I was so happy to finally find white covers to fit my thick cushions. The bottoms are overall a bit larger; however, the zipper opening is shorter than the actual length. So, in order to get my cushions in without tearing anything, I had to remove a piece of my cushion's foam core to get them inside the cover, and then replace the foam. A bit of a pain...which is why I'm giving them 4 stars instead of 5. BTW, the top covers fit perfectly!
