I looked at several different mattress covers before purchasing this queen size allergy care cotton mattress encasing from the Allergy Store, and I'm happy to say I'm very pleased with it.  I noticed right away that I was sneezing less when in my bed. The fabric is tightly woven but not noisy. It fit perfectly over my pillow top mattress, and best of all, I got the encasement on the mattress without much trouble. I don't know why some of the Reviewers complained about it being difficult to get on and saying it is a two person job, I'm an 80-year-old woman and I did it by myself.
