With these pillow protectors you can Rest easier with out dust mites bugging you. The doctor recommended for allergy purposes so we got some for all the pillows we use. They seem to be good quality. Standard size worked for all of our pillows, but one memory foam pillow was a bit of a tight fit. So, if you have oversize pillows at all, I'd recommend the bigger size.
Very comfortable cover with terry cloth exterior and waterproof material lining the inside which makes four a comfortable product that does its job! I also used my Shop Your Way points and that coupled with the sale price made it extremely reasonable and worthwhile! I will be buying more!
