This is the best office chair that I have ever owned!!!   This chair is very well built and will most likely be the last chair I will ever have to buy.  I can sit in it for hours and feel great.  The cushioned seat is amazing.  My business partner has one also and he sits in his chair for 12 to 14 hours 7 days a week and wore out the last chairs cushion in about six months you can't go wrong with this chair!!
