We asked the question, what does the horse want from a tree?
The answer is a means to distribute the rider weight symmetrically and evenly on the 7th to the 18th rib. This means there should be no flexion in the tree front to back.
However, as a horse moves, its’ shoulders need to find more space as the scapulae rotate back under where the tree sits.
The answer is to let the head of the tree swing from side to side as the alternate shoulders rotate back under the tree.
In other words, a horse would want a saddle that is longitudinally rigid and laterally flexible in the head. This is exactly what the WOW™ tree with what we call “Lateral Flexion™” does.
