How to Fix a Flat Pillow Without Buying New
Fluff and reshape a flat pillow, match the method to its filling, and check the care label before washing or drying.
In brief: You can fix a flat pillow without buying a new one by gently reshaping it and moving loose fill into the thin spots. Check the pillow's care label before washing, drying, or making another adjustment. Worn-out filling may look fuller afterward without regaining its original loft.
Three things to remember
- Try reshaping the pillow by hand first.
- Match your method to the filling and care label.
- Dry a washable pillow completely before using it.
Take off the pillowcase and feel the pillow. Has the middle gone thin, or has the filling bunched up in a corner? A loose clump may respond to your hands; a dent that stays put can call for a different approach.
Why pillows go flat
Filling can shift away from the middle or become compressed with use. Loose fill may collect in the corners. It can form clumps, too, leaving one part of the pillow thicker than another.
Foam can develop a lasting dent rather than a movable clump. Turns out, a pillow that looks fuller isn't necessarily firmer: it may still squash down easily when you lie on it.
Start with a hands-on reset
For a loose-fill pillow, hold two opposite ends and push them toward each other. Release them and repeat a few times. Turn the pillow and do the same from the other direction.
Next, feel for lumps through the cover. Work them apart gently, then shake or guide the filling toward the thin areas. You might move some fill toward the middle, find another thin patch, and have to move it again before the pillow feels even.
Put the pillowcase back on and try the pillow in your usual position. Does it settle back into the same flat shape quickly? Check the filling before trying another fix.
Match the fix to the filling
Not every pillow responds to fluffing. Use the filling to choose what to do next.
| Filling | What to try | What to expect |
|---|---|---|
| Polyester or other loose synthetic fill | Gently separate clumps and move filling out of the corners. | The shape may become more even, though some clumps may remain. |
| Down or feathers | Press and release the pillow, then shake the filling toward the middle. | It may look loftier without feeling firmer. |
| Solid foam | Check the care label and rotate the pillow if its design permits. | Fluffing can't rebuild a lasting indentation. |
| Buckwheat hulls | Lay the pillow flat and guide hulls toward the thin spot. | You can reshape it, but it won't become fluffy. |
Handle solid foam gently. Don't knead it forcefully, machine-wash it, or tumble-dry it unless the manufacturer specifically permits it. The removable cover may be washable even when the foam isn't, so check the instructions for each.
Wash or dry only if the label allows
Cleaning may loosen clumped filling in some washable pillows, but the washing machine isn't the place to start when you don't know what the filling can take. Find the label on the pillow itself. The instructions for its removable cover may be different.
Caution: Don't assume that water or dryer heat is safe for the filling. Follow the pillow's own washing and drying instructions, and let a washed pillow dry completely before putting it back in its case.
Check the label before using a dryer on its own, too. If tumble-drying is allowed, use the specified settings rather than guessing at a temperature.
Reshape an adjustable pillow
A pillow with an opening made for adjusting the fill gives you another option. Move the contents around first, then close the opening and try the pillow again. With buckwheat hulls, push them toward the area that feels thin.
Thing is, you may not need to add anything. If the pillow is designed for extra fill and you already have compatible material, add a little at a time. Close the opening securely and check the height before adding more.
Keep any hulls you remove in a clean, dry container.
Know when fluffing has reached its limit
Give the reshaped pillow a few nights in your usual position. Pay attention to whether the filling stays where you moved it or slips back into the same uneven shape.
Some worn-out materials won't regain their old loft. Fluffing can't put crumbling foam back together, and fill that no longer holds its shape may flatten again.
Stop trying to revive the pillow if you see mold or if a musty smell remains after cleaning permitted by the label.
Frequently asked questions
Can you put a flat pillow in the dryer?
Only if its care label permits tumble-drying. Follow the settings on the label rather than guessing at the temperature, even if you aren't washing the pillow first.
Can you add stuffing to an old pillow?
You can add compatible fill you already have if the pillow has an opening designed for adjustment. Add a little, close the opening, and check the height. You can then decide whether to add more.
Can you make a buckwheat pillow fluffy?
Buckwheat hulls are meant for reshaping rather than fluffing like down. Move the hulls toward the part of the pillow that feels thin. An adjustable option such as the LilyPillow buckwheat hull pillow also lets you change the amount of fill.
The bottom line
Start with your hands, not the washing machine. Feel for the thin spot and move loose filling toward it, using a method that suits the material. Check the pillow's label before washing or drying, then try the new shape for a few nights to see if it holds.
