Down, feather and polyester pillows dry well on low heat. Memory foam and latex must never go in a dryer. Here is the safe method for each type, plus how to fluff a flat pillow.
Short answer: most pillows can go in the dryer, but not all of them, and the ones that cannot will be ruined by a single cycle. Memory foam and latex are the two that stay out. Down, feather, polyester fill and most fiber pillows dry fine on low heat, and the dryer is actually the best tool for restoring their loft. Below is the full breakdown by pillow type, plus the drying method that keeps a pillow fluffy instead of lumpy.
Down and feather pillows are the ones that benefit most. Drying separates clumped clusters and puts the loft back. Use the lowest heat setting your machine has, or the air-fluff setting if the pillow is delicate. Add two or three clean dryer balls, or a couple of clean tennis balls in a sock, to keep the fill moving. Expect this to take a while. A wet down pillow can need two or three full cycles, and it must be bone dry inside before you put it back on the bed.
Synthetic fiberfill handles the dryer well and dries faster than down. Keep the heat low anyway. Polyester fibers can melt or fuse at high temperatures, and a fused pillow goes flat and stays flat. Dryer balls help here too.
This is the important one. Solid memory foam should not go in a dryer at any temperature. Heat breaks down the foam structure, and the tumbling action tears it. Some shredded memory foam pillows have a removable cover that is machine washable and can be tumble dried on its own, but the foam fill itself needs air drying. Lay it flat somewhere with airflow, out of direct sun, and turn it every few hours. Give it a full day or more.
Natural and synthetic latex both degrade with heat, and latex is heavy enough when wet that a dryer drum will misshape it. Air dry flat, away from sunlight, which yellows and hardens latex over time.
Buckwheat hulls, millet and similar fills are meant to stay dry. Empty the hulls out, wash and dry the casing on its own, and spread the hulls in the sun for an hour if they need refreshing.
You do not need to wash a pillow to use the dryer on it. Fifteen to twenty minutes on air fluff or the lowest heat, with dryer balls, lifts dust out, restores loft and makes a tired pillow feel noticeably better. This works on down, feather and polyester pillows and is worth doing every month or two between washes. It does not work on memory foam or latex, which should simply be vacuumed with an upholstery attachment and aired out.
One thing worth knowing: heat is often suggested as a way to kill bed bugs or dust mites in bedding, and a hot dryer cycle does help with washable items. But the temperature needed is high enough to damage most pillow fills, so it is not a routine maintenance step. If you are dealing with an active infestation, our guides on cleaning a mattress cover the safer approach.
Drying restores loft, but it cannot rebuild fill that has broken down. The fold test is the quickest check: fold the pillow in half and let go. A pillow with life left springs back. One that stays folded is done. Persistent yellow staining, a lumpy feel that no amount of fluffing fixes, and waking up with neck pain are the other three signals. Most pillows are ready for replacement every one to two years, sooner for cheap polyester and later for high-quality down or latex. Our guide on how often to replace your pillow goes into the timing, and how to choose a pillow covers picking the right loft for how you sleep.
If a new pillow does not fix the neck pain, the mattress underneath is usually the real culprit. A bed that has lost support at the shoulders forces your pillow to do work it was never designed to do. Our pressure-relief mattresses collection is a good place to start, and a mattress topper can buy you time if a full replacement is not in the budget yet.
Yes, for washable fills like down, feather and polyester. Wash two pillows at a time on a gentle cycle with a small amount of mild detergent, run an extra rinse to clear soap out of the fill, then move straight to a low-heat dryer cycle with dryer balls. Memory foam and latex pillows should skip both the washer and the dryer.
No. Heat degrades memory foam and the tumbling action tears it apart. If the pillow has a removable cover, that cover can usually be washed and tumble dried on low by itself. The foam core should be spot cleaned and air dried flat, away from direct sunlight, for at least twenty-four hours.
Put the dry pillow in with two or three dryer balls and run fifteen to twenty minutes on air fluff or the lowest heat setting. The balls beat the fill apart as the drum turns, which is what restores the loft. Shake the pillow out by hand afterwards.
Sustained high heat does kill bed bugs, but the temperature required is hot enough to damage down, latex and many synthetic fills, so it is not a safe routine treatment. If you suspect bed bugs, deal with the mattress and frame first, since that is where they actually live, and use a sealed encasement rather than relying on the dryer.
Polyester and down alternative pillows usually take forty-five to ninety minutes on low. Down and feather pillows take considerably longer, often two to three hours across multiple cycles, because moisture hides deep in the cluster. Always test the center before calling it done.
