Pro...Very fast delivery (less than a week cross country).  Simple assembly without any help.  Feels comfortable and supportive for my back.
Cons...Noticeable chemical (petroleum?) smell that after a few hours gives me a headache.  Put it together three days ago and the smell is still noticeable and can even be smelt on my clothes.  Leaving the chair in an out of the way place with ventilation and will see if/when the smell dissipates enough for me to use the chair.
