When's the Best Time to Replace Your Mattress

Getting a good night's sleep is essential for living a healthy life. After all, happy and well-rested people are more productive, perform better at work, maintain relationships, and even have a lower risk of injury or illness.

It's time to replace your mattress if one or more of the following apply:

  • Your mattress is six to eight years old
  • Your mattress is negatively affecting your sleep
  • Your mattress has abnormally sagged or has any noticeable damage in certain areas
  • Your mattress is making more noise than usual (noisy springs are common in old innerspring mattresses)
  • You find that you sleep better at hotels, friends' houses
  • You notice an increase in allergies and asthma
  • You regularly wake up with muscle or joint stiffness

Factors That Affect a Mattress' Lifespan

Shoppers should keep various factors in mind when determining when to replace their mattresses. In general, the following vital factors impact longevity:

1. Material

Different mattress materials have different lifespans. Innerspring mattresses typically last slightly longer than foam mattresses. However, these estimates apply to high-quality mattresses made with durable materials and high-quality construction.

2. Frequency of Use

Mattresses that see frequent use, like those in hotels and guest rooms, stand a better chance of lasting longer than those in bedrooms. This is because mattresses receive more wear and tear in regular bedrooms, such as pets, children, and other sources of regular activity.

3. Maintenance and Care

The way you care for your mattress has a tremendous impact on its lifespan. Like regularly rotating your mattress and regularly flipping it, simple things can severely impact how long your mattress lasts.

4. Sleeper Size and Weight

The greater the weight and size of the sleeper, the shorter the mattress's lifespan. Again, this is due to the increased pressure and wear and tear, such as tossing and turning, placed on the mattress.

5. Sleeping Position

Stomach sleepers are tough on mattresses, as they place the most pressure on the mattress and place their heaviest limbs (shoulders and pelvis) on the mattress surface. Side and back sleepers also cause mattresses' high-stress levels, though to a lesser degree than stomach sleepers.

Is a New Mattress Worth the Cost?

While it's important to understand how long your mattress will last, it's also important to know that a mattress can last much longer than its warranty or estimated lifespan. When determining whether to replace your mattress, consider all of the factors that affect the lifespan of your mattress, including the cost of a replacement.

For example, an innerspring mattress that costs $400 and lasts ten years before needing replacement will cost $130 per year, assuming you don't take advantage of any mattress deals. If you find a comparable, high-quality innerspring mattress on sale for $200, the new mattress will only cost $66 per year. That saves $66 per year by not replacing your existing mattress and keeping it for another ten years.


With a little bit of research, shoppers can learn how long a mattress will last. However, to really make an informed decision about your mattress, you should also consider the cost of a replacement, such as the wide range of variables that can affect the lifespan of a mattress.
