Using these outdoor patio chair cushions is a breeze. Just place them on your wicker patio chairs and use the long shoestring style ties to secure them. When you're relaxing on your patio or by the pool, they'll provide a super comfortable seating experience. As for maintenance, since the covers are removable and zippered, you can easily take them off. If they get dirty, simply wipe them clean with a damp cloth. The cushions are made of fade and weather - resistant materials, but it's still a good idea to store them indoors during extreme weather conditions to extend their lifespan. And remember, the item description might refer to features of other variants, so check carefully if you're looking for a specific fabric pattern or shape.
