I bought a Gibson’s half tree exercise saddle for riding out in everyday. It’s comfy and had little use before I bought it. My boss checked the tree and says it seems okay. When I get back from a lot it sometimes dips right down in the middle and has raised at the back, kind of like you’d expect in a dressage saddle. I usually have 2 poly pads and a gel pad under it and recently have added a foam pad too. It seems to be worse if I’m on a wider horse and the more I pad it out incase it’s causing pressure points on their backs the more it dips. Has anyone else had this issue with a half tree saddle? I don’t know if it’s just the saddle or if there is an issue with it!
