I thought I would love this full size memory foam mattress and topper from the reviews I read. Unfortunately that was NOT the case. I have an old memory foam that I wanted to replace. The one I just ordered was way too soft - should have figured that out since the box was only 19 lbs. My old one (also from Overstock) was about 40 lbs. - much more dense. And the gel substance in the topper reflects my body heat back so I would wake up sweating. This is not something I want - especially now that Summer is coming. I can't really return it - there is no way I will get this back in the box. I am going to use it in my spare bedroom. First item I have ever bought on Overstock that I did not like.
