Pillow height controls whether your head stays centered over your shoulders or falls into a tilted position for hours at a time.
When the height is right, the neck feels supported, pressure spreads out more evenly, and it becomes easier to stay asleep without constant readjustment.
A quick rule of thumb
Choose loft based on your sleeping position first, then fine tune for shoulder width, mattress softness, and personal comfort.
- Broader shoulders usually need more loft.
- Softer mattresses can reduce the loft you need.
- Adjustable fill is useful if your preference changes night to night.
