Good Product
Doesn't change a bad mattress to a good one, but definitely helps.  I purchased the &#34;upgrade&#34;  of a previous Consumer Reports &#34;best buy&#34;, which did not hold its shape, sagged in only a few months (and is no longer even recommended by CR).  Mattress was from a major manufacturer and very expensive.  I could not afford another purchase.  This product definitely helped the back pain and improved rest.
