Over time, mattresses become less comfortable as they age. Sleeping on an old mattress may actually negatively affect your wellbeing. You may be unaware of the fact, however, that old mattresses pose serious health and wellness risks. If you have an old, unsupportive mattress it is probably the time to consider to replace mattress, it is affecting the quality of your sleep. In addition to fatigue during the day soreness, fatigue, headaches and weakened immunity, migraines can also result in weight gain.

This guide will help you decide when it’s time to replace your mattress.

What is the Life Expectancy of a Mattress?

You should expect your mattress to last for roughly 7 to 10 years. A mattress can therefore be described as durable if it is made of a quality material and maintained and cared for to a degree.

The Following Factors Affect the Longevity of Mattresses:

  • Materials. The quality of a product significantly affects its duration. Poor quality products are likely to last less. The foundation of a mattress is crucial to its long-term durability. A good choice here is a spring, or a high-density foam.
  • Firmness. Because firmer mattresses are less likely to slump, they tend to last longer. It is still crucial to use quality materials.
  • Sleeper Size. As a result, if you weigh over 200 pounds, you may see it wear out faster when you have a mattress that is significantly heavier and larger.
  • Maintenance. The best way to get the most out of your mattress is to take proper care of it. If you have a double-sided mattress, you’ll want to rotate it every three months or so, and flip it every once in a while if necessary. A mattress protector is also a great idea, since liquids, body fluids, and other materials can damage the mattress.
  • Cleaning. Mattresses must be kept clean to prevent stains and extend their lifespan. However, children and pets using the mattress can make this difficult. The mattress can also be damaged by other factors such as stains and animal hair.

In terms of longevity, every mattress is unique. How long a mattress will last is largely determined by the firmness and mattress material, but cleaning and maintaining the mattress are equally important.

You want your mattress to last as long as possible because mattresses are expensive. Once your mattress reaches 7 years, even if you still like it, it might be time to look into getting a new one. You might be able to extend the life of your mattress by investing in routine mattress maintenance during this time.

To Prolong the Life of Your Mattress, Follow These Tips:

  • In addition to protecting the mattress from liquids, bodily fluids and dust, a mattress protector prevents dead skin and skin cells from accumulating on the surface.
  • Keep your children from jumping on your bed and don’t eat or drink in it.
  • A solid foundation or box spring is needed to properly support the mattress.
  • Sleeping on different parts of your mattress every three months will prevent indents if you shift the position of your sleeping surface.
  • Dust mites and other allergens can be removed from your mattress by vacuuming it twice a year at the very minimum.
  • At least once every year you should deodorize and clean your mattress. Vacuum the mattress after it has been saturating in baking soda for 24 hours.

Your mattress will last longer if you take care of it soon. This might be useful after your mattress has reached its fifth or sixth year, but it is best if you begin cleaning and maintaining it right after it is delivered home.
