I purchased this item thinking it was a mattress protector because it says "mattress protector" in the name. When it arrived, the packaging clearly identified the item as a "boxspring encasement", not a mattress protector. I had noticed that the words "boxspring encasement" were in the title, but because "mattress protector" was as well, I thought it could be used for both purposes. One of the reviews lead me to believe this as well. This item should be renamed on wayfair's website. I am very unhappy with this item as it is not what I was trying to order.
