This was my first experience ordering from Wayfair.  When we received the product the outer box stated Madrid chairs by another company not Charlston.  Once opened reviewed the parts the instructions stated J&K parts for the chair rungs we had F, L.  Once together the rungs were off centre didn't fit well into the pre drilled holes, then when we stood them up there was a 2" height difference the adjustable legs had to be removed all but one to steady these chairs.  The material on two of the chairs was pulled.  When I called Wayfair the gal was very apologetic, easy to deal with but did say these were shipped from the closest dealer not necessarily Charlston.  Let me say Wayfair was easy to deal with I am very satisfied with the end result and I will give Wayfair another try.  So we believe if you are ordering chairs call in to order ask if they will be shipped directly from the manufacturer stated as we believe the chairs received were knock offs and the parts didn't even fit.
