This pillow is A1 quality. The zippered cover is made of polyester and spandex so it has a snug fit. The zipper closes easily. I’m always skeptical of the loft of a pillow—too high and it cranks my neck up too low and there is not enough neck support. The fill in this pillow perfectly conforms to my head and neck and adjusts with movement. The fill does not bunch up and stays nicely distributed. It is not as stiff as memory foam. You can see the 
“vented construction which contributes to the cooling quality of this pillow.
