I really liked the chair.  Very comfortable.  Two reasons why I didn't give it a 5 star... (1) the directions to install the back didn't work.  Very frustrating trying to install the back per the written directions.  The problem is the cushions would not allow the bottom screws to line up.  I finally figured out that if I installed the top screws first, the bottom screws went in very easy and the back was installed.  The written instructions should be changed.  (2) The tilt tension is very hard (almost impossible) to reach/adjust while sitting in the chair.  I had to get out of the chair to make an adjustment.
