I give it a one because they look and feel very cheap.  They do "NOT" feel or look like they are water resistant to me!!  I am not about to throw water on my mattress, I did put them on the mattress and will keep them.  Too much trouble to sent them back and I needed them for company ASAP.  Not what I expected,disappointed on this item. They do cover the whole mattress, but will tear very easily.
