Query: Decent quality for the price.

This mattress topper exceeded my expectations. When I first received it, it was all smushed up from shipping. Initially, I was disappointed, it was too small for my mattress and mishapen. I gave it time to air and reconstitute as recommended by the packaging. After a few hours it was full size and fully puffed up. It makes an amazing difference in the feel of our mattress. My husband noticed the difference immediately, even though I hadn't told him about it. FYI--I have a very good Sleep Number mattress, but it's appearance is a little lumpy, so I bought this purely to give the bed a smoother appearance and was pleasantly surprised at the quality--especially for the price.) I don't know how much difference one would get by purchasing the 3" topper instead of this one, but this one noticeably improved the surface quality of themattress. For the price, this is a good value.
