A tree configuration for use in combination with an exercise or racing saddle. The tree is formed by injection molding with a thermoplastic material that results in a flexible, durable, symmetrical and smooth surface entity. The flexibility of the material prevents undue stressing of the tree at points where certain extended members are attached to the main body and, the members return to their original state after usage without maintaining a permanent spread or set. The smoothness and memory characteristic of the material result in minimal damage to the leather portion of the saddle.
