The best way to store down pillows is clean, bone dry and loose inside a breathable cotton bag, on a shelf in a cool, dry room. That is really how to store down pillows in one line: no plastic, no vacuum sealing, nothing heavy piled on top. Do those three things and a pillow can sit for a season and come back soft.
The details matter more than people expect. Most pillows that come out of storage flat or musty were put away a little damp, squeezed into a small bag, or left in an attic or basement. Below we cover each step, the common mistakes, and how to bring a pillow back to full loft.
Why does storage matter so much for down?
Down is not a solid filling. Each cluster is a soft puff of fine filaments, and the loft you feel when you press a down pillow is air held between them. Keep the clusters dry and uncrushed and they spring back. Wet them or flatten them for months and they start to stick together.
Down also takes on moisture from the air. A pillow left in a humid room slowly gets heavier and limper, and if that moisture has nowhere to go, the fill can start to smell. If you have ever opened a closet in spring and caught a faint wet dog note, you know the feeling.
So learning how to store down pillows really comes down to two things: moisture and pressure. Every tip below goes back to one of them.
How to store down pillows, step by step
Here is the routine we follow for spare pillows, guest room pillows and anything put away for more than a few weeks.
1. Clean it first
Sweat, skin oils and the odd drop of hand cream do not disappear in a closet. Over a few months they can leave yellow patches and a stale smell. If the pillow has been slept on since its last clean, wash it before it goes away. Our guide on washing goose down pillows at home without clumping the fill covers the cycle, the detergent and the drying in detail.
If a guest used it for a night or two inside a protector, a good airing is usually enough. Leave it somewhere with moving air for an afternoon, out of harsh sun.
2. Make sure it is completely dry
This is the step that decides everything. Damp down packed into a closet is the classic recipe for clumps and mildew smell. The care notes for our own goose down pillow say the same thing plainly: natural down must be completely dry before use or storage.
The outside of a pillow dries long before the middle. Squeeze the center firmly with both hands for a few seconds. If it feels cool, heavy or clammy, or you feel small hard lumps, it needs more time in the dryer.
A fully dry pillow feels light and even all the way through, and the clusters move freely when you shake it.
3. Choose a breathable bag
Use a cotton storage bag, a canvas bag, or simply a clean cotton pillowcase or duvet cover. Cotton keeps out dust and light but still lets air pass, so any trace of humidity can escape instead of building up around the fill.
Size matters. The bag should close easily with the pillow at full loft. If you have to press the pillow down to zip it, the bag is too small.
4. Pick a cool, dry spot
An interior linen closet or a high wardrobe shelf is ideal. These spots usually stay close to room temperature and sit away from outside walls, where condensation can collect. Keep the pillow off the floor, where dust and moisture gather first.
Humidity is the thing to watch. The EPA advises keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, to help keep mold from taking hold. A small humidity gauge on the closet shelf will tell you quickly if your storage spot is a problem.
5. Give it space and check in
Store the pillow flat with nothing heavy on it. Folded towels on top are fine. Boxes, suitcases and winter coats are not. For storage longer than a few months, take it out once or twice a season, shake it, let it breathe for an hour and put it back.
Should down pillows be stored in plastic?
No. Plastic bags and sealed tubs trap moisture with the pillow, and down has no way to release it. Even a pillow that went in dry can pick up a musty note after a few humid weeks in a sealed bag. The plastic a pillow ships in is meant for the trip to your door, not for months on a shelf.
If you need a hard container to keep out pets or pests, put the pillow in a cotton bag first and then into the bin. Leave the lid slightly open so air can move.
Can you vacuum seal a down pillow?
You can, but for anything longer than a short move, we would not. Vacuum bags squeeze out the air that gives down its loft and hold the clusters crushed together. A pillow compressed for a few days usually recovers with patience.
A pillow left flat in a vacuum bag for months may never get its full height back. Any moisture sealed in with it has nowhere to go either.
When moving house, the sensible middle ground is to compress the pillow only lightly and open the bag as soon as you arrive. Shake it, let it rest in open air, and give it a day or so to look like itself again.
Storage options compared
Not sure which container to use? Here is how the usual containers compare, and you probably own most of them already.
| Storage option | Airflow | Effect on loft | Good for down? |
|---|---|---|---|
| Cotton or canvas storage bag | Good | None if the bag is roomy | Yes, the best choice |
| Clean cotton pillowcase or duvet cover | Good | None | Yes, a free and easy option |
| Fabric storage box with zip lid | Fair to good | None if not overfilled | Yes |
| Plastic bin with lid left open, pillow in a cotton bag | Fair | None | Acceptable when you need protection from pests |
| Sealed plastic bag or tub | Poor | None, but moisture builds up | No |
| Vacuum storage bag | None | Heavy compression | Only for a short move |
Where should you not keep stored pillows?
Some of the handiest spaces in a home are the worst places for down.
- Basements. They tend to be damp, and down soaks up that dampness slowly over the months.
- Attics and lofts. Summer heat and winter cold swing hard, and condensation can form when the temperature drops.
- Garages and sheds. Damp, dusty and easy for insects and rodents to reach.
- Under the bed on a bare floor. Fine in a dry room inside a breathable under bed bag, but not loose on carpet or floorboards.
- Next to a heater or a sunny window. Direct heat and strong sun can weaken the cotton shell over time.
If a cupboard on an outside wall feels cold or smells stale, move the pillow somewhere more central.
How do you keep stored pillows from smelling musty?
Musty smells nearly always come from moisture, so prevention means keeping things dry. Store only fully dry pillows, use cotton rather than plastic, and pick a room that does not feel damp. In a humid climate, a few silica gel packs or a cedar block on the shelf beside the bag can help.
Skip scented sprays. They hide a smell rather than fixing it, and they add moisture of their own.
If a pillow smells a little stale when you take it out, air it first. A few hours in a breezy, shaded spot often clears a light smell, and a short tumble on low heat with dryer balls helps too. If the smell stays, the fill has likely held moisture, and a full wash and slow dry is the fix.
Bringing a pillow back after storage
Take the pillow out a day before you need it, if you can. Down needs a little time and air to lift again after sitting still.
- Open the bag and shake the pillow firmly from each end to separate the clusters.
- Press and release it from opposite sides a few times. This is the same fluffing routine we suggest for daily use, and it pushes the down back into the empty corners.
- Leave it on a bed or chair in a room with fresh air for a few hours.
- If it still looks tired, tumble it on low or no heat with two or three dryer balls, then shake again.
- Put a clean protector and pillowcase on before anyone sleeps on it.
A healthy down pillow should bounce back to close to its old height. If it stays flat, lumpy or heavy after all of that, the down may simply be near the end of its life. Our guide on how long down pillows last and when to replace them explains what to look for.
Storage tips for guest rooms and seasonal swaps
Most spare down pillows are kept for guests or swapped out for a lighter pillow in summer. A few small habits make that easier.
Keep each spare in its own bag with a protector already on, so it is ready for a guest in seconds. Write the size on a strip of tape on the bag. A standard (18 x 28 in), queen (20 x 30 in) and king (20 x 36 in) pillow look much alike once bagged.
Keep the matching pillowcases folded beside them, not inside the pillow bag. And give every pillow coming out of use the same routine: wash or air, check it is dry, bag it loosely, shelf it. Once it becomes a habit, it takes about five minutes per pillow.
If you are replacing a tired spare rather than storing it, our goose down pillow with a down-proof cotton shell comes in all three sizes and is covered by a 30-day return policy from delivery. You can browse the rest of our hotel-quality pillows and bedding as well.
Frequently Asked Questions
How do you store down pillows long term?
Wash or air the pillow, make sure it is completely dry, then place it loosely in a roomy cotton bag on a shelf in a cool, dry closet. Keep heavy items off it and air it once or twice a season.
Can you put down pillows in vacuum bags?
Only for a short time, such as a move. Long periods of vacuum compression crush the down clusters and can leave the pillow permanently flatter, and the sealed bag also traps any moisture inside.
Is it OK to store down pillows in a plastic bin?
A sealed plastic bin is not ideal because it traps humidity. If you need one to keep out pests, bag the pillow in cotton first and leave the lid slightly open so air can circulate.
Do down pillows need to be fully dry before storing?
Yes. Any moisture left in the center can cause clumping and a musty smell after weeks in a closet. Squeeze the middle of the pillow, and if it feels cool or heavy, dry it longer before putting it away.
How do I fluff a down pillow after storage?
Shake it from each end, press and release it from opposite sides, and leave it in open air for a few hours. If it still looks flat, tumble it on low or no heat with a few dryer balls.
Is the attic a good place to store pillows?
Usually not. Attics get very hot in summer and cold in winter, which can lead to condensation and damp fill. An interior closet at normal room temperature is a much safer choice.
Can you store feather pillows the same way as down pillows?
Yes. Everything about how to store down pillows applies to feather and blended pillows too: clean, fully dry, a breathable bag, a cool dry room and no long term compression.
