Fairly straight forward assembly.  Very comfortable.  Top seat height is lower than I expected  ... measurement provided  is to the top of the cushioning and not bottom of  chair so if you need something higher, this is not the chair for you.  The "massage" function is nice but not significantly effective.  Heat in the lower back is a lovely welcome addition.  Button meant for adjusting the tilt does nothing.  For the price, all in all a good chair.
