When I first opened the AllerEase ultimate pillow protector, I was concerned as I thought it was quite stiff coming out of the package.  I decided to wash it first before use, and my concerns went away.  I was worried about the crunching sound when rolling around on the pillow.  Not present after the initial wash.

The zipper on the pillow protector works wonderfully and doesn't stick out to poke you throughout the night.

I do have allergies and sleep with my dog in the bed (I know... poor choice - but I love him!).  I do feel that this pillow case assisted in lessened nighttime sneezing.
