I purchased two. I took one out of the box and placed it on the chair. I immediately knew that these were very poorly made. I felt as if there was no cushion at all. They say they are  four inches thick but they must be stuffed with Kleenex. I could feel the hard bottom of the chair. It was ver uncomfortable. I never even took the other one out of the box. I am sending these back immediately. They are a waste of money.
