Replacement seats are used in chairs that originally had a caned seat, a wood seat, or a leather seat. Both fiber seats and leather seats have an embossed design. Fiber seats can be stained and in doing so they take on a leather-like look for a fraction of the cost. You will notice that our patterns are labeled as "flat" or "dipped". The flat patterns will work on any chair regardless of the size of the hole in the seat. If you are going to purchase a dipped pattern, be sure that the size of the pattern is smaller than the size of the hole in your chair.
