Turns out to be cheap Chinese made.  The tabletop inserts are thin and not sturdy.  We will avoid putting heavy plates on it, or elbows.  One tabletop insert arrived broken, the packaging from the manufacturer: Alpha Mart Holdings LLC, says contact the manufacturer for any problems or warranty claims.  I did, and they said to contact Wayfair and refused to honor the warranty.  Wayfair came through with a proper follow-up, hats off to Wayfair.  Won't buy from Alpha Mart Holdings LLC again, not upstanding people.
