We received the product in two days.  Very surprised!  In two weeks one of the casters broke and we had been unable to use it.  We called the chair company and they promised to send us a new set right away.  We are still waiting even though we have called again.  Perhaps you could help us with this. We may ask for a refund if we are not able to use the chair very soon.  We would like some resolution with this!!!!
