This is a very well made cover. I was very impressed with the thickness (far more heavy duty than I was expecting). I went with the 40 inch version for a 36 inch fire pit.  I think now I would have been fine with the 36 inch one but didnt want to have to stretch it out to make it fit. Only time will tell how it holds up to sun and weather but I would definitely recommend this for anyone looking for a fire pit cover.
