Good medium sized and medium firmness padded leather rocker / recliner of your choosing. Depending on your gaming mood you can lean forward in it, rock it, or recline it if feeling lazy. Also, they stay cooler temperature in summer. Can't beat it. Don't have to go to crazy on cost too and you can use it for other things than gaming. Ashley makes some pretty good ones for 250-300. I'm 6'2" I would stay medium sized though. I think it is awkward for gaming if you get a fully padded gigantic one personally.
