I've been using both mattress and pillow protectors for years on my allergists' advice. I've used several brands over the years and the AllerEase Ultimate Cotton is a clear winner. The soft top cotton fabric is soft and cool to the touch and the standard/queen fits my thick pillow easily. I've used so many pillow protectors that were hot, felt plastic-like, and in some cases even had the annoying crinkly sound. The AllerEase just feels like a good quality cotton sheet and it washes up nicely. I love that the fabric is also antimicrobial to prevent odors and bacteria. Next time I need to replace my mattress cover I'll be ordering AllerEase for that as well.
