Can You Put a Pillow in the Dryer? Fill-by-Fill Rules
The answer depends entirely on the fill, and getting it wrong is expensive: heat permanently crumbles memory foam and latex, and a pillow put away slightly damp grows mildew inside where you cannot see it. Always check the care label first — the rules below are what to do when the label is missing or unreadable.
What each fill can take
Sort by fill before you sort by convenience.
- Down and feather: dryer-safe on low heat. Add wool or plastic dryer balls to break up clumps. Expect 60 to 90 minutes and several cycles.
- Down alternative and polyester: dryer-safe on low. Faster than down, roughly 40 to 60 minutes, and also benefits from dryer balls.
- Solid memory foam: never. Heat and tumbling both destroy it. Spot clean and air dry only.
- Shredded memory foam: usually no heat. Many brands allow a no-heat air-fluff cycle — check the label, and air dry the fill otherwise.
- Latex: never. Heat degrades the rubber and tumbling tears it. Air dry flat, out of direct sun.
- Buckwheat: never put hulls in a dryer. Empty the hulls out, wash the casing only, and air the hulls in the sun.
- Kapok and wool: air dry. A no-heat tumble helps redistribute kapok clumps.
How to dry a washable pillow properly
The failure mode is a pillow that feels dry on the outside and is still damp at the core.
- Use low heat. High heat melts polyester fibers into hard lumps and scorches down.
- Add two or three dryer balls, or clean tennis balls in a sock, to keep fill from matting.
- Dry two pillows at once so the drum stays balanced.
- Pause every 20 to 30 minutes, take the pillow out, and knead the corners and center by hand.
- Test the middle: squeeze the core and feel for coolness or weight. Cool and heavy means still damp — keep going.
- Finish by air-drying for a few hours before putting it back in a case.
Air drying without a dryer
Foam, latex, and anything you would rather not risk should be air dried, and airflow matters more than sunlight.
Lay the pillow flat on a drying rack so air reaches both faces, turn it every few hours, and put a fan on it. Direct sun helps kill odor but yellows down and degrades latex, so give latex shade. Depending on humidity, a soaked foam pillow can take 24 to 48 hours — do not rush it back onto the bed.
