While easy to assemble and features for arms up and down work as expected, the seat back is much lower than I expected.  The bottom of the seat to top of back is just 25".  I am 5' 7" and the back of the chair where I would expect a headrest to be and looks like in the picture is at top of my back.  Therefore it kind of pokes headrest into my upper back vs. a proper headrest.   Perhaps more of a juvenile desk chair.
