There is no single replacement schedule that applies to every pillow. Material quality, use, care, and personal comfort all matter.
You also do not necessarily need the most expensive mattress or pillow available. A supportive product that fits
your body and sleeping position may be more useful than one marketed with exaggerated health claims.
10. Is a Firm Mattress Always Better?
Many people assume that a hard mattress is automatically healthier for the spine.
But mattress firmness is not a universal measure of support.
A mattress that is too soft may allow some areas of the body to sink excessively. A mattress that is too firm may create uncomfortable pressure around the shoulders and hips, particularly for side sleepers.
The most appropriate mattress depends on your body shape,
preferred position, comfort, and any underlying pain conditions.
If you wake up sore every morning, consider whether your mattress has developed uneven areas or no longer supports you comfortably.
