We absolutely love this mattress. We have had the old box spring type of mattresses for years and thought we'd try something different as our other one only held up for less than 3 years. I love how it cradles our bodies. It's firm but not so firm that it's hard to sleep on. I loved how easy it was to put up too. We bought a king size and my husband could put it up all by himself and didn't need any help.
