While the chairs have been great (in the short time we have them), the delivery process was flawed. The two chairs were shipped in six boxes and delivered to us three at a time. And those boxes were mixed so that even when we got the initial three boxes, they were parts from both chairs so we could not even setup one chair until all the remaining boxes were received. Easy setup when all boxes were here. Comfortable, work well. The only issue with the chairs is the imprinting on the main control. It is IMPOSSIBLE to read the names printed on the control. However four stars due solely to shipping issues.
