Here are all the things I like about this chair so far:
The chair arrived in a reasonable amout of time.  
The instructions were decent.  
It feels very comfortable and I do love the back support. 
I also like that if I lean my head back it gives you support there as well.  
It comes with the allen wrench that you need to put it together.

The things that could be conceived as a negative:
The arm rests are padded but not adjustable.  However the height of the seat can be moved to a very high position so I suppose that can be a plus if you are very tall.  
The rubber stoppers keep falling out (to cover the screw holes) and there are no instructions as to how to place them properly. I included a picture showing how they don't really fit into the holes.  (I am probably doing something wrong but again, no instructions)
