I was very disappointed in this slip cover.  My chair fell well within the measurements listed for this cover. It was next to impossible to get it on and it wouldn't even reach to the bottom of the chair and stay.  It kept popping up the sides every time.  My biggest disappointment is that I paid 20 additional dollars for faster shipping and it arrived a week earlier than promised (kudos) but made me realize that the additional $20. was an unnecessary expense. It would have made it here in plenty of time with regular shipping.
I will say it was nice looking and the fabric is great, but the design is poor.
