How often should I replace my pillow?
It is recommended that you replace your pillow every one to three years. Depending on the type of pillow you have, you may need to replace it more or less often.
The best way to determine if it is time for a new pillow is to determine if yours is still doing its job. Your pillow should support your head and neck. Once you start layering different pillows or notice the pillow is not doing the job it was intended to do, it may be time to look for a new pillow.
