I bought three chairs for the office. They were delivered on time (in fact a day early) in good shape. The packaging was a little scared but the chairs were fine except one had a slightly broken plastic trim cover used on the pneumatic center post.  They went together easily and look great.
However the I am a little disappointed in the performance. I am 6' 1" 190 lbs and after a short time I seem to bottom the seat cushion and they squeak when rocking. I use an inch or so thick foam seat cushion and lubricated the pivot joints and this is working. But for an allegedly expensive chair these fixes seem inappropriate.  I decided to keep them though, hope they hold up.
