The instructions are virtually not there! So when I came across a problem, I had to write to Wayfair... could not find a phone # anywhere. No help from the email to them. STILL no answer. Thank goodness I managed to take things apart and fix the problem (sort of) on one chair the holes do not line up, I wired it! I don't think I 'll buy any more self assembly pieces from them with out a help number.
