Saddle Top Rider J - Top rider J saddle for sale. The saddle is in good condition. It should be soon and the girth straps on one side are also soon to be repaired. The seam on the seat has opened up a little. (See pictures) I bought the saddle with my horse about three years ago. I estimate the saddle has about 17.5 inches of seat and is very comfortable. It lay well on my round-ribbed Isis mare. Just let me know if you have any questions! :)
