I wanted a pillow protector that would also be comfortable, but this one has too much of a polyester feel, so I will use them for the pillows I put in shams that won't get slept on. I will get more for my other guest shams, though.  At least it will cut down on allergens for my guests. 

Pros: They provide solid protection.
Cons: I don't think they would be comfortable for sleeping pillows.
