The tree in this saddle has been technologically designed to allow room for the muscle mass found at the thoracic part of the trapezius (base of whither). This is usually created by correctly schooled horses that are in top level/advanced work, but can also be found in Lusitano, Andalusian and some Warmblood horses naturally.
The Tonisha Supreme comes as standard with 'cupped blocks' in contast to the Tonisha's flat pads as well as having a higher cantle to give the rider a deeper secure seat.
