The bolts came stripped and since I am a sr. living alone returning something so large would have been a problem.  Since it's not put together well it's headed to the garbage when I can afford to buy again.  Really disappointed with this.  Thank goodness I have had nothing but success with Wayfair. CA.  If this had been my first purchase, I would have never bought again.  A true disappointment.  I spend a lot of time at the computer and had great expectations for this chair.
