The AllerEase Maximum Allergy and Bedbug Mattress Protector is an excellent cover for my Queen sized mattress and is amazing at preventing allergy flairups during the night.  I installed it and noticed a difference in the allergic reactions I have during the day and night as I am allergic to mold and other allergens in the air.  This product is lightweight, easy to install and has the added benefit to health.  I totally recommend this product for its benefits and easy installation.
