Using these chair covers is easy. Just take one cover and drape it over your standard folding chair. It will fit tightly thanks to its high - elasticity spandex material. When it comes to where to use them, they're perfect for weddings, parties, events, and banquets to add a touch of elegance. Remember, these covers won't fit banquet style chairs or the larger LIFETIME folding style chairs. For maintenance, you can simply put them in the washing machine and then tumble dry on low heat. This will help keep them in good condition for multiple uses.
