DeathzThis is a pretty ideal chair for a large framed person. It has lots of room and does not have the hard side bolsters on the seat that are a common feature of a lot gaming chairs so it is very comfortable.
DeathzI am pretty much exactly the same size as you. A little heavier in the weight department, though. I was worried about the room for a large framed guy as well and was very happy with my purchase. Had mine for about 6 months and have no complaints at all! If you're looking for a chair that is good for heavier set guys but is still a "gaming" chair, this is the one to get.
Good luck!
