1. The foam material of the saddle, although thick, is very soft, (misleading photos, which looks tighter), as a result of which it does not hold the body firmly.
2. Settings for the footrest unacceptable. The last hole in height should be the first one. We are supposed to use the footrest to bring the leg 90° in relation to the body so that the musical instrument does not slip off the leg, without the need for a belt. I'm 1.87cm high and with the saddle at the lowest point and the footrest at the highest point (and only then) comes the 90° leg. It's like using a short chair and not a stool. Imagine what happens to someone shorter. I performed my first live with this particular saddle which lasted 4 hours. One hour you can tolerate it. From then on, you are constantly looking for a place to rest your body but in vain.
