I spend most of my day in the classic Aeron chair from Herman Miller, but I almost bought the one you listed here a couple of years ago! For playing these days, I am sitting on my cajon while playing it with a DW5000, so probably the least attractive option out of all!!Herman Miller makes the best chairs IMO. I spend most of my day in one and it is comfortable. It has arms. They have some models with removable arms or none at all.
