Flat stick covers have a rectangular flat, usually wooden, stick inserted at the edge of the sides of the seat fabric. Normally, flat stick seats are wider than the round stick type because they go to the outside of the seat rail where they rest in a rectangular cut out. All of our replacements come with the seat and back covers, plus the sticks. Everywherechair has many options and colors available, you're sure to find the perfect fabric for your Directors Chair.
