We only bought six because our first home had a very small dining room.

Make end chairs fabric and big like a wing back. Will give your table a whole new look. Then you have enough chairs.

Wing back chairs on the ends would leave you with four armless side chairs and two arm chairs for the sides of the table. You might consider adding two fully upholstered armless chairs to put in the middle on the sides, See if the same fabric you have on your existing chairs is available from Bernhardt. In the past I have been able to get fabric from them several years after the original purchase. Alternatively, consider getting four armless upholstered chairs in the existing fabric (or a complimentary fabric) and alternate around the table, then use the arm chairs from the dining set as occasional chairs in the living room.
