What is pillow loft?

Pillow loft is the height or thickness of a pillow when it supports your head and neck.

What pillow loft is best for side sleepers?

Side sleepers often need medium-high to high loft, depending on shoulder width and how deeply the mattress lets them sink.

Can the wrong pillow loft cause neck pain?

It can contribute to neck strain if it bends the neck too far upward, downward, or sideways for long periods.

Loft depends on position

Side sleepers usually need more height, stomach sleepers need less, and back sleepers often need a medium loft that supports the neck without pushing the chin forward.

Mattress firmness changes the gap

A softer mattress lets shoulders sink farther, often reducing pillow height needs. A firm mattress can leave a larger gap for side sleepers.

Adjustability is useful

Shredded foam, latex fill, and adjustable inserts make it easier to fine-tune loft after a few nights of real sleep.

How should I care for my pillow?

Follow the exact care label. Some covers are washable while their inserts are not. Reassess comfort if the fill stays flattened or clumped; replacement timing varies by material and use.
