These chair covers are really easy to use. Just take one out of the pack and drape it over your standard folding chair. They're great for sprucing up weddings, parties, or any event. When it comes to cleaning, you can wash them in warm water and use bleach if you need to. Then, dry them at a low temperature. You can use these covers again and again. But remember, they only fit standard folding style chairs, not banquet style or larger LIFETIME folding chairs.
