Why shoulder clearance matters
When you lie on your side, the pillow fills the gap created by your shoulder. A firmer mattress usually leaves a larger gap; a softer mattress may let the shoulder sink farther.
Signs the loft may be wrong
A pillow that feels excessively high or low can be uncomfortable. Evaluate the complete setup—pillow, mattress, body position, and time spent in one position—rather than focusing on one feature.
Contour versus traditional shapes
Contour pillows offer defined zones, while traditional pillows allow freer repositioning. Combination sleepers may value flexibility; people who stay in one position may prefer structure.
