I purchased these for my Emotional Support Animal because he will get on my bed with me when I am having one of my “panic attacks, emotional spells” and comfort me as much as he can. They seem to work great protecting my bed. They are very large and two comes in the pack. He will voluntarily lay on them with no problems. And my bed linens are protected just in case of an accident. This is a great purchase! Glad I made the decision to order these. I would definitely  recommend to anyone.
