We ordered two of these chairs to see if we liked them and to replace some older chairs in our dining area.  They arrived in perfect condition, were easy to put together.  They are very comfortable, roll and swivel easily.  We really like them and are going to go ahead and buy some more to complete the chairs in our dining area.  The only reason that I gave them 4 stars instead of 5 is that they are just a little on the light side, not quite as heavy as I would have liked
