How long will a new mattress last? It depends. A combination of variables affects the length of time that a sleep set will provide optimum support and comfort. These variables include:

Quality
A poor-quality mattress set can deteriorate quickly, while top-quality sets can be expected to provide comfort and support for a number of years. As with other products, you get what you pay for.

Frequency of use
All things being equal, a sleep set in the master bedroom that is used on a nightly, continuous basis will lose comfort more quickly than one in a guest room.

 Weight
An adult who is heavy wears out a mattress more quickly than someone who is lightweight. And since two people weigh more than one, an adult who sleeps alone puts less wear and tear on their mattress than a couple who sleeps together.

Care
Proper care can extend the life of a mattress.

There is not one individual component that makes a mattress set good or bad. You need to select a mattress set that has a proper mix of quality components that fit your individual needs.
