Questions, answered
How do I know my correct loft?
Lie on your side and have someone check that your nose lines up with your sternum. If your head tilts down, add fill; if it tilts up, remove fill.
What do I do with removed fill?
Store it in the bag most adjustable pillows include. Shoulder width and mattress firmness change over time, so keep it for future tweaks.
Do adjustable pillows go flat?
Shredded fills compress with use but can be refluffed, and you can add stored fill back in. This is a major longevity advantage over fixed pillows.
Are adjustable pillows good for couples?
Excellent. Partners with different builds can each tune their own pillow instead of compromising on one fixed loft.
