Na wat gesurf op inet staat er op de Amerikaanse site iets over het spul:
Citaat:Stübben has partnered with Biomex Technology Center, the leading hospital for orthopedics and sports medicine in Switzerland, to create an innovative seat design that greatly reduces a rider’s back pain. Introducing the Stübben Biomex... it will revolutionize your idea of a comfortable saddle.
Stübben Biomex is currently available on these saddle models: Maestoso D, Maestoso D Deluxe, Genesis D, Genesis D Deluxe, Roxane S, Roxane S Deluxe, Genesis s Deluxe, Edelweiss NT Deluxe.
Many riders (studies say over half) suffer from back pain, especially after they ride. When riding on a horse, the force exerted on the spine flows mainly through the seat bones. Pressure on these seat bones and the extremely sensitive soft tissues around them can cause pain. The Stübben Biomex cushions the seat bones with two kidney-shaped pads, which absorb impact and relieve spinal stress. In addition, the depression between the kidney-shaped pads also plays a crucial role, as it substantially lessens any possible pressure on the soft tissues surrounding the seat bones (see the oval areas on the diagrams below). In scientific comparisons with conventional saddles, seat pressure measurements at various gaits show that the Stübben Biomex provides much greater relief in the seat bone area and the surrounding soft tissues.
