How Long Do Memory Foam Mattresses Last (And Why)?

Exact Answer: 8 to 10 years

Memory foam is a type of polystyrene foam that has been treated with chemicals to give it viscoelastic qualities. Most memory foam is created with petrochemical products to give it its trademark contouring feel, however, some manufacturers substitute plant-based oils for some of the petrochemicals used to make memory foam, resulting in a more eco-friendly foam.

The term “memory foam” refers to the foam’s capacity to briefly retain the shape of an object pressed into it. Memory foam mattresses cradle the body and ease pressure spots such as the hips and shoulders. It relieves pressure practically everywhere on the body, including insensitive or painful locations. Its capacity to conform to the body makes it extremely effective for keeping the spine aligned regardless of the sleeper’s position.

The average mattress should last between 8 to 10 years. The density, firmness, and thickness of a memory foam mattress’s foam layers determine its endurance and lifetime. Within a few years, models with low-quality memory foam may begin to lose their capacity to bounce back or revert to their original shape.

The durability of memory foam is determined by several things. The first and most significant is density, followed by the following:

  • Materials used: The materials utilized in the manufacture of a mattress will have a significant impact on its longevity. Latex and high-density polyfoam can survive for a long time, however, low-density polyfoam wears out much faster.
  • Quality of the Original: The quality of your mattress when you first purchased it will influence how long it lasts. A low-cost, entry-level mattress will almost probably outlast a high-end hybrid mattress. While a larger price tag does not always imply a better product, more expensive mattresses frequently have a higher quality structure and tend to last longer.
  • Take Good care: As with other things in life, taking care of your mattress will extend its lifespan. Routine cleaning, the use of protective coverings, and according to manufacturer care instructions are all part of proper mattress care. Some mattresses can be flipped or turned regularly, but consult the manufacturer’s instructions first.
  • Body Weight & Sleeping Position: Your sleeping posture and body weight will influence how quickly your mattress wears out. Heavier sleepers may experience premature drooping of their mattresses, whereas side sleepers may have excessive sagging around the hips and shoulders.

Damage, noisy springs, morning muscle stiffness, putting extra weight on your mattress, and a change in your sleeping arrangements or health are all reasons you may need to replace your mattress. If you discover these and other causes, it is time to get a new mattress.

The purpose of replacing your mattress is to be more comfortable. A mattress can lose its shape and begin to droop over time, causing dips and lumps. An uncomfortable mattress might make it difficult to get a good night’s sleep. Sleep deprivation has been linked to several problems, including heart disease, kidney disease, and diabetes.

Why Do Memory Foam Mattresses Last For So Long?

Mattresses require a proper base to last as long as the maker promises and to be comfortable. Each manufacturer has its own set of rules, but you should check to see if the mattress may be used with a solid, slatted, or adjustable foundation. The warranty is only valid as long as the mattress is properly supported, and for good reason: incorrect support can cause early sagging, indentations, or loss of shape.

Memory foam softens over time. To standardize wear and tear, some manufacturers advocate rotating the mattress from head to foot once a month for the first six to twelve months and then every few months following.

Memory foam has a natural resistance to dust mites and other allergens, which is one of its advantages. Mattresses, however, must be cleaned regularly. Removable covers and machine washable should be laundered regularly.

With a little extra care, you might be able to extend the life of your mattress. You can do the following steps:

  • To protect your mattress from spills, dust, and debris, use a mattress protector.
  • Ascertain that your mattress is appropriately supported with the appropriate box spring or base.
  • Allowing your children to jump on the bed might harm the coils and other mattress components.
  • To allow your mattress to breathe, remove the sheets and mattress covers regularly.


Memory foam mattresses, when made with the correct foams, can last much longer than the eight to ten-year average. Memory foam mattresses are a great way to improve your sleep health.

A memory foam mattress does not have an indefinite lifespan. Vacuuming regularly can help keep allergies and dust mites at bay. You can also sprinkle baking soda on your mattress and vacuum it 24 hours later to help remove retained moisture and odors. Mattresses should be cleaned once a year, with spot cleanings as needed in between.
