I go it on sale. It is very comfortable. I am a very big guy (both vertical and horizontal) and I fit great. No adjustable arms but I never really used those in my last chair.
I've found this chair to be very comfortable even using it for up to 10 hours at a time. The chair was easy to assemble with well written instructions and all the parts were labeled in their own packaging for each instruction step. I have another office chair which I'll need to replace soon and will definitely purchase this product again.
