Memory foam is the most durable and resilient foam designed by NASA. It is the foam that is popular for its pain-relieving properties, endurance, and longevity. These high-grade foams were made to resist and retain its shape and properties even in space with fluctuating gravity and speed. But do these high-quality foams ever worn out? The answer is yes, they do! Anything, no matter how robust or high quality eventually wears out. Nothing can last forever. Tough, In comparison with other mattresses the life span of memory foam is the longest.
The question that arises here is how long can a memory foam be useful for and when do we need to change our mattress?
THE AVERAGE LIFE SPAN OF A MEMORY FOAM
Being the most long-living type of foam, its average life span might vary from type to type. Memory foam with higher density and higher thickness can be used way more than foam with low-density low thickness because denser foams are better in quality and do not wear out soon. Factors like cleanliness, hours of use, and most used areas, and odors usually determine if it is time to replace it with the old one. However, a low quality/ less dense memory foam can live up to 5+ years and high quality can serve well for 10, 12, or in some cases even 20 years.
WHAT DETERMINES THE LIFE OF A MEMORY FOAM?
After you have completed your warranty period, there are a few indications that you will notice. Those indications will determine if your king memory foam mattress needs to be replaced.
One of the properties of memory foam is that it distributes your body weight evenly on to the mattress by which your body feels relaxed. When the foam density deteriorates, the foam starts to sag and your body feels uncomfortable. The foam loses its ability to maintain or retain its shape and tend to sink.
MOVEMENT CAUSING DISTURBANCE
When the bed becomes stiff or loses its ability to bounce, that’s when it needs to be replaced. It is the other drawback of an old and sagging bed that if one partner moves slightly, the movement will be felt on the other side as the bed will not be bouncy or resilient anymore. Saggy beds can not only cause disturbance but will also fail to provide rest to your back and neck and you’ll wake up tired.
CLEANLINESS AND ODOR
This factor completely depends upon the user. The more you maintain your memory foam or keep it clean the more life it will have. A mattress with a bad odor or a dirty bed is something that can not only cause trouble in sleeping but can also lead to skin problems and headaches. It is very important to saves it from falling food, change bed sheets often, and not lie on it while you are sweating.
But once it retains a certain type of odor that does not leave no matter how much you try, then there is no other option than to change it.
