Maybe someone can explain to me what is so terribly wrong about a little bridging? Once you are in the saddle, does the bridging go away? I am not sure I would want the part of the saddle where my seat puts the most weight to be the lowest part of the saddle. Just wondering.[/QUOTE]
Bridging changes the weight bearing area of the saddle. Instead of spreading the rider’s weight over the entire length/breadth of the panels, pressure is concentrated at the front and rear, which can (and often does) cause soreness. Because saddle trees are rigid, a bridge does not “sink” into the back under rider weight.
To test the importance of as much weight-bearing area as possible, think of someone wearing one high-heeled shoe and one sneaker standing on your back. Same weight on both feet, but you’re going to feel the high heel more because the pressure is concentrated in that much smaller area.
A very slight bridge can sometimes be fixed by using a shim pad in that area. But because it’s often difficult to fit a shim exactly to the area that needs better contact with the panels, it’s more correct (with better results) to find a tree/panel shape that truly suits the horse’s conformation.
