I *heart* mine!
It is fairly solid as memory foam mattresses go though, so you're not sinking right into it.

As a comparison, I went off to uni and had to leave my lully mattress back at my parents. The one in the student digs was an apparently new but exceedingly soft sprung mattress, sitting on it was like rolling around on a water bed. I fell ill, and spent a lot of time lying down - I got cramps in my back and legs and bruises on my hips from the springs. Eventually ended up in hospital, and despite the rubber sheets making me sweat like a paedo in a primary, the memory foam mattresses did not cause even half as many problems.

You go hospitalised by a mattress?
