These chairs are junk.  They did not even last 18 months before the webbing started to break.  Wayfair promised to refund this purchase in full on February 23, 2018 (confirmed by e-mail) but never did.  After contacting them again to find out what happened to the credit I was told a supervisor would contact me.  No supervisor ever did.  I then wrote to a number of management people who also never responded.  Need I say more?  Buy from another company.  Wayfair does not stand behind their word.
