This is a great product!  We had ordered a mattress and it was really too hard so we decided to try the Gel Memory Foam mattress topper t soften things up.  When our full size (79"Lx59"W) arrived, we placed on our queen size bed to allow it to open up and take shape. I bought a similar product a few years back and this topper is of much better quality. The topper adds a great deal of comfort and it's reversible! Looking forward to switching it up. Our guests have said they have had a nice sleep.
