We purchased the Quilted 0.5 in Polyester Mattress Topper. It offered a nice barrier between us and the mattress. 

It looks like my review is going for a product that shows a 3-inch thickness and that has received complaints because it's not 3 inches. Well, that could be because it's only half an inch thick if they're receiving the same thing I ordered. Looks like someone inadvertently combined the information for two products into one. If you're looking for a regular mattress pad and not a thick topper, this appears to be the product for you.
