Sad to say we had to send these chairs back.
We felt as though there was a defect in manufacturing. Three different adults of varying sizes sat in these chairs and everyone said they would be unable to sit in them because the lower portion of the chair stuck into your lower back. So, like I said unfortunately we had to send them back.  They are beautiful chairs and maybe someone else would have luck with them.  I was sad to let them go. Keep on looking.
