I have not had the opportunity to sit in the chair, because four crucial bolts to needed to assemble were not included in the delivery box.  I called Customer Relations, and talked to a really great lady who helped me solve my problem in about 30 seconds.  The Bolts will be replaced by a Wayfair Sub, but so far, I have not heard from anyone with instructions how this is to be done.  It has now been four days. Help.  I cannot sit in my new chair, and I am required to be at my computer for about 8 hours every day.  SS
