Used indoors. Since it was used frequently, please refrain from purchasing if you are looking for a pristine item. There is a stain on the upper left of the seat surface in the second photo. There is black dirt on the back of the seat in the third photo. There are scratches in the fourth photo. There are adhesive marks from felt stickers in the fifth photo. There are scratches on the pipe connections on the back in the sixth and seventh photos. I am not considering lowering the price at this time. Thank you.
