Washable chair covers (Oswestry SY11)

This is for a friend, 2 soft grey chair covers for wing backed chairs. They're quite big, too big for my wing backed chairs. They also have cushion covers to go with them. They're in lovely condition but don't fit her new chairs. I've measured the top between the wings and its 81cm. So you would need to measure the top of your chair between the wings.
