This is as much about Wayfair's "pro" assembly service as the furniture.  My "pro" canceled the day of the appointment, after the appointment had been scheduled for close to a week.  Wayfair offered no courtesy for the inconvenience other than to offer to reschedule or cancel (thanks!).  If that's the best Wayfair can do, then I'm going to think twice before ordering from them again.  It took us 4 hours to put the piece together - and it seems okay.  Doors scrape the bottom when opening/closing, scratching the veneer and they were very tricky to install.  A two-person job.
