Patio cushions rarely wear out from a single summer of sitting. They wear out from months of being left outside wet, or from being stored before they were clean and dry. A short routine in the fall — clean, dry, and store somewhere dry — protects both the fabric and the foam inside for the next season.
Clean Before They Go Away
Dirt, pollen, sunscreen, and food spills left on cushion fabric over the winter can set into the fibers and give mildew something to grow on. Brush off loose debris, then clean the covers according to their care labels.
Some covers zip off and are labeled machine washable; others are labeled for spot cleaning or hand washing only. Follow the label for each step separately — a cover that can be washed may still need to air dry rather than go in a dryer. If the cover doesn't come off, a gentle surface clean with mild soap and water, followed by a thorough rinse, is the cautious approach unless the label says otherwise.
Dry the Foam, Not Just the Fabric
The fabric can feel dry while the cushion's foam core still holds water, especially after rain or washing. Stand cushions on their edges in a sunny, airy spot, turning them now and then, so air reaches every side. Squeezing a corner can tell you whether moisture remains inside.
Give them more time than seems necessary. Foam that's stored damp can develop mildew and odors that are hard to remove, and the problem often doesn't show until the cushions come out in spring.
Where to Store Them
Choose a dry place protected from rain and snow: a garage, shed, basement, or closet. Keep cushions off the floor on a shelf or pallet if the space can get damp, and away from anything that could leak on them.
Breathable storage bags, or simply clean cotton sheets draped over a stack, let any remaining moisture escape. Airtight plastic bags can trap humidity, so if you use them, the cushions need to be completely dry first. If a deck box is your storage, check that it stays dry inside through rain and snow before trusting it for the whole winter.
Stacking and Shape
Stack cushions flat rather than squeezing them into a tight space, and avoid putting heavy items on top. Long-term compression can leave foam flattened or creased. If you're short on room, standing seat cushions upright on their edges side by side often uses space well without crushing them.

Quick Questions, Answered
Q: Can patio cushions stay outside under a cover all winter?
Some can, but a cover can trap moisture underneath if cushions are damp. Indoor or sheltered storage is usually gentler on foam over a long winter.
Q: What if they smell musty in spring?
Air them out in the sun and clean the covers per their care labels. If the foam itself smells, it may hold moisture and need thorough drying or replacement.
Before Next Season
When you look for covers, cushions, or storage accessories in Patio Furniture Accessories, check each listing's care instructions and dimensions against the cushions you have.
- Brush off debris and clean covers by their care labels
- Follow washing and drying instructions as separate steps
- Dry the foam fully, not just the fabric
- Store in a dry, sheltered spot, off damp floors
- Use breathable covers and avoid crushing the stack
Cushions that go into storage clean and fully dry come out ready to use. Spend an afternoon on them in the fall, and spring setup becomes a matter of carrying them back outside.
