The “shelf life” of a mattress depends on several factors such as usage, quality and even your own changing comfort and support preferences. In general, a mattress set that has been in use for five to seven years may no longer provide proper comfort and support, and should be evaluated. A scientific study from Oklahoma State University, “Subjective Rating of
Perceived Back Pain, Stiffness and Sleep Quality Following Introduction of Medium-Firm Bedding Systems,” found that participants with mattresses five years old or older reported significant improvements in sleep quality and comfort when sleeping on a new mattress, regardless of the sleeper’s age or weight.
So it is important to compare the mattress and boxspring/foundation you are sleeping on now to newer models every few years. After all, a new mattress can make the difference in how you feel and function each and every day and help you Start Every Day With a Good Night’s Sleep™.
