Very satisfied.  Arrived in good time and perfect condition.  Gave it two full days to expand, which it did fully.  With chronic lower back pain I've generally gone with firmer mattresses in the past, but took a chance on this because of its good reviews, and it did not disappoint.  The gel top is soft, yet the coils provide good support so it's very comfortable.  Takes a little getting-used-to, but my back actually feels better.  Recommended.
