Mattress is exactly as advertised.  Packaged very well.  Place the mattress wrapped in its plastic bag on the chosen foundation and unwrap it there, you will find it easier to install that way.  Mattress expands fairly quickly once unwrapped.  When fully expanded, the mattress is very comfortable, with medium firmness.  Another notable positive feature is how well it supports when you sit on its edge with your feet on the floor, it does not distort or sag at the edge.  The overall quality is very economically priced.
