We received the chair and put it together. The wheels do not function correctly in that they lock up trying to move in any direction. The resulting frustration is over the top, as the chair itself is fine. We approached Wayfair Customer Service for assistance, assuming they would simply send us replacement wheels. Not the case. We were given two completely unacceptable options, basically leaving us with a useless chair. They are unable to replace parts. Our high opinion of Wayfair has dramatically sunk! They simply could not provide a simple fix and retain a satisfied customer.
