These were exactly what I wanted: the right thickness and softness of cotton, and high quality zippers. Just right, and at a price-per-unit that beat those of much lesser quality at a "big box" store. The zippers are at the very end, which I prefer but some may not. These are not the kind with the zippers up on the pillow, a few inches from the end, under a flap that hides the zipper. That kind is great -- until that flap-covered-zipper ends up under your cheek! I think these are better, so long as you lead with the zipper end of the protector when you put the covered pillow into the pillow case.
