I changed mattress and my pillow stopped working

Required loft is your neck-to-shoulder distance minus how far the mattress lets your shoulder sink — so it is a property of the pair, not of you alone. A firmer mattress swallows less of the gap and leaves more for the pillow to fill; a softer one does the opposite. Nothing changed about your body or your pillow. The subtraction changed.

This is the clearest demonstration of why loft is not a fixed property of a person, and it is the situation that sends the most people looking for a pillow when what they need is a number.
