The ideal pillow height depends partly on how you sleep and the width of your shoulders.
For side sleepers
A medium-to-higher pillow may be needed to fill the space between the head and the mattress, particularly for people with broader shoulders.
The goal is to keep the neck aligned rather than tilted toward the bed or ceiling.
For back sleepers
A lower or moderately supportive pillow may be more suitable, depending on its design and your body shape.
The pillow should support your head and neck without pushing your chin toward your chest.
For stomach sleepers
A thin pillow may reduce excessive neck rotation or extension. Some people prefer sleeping without a head pillow, provided this feels comfortable.
When should you replace your pillow?
Consider replacing a pillow if it has become flattened, lumpy, difficult to clean, or unable to provide consistent support.
There is no single replacement schedule that applies to every pillow. Material quality, use, care, and personal comfort all matter.
