This is a great chair.  Comfortable and seems to be very well made.  It's not easy to find a swivel chair.  It came in one box.  It was so easy to put the 2 screws into the bottom to keep the chair back secure, not to mention there are 2 metal brackets to slide the chair back onto.  It is very secure, the swivel is perfect, it sits at a perfect height....I love it.  Glad I bought 2 of them!  Great buy!!
