I purchased one a while ago, and I just don't have the time nor the desire to learn saddleseat (the chair-position thing contradicts my dressage training). It is black, 21in. Deep seat (I believe this means it is more of a "equitation" style saddleseat saddle). No clearly discernable brand on this saddle.
I only used this saddle twice. Actually, I think it was just once... It was really comfortable (I've ridden in a few saddleseat saddles - this one is definitely the better of them).
Asking $100, will consider other offers.
If interested, I can send pics!
