I dont really think it exists or atleast isnt common. I've bought several seats over the years. The last one that I like the best is the director style chair the folds out side to side. It seems to be the most comfortable anyhow. I also cary one of the inflatable seat pads for use on the seat or seat back if need be. But its far from perfect - I had to add my own backpack straps to it. Plus you sit pretty far back in it - might be hard to shoot out of it.
