How Often Should I Change My Mattress?
Signs You Should Change Your Mattress
Typically, you should change your mattress every eight years to ensure optimal comfort and restful sleep. However, some mattresses get worn out quicker and keep users from sleeping well. If you wake feeling stiff or numb or feel achy and pained throughout the night, it is likely your mattress is no longer providing the support you need. If you sleep with a partner, check in with them about their experience. If you are both disrupted throughout the night, it is time to look for a new mattress.
Additionally, extreme sagging, lumpiness, and dents in your mattress are signs that it's time for a change. Lifestyle variations, such as sudden weight gain or recently developed back problems, also have an effect on when your mattress needs to be replaced.
