These covers look pretty good, but there was a drawback. The actual size of the cover is 19.5 in by 11.75 in. It was difficult for me to squeeze my pillows in, but I did eventually get them in. Unfortunately, the color I ordered (dark grey) did not work for where I needed it. So, I'll be returning them, both sets. (I rcvd 2 sets of these Zermeno Lumbar pillow covers, in two colors. But, not the other pillow covers I actually ordered. After following up, I eventually received the correct set I ordered, about a week later.)
