The back rest is nice, but they definitely aren't made for all summit stands. It doesn't fit my viper steel stand like the open shot summit shown in the video. The back rest is basically floating with the straps holding it in place. Had to leave it a little loose so that I could still pack my climber. It was in the way otherwise. It's still comfortable. From what little I can tell it's there, but definitely not what I was anticipating.
