This is the second chair I purchased. The first was perfect.  I have use them both at a two person desk overlooking a big window with a fabulous water views.   This second purchase is not so perfect. This one make sound when you sit on it and when you get up.... The wood on the bottom seat is finished a little differently than the rest but no one will ever see the bottom.  The chrome back bracket has rough edges.  Also it did not have the second allen wrench needed to put it together.  Thank goodness I kept it from the first one.   Like I said the first was perfect and I love this style office chair. I am keeping it in spite of the differences. I would welcome Customer Services to contact me to discuss further.
