Store Outdoor Cushions for the Winter

Cushions left outside through winter come back streaked with mildew, split at the seams, and smelling like wet cardboard. The fabric fades unevenly where snow sat longest. The foam inside compresses into permanent divots or crumbles into foam dust that never reconstitutes. A hundred dollars of outdoor furniture cushions becomes garbage because storage felt like too much work in October. Proper storage is not complicated, but it is specific. Cushions need to be bone-dry before they go away, they cannot touch concrete directly, and they absolutely cannot be stored in conditions that cycle between warm and cold. Do it right once in fall, and your cushions come out of storage in spring looking like you bought them yesterday. Do it wrong, and you are shopping for replacements before Memorial Day.

1. Remove Dirt and Stains First. Use a stiff brush to remove dirt, pollen, and dried leaves from fabric surfaces. Mix one tablespoon of dish soap with warm water and scrub any visible stains with a soft brush. Rinse thoroughly with a garden hose until water runs clear and no soap remains.
2. Dry Every Surface Bone-Dry. Stand cushions on their edges in full sun, rotating every hour so all sides dry evenly. Press down on the foam to check for moisture—if any water squeezes out, keep drying. Even slight dampness trapped inside will turn into mildew during storage.
3. Dust Every Seam and Edge. Once dry, use a vacuum with an upholstery attachment or a clean brush to remove dust that settled during drying. Pay attention to seams and piping where dirt collects. This step prevents grit from grinding into fabric during months of storage.
4. Seal and Label Everything. Use clear plastic bins with latching lids, or vacuum-seal bags if you need to save space. Do not overstuff—cushions should fit without being compressed more than halfway. Label bins by furniture piece so you know which cushions go where in spring.
5. Keep Bins Off Cold Floors. Place bins on shelves, pallets, or scrap lumber so they sit at least four inches above concrete floors. Choose a basement, heated garage, or indoor closet where temperature stays relatively stable. Avoid unheated sheds or attics where temperature swings cause condensation inside bins.
6. Catch Problems Early. Open one bin in January or February and check for condensation, musty smell, or mildew spots. If you find moisture, remove cushions, dry them indoors, and switch to a drier storage location. This five-minute check can save you from discovering ruined cushions in April.
