We have one chair with a "wrinkle" in the back. The other one has a nice "Tight"back. The material is to "Loose" in the one. Hoping it may work out after a few days. So far (2 days) still very noticeable. Also the delivery was disappointing in that a knock on the door at 8:30 got me up for delivery. They called on my cell (Was downstairs) said "we are delivering in 10 - 15 Min. I was expecting maybe a day before notice. An E.M. or call would have been appreciated. I will try to send picture on you business line Not sure how to send here.
