I like the fact that the arms swivel up and out of the way when I get out of it from my desk. I can also push it under my desk easier because of that feature. I do wish I could raise or lower the arms without raising or lowering the whole chair. The chair is very comfortable.
I’m not a very large person in the least - probably medium in stature - and this is such and uncomfortable chair. Mine had screws in the seat that dug into my backside which is quite unlike the one in store. It was also quite warm while sitting in it.
