I haven't tried the one delivered on this order yet, but I had purchased one with the bed originally. I got the second one so that I can change it out on the bed and have time to wash and dry the one off the bed. They are a real lifesaver. Coffee and/or tea spills, grand kids' bed wetting & upset stomachs (I don't have grand kids, but if you do, you know whereof I speak), cats' & dogs' upset stomachs (and, as they get older, less-reliable bladders); heck! OUR less-reliable bladders as we get older. This cover has stood up to everything we've thrown at it while keeping the mattress underneath pristine. It seems awfully expensive for what it is, but since it does the job, I'm willing to pay it. Good product.
