I have been trying this out for a few weeks now and I am really impressed. I was a little skeptical at first, but its really comfortable and works perfectly. It will be great for the colder months, especially. Its easy to put on your mattress, it fits nicely and its very well made. I would absolutely buy another one for my daughters bed. I love that its waterproof, too. Also, its simple to wash. I would highly recommend picking one, or two up!
