper which is also replaceable and reduces the wear and tear. It can be replaced without changing the whole mattress.

So, how long will a memory foam mattress last? We can expect a memory foam mattress to last between 4 and 10 years.  This figure largely depends on the foam density and the care of the mattress.  Read on for more information.

Mattress Warranties

In the UK, the warranty of mattresses is more than ten or twenty years, which means that they see to it that there are no manufacturing defects or no faster deterioration which enables the consumer to trust that brand.

The expectations of a mattress lasting a long time are dependent on various numbers of factors such as sale price, its manufacturing quality, the material or foam used to make it, and the length up to which its warranty period can last, like saying ten to twenty years.

The majority of wear and tear problems that can occur which can, to some extent, reduce the lifespan of a mattress are staining, sagging and mildew etc. These factors can be prevented by giving the mattress proper support, flipping it, keeping it dry, rotating it and by using a mattress protector or a pad.

Some of the symptoms of a worn-out or broken mattress are the springs that can be felt coming out or poking from within the upholstery layer, lumpiness, sagging, which is permanent, deformity, excessive squeaking etc.

Keeping A Mattress In Good Condition

All the mattresses need a solid base or foundation which does not sag because if the base is sagging, such as by very weak slats on a very wide bed, it can itself cause the mattress to sag. Plus sleeping in the same spot on the mattress in the same position can cause the wear and tear of a mattress, therefore one should keep rotating the mattress on a weekly or on a monthly basis to reduce it.

The advantage of having a double-sided mattress is that it can be flipped both lengthwise and breadthwise or it can be alternately rotated or flipped, whereas the single sided mattress can only be rotated which is less effective, but is very simple. Rotation/flipping schedules can vary between manufacturers and materials, but it is typically recommended that the mattress should be flipped every month for six months and then decreasing to two and three months after that.

Sagging is very undesirable but in some mattresses, the level of hollowness is natural like about 3.1 inches, that is 8.1 cm, which can be used in the comfort layer. Doing excessive amount of wear on mattresses such as bending and folding and pressurizing and placing very heavy objects on a specific area or spot can also cause the deterioration of a mattress thereby decreasing its lifespan. As the mattresses are sophisticated, care should be taken particularly at the time of transporting them or carrying them and storing them.

Keeping the mattress dry is also very important, as moisture can reduce its lifespan, therefore the mattress requires ventilation in order to remain dry and to prevent mildew. It is therefore recommended that the mattress not be placed on a solid surface or floor directly. A box of spring or slats provides a large amount of area for airflow whereas plywood or solid wood do not provide many areas for airflow.

One other method for ventilation is leaving the mattress bare for a few minutes after removing the sheets. If a mattress has become damp after wet cleaning, then mildew may form. Therefore, cleaning with the help of a vacuum cleaner or with the help of a damp cloth or with the help of a mild cleanser is very beneficial.

Any mattress can get stained very easily as it can readily absorb any fluid which is majorly from night sweating, which produces yellow stains on the mattress, or from menstrual fluid which produces dark red stains on the mattress, or any other body fluid, including accidental spills These can seep down to the lower layers and cause stains which are very hard to remove, thus making the mattress really unhygienic and hard to wash. Such stains reduce the warranty of mattresses and thereby reduce their lifespan.

Memory Foam Mattress Materials

The material that a mattress is made up of is very important for the durability of a mattress. In the case of memory foam mattresses, the core of the material and its density are very important to its long lifespan, durability, warranty and comfort. In the case of a memory foam mattress, the denser the mattress is, the more tightly and spaced cell core it has which affect the performance and feel of the finished product.

The range of low-density foam is between 2.0 lbs to 4.0 lbs, the range of medium density foam is between 4.1 lbs to 5.5 lbs and the range of high-density foam is above 5.5 lbs. Since there are numerous cells to support any sleeper’s weight, the memory foam mattress having a high density will last longer than the rest. But the high-density foam mattresses are not so comfortable to sleep on because of their high viscosity.

On average, the memory foam mattresses, having low density, have a lifespan of four to seven years. The high-density memory foam mattresses and medium density memory foam mattresses have a lifespan of eight to eleven years, which can increase or decrease depending on how care is taken of the mattress.

The second most important part of the memory foam mattresses is their foundation or the supporting base which is beneath the memory foam. This is the component which helps in supporting a sleeper’s body weight. Memory foam mattresses having a very low-quality foundation or base have much less lifespan.

The memory foam mattresses with innerspring have much less life span and are very poor in terms of durability as the padding layers compress very early and the inner spring that are non-replaceable lose their support, thereby decreasing the lifespan of memory foam mattresses.

With the help of waterproof covers and water resistant covers you can increase the lifespan of a memory foam mattress as it can protect the memory foam mattress from accidental spills or menstrual fluid which can stain the mattress dark red or night sweating which can stain the mattress yellow.

Any solvent or liquid can affect the durability or performance of a memory foam mattress. It is very unhygienic and can even produce odours. On average, a person secretes thirty thousand cells or more per hour in addition to other bodily fluids. If the memory foam mattress does not have a washable cover, then all these fluids can seep down to the lowest layer which is really very unhygienic and can even result in the silent symptoms of diseases which can happen to the sleeper as it can create a very unhealthy environment.

Many memory foam mattresses require a separate topper which is replaceable and can prevent the fluids from seeping down to the bottom layer, thereby creating a healthy environment plus it is very hygienic which also increases the lifespan of the memory foam mattress.

Maximising Memory Foam Mattress Lifespan

As every memory foam mattress needs a good support system like a solid wood base or platform bed, usage of a spring box which are widely spaced lead to faster deterioration or reduction of the lifespan of the memory foam mattress plus it also reduces its warranty and durability.

Memory foam mattresses are recommended more to be rotated than to be flipped. But one should not rotate it occasionally after the first six months as it will lead to its wear and tear, that is, one should rotate it after two to four months.

The lifespan of memory foam mattresses depends on its warranty, but sometimes this is not the criterion. As there are some companies who offer a warranty of one year, while there are some which offer a warranty of twenty years which clearly means the latter is more beneficial. But, the most important and required factor is the stipulation and coverage length, which in most cases is required to be full coverage.

There are many ways by which the lifespan of a memory foam mattress is unknowingly hampered, but at the same time, there are many ways by which they can be prevented from being damaged.
