Pillow guide

How pillow fit actually works.

What loft means, how mattress firmness changes it, why creep matters, and how to tell when your pillow is the wrong height.

What this guide covers

Most pillow shopping asks you to translate symptoms ("my neck hurts") into product labels ("medium loft, plush feel") that don't agree across brands. These guides explain the variables that actually change pillow fit, in plain language, so you can read a product page without having to guess what the words mean.

Frequently asked

Quick answers.

What is pillow loft?

Loft is the height of the pillow when there's nothing on it. It's a useful spec but not a complete one — a pillow that measures 150 mm uncompressed might compress to 80 mm under your head. The number that matters for fit is height-under-load, not uncompressed loft.

What's the difference between loft and firmness?

Loft is height; firmness is how hard the pillow pushes back. Two pillows can share the same loft and feel completely different at the head. Maple specifies both with measured numbers (loft in mm, firmness as IFD25 in newtons) so you can compare across our profiles.

Does mattress firmness change pillow loft?

Yes — significantly. A softer mattress lets the shoulder sink with the head, raising the head relative to the spine. That changes how much loft the pillow needs to provide. Maple's fit logic adjusts the recommended loft by ±8 mm based on mattress firmness.
