Verdict is still out on this one since the right arm assembly was delivered broken. Looks like it will be a nice chair but will have to wait for the replacement part.  The back is attached via the arm assemblies so until the replacement part arrives, it's unusable.  The process on Wayfair to report and request a replacement part was very easy.  The initial auto-response estimates 2 weeks for delivery.  Hoping it arrives sooner.
